<u>Answer:</u>
<u>Step-by-step explanation:</u>
-4x - 9y = -25
7(-4x - 9y = -25)
-28x - 63y = -175
<u>Now, let's substitute the value of y into the first equation.</u>
- => -7x - 2y = 25
- => -7x - 2(5) = 25
- => -7x - 10 = 25
- => -7x = 35
- => x = -5
<u>Now, let's check our answer to make sure our answer is correct.</u>
<u>Check:</u>
- -4x - 9y = -25
- => -4(-5) - 9(5) = -25
- => 20 - 45 = -25
- => -25 = -25
Hence, this is proved correct.

Step-by-step explanation: this should help its not the answer but it's support
Given : g(x) = 
and h(x)=2x-8.
Let us find g*h(x) function now.
g*h(x) = g(x) * h(x) = 
Or g*h(x) =(2x-8).
He have square root(x-4) in composite function f*h(x).
So, we need to find the domain, we need to check for that values of x's, square root(x-4) would be defined.
Square roots are undefined for negative values.
Therefore, we can setup an inequality for it's domain x-4≥0.
Adding 4 on both sides, we get
x-4+4≥0+4.
x≥4.
Therefore, Domain is all values greater than or equal to 4.
But, restrictions would be all values less than 4 (because less than 4 would give a negative number inside square root).
Think of 6y as
y + y + y + y + y + y
Now subtract a y from that.
y + y + y + y + y + y - y = y + y + y + y + y = 5y
