Answer:
200
Step-by-step explanation:
Remember PEMDAS
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75. 87+75+9
Add all of them up. 171
The answer is 171!
The coordinates of the midpoint of the segment whose endpoints are W (-3,-7) and X (-8,4) will be (-11/2, -3/2). Then the correct option is D.
The complete options are given below.
1. (-11/2) -(11/2)
2.(-5/2)-(3/2)
3.(-5/2-(11/2)
4. (-11/2) -(-3/2)
<h3>What is the midpoint of line segment AB?</h3>
Let C be the mid-point of the line segment AB.
A = (x₁, y₁)
B = (x₂, y₂)
C = (x, y)
Then the midpoint will be
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
The end points are given below.
(-3, -7) and (-8, 4)
We have
(x₁, y₁) = (-3, -7)
(x₂, y₂) = (-8, 4)
Then the mid-point will be
x = (- 3 - 8) / 2
x = -11 / 2
y = (-7 + 4) / 2
y = -3/2
Then the coordinates of the midpoint of the segment whose endpoints are W (-3,-7) and X (-8,4) will be (-11/2, -3/2).
Then the correct option is D.

Answer:
<h3>
x = -4</h3>
Step-by-step explanation:
vertical line is parallel to y-axis so its equation is always x = x₀
at any given point we have coordinates: (x₀, y₀)
given point (-4, 7) means x₀ = -4
so the equation of a vertical line passing through the point (-4, 7) is x=-4
He got 22/25 questions right because
if you put X as the number of questions he got right out of 25 and equal it to 88 out of 100 you can cross multiply to get X
x/25=88/100
100x=25×88
25×88=2200
100x=2200
divide 100 on both sides
therefore
2200/100= 22
hope this helps
