We can do this by factoring: x^2 + 5x - 36, which is (x+9)(x-4)
We plug f(x) as 0, so (x+9)(x-4)=0, so x = -9 and x = 4
The x-intercepts are (-9, 0) and (4, 0).

Answer:
The value of x is (-4) and y is (-5)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To Find</u>;</h3>
Now,
-6x = 24
-6x/(-6) = 24/(-6)
x = -4
So, Substitute the value of x in x – 5y = 21
x – 5y = 21
-4 – 5y = 21
-4 + 4 – 5y = 21 + 4
-5y = 25/
-5y/(-5) = 25/(-5)
y = -5
Thus, The value of x is (-4) and y is (-5)
<h3>
<u>For </u><u>Verification</u>;</h3>
x – 5y = 21
-4 – 5(-5) = 21
-4 + 25 = 21
21 = 21
-6x = 24
-6(-4) = 24
24 = 24
L.H.S = R.H.S
Hence Verified!

Your answer would be 9^13
|x+y| = |-8+(-13)| = |-8-13| = |-21| = 21
x ,y are the numbers
x = 5y-3
x+y = 27
substitute first equation into the second
(5y-3) +y =27
combine like terms
6y-3=27
add 3 to each side
6y=30
divide by 6
y=5
x = 5y-3
x=5*5-3
x=22
the two numbers are 22 and 5
