<h2>Solving Equations</h2>

To solve linear equations, we must perform inverse operations on both sides of the equal sign to <em>cancel values out</em>.

If something is being added to x, subtract it from both sides.
If something is being subtracted from x, add it on both sides.
Same with multiplication and division. If x is being divided, multiply. If x is being multiplied, divide.

We perform inverse operations to<em> combine like terms</em>. This means to get x to one side and everything else on the other.

<h2>Solving the Questions</h2><h3>Question 1</h3>

$5x+7=15$

Because 7 is being added to x, subtract it from both sides:

$5x+7-7=15-7\\5x=8$

Because x is being multiplied by 5, divide both sides by 5:

$\dfrac{5x}{5}=\dfrac{8}{5}\\\\x=\dfrac{8}{5}$

Therefore. $x=\dfrac{8}{5}$ .

<h3>Question 2</h3>

$7x+4=5x-18$

Here, we can group all the x values on the left side of the equation. Subtract 5x from both sides:

$7x+4-5x=5x-18-5x\\2x+4=-18$

To isolate x, subtract 4 from both sides:

$2x+4-4=-18-4\\2x=-22$

Divide both sides by 2:

$\dfrac{2x}{2}=\dfrac{-22}{2}\\\\x=-11$

Therefore, $x=-11$ .

Josephine wanted to create a blueprint of her new rectangular garden she is planning on making in her backyard. She began to cre

Answer:

A: 500 square feet

Step-by-step explanation:

A: First you have to draw a grid.

You plot the points A,B, and C.

The fourth point would be -5,25 because it matches with the points.

You make a rectangle out of those points

Points AB is 2 feet. Since the interval I used was 5 I would multiply 2 by 5 to get 10.

Then I would find Points BC which is 10 feet. Again multiply it by 5 to get 50.

50 x 10 is 500.

B: Jenna has to reflect over the y-axis. This is because the y-axis is between Quadrants II and I. When reflecting over the y-axis the y-coordinate stays the same but the x-coordinate switches to it's opposite. Basically the x-coordinate is negative in Quadrant II, but in when reflecting over the y-axis the x-coordinate would change to a positive in Quadrant I. So if the point in Quadrant II looks like this: (-X,Y) then when reflecting over the y-axis to Quadrant I would look like this: (X,Y).

Answer:

Step-by-step explanation:

Y = x² - 2x + 5

x = -2

y = -2² -2(-2) + 5

y = 4 + 4 + 5 = 13

x = -1

y = -1² -2(-1) + 5

y = 1 + 2 + 5 = 8

x = 1

y = 1² -2(1) + 5

y = 1 - 2 + 5 = 4

x = 3

y = 3² -2(3) + 5

y = 9 - 6 + 5 = 8

x = 6

y = 6² -2(6) + 5

y = 36 - 12 + 5 = 29

biancas employer matches 25% of her 401(k) contributions u to $1000 biancas salary is $50000 and last year she contributed $6000

Phoenix [80]

We are told that the employer matches 25% of Bianca's contributions to her 401(k). We are also told that Bianca's salary is $50,000 a year, of which she contributed $6000 to her own 401 (k). Her salary is not necessary to solve this, simply knowing how much she put into her 401(k) is enough information.

We can solve for 25% of $6000.

$6000 x 0.25 = $1500.

The employer should contribute $1500 to her 401(k), however, the question also states that they will contribute 25% UP TO $1000. Since 25% of 6000 is greater than 1000, the employer's contribution to the 401(k) will be $1000.
