Perform the operation (x^2+8x+8)+(-10x^2+5x)
Answer:
Step-by-step explanation:
(x^2+8x+8)+(-10x^2+5x) = (x^2-10x^2) + (8x+5x) + 8
= -x^2 +13x + 8
Answer:
-9x^+13x+8

Write an equation of a line with the given slope and y-intercept.
m = (4)/(5), b = 2
A. y= (4)/(5)x - 2
B. y= (4)/(5)x + 2
C. y= (5)/(4)x + 2
D. y= 2x + (4)/(5)
Answer:
B. y= (4)/(5)x + 2

What is the GFC for 80 and 96
Answer:
16
Step-by-step explanation:
Greatest common factor (GCF) of 80 and 96 is 16. We will now calculate the prime factors of 80 and 96, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 80 and 96.

Answer:
3.9x+0.8y
Step-by-step explanation:
4x−5.2y+6y+7.9x−8x
Combine −5.2y and 6y to get 0.8y.
4x+0.8y+7.9x−8x
Combine 4x and 7.9x to get 11.9x.
11.9x+0.8y−8x
Combine 11.9x and −8x to get 3.9x.
3.9x+0.8y
It can also be converted to fraction form:
[tex]\frac{4y}{5}+\frac{39x}{10} = 3.9x+0.8y[/tex]

Answer:
AY = 4.8YD = 2.4Step-by-step explanation:
Corresponding sides of the triangles are ...
ΔFUN . . . ΔDAY
UF = 10 . . . AD = 6
FN = 4 . . . DY
NU = 8 . . . YA
Corresponding sides are proportional, so we have ...
DY/4 = AD/UF = 6/10
DY = 4(0.6) = 2.4
and
YA/8 = 6/10
YA = 8(0.6) = 4.8
The side lengths are ...
AY = 4.8, YD = 2.4
