Answer:

b=6

$a^{2} + b^{2} = c^{2} \\ {8}^{2} + {b}^{2} = {10}^{2} \\ 64 + {b}^{2} = 100 \\ 100 - 64 = {b}^{2} \\ 36 = {b}^{2} \\ \sqrt{36} = \sqrt{ {b}^{2} } \\ 6 = b$

Answer:

x = 10.5 in

Step-by-step explanation:

The rectangles are similar, thus the ratios of corresponding sides are equal.

that is $\frac{7}{2}$ = $\frac{x}{3}$ ( cross- multiply )

2x = 21 ( divide both sides by 2 )

x = 10.5

$\huge\text{Hey there!}$

$\mathsf{2(4 - 1)^2 - 3 + 2(5)}$

$\mathsf{4 - 1 = \bf 3}$

$\mathsf{= 2(3^2) - 3 + 2(5)}$

$\mathsf{3^2}\\\mathsf{= 3\times3}\\\mathsf{= \bf 9}$

$\mathsf{= 2(9) - 3 + 2(5)}$

$\mathsf{2(9)}\\\mathsf{= \bf 18}$

$\mathsf{= 18 - 3 + 2(5)}$

$\mathsf{18 - 3}\\\mathsf{= \bf 15}$

$\mathsf{= 15 + 2(5)}$

$\mathsf{2(5)}\\\mathsf{= \bf 10}$

$\mathsf{= 15 + 10}\\\mathsf{= \bf 25}$

Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x-3y=13 4x-y=-9

Tems11 [23]

2x -3y = 13

4x -y = -9

Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.

4x -y = -9 x -3 = -12x + 3y = 27

Now add this to the first equation:

2x -12x = -10x

-3y +3y = 0

13 +27 = 40

Now you have :

-10x = 40

Divide each side by -10:

x = 40 / -10

x = -4

Now you have a value for x, replace that into the first equation and solve for y:

2(-4) - 3y = 13

-8 - 3y = 13

Add 8 to both sides:

-3y = 21

Divide both sides by -3:

y = 21/-3

y = -7

Now you have X = -4 and y = -7

(-4,-7)
