Answer:
Using substitution method
First make y in equation 1 the subject of formula
Y=4x-2
Sub in equation 2
2(4x-2)-8x=4
8x-4-8=4
8x=4+12
8x=16
X=2
Sub in any of equation to get y
Step-by-step explanation:
Y =4(2)-2=6
20 - 6.57
The change will be $13.43
-Whenever making change, start at what the total is and count in coins and dollars until you reach the given amount of money
As you can tell, the next time decreases by three every time. So, the tenth term would be -29.
-2,-5,-8,-11,-14,-17,-20,-23,-26,-29
Answer:
Step-by-step explanation:
<u>Given vertices WXYZ:</u>
- W(-4,5), X(2,4), Y(3, -4), Z(-1, -6)
Perimeter is the sum of the side length.
<u>Use distance formula to find each side:</u>
- WX = ≈ 6.08
- XY = ≈ 8.06
- YZ = ≈ 4.47
- WZ = ≈ 11.40
<u>Find perimeter:</u>
- P = 6.08 + 8.06 + 4.47 + 11.40 = 30.01 units
Answer:
x = -4, -2
Step-by-step explanation:
-x² - 6x - 8 = 0
x² + 6x + 8 = 0
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) = 0
(x + 4)(x + 2) = 0
x = -4, -2
