Answer:
A. y = -2x - 3
Step-by-step explanation:
y-5= -2(x + 4)
Expand the brackets.
y - 5 = -2x - 8
Add 5 to both sides.
y = -2x - 8 + 5
y = -2x - 3
Make the coefficient of y the same in both equations:
To do this, multiply equation one by 2, and equation two by 5 (this will make the coefficient 10 in both).
14x + 10y = 38
-35x - 10y = -80
Eliminate the y variable by adding the equations from each other
(14x + 10y = 38)
+ (-35x - 10y = -80)
= -21x + 0y = -42
We now have -21x = -42. The y variable has been eliminated.
Solve for x
-21x = -42
Divide both sides by -21 to get x on its own.
x = 2
Substitute x into the equation to find y.
7*2+5y=19
14+5y=19
Subtract 14 from both sides.
5y=19-14
5y=5
Divide by 5 on both sides to get y on its own.
y=5/5
y=1
The answer is (2,1)

Answer: </h2><h2>
Mohammed's net pay each week is $298.90 (61%).</h2>
Step-by-step explanation:
- 15% + 8% + 9% + 7% = 39%
- 39% - 100% = 61%
- $490 x 61% = $298.90
<h2> </h2>
<h2> <u><em>
The answer is 61%.</em></u></h2><h3><u><em>
The exact cash amount is $298.90 </em></u></h3>
Answer:
1400
Step-by-step explanation:
67 rounds to 70 because 7 is bigger than 5 so it rounds up. 23 rounds down since 3 is smaller than 5.
So, 70x20=1400
