First, find out c
4c=-12, so c=-3
-5c=d, so d=15
It would be Z-9 since you are subtracting 9 from Z
Answer:
x=1
18 = 6x+12= 1 :^
Step-by-step explanation:
Y=Mx+b
Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)
Slope is -1/2
Yint = -8
So the equation is y=(-1/2)x - 8
Step-by-step explanation:
to find height :
draw a height from A to CD
height = (13) 2 - 5) 2 = 12 Cm
area = 10+20 /2 X 12= 180 cm 2
