Answer:

y=3x+2

Step-by-step explanation:

slope= rise/run

rise=3  run=1 slope=3

y intercept is 2

y=3x+2

Answer:

y = 3x + 2

Step-by-step explanation:

(1, 5) and (2, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-5)/(2-1)

m=3/1

m=3

y - y1 = m(x - x1)

y - 5 = 3(x - 1)

y - 5 = 3x - 3

y = 3x + 2

Answer:

$167.50

$1507.50

$134

Step-by-step explanation:

Given that:

Cost of sound system = 1675

APR, = 12%

Down payment = 10%

Number of monthly payments = 12

r = 0.12 / 12 = 0.01

Amount of down-payment :

10% * cost of sound system

0.1 * 1675 = $167.50

Amount to be financed :

$1675 - $167.50

= $1507.50

Monthly repayment :

Using the relation :

A / {[(1+r)^n]-1}/[r(1+r)^n]

1507.5 / (1+0.01)^12-1)/(0.01(1+0.01)^12)

1507.50 / 0.1268/(0.01 * 1.1268)

1507.50 ÷ (0.1268/0.01126)

1507.50 ÷ 11.25

= $134

Answer:

27 years old

Step-by-step explanation:

What I know

Let D = Dave, S = Sabrina, etc. Then:

(1) [tex]D=0.15S[/tex]

(2) [tex]L=0.75S[/tex]

(3) [tex]R=3.00D[/tex]

(4) [tex]D+S+L+R=141[/tex]

Want to find R. Taking equation 3 and rewriting equation 4, we get

[tex]R=3.00D[/tex]

[tex]R=141-D-S-L[/tex]

So if [tex]R=R[/tex], then

[tex]3D=141-D-S-L-R[/tex]

[tex]4D=141-S-L[/tex] by adding [tex]D[/tex] to both sides.

Using equation 1 and equation 2, I can rewrite everything in terms of [tex]S[/tex] and get:

[tex]4(0.15S)=141-S-0.75S[/tex]

[tex]0.6S=141-1.75S[/tex]

[tex]2.35S=141[/tex] by adding [tex]1.75S[/tex] to both sides.

[tex]S=60[/tex] by dividing 2.35 both sides.

Now that I know Sabrina's age, I'll work towards getting Rhianna's using equation 1 and equation 3:

[tex]D=0.15(60)=9[/tex]

[tex]R=3.00(9)=27[/tex]

Checking my work:

Dave: 9

Sabrina: 60

Luca: 45 (since 9+60+45+27=141)

Rhianna: 27

9 is 15% of 60

45 is 75% of 60

27 is 300% of 9

Answer:

-26x

Step-by-step explanation:

(9x 2 −8)−(−4x 2 −5x)

(9x)(2-8)-(4x)(2-5x)

^separating x so i can distribute but the ones that are sitting weirdly in the  parentheses (see how there isnt a sign separating 9x and 2? im going to seperate them via parentheses which is the same thing as adding a sign there. Same with -4x and 2)

we are going to distribute now. 9x*2, 9x*-8 -4x*2 -4x*-5x

(18x-72x) - (-8x+20x)

Its going to look like this ^

add or subtract the stuff in the parentheses

-54x+28x

-26x

Answer:

your answer will be 4/25

Step-by-step explanation:

Answer: 7.5 miles per hour

Step-by-step explanation:

First speed was 3 miles per hour.

Second speed was 12 miles per hour.

To do an average, add both speeds and divide by two, which is the number of trips made.

= (3 + 12) / 2

= 15 / 2

= 7.5 miles per hour

The Fundamental Counting Theorem states that if there are n independent trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, the total number of outcomes is calculated by the multiplication of the number of outcomes for each trial as presented as follows:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

For this problem, we have that the parameters are given as follows:

Hence the total number of combinations is given as follows:

N = 26³ x 10³

N = 17,576,000

Answer:

$20.40 after the discount

Step-by-step explanation:

To find 15% of 24, you multiply 24 and 0.15, which gets you 3.6

Then, to find the price after the discount, you subtract the 15% (the 3.6). So, 24 - 3.6 = $20.40
