Answer:
A=3x^2 -14x -5
Step-by-step explanation:
(x-5)(3x+1)
3x^2 +x -15x -5
3x^2 -14x -5
Answer:
He will need to pay 5.4 Ghana cedis into his educational fund.
Step-by-step explanation:
We need to multiply 4 1/2 by 120 since it is a percentage. We convert 4 1/2 into a decimal which is 4.5. Now, we just need to multiply 120 by 4 1/2 to get an answer of 5.4.
Answer:
-4 = slope
Step-by-step explanation:
Answer:
1: 6 ^ 3
2: Neither
3: 6 ^ 3
4: 6 ^ -3
Step-by-step explanation:
First off, GOOD LUCK IXL IS AHDIOFJDSFS
(Second, I hope I am correct and gotchu, I think I am though, have a nice day!)
<u>Third:</u>
1: 6 ^ 3 If you mutiple it out then the negatives will cancel each other out
2: Right off the bat we can tell it is neither because a 3 times a 3 won't equal a 3.
3: 6 ^ 3 (flip fraction and change sign)
4: 6 ^ -3 (flip fraction and change sign)
2.1x + 4.2y = 14.7 is the same as x + 2y = 7 (divide both sides by 2.1)
-5.7x-1.9y=-11.4 is the same as 3x + y = 6 (divide both sides by -1.9)
Rearrange the first equation to get x = 7 - 2y and substitute into the second equation, 3(7 - 2y) + y = 6, 21 - 6y + y = 6, 5y = 15, y = 3
Substitute y = 3 into the first equation x + 2(3) = 7, x = 1
x = 1 and y = 3
