Answer:

Step-by-step explanation:

The instructions to connect points WYXZ to make the square mean that WX and YZ are diagonals of the square. They must be mutual perpendicular bisectors. Their point of intersection is necessarily the center of the circle. That is, WX must be a diameter.

Answer:

1. To eliminate x-term, multiply the second by -2

2. To eliminate y-term, multiply the second by 3

Step-by-step explanation:

4x - 9y = 7 (1)

-2x + 3y = 4 (2)

1. To eliminate x-term, multiply the second by -2

-2x + 3y = 4 (2) × 2

-4x + 6y = 8 (3)

4x - 9y = 7 (1)

Add (3) and (1)

6y - 9y = 8 + 7

-3y = 15

y = 15/-3

y = -5

4x - 9y = 7 (1)

4x - 9(-5) = 7

4x + 45 = 7

4x = 7 - 45

4x = -38

x = -38/4

x = -9.5

4x - 9y = 7 (1)

-2x + 3y = 4 (2)

2. To eliminate y-term, multiply the second by 3

-2x + 3y = 4 (2) × 3

-6x + 9y = 12 (3)

4x - 9y = 7 (1)

-6x + 4x = 12 + 7

-2x = 19

x = 19/-2

x = -9.5

4x - 9y = 7 (1)

4(-9.5) - 9y = 7

-38 - 9y = 7

-38 - 7 = 9y

-45 = 9y

y = -45/9

y = -5

Miss white wants to buy 5 value meals at mels dinner what is a reasonable total for he purchase

bagirrra123 [75]

Answer:

Step-by-step explanation:

Here you're being asked to recall your own experience in paying for "value meals." How much have you paid per meal?

If each meal costs $6.50, then 5 would cost $13.00 before tax, and

(1.07)(5)($13.00), or $69.55 total.

Note that there's not just one possible total cost, and that we don't know much about this situation but must insert reasonable values, such as a $6.50 per meal unit cost and a 7% tax rate.

Planet Fitness charges a one-time application fee of $50 plus $30 per session for a

Vsevolod [243]

Answer:

When the number of sessions is equal to 10, the total cost is the same in the two plans

Step-by-step explanation:

Let

y ---> the total cost

x ---> the number of sessions

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

Planet Fitness

we have

The slope is equal to

$m=\$30\ per\ session$

The y-intercept or initial value is equal to

$b=\$50$

substitute

$y=30x+50$ ----> equation A

Gold's Gym

we have

The slope is equal to

$m=\$10\ per\ session$

The y-intercept or initial value is equal to

$b=\$250$

substitute

$y=10x+250$ ----> equation B

Equate equation A and equation B

$30x+50=10x+250$

solve for x

$30x-10x=250-50\\20x=200\\x=10$

therefore

When the number of sessions is equal to 10, the total cost is the same in the two plans

The inequality −8(x − 1) ≥ 88 is given. Part A: Solve the inequality and show every step of your work. (4 points) Part B: Explai

lana66690 [7]

Regarding the inequality defined by −8(x − 1) ≥ 88, we have that:

A. The solution is given by: x < -4.

B. On the number line, the solution set is composed by x = -10 and the values to the left of it.

C. Two possible solutions are x = -11 and x = -12.

<h3>Solving the inequality</h3>

The inequality is defined by:

−8(x − 1) ≥ 88

It is solved similarly to an equality, applying the distributive property and isolating the variable x, finding a range of values of x which are the solution to the inequality, as follows:

−8(x − 1) ≥ 88

8(x - 1) ≤ -88 (multiplication by -1 changes the inequality signal)

x - 1 ≤ -11 (simplify both sides of the inequality by 8).

x ≤ -10.

This the solution set is composed by the value of x = -10 and the values to the left of it, and two possible solutions are x = -11 and x = -12, which are numbers that are less than, that is, to the left of x = -10.
