Answer:

(-4, 0) and (-5, 0)

Step-by-step explanation:

You will need to need to plug in (-4, 0) and (-5, 0) in the equation.

(x + 4) (x + 5) = y. (-4, 0)

(-4 + 4) (-4 + 5) = 0

(0) (1) = 0

0 = 0

This means that (-4, 0) is a solution to the equation. Now let us find if (-5, 0) is a solution to the equation.

(x + 4) (x + 5) = 0. (-5, 0)

(-5 + 4) (-5 + 5) = 0

(-1) (0) = 0

0 = 0

So, (-5, 0) is also the answer to the equation. Hope this helps, thank you :) !!

Carrie sees a dress she wants that usually sells for $109. The dress is on sale at 15% off and sales tax is 6.5%. How much will

pychu [463]

Answer:

$98.67

Step-by-step explanation:

109(.15)= $16.35 You multiply by .15 to find out what 15% of the total (109) is going to be discounted.

109-16.35= 92.65 You subtract the discount from the total to come up with the new total.

92.65(1.065)= 98.67225 =98.67 You take the discounted total, 92.65, and multiply it by 1.065 which represents how you will will be paying for sales tax.

. Which of the following quartic functions has x = -2 and x=-3 as its only two real zeros?

LenKa [72]

If you are looking for the equation, I’m pretty sure it would be x^2 + 5 + 6. 2 x 3 is 6 and 2 + 3 is 5 so if you factored it out it would be (x + 2) (x + 3). This would mean that your zeroes would be -2 and -3.

If 9:7 is the ratio, there are here 116 more boys than girls how many total students are there

Natali5045456 [20]

Now, let's say there are "b" boys and "g" gals... ok... well, we know there are 116 more boys than gals..... so, if there are "g" gals then there must be "g + 116" boys.

$\bf \cfrac{boys}{girls}\qquad 9:7\qquad \cfrac{9}{7}\implies \cfrac{9}{7}=\cfrac{\stackrel{boys}{g+116}}{\stackrel{girls}{g}}\implies 9g=7g+812
\\\\\\
2g=812\implies g=\cfrac{812}{2}\implies g=\stackrel{girls}{406}$

what's the total class? well is g + b or g + ( g + 116).
