c in step 4 comes from step 3... 49+36

Need help in algebra fast
Gennadij [26K]

Answer:

A

Step-by-step explanation:

This is a strict inequality so the line must be dotted, meaning it can only be A or D.

The inequality says that y is less than -2x+4 so we want the region under the line, making A the correct answer.

Describe the behavior of the graph at the x-intercepts for the function f(x)=(2x-7)^7(x+3)^4. Identify each x-intercept and just
Shkiper50 [21]

Answer:

f(x)=(2x-7)^7(x+3)^4

When y=0, (2x-7)^7=0 and x=3.5 OR

(x+3)^4=0, and x=-3

Look at x=h or f(2)

That is 96-56-44+2 and it is not equal to 0. (x-2) is not a factor.

x^3-5x^2+6x-30

after trying 1,2, and 3, I tried 5

5/1===-5===6===-30

==1===0====6====30

(x^2-6) with no remainder

the factors are (x-5)(x^2+6)

the zeroes are 5, +/- i sqrt (6). Only one real 0.

hope this helps let me know in the comments if i'm wrong
