We can find the acceleration via
We have
Then by definition of average acceleration,
so that
We alternatively could have found the time without knowing the acceleration. Since acceleration is constant, the average velocity is
Then
Answer:
17
Step-by-step explanation:
because of the kind of angle it is, the two equations are equal. So, put the equations equal to each other and solve:
x+35=3x+1
combine like terms (by subtracting)
2x=34
isolate x by dividing by 2
x=17

Answer:
The costs of the plan are $0.15 per minute and a monthly fee of $39
Step-by-step explanation:
Let
x ----> the number of minutes used
y ----> is the total cost
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to
we have the ordered pairs
(100,54) and (660, 138)
substitute
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Convert to slope intercept form
Isolate the variable y
therefore
The costs of the plan are $0.15 per minute and a monthly fee of $39
