Which of the following is a linear function?
A: y = 3x^2.
B: y = 1/3x.
C: y = x^3 + 5.
D: 2/3 x = y - 1

Answers

B is the answer to you problem:)

Answer:

y= 1 over 3x

Step-by-step explanation:

Solve 7(y + 2) – (4y – 10) = 44 – 2y + 5
A.y = -5
B.y = 5
C.y = -10

Answers

Answer:

y = 5

Step-by-step explanation:

7(y + 2) – (4y – 10) = 44 – 2y + 5

(7y+14) - (4y - 10) = 49 -2y

3y +24 = 49 -2y

5y +24 = 49

5y = 25

y = 5

Answer:

y=5

Step-by-step explanation:

7(y+2)-(4y-10) = 44-2y+5 distribute on the left and combine like terms on the right side of the equation

7y + 14 -4y +10 = 49 - 2y move every term with a variable on the left side with a change sign and the numbers on the right side

7y-4y+2y =49 -14 -10

5y = 25 divide both sides by 5

y5/5=25/5 so

y=5

solve for r: q = p(r + s)

Answers

Answer:

[tex]r=\frac{q-ps}{p}[/tex]

General Formulas and Concepts:

Order of Operations: BPEMDASEquality PropertiesDistributive Property

Step-by-step explanation:

Step 1: Define equation

[tex]q=p(r+s)[/tex]

Step 2: Solve for r

Distribute p:                              [tex]q=pr+ps[/tex]Subtract ps on both sides:       [tex]q-ps=pr[/tex]Divide both sides by p:            [tex]\frac{q-ps}{p} =r[/tex]Rewrite:                                     [tex]r=\frac{q-ps}{p}[/tex]

Step-by-step explanation: To solve for r, start by distributing the p

through the parentheses on the left side to get q = pr + ps.

Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.

Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.

Answers

Answer:

x + 2x = 108

Step-by-step explanation:

Let x be the number of oranges sold on Thursday

The number of oranges sold on Friday is twice as many or 2 times x, 2x

The total sold on  the two days is 108.  Add the number sold on Thursday and Friday together and let it equal to 108

x + 2x = 108

So lets say you sold ‘x’ number of oranges on Thursday.On Friday you sold double,therefore ‘2x’. And altogether combining the sales on Thursday and Friday you sold 108 oranges. Therefore if we add the number of oranges sold on Thursday and Friday we will get 108 oranges.
The equation will be: x(number of oranges sold on Thursday) + 2x( number of oranges sold on Friday) = 108 (total number of oranges sold altogether)
x + 2x = 108

Step-by-step explanation:

I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)

P/w = part/whole = ?/400

%/100= percent/100 = 30%/100

These numbers are equivalent

If you don’t understand the top then here is how to do the work-

Answers

Answer:

1. $3.80 + 2.60=$6.40 *.05=$5.08  

$20.00-$5.08=$14.92

2. $360 x %40=$14,000

$14,000/100=144   360-144 = 216

$216 x %20 = $4,320/$100= $43.20

$216-43.20= $172.8

Answers

Answer:

3/4

Step-by-step explanation:

If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in

1/4(x)=y

1/4(3)=y

3/4=y

And the other one is incorrect

1/4(x)=y

1/4(7)=y

Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.

How many loaves of banana bread can she make?

Answers

Answer:

69 loaves

Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)

First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.

So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread

Answer:
70.57 loaves of banana bread
Explaintion:
1,623 ➗ 23 = 70.5652173913043
Rounded: 70.57

No Sarah is not correct. If you replace x with 1, the first equation would equal 5, but the second equation would equal 1. In addition, when she tried to do the inverse operation, she did the inverse operation on the factors, not the operation.

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.

Answers

Answer:

Step-by-step explanation:

Given

There are 9 people going on a trip

They purchased coach tickets =$160

first class tickets =$1180

total budget to spend = $4500

Let coach tickets=X

So first class tickets=9-x

160x+1180(9-x)=4500

160+10620-1180x=4500

160x-1180x=4500-10620

-1020x=-6120

X=6120/1020

X=6

So answer

Coach tickets=X=6

First class tickets=(9-x)
