Answer:
y = (-1/4)*x+2
Step-by-step explanation:
The equation is written this way : y= mx+c
- m is the slope and c is a constant
- m = (f(4)-f(-4))/(4-(-4))= (1-3)/8 = -1/4
- y = (-1/4)*x + c
- replace x and y by the coordinates of a point to get c
- 1 = -1/4*4+c
- 1= -1+c
- c= 2
y = -1/4*x+2
Answer:
GH = 15
Step-by-step explanation:
In a trapezoid, the length of the median is one-half the sum of the lengths of the bases. Therefore:





10 because 25 goes into 100 4 times 40 divided by 4=10
Answer:
y = {1,2}
Step-by-step explanation:
5y^2 - 4y - 9 = y + 1
5y^2 - 5y - 10 = 0
5(y^2 - y - 2) = 0
5 (y - 2) (y - 1) = 0
y = {1,2}
