Find the slope and Y intercept from the equation 12x+3y=6
Answer:
slope = -4 y-intercept = (0, 2)
Step-by-step explanation:
12x + 3y = 6
-12x -12x
-----------------------------------------------
3y = -12x + 6
3y/3 = -12x/3 + 6/3
-----------------------------------------------
y = -4x + 2 ( this is in y = mx + b form, m representing the solpe and b representing the y-intercept)
This being said, the slope = -4 and the y-intercept = (0, 2).

Answer:
Use Close Call to practice two-digit addition or subtraction. The best math card games are simple at heart. To play Close Call, each player deals themselves four cards then determines how to arrange them so they make two two-digit numbers that add up as close as possible to 100 without going over.

A lab scale weighs 3 pounds, 5 ounces. Which of the following is the scale weight in (oz)?
a. 35 oz
b. 53oz
c. 41
d. 29oz
Answer:
53 ounces
Step-by-step explanation:
We know that,
1 pound = 16 ounce
3 pounds = 48 ounces
We need to find the weight in 3 pounds, 5 ounces.
3 pounds, 5 ounces = 48 ounces+ 5 ounce
= 53 ounces
So, the scale weight is 53 ounces. Hence, the correct option is (b).

When a numerator equals zero, a ratio is what?
Answer:
A numerator is allowed to take on the value of zero in a fraction. Any legal fraction (denominator not equal to zero) with a numerator equal to zero has an overall value of zero. all have a fraction value of zero because the numerators are equal to zero.

Answer:
x= 8/9
Step-by-step explanation:
Open everything up to get 5x+2x-6=-2x+2. Move numbers with an x to the left side and without to the right to have 5x+2x+2x=2+6. Simplify to have 9x=8. Divide by 9 which leaves you with x= 8/9

Step-by-step explanation:
A value is excluded when it makes the rational expression undefined. (such as making the denominator 0, etc.)
For example when x = 8, (x - 8) at the denominator will become 0 and make it undefined.
The correct options are the 3rd and 4th ones.
The average person that weighs 150 pounds has approximately 4.5 liters of blood in their body. Based on that same scale, supposedly how many liters of blood would a 250 pound person have?
Answer:
First you find how many pounds for 1 litre of blood. Trick is if you divide x by y, the answer you get will follow the unit of x. So if you divide 150 pounds by 4.5 litres, the answer will be 33.33 pounds per litre. So how many 33.33... is there in 250? Just divide 250 by 33.333 or (150/4.5), you'd get 7.5. That means for there's 7.5 parts of 33.333 pounds in 250 pounds. And if 33.333 pounds is equal to 1 litre of blood, you get 7.5 liter!

Answer:
Option B
Step-by-step explanation:
Don't trust answers teachers don't bother to spell correctly. Plus, finding the 100th term is very easy.
However, the explicit formula will take a long time to use, because it's explicit.
Option C is just wrong. You're supposed to multiply in the recursive formula.
Option D might be correct, but never trust those answers. Teachers do that to trip you up

What are some of the more significant limitations of mathematical models as imitators/predictors of natural phenomena
Answer:
See explanation
Step-by-step explanation:
A mathematical model refers to a mathematical function that describes natural phenomena.
Models are used to approximate natural phenomena hence they are not really exact representations of reality. Thus mathematical models are inherently imperfect and so is our understanding of natural phenomena represented by these mathematical models.
The mathematical parameters used in models to represent real processes are uncertain since they are determined from experiment or represent more than one process.
Lastly, the initial and the boundary conditions in a model may not be explicitly established.
Define the opposite and the absolute value of -15.

Question on the picture:)
Answer:
a. No
b. Yes
Step-by-step explanation:
a.
x - 4 = 12
x - 4 + 4 = 12 + 4
x = 16
16 ≠ 8
Therefore, the following value given for problem a is not a solution to the given equation.
b. (3 + x)/4 = 3
(3 + x)/4 * 4 = 3 * 4
3 + x = 12
3 + x - 3 = 12 - 3
x = 9
9 = 9
Therefore, the following value given for problem b is a solution to the given equation.
Triangle XYZ is reflected across the x-axis, and X = (–11, 8). What are the coordinates of X’ ?
Here are your choices:
A) (11,–8)
A) (–8, 11)
A) (11, 8)
A) (–11, –8)
I hope this question isn't confusing you guys∪ω∪
9514 1404 393
Answer:
(-11, -8)
Step-by-step explanation:
Reflection across the x-axis changes the sign of the y-coordinate.
For X(-11, 8), the reflected point is X'(-11, -8). (matches the last choice)

Find the value of the x in the equation 4(6x-9.5)=46
Answer:
3.5
Step-by-step explanation:
First you distribute. 24x-38=46.
Then add 38 to both sides
24x=84
Then divide both sides by 24
x=3.5
Answer:
x= 3.5
Step-by-step explanation:
[tex]4(6x-9.5)=46\\24x-38=46\\ +38 +38\\\\frac{24x}{24} = \frac{84}{24} \\ x=3.5[/tex]Sue walked 3.38 miles. Alex walked five times as many miles as Sue. Dan walked 4.68 miles more than Alex. How far did Dan walk
Answer:
21.58 miles
Step-by-step explanation:
First let's find how many miles Alex walked.
It said "Alex walked five times as many miles as Sue" so lets multiply 3.38 with 5: 3.38 x 5 = 16.9
So, Alex walked 16.9 miles. Now we can find Dan's.
It said "Dan walked 4.68 miles more than Alex" so lets add 4.68 to 16.9: 16.9 + 4.68 = 21.58
So Dan walked 21.58 miles
