Answer:

b = -3

m = 3/2

equation: [tex]y = \frac{3}{2} x - 3[/tex]

Step-by-step explanation:

b is the y-intercept, or where the line meets the y-axis.

m is the slope. rise/run = 3/2

7. Jon's car averages 20 mpg in town and 28 mpg on the road. What is the percent of decrease between the two driving conditions?

Answers

Answers:

1)10.80/12 =0.90

0.90+0.75=1.65

2)252/7=36 units

3)cost price = $9.25*225

= $2081.25

Selling price = $15.75*225

= $3543.75

Profit = Selling price - cost price

Profit = $3543.75 - $2081.25

=$1462.50

5) FV = L*(1 + rt),

Where FV is the amount to repay; L is the borrowed amount (the loan amount) and "r" is the annual interest as decimal; t is the time.

In your case L = 2400 dollars; r = 8% = 0.08 (as decimal) and t = 0.5 of a year (6 months).

Therefore,

FV = 2400*(1 + 0.08*0.5) = 2496.

In 6 months, Della Rilley must repay $2496

4) 654miles/55mph=11 hours, 53 minutes, 27 seconds ANS: ap.12 hours

time = distance/speed

6) 60*3=180mins

180/45=4

Ans: 4 days

7) This is a decrease of 8

a decrease of 28.57% rounded to two decimals

1.) 10.80 % 12 = .90 + .75 = 1.65 • 19.80

2.) 36 cases of 16 ounce were purchased

3.) a profit of 1,462.50

Explain step by step how to do 10.25 x .15.

Answers

Answer:

1.5375

Step-by-step explanation:

Multiply without the decimal points, then put the decimal point in the final answer

1025 x 15 = 15375

....

10.25 has TWO decimal places

0.15 has TWO decimal places

Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.

So the answer is 1.5375

Yes that is the answer

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!

Answers

Answer:

Step-by-step explanation:

To calculate the speed of each one we proceed as follows:

speed=distance/time

a] Noah's speed:

distance=2.5 miles

time=3/5 hours

speed=(2 1/2)/(3/5)

=(5/2)/(3/5)

=5/2×5/3

=25/6

=4 1/6 mi/hr

Emily's speed

distance=3 3/4 miles

time=5/6 hour

thus

speed=(3 3/4)/(5/6)

=15/4)/(5/6)

=15/4×6/5

=4 1/2 mi/hr

Anna's speed:

distance=3 1/3 miles

time=3/5

speed=(3 1/3)/(3/5

=(10/3)/(3/5)

=10/3×5/3

=5 5/9 mi/hr

Anna was the fastest

We have that 3 * f(x) + 4 * g(x) = h(x) where f(x), g(x), and h(x) are all polynomials in x. If the degree of f(x) is 8 and the degree of h(x) is 9, then what is the minimum possible degree of g(x)?

Answers

9514 1404 393

Answer:

Step-by-step explanation:

Adding polynomials causes like terms to be combined. The sum cannot have a degree higher than the degree of any of the terms in the sum. If the degree of f(x) is 8, then the degree of g(x) must be 9 in order for the sum to be of degree 9.
