Answer:

y = -3x + 18

Step-by-step explanation:

Write the problem as a mathematical expression.

m = -3, (7, -3)

Find the value of  b  using the formula for the equation of a line.

y = mx + b

b = 18

Now that the values of  m  (slope) and  b  (y-intercept) are known, substitute them into  y =  m x  +  b  to find the equation of the line.

y = -3x + 18

hope this helps :)

Answer:

y = 1/2 x+4

Step-by-step explanation:

Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.

The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].

I'll be plugging in (2,5) and (4,6) to calculate the slope.

m = (6-5)/(4-2) = 1/2

The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.

Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4

Tom made fruit punch for a party. He mixed 2 gallons of orange juice, 4 quarts of pineapple juice, 3 pints of cranberry juice, and 8 cups of apple juice. How many quarts did he make in all? (2 points)

Answers

Answer:

15.5 quarts

Step-by-step explanation:

1.5 +8 + 4 + 2

there is need to convert the measures that are not in quarts to quarts

1 gallon  = 4 quarts  : 2 x 4 = 8 quarts

1 cup = 0.25 quarts : 0,25 x 8 = 2 quarts

1 pint = 0.5 quarts : 0.5 x 3 = 1.5 quarts

Total quarts = 1.5 +8 + 4 + 2 = 15.5 quarts

2500 dollars is placed in an account with an annual interest rate of 7.25%. To the nearest year, how long will it take for the account value to reach 13100 dollars?
please help!^^

Answers

Answer:

about 58 years 6 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7.25%/100 = 0.0725 per year,

then, solving our equation

t = 10600 / ( 2500 × 0.0725 ) = 58.4828

t = 58.4828 years

The time required to

accumulate simple interest of $ 10,600.00

from a principal of $ 2,500.00

at an interest rate of 7.25% per year

is 58.4828 years (about 58 years 6 months).

Answer:

5 years

Step-by-step explanation:

Find out how much you earn a year from interest and money.

Find 1%.

100% = 2500

1% = 2500 ÷ 100 = 25

7.25% = 25 x 7.25 = 181.25

2500 + 181.25 = 2681.25

Now divide how much you earn from money and interest from 13100.

13100 ÷ 2681.25 = 4.88

4.88 estimated to 5

Percy is filling a cylindrical tank with water. The tank is

The hose he is using fills the tank at a rate of 6 cubic
meters in one minute. How long will it take Percy to fill
the tank?
A. 13 min
B. 117 min
C. 52 min
D. 468 min

Differentiate both sides with respect to time t :

Answers

Answer:

R = 30

Step-by-step explanation:

Given y is directly proportional to R² then the equation relating them is

y = kR² ← k is the constant of proportion

To find k use the condition when R = 4, y = 24, then

24 = k × 4² = 16k ( divide both sides by 16 )

1.5 = k

y = 1.5R² ← equation of proportion

When y = 1350 , then

1350 = 1.5R² ( divide both sides by 1.5 )

900 = R² ( take the square root of both sides )

[tex]\sqrt{900}[/tex] = R , that is

R = 30


It takes three quarters of an hour to lie 24 carpet tiles.
How many carpet tiles can be laid in 6 hours?

Okay so three quarters of an hour is 45 minutes.
6 hours = 360 minutes.
360/45 = 8.
So the scale factor is 8.
Just do 24 x 8 and you get the answer (192 carpet tiles)

1/6 mix + .125 cups water = 1 pancake

Multiple each by 21 to know how much mix and water it takes to make 21 pancakes

3.5 mix + 2.625 water = 21 pancakes

Answer:
