A baker, in 70 minutes, iced 40 cupcakes and, in 49 minutes, iced 28 cupcakes. What is the constant of proportionality?

Zinaida [17]

Answer:

$\frac{4}{7}$

Step-by-step explanation:

The constant of proportionality is the slope of the line joining the two points

(70,40) and (49,28).

Recall the slope formula:

$m = \frac{ y_2 - y_1 }{ x_2 - x_1}$

We substitute the point to get:

$m = \frac{28 - 40}{49 - 70} = \frac{ - 12}{ - 21} = \frac{4}{7}$

Alternatively:

A proportional relation is given by

$y = kx$

where k is the constant of proportionality.

Using any point, we substitute and solve for k.

$40 = 70k$

$k = \frac{40}{70} = \frac{4}{7}$

Maru [420]

Answer:

To get the function g, shift f down by 8 units.

Step-by-step explanation:

The constant - 8 at the end of function g(x) suggests the parent function f(x) was translated 8 units down.

Find the hcf of px4 + px ,qx3 _ qx

Deffense [45]

Step-by-step explanation:

1st expression

= px^4 + px

= px ( x³ + 1 )

= px ( x + 1) (x² - x + 1)

2nd expression

= qx³ - qx

= qx ( x² - 1 )

= qx ( x + 1) ( x - 1)

HCF = x ( x + 1)

Hope it will help :)❤
