Step-by-step explanation:
the answers is 90. because 75.8
(0,-8)
Explanation: In y=mx + b, m represents the slope of the line and b represents the y intercept, since b is -8, it will cross the y-axis at (0,-8)
Answer:
vertex form automatically gives you your vertex and your y intercept so all you need to do is graph. Hope this helps
Step-by-step explanation:
Step-by-step explanation:
The snowplow's speed is 40 mph minus the loss from the snow, which is 1.2 mph times the depth of snow in inches.
y = 40 − 1.2x
When y = 0:
0 = 40 − 1.2x
1.2x = 40
x = 33 ⅓
The snowplow stops moving when the snow is 33 ⅓ inches deep or more.
