<h3><u>The value of x is 19.</u></h3><h3><u>The value of y is 4.</u></h3>

x = 3 + 4y

x + y = 23

Because we have a value for x we can plug it directly into the second equation.

3 + 4y + y = 23

Subtract 3 from both sides.

4y + y = 20

Combine like terms.

5y = 20

Divide both sides by 5.

y = 4

Plug this value for x back into the original equation.

x = 3 + 4(4)

x = 3 + 16

x = 19

Which of the following are solutions to the quadratic equation? Check all that
Reil [10]

Answer:

x=-9/10

Step-by-step explanation:

2x+8x+16=7

Step 1: Simplify both sides of the equation.

2x+8x+16=7

(2x+8x)+(16)=7(Combine Like Terms)

10x+16=7

10x+16=7

Step 2: Subtract 16 from both sides.

10x+16−16=7−16

10x=−9

Step 3: Divide both sides by 10.

10x/10

=

−9/10

x=-9/10

Answer:

median: 86.5 <em>2)</em> 50.9% <em>3) </em>36.18 or 36.2 rounded

Step-by-step explanation:

To find the median, you have to order all of the numbers in a sequence from smallest to largest, and pick the number in the middle.

You'd order this sequence:

70, 77, 79, 84, 86, 87, 87, 91, 91, 91

The number in the middle is:

between 86, 87 the amount of numbers in the sequence is an even number.

The number between these two numbers, however, is <em>86.5</em>

<em>2)</em>

140/275 = .509 or 50.9%

3)

.18 x 201 = 36.18 or 36.2

A graphing calculator can be helpful for these.

A) Since neither inequality includes the "or equal to" case, the boundary line for the solution set is a dashed line. For the first inequality, the shading is above the line; for the second, the shading is below the line. The solution set is points to the right of perpendicular lines with slope -2 and +1/2 through point (2, -1).

B) The point -2, 3 satisfies, neither inequality.
