Answer:

x=8

Step-by-step explanation:

The two angles are complementary angles, so they add together to make 90 degrees

x+50 + 4x = 90

Combine like terms

5x+50 = 90

Subtract 50 from each side

5x+50-50= 90-50

5x = 40

Divide by 5

5x/ 5 = 40/5

x = 8

Rewrite the following expression.

faust18 [17]

We have been given the expression

$x^{\frac{9}{7}}$

We have the exponent rule

$x^{\frac{a}{b}}= x^{a^{(\frac{1}{b})}}$

Using this rule, we have

$x^{\frac{9}{7}}= x^{9^{(\frac{1}{7})}}$

Now, using the fact that $x^{\frac{1}{n}}=\sqrt[n]{x}$ , we get

$x^{\frac{9}{7}}= \sqrt[7]{x^9}\\
\\
x^{\frac{9}{7}}=\sqrt[7]{x^7\times x^2}\\
\\
x^{\frac{9}{7}}=x\sqrt[7]{x^2}$

D is the correct option.

On the following number line, two rational numbers are graphed.Represent the two numbers as fractions (or mixed numbers) in lowe

nordsb [41]

The first graphed rational number is at the middle of -2 and -1, thus the number represented is $-1 \frac{1}{2}$

The second graphed number is five out of six places from from 0 to 1, thus the number graphed is $0+ \frac{5}{6} = \frac{5}{6}$

The difference between the two numbers can be represented as
$-1 \frac{1}{2} - \frac{5}{6}$
or
$\frac{5}{6} -(-1 \frac{1}{2} )= \frac{5}{6} +1 \frac{1}{2}$

To find the difference,

$-1 \frac{1}{2} - \frac{5}{6} \\ \\ =-1 \frac{3+5}{6} \\ \\ =-1 \frac{8}{6} =-2 \frac{2}{6} \\ \\ =-2 \frac{1}{3}$

Also,

$\frac{5}{6} +1 \frac{1}{2} \\ \\ =1 \frac{5+3}{6} \\ \\ =1 \frac{8}{6} =2 \frac{2}{6} \\ \\ =2 \frac{1}{6}$

Solve the system by elimination

mihalych1998 [28]

Answer:

(-1, -2)

Step-by-step explanation:

4x - 7y = 10

3x + 2y = -7

The common multiple of the x coefficient is 12.

Multiple 3 to 4 to get 12; 4 to 3 to 12:

3(4x - 7y = 10)

4(3x + 2y = -7)

12x - 21y = 30

12x + 8y = -28

Subtract the two equations:

-29y = 58

y = -2

Substitute y = -2 to either 4x - 7y = 10 or 3x + 2y = -7. Typically, do the easier equation to solve:

3x + 2(-2) = -7

3x - 4 = -7

3x = -3

x = -1

The order pair solution is like a coordinate: (x, y)

You are welcome!
