Answer:
a
Step-by-step explanation:
28/7=4
24/8=3
X=15. This is the Altitude theorem which is Altitude/Part = Altitude/Other part. In this question you would set up the proportion 9/X = X/25 and multiply cross products to get 225=X^2. Then you undo X^2 by doing the square route of 225 and then you get 15 as the final answer.
Answer:
The first question:
x = -1
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-x - 1 = -1 • (x + 1)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-1 = 0
Add 1 to both sides of the equation :
-x = 1
Multiply both sides of the equation by (-1) : x = -1
One solution was found :
x = -1

The correct answer is option C.$35.70
Answer:
y+2=1/2(x+1)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(3-(-1))
m=(0+2)/(3+1)
m=2/4
m=1/2
y-y1=m(x-x1)
y-(-2)=1/2(x-(-1))
y+2=1/2(x+1)
