1) x = 5
2x + 5 = 30 - 3x
(+ 3x)
5x + 5 = 30
(- 5)
5x = 25
( / 5)
x = 5

2) x = -2
(-4 * 11x) + (-4 * 2) = 80
-44x - 8 = 80
(+ 8)
-44x = 88
( / -44)
x = -2

3) x = 49
3x + 33 = 180
(- 33)
3x = 147
( / 3)
x = 49

I hope this helps! The / symbol means divide by the way :)

Answer:

Step-by-step explanation:

Calculation for Jennifer's monthly gross pay

First step is to calculate The total tax percentage deductions

Using this formula

Total tax percentage deductions =State tax + City tax + Social security + Medicare

Let plug in the formula

Total tax percentage deductions = 3.5% +2.5% +6.2% +1.45%

Total tax percentage deductions = 13.65%

Now let calculate the monthly gross pay

Monthly gross pay= ($3,981.22 +87)/(1-13.65%)

Monthly gross pay= ($3,981.22 +87)/0.8635

Monthly gross pay=$4,068.22/0.8635

Monthly gross pay= $4,711.31

Solve the following equation for y: 35x - 7y = 49, what is the slope?
agasfer [191]

Answer:

y = 5x - 7

slope = 5

Step-by-step explanation:

35x - 7y = 49

Subtract 35x from both sides.

-7y = -35x + 49

Divide both sides by -7.

y = 5x - 7

The equation is now in the slope-intercept form, y = mx + b, where m is the slope.

slope = m = 5

What is the domain of the relation?
Thepotemich [5.8K]

Answer: -4

Step-by-step explanation:

Domain: x-axis

Range: y-axis

The relation graph shows the points in which the domain is located. To find the Domain, go to the point in the x-axis (the horizontal line) and note the number where the point lies. For this question, the point on the left side of the graph lies on negative four (-4), and on the right side, the point is on 6. Therefore, the domain of this relation is negative four is greater than/equal to x is less than/equal to six. It could also be written like this: -4\leq x\leq 6.

Does the point (6,3) satisfy the equation y = 4(x – 5)?
Darina [25.2K]

Answer:

No

Step-by-step explanation:

plug (6,3) into the given equation to find out

3 = 4(6-5)

3 = 4(1)

3 = 4

since 3 does not equal 4, the point (6,3) does not satisfy the equation y=4(x-5)
