Answer:
f(-5)= 90, g(7)= -3x+4
Step-by-step explanation:
First Solve f(x)
f(x)= 3×^2-3x
Plug in -5 to the x
3(5)^2-3(-5)
f(x)= 90
Then Solve g(x)
g(x)=-3x+4
Plug in the 7 in the x
g(x)=-3x+4
g(x)=17
Devisor is the bottom number
hmm
11.75=11 and 3/4
so times it by 4 to clear denomenator
but do it by top and bottom
23.4/11.75 times 4/4=93.6/47
so times it by 4/4

Answer:
16.65 feet
Step-by-step explanation:
Okay, we have three boards that are each 6.85 feet long. If we cut 3.4 feet off one board, that board has:
6.85
−
3.4
=
3.45
feet left
If we cut off 0.5 feet off another board, that board has:
6.85
−
0.5
=
6.35
feet left
So, if we take our three new boards, the total length of plywood left is:
6.85
+
3.45
+
6.35
=
16.65
feet
Hope this helps!
Answer:
x = 1/3
Step-by-step explanation:
-4(3x − 2) = 6x + 2
Distribute
-12x +8 = 6x +2
Add 12x to each side
12x-12x+8 = 6x+2+12x
8 = 18x+2
Subtract 2 from each side
8-2 = 18x+2-2
6 = 18x
Divide each side by 18
6/18 = 18x/18
1/3 =x
