Shaun's savings can be modeled by the regression equation y = 6x^2 + 75x+200. Which of the following is the best prediction for

kipiarov [429]

Answer:

Option D

Step-by-step explanation:

The equation to predict the amount saved is

$y = 6x ^ 2 + 75x + 200.$

Assuming that the variable x represents the saving months, then substitute $x = 25$ in the quadratic equation and solve for y.

$y = 6 (25) ^ 2 +75 (25) +200\\\\y = \$\ 5,825$

The answer is the option D $5,825

What are the intercepts of the line 3x – 15y = 60? A. x-intercept: –4; y-intercept: 20 B. x-intercept: –3; y-intercept: 15

AnnZ [28]

X intercept is when y = 0
3x -15(0) = 60
3x = 60
x = 20

y intercept is when x=0
3(0) -15y = 60
-15y = 60
y = -4

You are hired to work at quickie-mart and will be paid $9.50 per hour 1. Write an income function that describes the amount of m

zzz [600]

Answer:

f(x)=nx

f(x)=9.50x

Step-by-step explanation:

Let x be the amount of hours and n be the hourly rate (9.50).

$f(x)=nx$

or if you prefer to use 9.50 instead of n, the function would be:

$f(x)=9.50x$
