0.7(-c+9)-0.5c i need to rewrite the equation in sinplest terms by the way

Preform the indicated multiplication below. reduce the terms and simplify (2+i)(3-i)(1+2i)(1-i)(3+i)

lbvjy [14]

Answer:

Hey there!

Expand (2+i)(3-i). You should get 7+i

Expand (7+i)(1+2i). You should get 5+15i

Expand (5+15i)(1-i). You should get 20+10i

Expand (20+10i)(3+i). You should get 50+50i as your final answer.

Let me know if this helps :)

The National Football League has performed a study in which the total yards gained by teams in games was used as an independent

luda_lava [24]

Answer:

C

Step-by-step explanation:

A regression model is a function which can be used to predict behavior of the model. It takes data points in and forms a general pattern for the pattern using an equation. This model y = 12.3 + 0.12x is a linear regression model which means it has linear behavior (a line) where x is total yards gained and y is number of points scored. If one additional yard is gained then the score is likely to be 12.3 + 0.12(1) = 12.42. If two additional yards is gained then the score is likely to be 12.3 + 0.12(2) = 12.54. Notice the score increases by 0.12 points for every yard gained. This is answer choice C.

a.)The average points scored for teams who gain zero yards during a game is -12.3 points.

b.) The average yards gained will increase by .12 for every additional point scored.

c.) The average change in points scored for each increase of one yard will be 0.12.

d.) The average number of points scored per game is 12.3.

Solve each equation using inverse operations: 1. 9w = -54 2. b - 12 = 3 3. n/4 = -11

katovenus [111]

Hello!

Answer:

1. $\boxed{W=-6}$

*The answer must have A NEGATIVE SIGN ONLY!*

2. $\boxed{B=15}$

*The answer must have A POSITIVE SIGN ONLY!*

3. $\boxed{N=-44}$

*The answer must have a NEGATIVE SIGN ONLY!*

Step-by-step explanation:

1. 9w=-54

First, you divide by 9 both sides of an equation.

9w/9=-54/9

Simplify.

-54/9=-6

W=-6 is the final answer.

____________________________________

2. b-12=3

First you add by 12 both sides of an equation.

b-12+12=3+12

Add by the numbers from left/right.

3+12=15

b=15 is the final answer.

__________________________________________

3. n/4=-11

First you multiply by 4 both sides of an equation.

4n/4=4(-11)

Multiply by the numbers from left/right.

4*-11=-44

n=-44 is the final answer.

Hope this helps you!

Have a great day! :)

To serve 1 person at a local restaurant it takes 10 minutes to serve 5 people it takes 18 minutes what is the point slope form

zhannawk [14.2K]

Answer:

$y-1=\frac{1}{2}(x-10)$

Step-by-step explanation:

Let

x------>the time in minutes

y----> the number of people

we know that

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

we have

$A(10,1),B(18,5)$

Find the slope

$m=\frac{5-1}{18-10}$

$m=\frac{1}{2}\frac{people}{minutes}$

with the slope m and the point A find the equation of the line

$y-1=\frac{1}{2}(x-10)$ -----> point slope form
