Step-by-step explanation:
Given [Missing details]
Spencer's expenses
Required:
An estimate for the amount spent on clothing
To do this, simply multiply the clothing percentage by the total amount.
Approximate
-2x - 4y = 1
<u>12y</u> = <u>-6x - 3</u>
12 12
y = -0.5x - 0.25
-2x - 4(-0.5x - 0.25) = 1
-2x + 2x + 1 = 1
0x + 1 = 1
<u> - 1 - 1</u>
<u>0x</u> = <u>0</u>
0 0
x = 0
-2(0) - 4y = 1
0 - 4y = 1
<u>-4y</u> = <u>1</u>
-4 -4
y = -0.25
(x, y) = (0,-0.25)
Answer:
Yes
Step-by-step explanation:
To see is (-1, -1) is a solution to the system, we can plug it into the system to check:
-1 = -8(-1)-9
-1 = 8-9
-1 = -1
-1 = -5(-1)-6
-1 = 5-6
-1 = -1
Both of the equations are true, therefore (-1, -1) is a solution to the system.
