Answer:
y=-2,500x+19,000
Step-by-step explanation:
To write the equation, use y=mx+b. Look at the graph and identify m and b. b is the y-intercept and where the line crosses on the y-axis. Here it is 19,000.
To find the slope m, count the units from one point to another on the line. Identify the points on the line that go through grid line intersections. Count up/down then count right to form the ratio.
From point (0,19,000) to (2, 14,000). These points are -5,000 vertically and 2 horizontally. It forms the ratio -5,000/2 = -2,500. This is m.
So y=-2,500x+19,000
Answer:
f(x) = √x - 2
Step-by-step explanation:
that graph is what the graph of a square root looks like translated 2 units down
since the translation is vertical, the -2 must be outside the square root
Answer:
The answer is D
Step-by-step explanation:
Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)

Find the percentage of the salary she wants to take home
------------------------------------------------------------------------------------------
100% - 20% = 80%
---------------------------------------------
Information
---------------------------------------------
She wants to take home $32000
She wants to take home 80%
---------------------------------------------
Equate 80% to $32000 and find 100%
---------------------------------------------
80% = $32 000
1% = $32 000 ÷ 80
1% = $400
100% = $40 x 100
100% = $40 000
---------------------------------------------
Answer: Her salary has to be at least $40000
