Answer:
x = 22, y = -4
Step-by-step explanation:
x + 6y = -2 --- Equation 1
-x = 3y - 10 --- Equation 2
Equation 2 ×(-1): x = -3y + 10 --- Equation 3
Substitute x = -3y + 10 into Equation 1:
x + 6y = -2
-3y + 10 + 6y = -2
3y + 10 = -2
3y = -2-10
= -12
y = -12 ÷ 3
y = -4
Substitute y = -4 into Equation 3:
x = -3y + 10
x = -3(-4) + 10
= 12 + 10
x = 22
First order the numbers from least to greatest.
8,12,31, 45, 45,47, 48, 51,55
Min: 8
Q1: 21.5
Q2: 45
Q3: 49.5
Max: 55
To find Q1 find the average of the lower half. (12 + 31)/2
43/2 = 21.5
To find Q3 find the average of the upper half.
(48+51)/2= 49.5
880689 is the exact answer
Answer: y=-4x+7
Step-by-step explanation: Move 8x to the right side to isolate y. 2y=14-8x. Divide the whole equation by 2 to get y by itself. y=7-4x
