Answer:
x = 10
y = 50
Step-by-step explanation:
9x - 70 = x + 10
8x - 70 = 10
8x = 80
x = 10
3y - 60 = 90
3y = 150
y = 50

To get the largest area, the length and the width have to be as close as possible, if not the same.
Given Perimeter = 176 unit.
Length = 176 ÷ 4 = 44 units
Area = Length x Width
Area = 44 x 44 = 1936 units²
1936 units² is the largest possible area, given that the perimeter is 176 units. The dimension being 44 by 44
Answer:
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.
Step-by-step explanation:
Part A:
y=mx+b
621=83(7)+b
Part B:
621=83(7)+b
621=581+b
621-581=b
b=40
