Angel is saving all of his money for a ticket to Grad Bash. Before he started working, he had $7.50 in his bank account On Satur

Serggg [28]

Answer:

The second choice is correct. (f(x) = 8.50x+7.50)

Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50 dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.

Let me know if this helps!

What is the equation of the line shown below?

miskamm [114]

Answer:

y= 1x - 1

Step-by-step explanation:

Slope-intercept form: y=mx + b

(-4,-5) (5,4)

m= (y2 - y1)/(x2 - x1) = (4+5)/(5+4)=1

4=1(5)+b

4=5 + b 4-5=b b= -1

y= 1x - 1

the graph of f(x) can be compressed vertically and shifted to the left to produce the graph of g(x). if f(x)=x^3 which of the fo

Paul [167]

Answer:

Example: g(x) = 0.5(x+2)^3

Step-by-step explanation:

The correct answer choice should match the following:

A vertical compression means x^3 is multiplied by a number less than 1. Look for a fraction or decimal less than 1 as the leading coefficient.
A shift to the left it produced by adding values inside the operation to the input. Look for (x+2)^3 or (x+12)^3.

A. Use substitution and show work

Alja [10]

A) 2x -3(3x -7) = 7 . . . . substitute for y
.. -7x = -14 . . . . . . . . . . . subtract 21
.. x = 2 . . . . . . . . . . . . . divide by -7
.. y = 3*2 -7 = -1 . . . . . . substitute for x
(x, y) = (2, -1)

B) 5(5x -2y) -2(3x -5y) = 5(8) -2(1) . . . . subtract 2 times 2nd equation from 5 times 1st
.. 19x = 38 . . . . simplify
.. x = 2 . . . . . . . divide by 19
.. y = (5x -8)/2 = 1 . . . . solve 1st equation for y, substitute x
(x, y) = (2, 1)

C) See the first graph.
(x, y) = (-4, 1)

D) See the second graph.
(x, y) = (3, 2)
