did my math but I know you need it quick so sorry for brief answer
Answer:
The number is 5
Step-by-step explanation:
Let x be the number
3x+5+x = 25
Combine like terms
4x+5 = 25
Subtract 5 from each side
4x+5-5 = 25-5
4x = 20
Divide by 4
4x/4 = 20/4
x = 5
Answer:
-66
Step-by-step explanation:
- 13, ____, -119
first, find the common difference:
-13 - (-119) = 106
next, divide 106 by 2:
= 53
so, the common difference is 53.
now, subtract 53 from -13:
-13 - 53 = -66

Answer:
Step-by-step explanation:
y = -4x^2 + 4x + 6
Factor out the leading coefficient:
y = -4(x^2 - x) + 6
Complete the square:
y = -4(x^2 - x + (½)^2) + 4(½)^2 + 6
= -4(x-½)^2 + 7
