Can someone explain what the answer is to this and how? Thank u!!!
Sloan [31]
The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)

Kameron has a combination of quarters and nickles in his wallet. The number of nickels is three times the number of quarters he
Aleksandr-060686 [28]

Answer:

Kameron has 5 quarters in his wallet

Step-by-step explanation:

Let

x----> the number of nickels

y----> the number of quarters

remember that

1 nickel=$0.05

1 quarter=$0.25

we know that

x=3y -----> equation A

0.05x+0.25y=2

Multiply by 100 both sides

5x+25y=200

Simplify

x+5y=40 -----> equation B

Substitute equation A in equation B

(3y)+5y=40

8y=40

y=5 quarters

x=3(5)=15 nickels

What is the slope of the line represented by:<br><br> 5x-12y = 24
blagie [28]

Answer:

5/12

Step-by-step explanation:

5x - 12y = 24

~Subtract 5x to both sides

-12y = 24 - 5x

~Divide -12 to everything

y = -2 + 5/12x

~Reorder

y = 5/12x - 2

Slope is represent by "m" in slope intercept form [ y = mx + b ]. As we can see m = 5/12 from the given information.

Best of Luck!
