Problem 5)

The bases are the same, so we add the exponents when multiplying something like this out. We have -5+7 = 2 as the final exponent meaning that 5^2 = 25

<h3>Answer: Choice B) 25</h3>

=============================================

Problem 6)

We can multiply the exponents (t^8)^2 = t^(8*2) = t^16

Or we can expand out (t^8)^2 to get (t^8)*(t^8), then add the exponents from here to get t^(8+8) = t^16. Either way we get the same answer

<h3>Answer: Choice C) t^16</h3>

=============================================

Problem 7)

The negative exponent indicates we will apply the reciprocal to get that exponent to a positive number. The rule is x^(-k) = 1/(x^k)

So 5^(-4) = 1/(5^4) = 1/625 and (t^3)^(-4) = t^(3*(-4)) = t^(-12) = 1/(t^12)

Put together, we end up with 1/(625t^12)

<h3>Answer: Choice C) 1 over 625t^12</h3>

M = 1/2 (0, -3)<br> Write the equation of a line using slope intercept form
marshall27 [118]

Answer:

y=\frac{1}{2}x-3

Step-by-step explanation:

slope intercept form is y=mx+b

b is y intercept

so we plug the coordinate into the equation

-3=\frac{1}{2}(0)+b

-3=b

so y intercept is -3

so we then write our equation which is,

y=\frac{1}{2}x-3

zhuklara [117]

Answer:

Computer disks are $4 each

Notebooks are $3 each

Step-by-step explanation:

For the first equation

<em>$4 x 2 disks = $8</em>

<em>$3 x 3 notebooks = $9</em>

<em>$9 + $8 = </em>$17

For the second equation

<em>$4 x 5 disks = $20</em>

<em>$3 x 4 notebooks = $12</em>

<em>$20 + $12 = </em>$32

Which set of angle measures could be the interior angles of a triangle?
andriy [413]

Answer:

d. 15, 30, 135

Step-by-step explanation:

A triangle's interior angles on a flat surface add up to 180 degrees.

a. 90 * 3 = 270 != 180

b.(80 * 2) + 200 = 360 != 180

c.40 + 50 + 60 = 160 != 180

d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.
