\huge\underline\bold\blue{ƛƝƧƜЄƦ}

\large\boxed{f(x)=-129}

Step-by-step explanation:

Given - f(x) = 21

Now we have to put the value in the given equation

f(x) = -6x-3

f(21) = -6(21) -3

= - 126 -3

= -129

Hope it helps

Answer:

\huge \boxed{x=-4}

Step-by-step explanation:

\sf f(x)=-6x-3 \\\\\\ f(x)=21

Applying substitution method and solving for the value of x.

\sf 21=-6x-3

Adding 3 to both sides.

\sf 24=-6x

Dividing both sides by -6.

\sf -4=x

This is some bull help
slamgirl [31]

To find y you need to insert x into the equation. The equation is y=2x+2, so insert the x on the table to find the y.

y=2(-4)+2=-6

y=2(-2)+2=-2

y=2(0)+2=2

y=2(1)+2=4

y=2(3)+2=8

These follow the equation's rule so it is correct.

Two plot the values of x and y you need to put it in (x,y) then plot it. Then you can check it by using the equation, y=mx+b, the b is the y intercept, so check to see if it starts there, and then check and see if it followings the slope

(-4, -6), (-2, -2), (0, 2), (1, 4), (3, 8)

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
