Answer:
6x^2 + 4x
Step-by-step explanation:
g(x) + f(x)
= -8x^2 - 3x + 5 + 2x^2 + 7x - 5
= -8x^2 + 2x^2 - 3x + 7x + 5 - 5
= - 6x^2 + 4x
Answer:
I think you divide by 17 - 3 + 8 and then square root that by 7 and then you probably get the answer
Answer:
20 Questions
Step-by-step explanation:
If 15 is 60% of the total number, you can divide 15 by 60 so you can find 1% of the total amount of questions.
15/60=0.25
0.25*100=25 questions.
Deon only got 80% percent right, which can be multiplied.
25*0.8=20
Hope this helped!
Answer:
The equations which represents the situation are
1) 2Y+X=5 and
2) 5X-Y=3
Step-by-step explanation:
Given X= Smaller number and Y = larger number
Therefore the equation for the statement," twice a number added to a smaller number is 5" is 2Y+X=5
and the equation for the statement,"the difference of 5 times the smaller number and the larger number is 3" is 5X-Y=3
Thus the equations which represents the situation are
1) 2Y+X=5 and
2) 5X-Y=3
