I think the answer is -2/1x-3
The solution to the given system of equation is (7,-3).
<h3>What is the solution to the given system of equation?</h3>
Given the equations in the question;
2x + 7y = -7 ----- equ 1
-4x - 3y = - 19 ---- equ 2
First, we solve for x in equation 1
2x = -7y - 7
x = -7y/2 - 7/2
Next, replace all occurrence of x with -7y/2 - 7/2 in equation 2
-4x - 3y = - 19
-4(-7y/2 - 7/2) - 3y = - 19
14y + 14 - 3y = -19
14y - 3y = -19 - 14
11y = -33
y = -33/11
y = -3
Plug y = -3 into equation 1 and solve for x
2x + 7y = -7
2x + 7(-3) = -7
2x - 21 = -7
2x = -7 + 21
2x = 14
x = 14/2
x = 7
Therefore, the solution to the given system of equation is (7,-3).

Answer:
\left(x+3\right)\left(x-9\right)
Step-by-step explanation:
Answer:
To find the percent of a number, you just need to convert the percent into a decimal (move the decimal over to the right 2 places) and multiply by 24 hours.
Sleep: 0.40 x 24 = 9.6 hours
School: 0.25 x 24 = 6 hours
Homework: 0.10 x 24 = 2.4 hours
Free Time: 0.15 x 24 = 3.6 hours
Eating: 0.10 x 24 = 2.4 hours
Hope this helps!
