Step-by-step explanation:
just see if this is right
f (x)+g (x)
f (x)= -3x^2 - 1---------(1)
g(x)= 4x - 2------------(2)
(1)+(2)
-3x^2 - 1+ 4x - 2
-3x^2+4x - 3
Answer:
.95 cents
Step-by-step explanation:
19 divided by 20 is .95 cents
3x + y = 10
x - 4y = -1
Multiply the 2nd equation by -3
-3x +12y = 3
Add the 1st equation to the 3rd equation:
13y = 13
Divide both sides by 13:
y = 1
Answer: A) 1
Answer:
9 : 3
Step-by-step explanation:
To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...
63 / 7 = 9
Therefore 63 : 21 = 9 : 3
