Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
Hope this helps!
Answer: I’m pretty sure it’s C(x)=0.75(x-5) since it’s the same formula as the question
Step-by-step explanation:
Answer:
y = 5/4 x
Step-by-step explanation:
We already know the slope, so now we need to find the y-intercept. To do that, you need to simply plug the coordinates into the equation which is
y = 5/4 x + b
-5 = 5/4 (-4) + b
-5 = -5 + b
0 = b
y = 5/4 x + 0 or simply just y = 5/4 x.
