PLEASE PLEASE HELP PLEASE
Answer:
x = -3
Step-by-step explanation:
2(4x + 6) = 8x + 12
3(x - 1) = 3x -3
8x + 12 = 3x - 3
5x = -15
x = -3
Answer:
x=-3
Step-by-step explanation:
2(4x+6)=3(x-1)
8x+12=3(x-1)
8x-3x+12= -3
8x-3x=-3-12
5x=-3-12
5x=-15
x=-3

Hello!
[tex]\large\boxed{2x - 8 = 7 - 3x \text{ and } 4(x - 1) = x + 5}[/tex]
We can go through each equation to solve:
1.
x + 3 = 4(x - 1) + 2
Distribute the coefficient outside of the parenthesis:
x + 3 = 4(x) + 4(-1) + 2
Simplify:
x + 3 = 4x - 4 + 2
x + 3 = 4x - 2
Subtract x from both sides:
3 = 3x - 2
Add 2 to both sides:
5 = 3x
Divide both sides by 3:
5/3 = x. This is not the answer.
2.
2x - 8 = 7 - 3x
Add 3x to both sides:
5x - 8 = 7
Add 8 to both sides:
5x = 15
Divide both sides by 5:
5x/5 = 15/5
x = 3. This is an answer.
3.
3(x + 2) = 14 - x
Distribute:
3(x) + 3(2) = 14 - x
3x + 6 = 14 - x
Add x to both sides:
4x + 6 = 14
Subtract 6 from both sides:
4x = 8
Divide both sides by 4:
4x/4 = 8/4
x = 2. This is not an answer.
4.
4(x - 1) = x + 5
Distribute:
4x - 4 = x + 5
Subtract x from both sides:
3x - 4 = 5
Add 4 to both sides:
3x = 9
Divide both sides by 3:
3x/3 = 9/3
x = 3. This is an answer.
5.
5 - 2(x + 1) = x
Distribute:
5 - 2x - 2 = x
Simplify:
3 - 2x = x
Add 2x to both sides:
3 = 3x
Divide both sides by 3:
3/3 = 3x/3
x = 1. This is not an answer.
6.
6(x - 4) = 2x
Distribute:
6x - 24 = 2x
Subtract 6x from both sides:
-24 = -4x
Divide both sides by -4:
-24/(-4) = -4x/(-4)
x = 6. This is not an answer.
Answer:
2x - 8 = 7 - 3x
4(x -1) = x + 5
Step-by-step explanation:
2) 2x - 8 = 7 - 3x
2x + 3x - 8 = 7
5x - 8 = 7
5x = 7 + 8
5x = 15
x = 15/5
x = 3
4) 4(x -1) = x + 5
4x - 4 = x + 5
4x - 4 - x = 5
3x - 4 = 5
3x = 5 + 4
3x = 9
x = 9/3
x = 3

Over what interval(s) is the function strictly linear? Look at the picture. Don't Answer If You Don't Know What The Answer Is Please. Will Mark Brainliest.
Answer:
The answer is given by option c.
Step-by-step explanation:
Linear function:
The graphic of a linear function is a straight line.
In this question:
We have a straight line for x between -2 and 0, so in this interval the function is linear.
For x between 0 and 2, the function is a curved line, so not linear in this interval.
We also have a straight line for x between 2 and 4, so in this interval the function is linear.
So it is linear in the following intervals: -2 < x < 0, 2 < x < 4, so the answer is given by option c.

Lin's family has traveled 25 miles which is only 20% of the trip.
How far is the whole trip?
a.
5 miles
c. 100 miles
b.
125 miles
d. 250 miles
Please hurry
Answer: 125 miles
Step-by-step explanation:
We know that 25 miles is 20% of the trip.
20% is 1/5 of 100, so that means we will multiply the number of miles driven by the denominator of the fraction.
25 × 5 = 125 miles
The answer to the question is 125 miles.

The volume of a cube is related to the area of a face by the formula V = A^3/2What is the volume of a cube whose face has an area of 100 cm??
helppp!!
Answer:
[tex]\huge\boxed{1000 \ \text{cm}^3}[/tex]
Step-by-step explanation:
There are two ways we can solve this equation.
A) Using the formula providedThe formula provided states that the volume of a cube based on the area of one of it's faces will be [tex]a^{\frac{3}{2}}[/tex], a the area of one face. Since we know the area of one face, we can substitute that inside the equation.
[tex]100^{\frac{3}{2}}[/tex]
It's important to note that when we have a number to a fraction power, it's the same as taking the denominator root of the base to the numerator power.
So - [tex]100^{\frac{3}{2}}[/tex] becomes [tex]\sqrt{100^3}[/tex]
[tex]100^3=1000000[/tex] [tex]\sqrt{1000000}=1000[/tex]Therefore, the volume of this cube will be [tex]1000 \ \text{cm}^3[/tex]
B) Using prior knowledge about cubesWe can additionally use prior knowledge to find the volume of this cube.
We know that the area of a square will be [tex]s^2[/tex], where s is the length of a side. We also know the formula to find the volume of a cube from it's side length is [tex]s^3[/tex].
Since we know that one face is 100, we can make an equation - [tex]s^2=100[/tex]
[tex]\sqrt{s^2}=\sqrt{100}[/tex] [tex]s=10[/tex]Now that we know the value of s, we can plug it into the volume formula, [tex]s^3[/tex].
[tex]10^3[/tex] [tex]10 \cdot 10 \cdot 10[/tex] [tex]1000[/tex]So the volume is [tex]1000 \ \text{cm}^3[/tex].
Hope this helped!

:)
help I need help pleaseee
Answer:
The perimeter of a rectangle is the sum of twice the length and twice the width. If the perimeter is at least 48 cm, then the minimum perimeter is 48 cm.
Let width = x
Let length = x + 4
Perimeter = 48
We can set an inequality for perimeter using the variables.
2x + 2(x + 4) ≥ 48
Solve for x.
2x + 2x + 8 ≥ 48
4x + 8 ≥ 48
4x ≥ 40
x ≥ 10
Substitute this value of x into the variable to get your width and length.
width = 10 cm
length = 14 cm
