Answer:

Step-by-step explanation:

Charge of 9 gigs for A

find slope:

125 - 95/5 - 3 = 30/2 = $15/month

use point slope form with point (3,95) and slope 15:

y - y1 = m(x - x1)

y - 95 = 15(x - 3)

y - 95 = 15x - 45

+ 95 +95

y = 15x + 50

put 9 for x, gigs, in the new equation:

y = 15(9) + 50

y = 135 + 50

y = 185

$185 for opt A

Charge of 9 gigs for B

slope = 0

there is the fee of 150 so the equation is:

y = 0x + 150

Next find the price for 9 gigs

y = 9(0) + 150

y = 150

$150 for opt B

Charge of 9 gigs for C

use graph and the cost is about $157

A: $185

B: $150

C: $157

Can someone help out I’m really slow at this and don’t understand it please:)

myrzilka [38]

Answer:

2) 160

3) 320

Step-by-step explanation:

you want to find out the slope so use the formula

y₂-y₁/ x₂-x₁ and plug in the numbers

320-80=240

4-1=3

divide 240/3= 80

multiply 80 * (x) so if we try and find x=2 it would be 160

80 * 3 = 240

check your work by multiplying 80 and 4 (320) which is your y value! hope this helps!

Colin’s piano lesson is 45 minutes, or Three-fourths of an hour, long. If he practices 6 different songs and spends an equal amo

NikAS [45]

Answer:

Colin spends 1/8 of an hour practicing each song

Step-by-step explanation:

Colin's piano lesson is 3/4 of an hour, long.

In that period, he practices 6 different songs, spending an equal amount of time on each one.

This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:

$\displaystyle \frac{\frac{3}{4}}{6}=\frac{3}{24}=\frac{1}{8}$

Colin spends 1/8 of an hour practicing each song

Which expressions are equivalent to Negative 9 (two-thirds x + 1)? Check all that apply.

Sav [38]

Answer:

$-9(\frac{2}{3}x) + 9(1)\\ \\-6x + 9$

Explanation:

Before we begin, remember the following rules:

1- Distribution property:

$a(b+c) = ab+ac$

2- Simplification of fractions:

$\frac{xy}{yz}=\frac{x}{z}$

3- Signs in multiplication:

+ve * +ve = +ve

-ve * -ve = +ve

+ve * -ve = -ve

Now, for the given problem, we have:

$9 (\frac{2}{3}x + 1)$

Starting with the distributive property:

$-9 (\frac{2}{3}x +1) = -9(\frac{2}{3}x) - (-9)(1) = -9(\frac{2}{3}x) + 9(1)$

..................>This corresponds to option 1

Now, we simplify the output from the above step:

$-9(\frac{2}{3}x) + 9 = \frac{-9*2}{3}x + 9 = -6x+9$

................> This corresponds to option 5

Hope this helps :)
