Answer:

f(1)=-3

f(-4)=-11

f(6)=0

Step-by-step explanation:

Use the correct formula depending on what (x) equals.

When (x=1) you use the second formula because 1 is greater than -2 but less than 4

When (x=-4) you use the first formula because -4 is less than -2

When (x=6) you use the third formula because 6 is greater than 4

Do you think any ordered pairs are solutions to BOTH y=x+5 and y=-2x-1? Explain.
Rina8888 [55]

Answer:

ordered pair(-2 , 3) is the solution

Step-by-step explanation:

y=x+5

y=-2x-1

x+5 = -2x-1    substitution

x+5+2x-5 = -2x-1+2x-5

3x = -6

x = -2

y = -2+5 = 3

ordered pair(-2 , 3) is the solution

Simplify the difference. (–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x)
sineoko [7]

Answer: 2x^4+2x+10

Step-by-step explanation:

You need to remember the mulplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-

Knowing this, you can distributive the negative sign. Then you get:

(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x

Now you need to add the like terms. Then:

=2x+2x^4+10

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

=2x^4+2x+10
