Answer:
Distance between the points = 7 units
Step-by-step explanation:
If a point P(h, k) is reflected across x-axis, rule to be followed will be,
P(h, k) → P'(h, -k)
By this rule,
If the coordinates of new point P' are (5, -3.5)
Then the coordinates of pre-image point P will be (5, 3.5)
By using formula to get the distance between two points,
Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
Distance between (5, 3.5) and (5, -3.5) = [tex]\sqrt{(5-5)^2+(3.5+3.5)^2}[/tex]
= [tex]\sqrt{0+7^2}[/tex]
= 7 units

On a coordinate plane, triangle G H J has points (1, 1), (4, 1), (4, 5). What is the area of triangle GHJ? 5 square units 6 square units 7 square units 12 square units
Answer:
B: 6 units
Step-by-step explanation:
just took the test
The area of triangle GHJ is 6 square units.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the area of triangle GHJ, we can use the formula:
Area = (1/2) x base x height
where the base is any one of the sides of the triangle, and the height is the perpendicular distance from that side to the opposite vertex.
We can choose any side of the triangle as the base, but it is convenient to choose the side that is horizontal or vertical to simplify the calculations.
In this case,
We can choose the base to be the side GH, which has a length of 3 units (since the x-coordinates of G and H are different).
To find the height of the triangle,
We need to draw a perpendicular line from the vertex J to the base GH, and then calculate its length.
Since the x-coordinate of J is 4 and the x-coordinates of G and H are both 1, the base GH is 3 units long.
Also,
The y-coordinate of J is 5, and the y-coordinates of G and H are both 1, so the height of the triangle is 4 units.
The area of triangle GHJ is:
Area = (1/2) x base x height
Area = (1/2) x 3 x 4
Area = 6 square units
Thus,
The area of triangle GHJ is 6 square units.

On a map that bus stop is at the coordinates (5,4) and the pond is at the coordinates (8,5) what is the distance from the bus stop to the pond to the nearest unit
Answer:
Hence the distance is 3.16
Step-by-step explanation:
Given data
The bus stop is at the coordinates (5,4) and
x1=5
y1=4
The pond is at the coordinates (8,5)
x2=8
y2=5
The expression for the distance between two coordinates is
d=√((x_2-x_1)²+(y_2-y_1)²)
Substitute
d=√((8-5)²+(5-4)²)
d=√((3)²+(1)²)
d=√9+1
d=√10
d=3.16

Step-by-step explanation:
Here is the full question
Nicole is playing a video game where each round lasts 7/12 fraction of an hour. She has scheduled 3 3/4 fraction hours to play the game. How many rounds can Nicole play? rounds
Number of rounds she can play = total time she has scheduled / length of each round
length of each round = 7/12
total time she has scheduled = 3 3/4
3 3/4 ÷ 7/12
3 3/4 x 12/7
convert to the total time scheduled to an improper fraction
to convert to improper fraction, take the following steps :
Multiply the whole number (3) by the denominator (4) = 3x 4 = 12 Add the numerator to the answer gotten in the previous step = 14 + 3 = 15 divide the number gotten in the previous step by the denominator = 15/4[tex]\frac{15}{4}[/tex] × [tex]\frac{12}{7}[/tex] = [tex]\frac{45}{7}[/tex] rounds or [tex]6\frac{3}{7}[/tex] rounds

What is a radical expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
The radical sign, which may be read as either the nth root of x or x radical n, expresses the root of a number. The vinculum, or horizontal line that encircles the number, and the radicand, or number beneath it, are both technical terms.
The given expression is 49x¹⁸. The value of the expression will be solved as:-
E = √( 49x¹⁸)
E = √ (7² x x¹⁸ )
E = 7x⁹
Therefore, the square root will be equal to 7x⁹.

d) [tex](9*3/4)+y[/tex]
Step-by-step explanation:
b) [tex]9+y*(3/4)[/tex]
This expression is not equivalent, as the original expression, [tex]y+9*\frac{3}{4}[/tex] , has 9 multiplied to [tex]\frac{3}{4}[/tex] instead of y. You can interchange values like this when it comes to addition, but not multiplication.
c) [tex](y+9)(3/4)[/tex]
This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to [tex]\frac{3}{4}[/tex].
[tex](y+9)(3/4)\\= y(3/4)+9(3/4)[/tex]
d) [tex](9*3/4)+y[/tex]
This expression is equivalent, as 9 and [tex]\frac{3}{4}[/tex] are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:
[tex](9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}[/tex]

17
23
-17
-23
Answer:
-23
Step-by-step explanation:
We are given the functions;
h(x) = 5x - 3 and j(x) = -2x
Now, we want to find h[j(2)]
j(2) = -2(2)
j(2) = -4
Thus;
h(-4) = 5(-4) - 3
h(-4) = -20 - 3
h(-4) = - 23
3/7 of the students in a school are in sixth grade. How many students are in the school if 63 of them are sixth graders?
Answer:
There are 147 students in the school.
Step-by-step explanation:
3/7 of the students are in sixth grade, 63 students are in the sixth grade.
take 63 and divide it by the numerator, 3, you get 21.
You now multiply the fraction by 21 to get the full number of students in the school.
3 * 21 = 63, 7 * 21 = 147
So 63 sixth graders out of 147 total students in the school.
