Answer:

Option 1

Step-by-step explanation:

You can tell if a function is even if f(-x)=f(x):

f(x)=x^2-x+8

f(-x)=(-x)^2-(-x)+8

f(-x)=x^2+x+8

Since f(-x)\neq f(x), the function is not even. Therefore, option 1 is the best option.

Find the value of d and YZ if Y is between X and Z.
docker41 [41]

Y is between X and Z

The value of d=2 and the value of YZ = 16

Given :

Y is between X and Z.

XY = 11d, YZ = 9d – 2, XZ = 5d + 28

We need to find the value of d

we know that Y is between X  and Z

So, XZ=XY+YZ

Replace the given expression and solve for d

XZ=XY+YZ\\5d+28=11d+9d-2\\Combine \; like \; terms\\5d+28=20d-2\\Subtract \; 5d\\28=15d-2\\\\Add \; 2\\30=15d\\Divide \; by \; 15\\d=2

The value of d=2

Now we find out YZ using d=2

YZ=9d-2\\YZ=9(2)-2\\YZ=16

The value of YZ is 16
