Answer: For the graph,

43. y=2.5x−4

45. y=−15x+3

47. y=12x+−94

Step-by-step explanation:

43.

Let's solve for x.

y=2.5x−4

Step 1: Flip the equation.

2.5x−4=y

Step 2: Add 4 to both sides.

2.5x−4+4=y+4

2.5x=y+4

Step 3: Divide both sides by 2.5.

2.5x2.5=y+42.5

x=0.4y+1.6

Answer:

x=0.4y+1.6

45.

Let's solve for x.

y+15x=3

Step 1: Add -y to both sides.

15x+y+−y=3+−y

15x=−y+3

Step 2: Divide both sides by 1/5.

15x15=−y+315

x=−5y+15

Answer:

x=−5y+15

47.

Let's solve for x.

2x−3=4y+6

Step 1: Add 3 to both sides.

2x−3+3=4y+6+3

2x=4y+9

Step 2: Divide both sides by 2.

2x2=4y+92

x=2y+92

Answer:

x=2y+92

If you would like to know the interquartile range of the new set and the interquartile range of the original set, you can do this using the following steps:

<span>The interquartile range is the difference between the third and the first quartiles.

The original set: </span>69, 70, 72, 72, 74, 74, 74, 75, 76, 76, 76, 77, 77, 82
Lower quartile: 72
Upper quartile: 76.25
Interquartile range: upper quartile - lower quartile = 76.25 - 72 = <span>4.25
</span>
The new set: <span>70, 72, 72, 74, 74, 74, 75, 76, 76, 76, 77, 77
</span>Lower quartile: 72.5
Upper quartile: 76
Interquartile range: upper quartile - lower quartile = 76 - 72.5 = 3.5

The correct result would be: T<span>he interquartile range of the new set would be 3.5. The interquartile range of the original set would be more than the new set.</span>

Harry church borrowed 17,500.00 at 6.5% exact interest. He had to pay back a maturity value of 17,873.97 to pay off the loan. Wh
kirill [66]

Answer:the term of the loan is approximately 4 months

Step-by-step explanation:

The term of the loan means the period for which the loan was given.

We would apply the formula for simple interest which is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

P = 17500

R = 6.5%

I = total amount paid - principal

I = 17,873.97 - 17,500.00 = 373.97

Therefore

373.97 = (17500 × 6.5 × T)/100

373.97 = 1137.5T

T = 373.97/1137.5

T = 0.32 years

Converting to months, it becomes

0.32 × 12 = 3.84

Approximately 4 months.
