Answer:
-3/5
Step-by-step explanation:
10-8/4-12=-0.6=-3/5
Answer:
We need to find the value of b to make 8b - 27 be equal to 5, so:
8b - 27 = 5
We solve the equation:
8b = 5 + 27
8b = 32
We divide both sides by 8:
b = 32/8 = 4
So now, we know that b=4, and we can verify:
8*4 - 27 = 5
32 - 27 = 5 TRUE
Answer:
5km costs $4
if you take the intial charge of $2, you're paying $4 per 5km
hence 10km= 2 *5km= 2*$4=$8+initial charge $2= $10
15Km= 3*5km= 3*$4= $12 + intial charge $2 = $14
Step-by-step explanation:
Y = mx
We just need to find the slope:
y2 - y1 / x2 -x1 = -4 - 4 / 1 - - 1 = -8/2 = -4/1 = -4
so: y = -4x
Hope that helps! :)
