Answer:
Step-by-step explanation:
hello :
y-3=-2(x+5)
y - intercept when : x=0 : y-3 =-2(0+5)
y-3 =-10
y = - 7
Answer:
Step-by-step explanation:
for c it would be 1\8
for E it would be 3\8
Answer:
x = 20
y = 26
Step-by-step explanation:
40 and 2x are vertical angles, so they're equal to each other.
40 = 2x
Divide both sides by 2
x = 20
We see that 40 and 5y + 10 are a linear pair, which means they add up to 180.
5y + 10 + 40 = 180
5y + 50 = 180
5y = 130
y = 26
