Answer:

a= -12 and b=36

Step-by-step explanation:

a+b=24 and 3a+b

a-3a+b=24

-2a+b-b=24

-2a/-2=24/-2

a= -12

then substitute the value of a in a+b=24 to get the value of b

so let see -12+b=24

b=24+12

b=36

we can check it by the equation -2a+b-b=24

-2(-12)+36-36=24

24=24 so as you have seen the answer is correct

thanks!!!

The graph of y=x^2 was transformed to Y= -(x+3)^2 +5. Describe all transformations applied to the original function and determin

mina [271]

Hey there!

1. The graph was flipped vertically and now opens downward.

We know this because there is a negative sign in front of the equation:

$y=$ $\boxed-$ $(x+3)^2+5$

2. The graph was moved 3 units to the left.

We know this because there is 3 added to x inside of the parenthesis. Remember, inside (parenthesis) is opposite and acts on x, outside (parenthesis) is same and acts on y.

$y=-(x\boxed{+3})^2+5$

3. The graph was moved 5 units up.

We know this because there is 5 added at the end of the equation. It acts on y because it is outside of the parenthesis.

$y=-(x+3)^2\boxed{+5}$

Hope this helps!
