Answer: x = 8, x = 5

Step-by-step explanation:

first problem: first, we collect like terms

3x + 3 = 2x + 11

then, we move the terms around.

3x - 2x = 11 - 3

finally, we collect those like terms and calculate.

x = 8

second problem: first, we rewrite the expression

2 x 3x + 1 = 2x + 21

then, we calculate.

6x + 1 = 2x + 21

next, we move the terms,

6x - 2x = 21 - 1

then, we collect the like terms.

4x = 20

finally, we divide both sides.

x = 5

What is the length of z? (Round to the nearest tenth)

navik [9.2K]

Answer:

z = 10.8

Step-by-step explanation:

$9^{2} + 6^{2} = c^{2}$

81 + 36 = $c^{2}$

117 = $c^{2}$

c = $\sqrt{117}$

c = 10.8

c = z

Find the solution set of the following equations: 2y=2x+7 X=y+2

kirill115 [55]

Answer:

The system of equations has no solution.

Step-by-step explanation:

Given the system of equations

2y = 2x+7

x = y+2

solving the system of equations

$\begin{bmatrix}2y=2x+7\\ x=y+2\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}2y-2x=7\\ -y+x=2\end{bmatrix}$

Multiply -y+x=2 by 2: -2y+2x=4

$\begin{bmatrix}2y-2x=7\\ -2y+2x=4\end{bmatrix}$

so adding

$-2y+2x=4$

$+$

$\underline{2y-2x=7}$

$0=11$

so the system of equations becomes

$\begin{bmatrix}2y-2x=7\\ 0=11\end{bmatrix}$

0 = 11 is false, therefore the system of equations has no solution.

Thus,

No Solution!

Find the constant of proportionality (r) in the equation y=rx

ahrayia [7]

Answer:

r = $\frac{1}{4}$

Step-by-step explanation:

Given the proportional equation

y = rx ← r is the constant of proportion

Divide both sides by x

$\frac{y}{x}$ = r

Use any ordered pair from the table.

Using (8, 2 ) , then

r = $\frac{2}{8}$ = $\frac{1}{4}$

Answer:

- sign between 9 and 64 under root, it should be + sign

Step-by-step explanation:

(-4)*(-8)(2)= 64

It should read x= √9+64 but not √9-54 which lead to incorrect solution
