$(\frac{ a^{-3} }{ b^{2} }) ^{4} = \frac{ a^{-3*4} }{ b^{2*4} } = \frac{ a^{-12} }{ b^{8} } =
 \frac{1}{ a^{12} b^{8} }$

Write the standard form of the equation of the line described

tiny-mole [99]

Hello!

First you have to find what y is at when x is -3 in the first equation

y = 5/3(-3) + 2

y = -3

A point of the original line is (-3, -3)

The line we want has to go up 2

To do this we add 2 to the y-intercept part of the equation

y = ? + 2 + 2

Since the line is parallel it has the same slope

y = 5/3x + 2 + 2

Simplify

The answer is y = 5/3 x + 4

Hope this helps!

A right triangle has side lengths a, b, and c as shown below.

Musya8 [376]

Answer:

$\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}$

Step-by-step explanation:

Given that

A right triangle has side lengths a, b, and c

Because you did not attached photo of the right triangle so I will assume that:

Side a is the adjacent (A)
Side b is the opposite (O)
Side c is the hypotenuse (H)

(Please have a look at the attached photo)

To solve for the trigonometric functions of x, we need to recall the ratios they represent as shown below.

$\sin x = \frac{O}{H}\\\cos x = \frac{A}{H}\\\tan x = \frac{O}{A}$

EX: the sine of x is equal to the side opposite of angle x over the hypotenuse. Hence, we have the expressions of the trigonometric functions as shown below:

$\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}$

Hope it will find you well

Camryn ate 3 feet of spaghett each day for a week, how many yards of spaghetti did she eat in all

stepan [7]

She ate 7 yards. This is because 3 feet=1 yard, so you can say that she ate 1 yard per day, for 7 days, so that makes it 7 yards.

8x + 4(x – 1) = 15x – 10

Naily [24]

Answer:

x = 2

Step-by-step explanation:

Solve for x:

8 x + 4 (x - 1) = 15 x - 10

Hint: | Distribute 4 over x - 1.

4 (x - 1) = 4 x - 4:

4 x - 4 + 8 x = 15 x - 10

Hint: | Group like terms in 8 x + 4 x - 4.

Grouping like terms, 8 x + 4 x - 4 = (8 x + 4 x) - 4:

(8 x + 4 x) - 4 = 15 x - 10

Hint: | Add like terms in 8 x + 4 x.

8 x + 4 x = 12 x:

12 x - 4 = 15 x - 10

Hint: | Move terms with x to the left hand side.

Subtract 15 x from both sides:

(12 x - 15 x) - 4 = (15 x - 15 x) - 10

Hint: | Combine like terms in 12 x - 15 x.

12 x - 15 x = -3 x:

-3 x - 4 = (15 x - 15 x) - 10

Hint: | Look for the difference of two identical terms.

15 x - 15 x = 0:

-3 x - 4 = -10

Hint: | Isolate terms with x to the left hand side.

Add 4 to both sides:

(4 - 4) - 3 x = 4 - 10

Hint: | Look for the difference of two identical terms.

4 - 4 = 0:

-3 x = 4 - 10

Hint: | Evaluate 4 - 10.

4 - 10 = -6:

-3 x = -6

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 x = -6 by -3:

(-3 x)/(-3) = (-6)/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

x = (-6)/(-3)

Hint: | Reduce (-6)/(-3) to lowest terms. Start by finding the GCD of -6 and -3.

The gcd of -6 and -3 is -3, so (-6)/(-3) = (-3×2)/(-3×1) = (-3)/(-3)×2 = 2:
