Given:
The price of a share of stock in JZMobile was $74 two weeks ago.
Seven weeks ago, the price was $59 a share.
To find:
The linear equation to find the price p of a share of JZMobile w weeks from now.
Solution:
Let, p be the price of a share of JZMobile w weeks from now.
The price of a share of stock in JZMobile was $74 two weeks ago. It means, the graph of linear equation passes through (2,74).
Seven weeks ago, the price was $59 a share. It means, the graph of linear equation passes through (7,59).
The graph of linear equation passes through two points (2,74) and (7,59). So, the linear equation is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-74=\dfrac{59-74}{7-2}(x-2)[/tex]
[tex]y-74=\dfrac{-15}{5}(x-2)[/tex]
[tex]y-74=-3(x-2)[/tex]
[tex]y-74=-3x+6[/tex]
Adding 74 on both sides, we get
[tex]y=-3x+6+74[/tex]
[tex]y=-3x+80[/tex]
[tex]y=80-3x[/tex]
Therefore, the correct option is C.
Alex counted to 2400 by 6's beginning with 6. Matthew counted to 2400 by 4's starting with 4. How many of the numbers counted by Alex were also counted by Matthew?
Answer: 200
Step-by-step explanation:
Number of numbers counted by Alex;
= 2,400 / 6
= 400
Number of numbers counted by Matthew;
= 2,400/4
= 600
Numbers that both of them counted = 600 - 400
= 200

One British pound was worth 1.5761 Canadian dollar.If a hotel room coat 126 pounds,what must be paid in Canadian dollars.
Answer:
198.5886 or technically 198.58 or 198.59 because you can't have a decimal of a penny.
Step-by-step explanation:
One British pound was worth 1.5761 Canadian dollar, meaning that every pound needed is worth 126 Canadian dollar.
That means you can multiply 1.5761 by 126 to get the Canadian dollar price.
126 x 1.5761 = 198.5886
198.5886 is the Canadian price

Mrs. Maxwell is teaching a 5th grade class. She is standing 9 meters in front of Bruce. Ruth is sitting to Bruce's right. If Ruth and Mrs. Maxwell are 15 meters apart, how far apart are Bruce and Ruth?
9514 1404 393
Answer:
12 m
Step-by-step explanation:
The distances of interest are the sides of a right triangle whose right angle is at Bruce. The hypotenuse of the triangle is the Teacher-Ruth distance. The unknown side (x) can be found using the Pythagorean theorem:
x² + 9² = 15²
x² = 225 -81 = 144
x = √144 = 12
Bruce and Ruth are 12 meters apart.

Write the following inequality in slope-intercept form.
12x - y > 17
Write your answer with y first, followed by an inequality symbol. Use integers, proper
fractions, and improper fractions in simplest form.
Answer:
y < 12x - 17
Step-by-step explanation:
The slope-intercept form is generally represented as;
y = mx + c
where m is the slope and c is the y-intercept
Thus, we have in this case ;
12x-17 > y
flipping this , we have ;
y < 12x - 17
Architectural Designers is creating a schematic for a bridge over the Columbia River whose arch is in the shape of a parabola. The road, 40 feet above the river surface, represents the directrix of the parabolic arch. The focus of the parabolic arch is located 20 feet above the river surface. In the schematic, the river surface will be positioned along the x-axis and the axis of symmetry for the downward opening parabolic arch will be positioned along the y-axis. Which equation best models the parabolic arch in the schematic?
Answer:c
Step-by-step explanation:
A and D are incorrect just by the fact that they dont open downward(arch) B. Is also incorrect because the y intercept 10 doesn’t include the focus point 20 also u can use this calculator called parabola calculator to pin point focus and directive just in case u want to check my answer. C is most correct because it has intercept 30 including focus point 20...(SHOUT OUT TO ILT)

What biotic factors do the organisms in Movile Cave rely on?
Answer:
Step-by-step explanation:
Trees or grasses may be growing around the entrance of the cave, and there might possibly be rocks around the side as well.
The most common plants in caves usually grow in the most moist parts and they are:
- Mosses (small flowerless plants that usually grow in dense green clumps or mats, in damp or shady locations)
- Ferns (flowerless plant that has feathery or leafy fronds and reproduces by spores released from the undersides of the fronds. Ferns have a vascular system for the transport of water and nutrients.)
- Liverworts (small flowerless green plant with leaf like stems or lobed leaves, occurring in moist habitats. Liverworts lack true roots and reproduce by means of spores released from capsules.)
These species can live at the entrance zone or in the twilight zone.
If you go into the twilight zone, cyanobacteria (a bacteria that has chlorophyll) causes all the rocks facing the entrance to be a shade of green.
All cave animals and organisms fit into three categories. Placement into these categories depends on how much time the organisms actually spends in the cave.
The first type are known as Trogloxenes. You can think of trogloxenes as cave vistors. They come and go at will, but use the cave for specific parts of their life cycle (hibernation, giving birth, etc.) Although it spends specific parts of their life in the cave, it will never spend a complete life cycle in the cave. Examples of animals that are trogloxenes are:
-Bats
-Bears
-Skunks
-Raccoon
-Moths (sometimes)
Troglophiles are the next level. These are organisms that survive outside the cave, but may prefer to live outside of it. They leave the cave only in search for food. A troglophiles can chose to live its entire life either inside or outside of a cave. Some examples of trogphiles are:
-Beetles
-Worms
-Frogs
-Salamanders
-Crickets
-Spiders
-Crayfish (sometimes)
Troglobites are animals that live in the cave but do not come out. They often have physical adaptions to the cave life like no vision, or loss pigment because light does not reach this part of the cave. Examples would be
-Snails that have thin white shells and small eyes
-Blind cave fish which has no eyes and no color
-Kauai Cave Wolf Spider which also has no eyes.
Bats are not true troglobites because they only use the cave for sleep, hiding and reproduction. There is about 50 000 troglobites in the world.
A bats habitat and niche would be inside of a cave, in the Twilight zone. The twilight zone is located in the middle of the cave, where some sunlight reaches. Because the bats aren’t so far back in the cave they would be able to leave the cave easy at night, in order to catch their prey, but aren’t so close to the front that they can’t sleep during the day because of the sunlight.
One way for food to get into the cave is through natural weather events such as a flood. Excess rainwater washes leaves, twigs, plants, etc. into a cave. This brings in food for insects and other animals. Another way food enters a cave is simply through animals, they bring it in. If times get hard in the cave, the organisms living in it can feed on each other. An example would be listed below which is how some centipedes grow large enough to feed on bats. Another source of food is guano.

Write the following Arithmetic Sequence using a Recursive Formula: an = -5 + 2(n – 1)
Given:
[tex]a_n=-5+2(n-1)[/tex]
To find:
The arithmetic sequence using a Recursive Formula.
Solution:
We have,
[tex]a_n=-5+2(n-1)[/tex] ...(i)
The explicit formula of an AP is
[tex]a_n=a_1+(n-1)d[/tex] ...(ii)
where, a₁ is first term and d is common difference.
From (i) and (ii), we get
[tex]a_1=-5,d=2[/tex]
Now, the recursive formula of an AP is
[tex]a_n=a_{n-1}+d[/tex]
Putting d=2, we get
[tex]a_n=a_{n-1}+2[/tex]
Therefore, the arithmetic sequence using a Recursive Formula is defined as [tex]a_n=a_{n-1}+2[/tex], where n>2 and [tex]a_1=-5[/tex].
Find the difference.
-7 - (-2) =
-7-(-2)
=> -7+2
=> -5
Hope it helps!
Answer: -5
Step-by-step explanation: In order to answer this question you need to remember that subtracting a negative is like adding a positive. So whenever you see something like -7 - (-2) its the same thing as -7 + 2. Just replace the two negative signs with a positive one.
Tabitha started working at a coffee shop making $8.75 per hour. Every 6 months, she gets a $0.40 cents raise.
a. Write a formula to represent her hourly wage after each raise.
b. Find her hourly wage at 3yrs.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Tabitha started working at a coffee shop making $8.75 per hour and that every 6 months, she gets a $0.40 cents raise.
a. The formula to represent her hourly wage after each raise would be:
= $8.75 + 0.40m
where m = period of 6 months
b. Find her hourly wage at 3yrs.
First we should note that 3 years = 3 × 12 = 36 months. Therefore, we would have 6 periods in 36 months since there's an increase every 6 months.
Therefore, using the formula
= $8.75 + 0.40m
where m = 6
= $8.75 + 0.40(6)
= $8.75 + $2.40
= $11.15
Write 2x + y = 17 in slope-intercept form.
Step-by-step explanation:
Slope / gradient of a line is obtained by making an equation in the form of:
y=mx+c
where ' m ' gives the slope/gradient of the line and ' c ' gives y-intercept.
2x+y=17
y = −2x+17
Here comparing this with y=mx+c gives:
m = -2 (slope/gradient) and
c = 17 (y-intercept)
So slope / gradient of line :
m=−2
