Look at this system of linear equations. 12x + 3y = -4
y = 2x+4
What is the solution to the system of linear equations?
x = -2, y = 0
x = -1, y = 2
x = 4, y = -4
x = 2, y = 8

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

yes

\

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
