Hi
We need to solve 3x-7=2 for x
Let's start by adding 7 to both sides
3x-7+7=2+7
3x=9
Now just divide both sides by 3 so we can find the value for x
3x/3=9/3
x=3
Now substitute 3 for x in 4x-y=5 so we can find the value for y
4x-7=5
4(3)-y=5
-y+12=5
Add -12
-y+12-12=5-12
-y=-7
Now divide both sides by -1 so we can find the positive value for y
-y/-1=-7/-1
y=7
The answer is A
(3,7)
Good luck:0
Answer:
19/9
Step-by-step explanation:
x=2.1 repeating
10x=21.1 repeating
subtract x from 10x and you get 9x=19
divide by 9 on both sides of the equal sign to get x=19/9
Answer:
The coordinates for the reflection of quadrilateral ABCD is..
A'(-7,2) ----> A'(-7,-2)
B'(-7,4) ----> B'(-7,-4)
C'(-4,6) ----> C'(-4,-6)
D'(-1,6) ----> D'(-1,-6)
Step-by-step explanation:
Since it's being reflected over the x-axis, the x remains the same and the y becomes a negative.
Answer:
The net pay of is janet's $695 .
Step-by-step explanation:
As given
janet's gross pay is $750.
From gross pay $31 is deducted for oasdi, $10 for medicare, and $14 for income tax.
Thus
Net pay = gross pay - deducted for oasdi - deducted for medicare - deducted for income tax .
Put the value in the above
Net pay = 750 - 31 - 10 - 14
Net pay = 750 - 55
Net pay = $695
Therefore the net pay is $695 .
Answer:
Step-by-step explanation:
Using the distance formula, and (-3, -3) as (x1, y1) and (-6, 1) as (x2, y2), we obtain sqrt(9+16) = sqrt(25) = 5.
So, the distance between the two points is 5 units.
Answer:
$525
Step-by-step explanation:
Edgar Anderson earns in a week = $300
He also earns commission on the sales he makes after his first $1,000 = 15%
Mr. Anderson's sales for one week are = $2,500
His commission is on his sale = 2,500 - 1,000 = 1,500
He earns commission = 15% of 1,500
= 0.15 × 1,500
= $225
His gross pay for that week = $225 + $300 = $525
Mr. Anderson's gross pay for that week is $525.
