Answer:
f(-4) = 5
Step-by-step explanation:
Explanation of
_
| 5, x < -3
f(x) | 2x² - 4, -3 ≤ x ≤ 4
| 1 - 6x , x > 4
_
When the x in f(x) is less than -3 than f(x) = 5
When the x in f(x) is greater than -3 but less than 4 then f(x) = 2x² - 4
When the x in f(x) is greater than 4 than f(x) = 1 - 6x
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Now that we know this lets look back at the question.
We want to find f(-4).
Looking at the piece wise function we see that f(-4) follow x < -3 as "x" or -4 is less than -3. When x is less than -3, f(x) = 5, hence f(-4) = 5
Answer: 42
Step-by-step explanation:
First you have to subtract 450 from 6750 to get 6300
Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450
Third you have to do 6300 / 42 to get 150 so if you times 150x 42 equals 6300.
D -8\4
When you simplify the fraction
it becomes 2
The slope is

and the y intercept is -1
so the equation is y =

x-1
Answer:
46
Step-by-step explanation:
x +3x+5x - 54 = 360
x +3x+5x = 360 + 54
9x = 414
x= 46
