valkas [14]

I'm assuming you didn't mean to repeat each number 3 times.

If she did 184 jumping jacks in 4 minutes that means she did 46 jumping jacks per minute.

Find the product.<br> (3n - 1)(7n-7)

slega [8]

Answer:

21n² - 28n + 7

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

3n(7n - 7) - 1(7n - 7) ← distribute both parenthesis

= 21n² - 21n - 7n + 7 ← collect like terms

= 21n² - 28n + 7

The equation in slope intercept form

Solving (3):

$m = -1$

$(x_1,y_1) =(4,-4)$

The equation in slope intercept form is:

$y = m(x - x_1) + y_1$

This gives:

$y = -1(x - 4) -4$

Expand

$y = -x + 4 -4$

$y = -x$

Solving (5):

$m = -3$

$(x_1,y_1) = (1,-5)$

The equation in slope intercept form is:

$y = m(x - x_1) + y_1$

This gives:

$y = -3(x - 1) - 5$

Expand

$y = -3x + 3 - 5$

$y = -3x -2$
