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

equation - im assuming you wanted slope-intercept form (y=mx+b)

Write an equation for the trend line shown

Answer:

y= -x + 225

Step-by-step explanation:

it has a negative slope so -x

it crosses the y axis at (0,225)

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

Answer:

  9

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.

Jack needs 22 pirates for every 2 pirate ships he manages.

Answers

Answer:

55, 121

Step-by-step explanation:

2*2 =4

22*2=44

but 4 is not the number we need and 4 is one less so we divide 22 by 2 and get 11 so 44+11=55

thats the first box.

The second box is 55*2+11 which is 121

55:is the first box

121 is the second empty box

55 pirates for 5 ships
And
122 pirates for 11 ships

22 pirates for every two ships that would be 11 pirates for every 1 ship so your basically adding 11 to every ship there

The ratio would be 11:1

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

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
