Kira owes her mom $125 and is planning to to payer back with payments $7 a week. Write an equation in slope-intercept form that

cricket20 [7]

Answer:

y = 17(7) + 6

Step-by-step explanation:

Given that:

Amount owed = $125

Payment per week = $7

Number of whole weeks to pay :

$125 / $7 = 17.85 = 17 whole weeks

$125 - (17 * 7) = $125 - $119 = $6

Using slope intercept notation :

y = mx + c

Where m = slope ; c = intercept. ;

m = 17,; x = $7, c = $6

y = 17(7) + 6

A cylindrical tube 9.5 cm high and 0.85 cm in diameter is used to collect blood samples. How many cubic decimeters (dmଷ ) of blo

Brums [2.3K]

Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.

Step-by-step explanation:

Volume of cylinder= volume of blood it can hold = $\pir^2h$

Given :

Height of cylinder (h) = 9.5 cm

Diameter of cylinder (d) = 0.85 cm

Thus radius of cylinder (r) = $\frac{\text {Diameter of cylinder}}{2}=\frac{0.85cm}{2}=0.425cm$

Putting the values we get:

Volume of cylinder= volume of blood it can hold = $3.14\times (0.425cm)^2\times 9.5cm=5.39cm^3=0.539dm^3$ [tex] (1cm=0.1dm)

Thus 0.539 cubic decimeters of blood can be hold by the cylinder.

4. Write an equation for the line that is parallel to the given line and that passes

pentagon [3]

Answer:

$y=\frac{5}{2}x-14$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope (m)

$y=\frac{5}{2}x-10$

In the given equation, $\frac{5}{2}$ is in the place of m, making it the slope. Because parallel lines have the same slope, the line we're currently solving for therefore has a slope of $\frac{5}{2}$ . Plug this into $y=mx+b$ :
