For 50 points

use a graphing calculator to find the value of f(x) when x = −1 for the function
f(x) = −4x − 5/2 .
enter your answer as a decimal if needed.
f(−1) =

1.5 or 1 1/5

Just plug -1 into the equation as x:

-4 x -1 - 5/2

4 - 5/2

1.5

Why did you mark as college level maths tho. This is more like middle school

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
