-4(-3x - 8) - 34 Simplify.
Answer:
12x-2
Step-by-step explanation:
-4(-3x - 8) - 34
distribute
12x+32-34
add like terms
12x-2
Answer:
[tex]12x-2[/tex]
Step-by-step explanation:
[tex]-4(-3x-8)-34[/tex] (Distribute the -4)
[tex]12x+32-34[/tex] (Subtract)
[tex]12x-2[/tex]
And if you want to find x.
[tex]12x-2=0[/tex] (Add 2 on both sides)
[tex]12x=2[/tex] (Divide by 12 on both sides)
[tex]x=\frac{2}{12}= \frac{1}{6}[/tex]

Answers and Step-by-step explanations:
9: (4/6) (-5/8)
This is just multiplication of fractions, so all you need to do is multiply both numerators by eachother and both denominators by eachother. Assuming that only the 5 is negative, (this is just an assumption since it's not clear which one is, or you can do the 8,) You get -20/48, since 4 x (-5) = -20, and 6 x 8 = 48. Simplify and you get -5/12.
10: (3/4) (-1/5)
Multiply the numerators, (3 and -1), and the denominators, (4 and 5,) to get -3/20. This is the lowest it can be simplified to, so therefore your answer is -3/20.
11. (-1/8) (-6/7)
Multiply -1 and -6 to get 6, (since two negatives make a positive.) Multiply the denominators, (8 and 7,) to get 56. This maks 6/56, which simplifies to 3/28.
12. (-4/9) (1/5)
Multiply the numerators, (-4 and 1,) to get -4. Multiply the denominators (9 and 5,) to get 45. Your answer is -4/45.

F(x) = 3 x 2 − 3 x − 6 The domain of a the function f(x) is { -10, -1, 1, 5 }. What is the range of the relation?
Answer:
{324, 0, -6, 54}
Step-by-step explanation:
Given that F(x) = 3x² − 3 x − 6 If the domain of a the function f(x) is { -10, -1, 1, 5 }.
To get the range, we will find f(x) for all the domains
at x = -10
f(-10) = 3(-10)²-3(-10) - 6
f(-10) = 3(100)-3(-10) - 6
f(-10) = 300+30-6
f(-10) = 330-6
f(-10) = 324
at x = -1
f(-1) = 3(-1)²-3(-1) - 6
f(-1) = 3(1)-3(-1) - 6
f(-1) = 3+3-6
f(-1) = 6-6
f(-1) = 0
at x = 1
f(1) = 3(1)²-3(1) - 6
f(1) = 3(1)-3(1) - 6
f(1) = 3-3-6
f(1) = 0-6
f(1) = -6
at x = 5
f(5) = 3(5)²-3(5) - 6
f(5) = 3(25)-3(5) - 6
f(5) = 75-15-6
f(5) = 60-6
f(5) = 54
Hence the range of the relation are {324, 0, -6, 54}

Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:
x=5
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−12=−4x+23
Step 1: Add 4x to both sides.
3x−12+4x=−4x+23+4x
7x−12=23
Step 2: Add 12 to both sides.
7x−12+12=23+12
7x=35
Step 3: Divide both sides by 7.
7x
7
=
35

the perimeter of a rectangle is 52 cm. The length of the rectangle can be represented by (x.+5) and its width can be represented by (3x-7) what are the dimensions of this rectangle?
Answer:
Length=11
Width=11
Step-by-step explanation:
P (perimeter) is 52 so
2(x+5)+2(3x-7)=52
then
2x+10+6x-14=52
8x-4=52
8x=48
x=6
so
If Brian took the same test and received a score of 80 % how many questions did he get right? ( hint the test is out of 20 points )
Answer:
16
Explanation:
First you convert
80
%
into a decimal which is
.80
then you multiply it by
20
.
.80
×
20
=
16
We multiply it by
20
because that's our total and by
.80
because that's the amount that we got correct. Had it been
100
%
then that would mean we got every question right.
