Answer:

1) y = (x + 8)² + 7; 5) y = (x - 6)² + 10; 7) y = (x - 3)² - 4

Step-by-step explanation:

Complete the square in order to figure these out. To complete the square, use the formula [½B]². Each time you do this, you get a perfect trinomial in the form of a product of two monomials [h], then you have to figure out how much more to deduct from or add on to your C they gave you in each exercise [k].

Step-by-step explanation:

Use the distributive property to get $2xy-14$ (you multiply both xy and -7 by 2.) Now plug in the x and y values to get: $2(-1)(3)-14$ . This gets you $-6-14$ which is $-20$ .

What is the slope of the line through the points (-3,3) and (6,-8)

STatiana [176]

Answer:

$\displaystyle \frac{-11}{9}$

Step-by-step explanation:

We will use the equation of change in y over change in x to solve for the slope of the line. Then, we will simplify.

$\displaystyle \frac{y_{2}-y_1 }{x_2-x_1}$

$\displaystyle \frac{-8-3}{6--3}$

$\displaystyle \frac{-8-3}{6+3}$

$\displaystyle \frac{-11}{9}$

Answer:

$22,360

Step-by-step explanation:

Whenever you have a percentage increase, multiply the original value with the percent in decimal form plus one. For example, $21,500 increased by 4% is the equivalent to 21,500 * 1.04. If it decreased by 8%, you would do 21,500 / 1.08.
