Step-by-step explanation:

you understand what is the meaning of an exponent ?

or did you not pay any attention in class ?

an exponent indicates how often the base value has to be multiplied by itself.

e.g.

4⁵ = 4×4×4×4×4

9³ = 9×9×9

therefore,

400² = 400 × 400 = 160,000

Write a equation for (-6, -3)
Vlad [161]

<u>Answer</u>:

equation: y = x/2

<u>Explanation</u>:

let the points be  (-6, -3) ,  ( 0, 0)

slope: \frac{y2-y1}{x2-x1}

         : \frac{0--3}{0--6}

         : \frac{1}{2}

Equation using:

y - y1 = m ( x - x1 )

y - - 3 = 1/2( x - - 6 )

y + 3 = x/2 + 3

y\\ = \frac{x}{2}

Suppose you know that &lt;T and&lt;S are supplementary, and that m&lt;T=3(m&lt;S). How can you find m&lt;T?​
stealth61 [152]

Answer:

∠T = 135°

Step-by-step explanation:

Supplementary angles sum to 180°, thus

∠T + ∠S = 180

However, ∠T = 3∠S, hence

3∠S + ∠S = 180

4∠S = 180 ( divide both sides by 4 )

∠S = 45°, hence

∠T = 180° - 45° = 135°

Write the equation of the line in slope-intercept form that passes through
never [62]

Answer:

y= -2/3x+3

Step-by-step explanation:

Parallel lines have the same slope but different y-intercepts.

y=-2/3x is your original equation

Your slope is still -2/3

y=mx+b

y=-2/3x + b

Substitute the points from the coordinates

5 = -2/3(-3) + b

5 = 2 + b

-2   -2

b=3

Your parallel line equation is: y= -2/3x+3

Have a great day!
