Answer:

n = -1

Step-by-step explanation:

Use the equation y=mx + b

m (slope) = -2

x (x coordinate) = -4

y (y coordinate) = 7

You are solving for b.

Plug in for the given values:

7 = -2(-4) + b

7 = 8 + b

-1 = b (Minus both sides by 8)

y= -2x -1

Therefore, n = -1

I'll just do red for now, but if you're very desperate I guess I'll help with a few more lol. It's just a lot of typing and my computer is at 6% :)

RATIO:

Ratios are another way of comparing things. It's almost like a fraction, except that it can look like x:y.

I'm guessing you're comparing all of the reds to the total amount, which should be 39. Put 5 in for x and 39 for y to make it look like 5:39.

DECIMAL:

Oh decimals are so fun...

Just divide 39 by 5. The answer to red's decimal is 7.8.

PERCENTAGE:

Percentage can come a little bit confusing to some people, so I'll explain this the best I can.

Basically, all you have to do to find it is divide the number you're making into a percentage by the total amount, then multiply it.

5/39 x 100

0.1282051282 x 100

12.8205128205

I'm going to the nearest hundredth which is 12.82.

Your percentage is %12.82

(If you're rounding to the nearest whole number, it'll be %13)

THEORETICAL:

For this simplify your ratio. 5/39 cannot simplify, so just leave it as 3/39.

Sorry, sometimes I come out a little confusing, so just try not to think too hard about what I'm trying to say if you're confused more lol. Anyway my computer is going to die so I'll go now :)

Average rate of change of the function =\frac{75}{2}

Solution:

Given function: f(x)=5(2)^{x} from x = 1 to x = 5

Substitute x = 1 and x = 5 in f(x).

f(1)=5(2)^{1}=10

f(5)=5(2)^{5}=160

Let us find the average rate of change of the function.

Average rate of change

                      $=\frac{f(b)-f(a)}{b-a}

Here a = 1 and b = 5.

                     $=\frac{f(5)-f(1)}{5-1}

Substitute f(5) and f(1).

                     $=\frac{160-10}{4}

                     $=\frac{150}{4}

                     $=\frac{75}{2}

Average rate of change of the function =\frac{75}{2}

Help pls help I will mark brainlist​

Answer:

x = 20

y = 5

Step-by-step explanation:

<u>Adjacent angles of a parallelogram are supplementary</u> (add up to 180°).

So,

6x + 17 + 2x + 3 = 180

Combine like terms

6x + 2x + 17 + 3 = 180

8x + 20 = 180

Subtract 20 to both sides

8x = 180 - 20

8x = 160

Divide 8 to both sides

x = 160 / 8

x = 20

Now,

<u>Opposite sides of parallelogram are equal.</u>

So,

JK = ML

6y - 13 = 32 - 3y

Add 3y and 13 to both sides

6y + 3y = 32 + 13

9y = 45

Divide 9 to both sides

y = 45 / 9

y = 5

\rule[225]{225}{2}

Hope this helped!

NikAS [45]

Answer:

Step-by-step explanation:

1.g(x)=(1/3x)^3

solve for x : gx= x^3/27

solve for g: g= x^2/27

2. g(x)=(x-4)^3-3

x= 1/g
