Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12
Answer:
Step-by-step explanation:
Let Terri spent the 'x' hours in the river,
Per hour rental charged by Timmy's Tubes =
=
= $7.5
Charges for 'x' hours = $7.5x
Therefore, function that defines the rental of Timmy's tube will be,
f(x) = 7.5x
Another company Fred's float charges a base fee $2 plus $6.25 per hours.
For 'x' hours Fred's float will charge = 6.25x + 2
And the function that defines the charges will be,
g(x) = 6.25x + 2
1). If x = 1.5 hours,
Rental charged by Timmy's tube,
f(1.5) = 7.5(1.5)
= $11.25
Rental charged by Fred's float,
g(1.5) = 6.25(1.5) + 2
= $11.375
2). If Terri has $12 to spend,
For f(x) = 12,
12 = 7.5x
x = 1.6 hours
For g(x) = 12
12 = 6.25x + 2
10 = 6.25x
x = 1.6 hours
Therefore, both the companies charge the same for 1.6 hors.
Terri can opt any company to spend $12.
Answer:
48
Step-by-step explanation:
You can easily find the percent of a number by multiplying the percent in decimal format (0.32) by the number you want to find the percent of.
150 * 0.32 = 48
