Is x - 8 a factor of the function f(x) = -2x3 + 17x2 - 64? Explain.
Oduvanchick [21]

we know that

If (x-8) is a factor of the function f(x)=-2x^{3}+17x^{2}-64

then

x=8 is a root of the function f(x)

therefore

For x=8 the value of the function must be zero

Verify

Substitute the value of x=8 in the function

f(8)=-2(8)^{3}+17(8)^{2}-64

f(8)=-2(512)+17(64)-64

f(8)=-1,024+1,088-64

f(8)=-1,088+1,088

f(8)=0

therefore

<u>the answer is</u>

Yes, (x-8) is a factor of the function f(x)

Y = 3x - 8<br>y = 4 - X​
mihalych1998 [28]

Answer:

Step-by-step explanation:

Using substitution method.

y = 3x - 8  -------(i)

y = 4 - x -------- (ii)

Substitute y = 3x-8 in equation (ii)

3x -  8= 4 - x                      {Add x to both sides}

3x - 8 + x = 4 - x +x

4x - 8 = 4         {Add 8 to both sides}

4x = 4 + 8

4x = 12    {Divide both sides by 4}

x = 12/4

x = 3

Substitute x = 3 in Equation (i)

y = 3*3 - 8

y = 9 - 8

y = 1
