WILL MARK BRAINLIEST! The multipliers of this system of equations have been determined to create opposite terms of the y-variable.

4 (one-fourth x minus three-fourths y = 34) right-arrow x minus 3 y = 136
24 (three-fourths x + one-eighth y = negative 12) right-arrow 18 x + 3 y = negative 288

thus, x=-34 and y=170/-3

Step-by-step explanation:

4((1/4)*x-(3/4)*y)=34

x-3y=136

24((3/4)*x+(1/8)*y)=12

18x+3y=-288

4x-3y=34⇒x-3y=136

18x+3y=12⇒18x+3y=-288

lets solve 4x-3y=34⇒x-3y=136 first:

4x-3y=34

x-3y=136

4x-3y=34    

-x+3y=-136

3x=-102

x=-102/3

x=-34

lets plug in x to one of the equations, since both equations are equal to each other:

4x-3y=34

4(-34)-3y=34

-136-3y=34

-3y=170

y=170/-3

now lets solve: 18x+3y=12⇒18x+3y=-288

18x+3y=12

18x+3y=-288

18x+3y=12

-18x-3y=288

0300

so, this system doesn't work

thus, x=-34 and y=170/-3

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
