The table below shows two equations:
Equation 1 |2x - 3| + 5 = 4
Equation 2 15x + 31 – 10 = 3
Which statement is true about the solution to the two equations?
Answer:
First x=-2
Second x= -11.94
Step-by-step explanation:
1 |2x-3|+5=4
2x+3+5=4
2x+8=4
2x=-4
Divide by 2 for both parties
X = -2
Number 2
215x +31-10=3
215x+21=3
215x= -18
Divide by 215 on both sides
X= - 11.94

Louisa has 4 yards of fabric. She uses 2/5 yard of fabric to make a doll dress. How many doll dresses can Louisa make with the fabric? Choose the number line model that shows the answer. A. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts. B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts. C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts. D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Answer:
I believe the answer is D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Step-by-step explanation:
She can make 10 dresses if you split the number line into 20 parts and find 2/5. Therefore, it would then be grouped into 10 parts, each part 2/5ths of a yard.

A sequence is defined by the formula f(n+1)=f(n)−3. If f(4)=22, what is f(1)? 10 13 31 34
Answer:
C:31
Step-by-step explanation:
Considering the given recursive function, it is found that the value of f(1) is of f(1) = 31.
What is the definition of the recursive function?It is given by:
f(n + 1) = f(n) - 3.
Which means that each term is the previous term subtracted by 3, hence:
f(4) = 22, f(3) = 25, f(2) = 28, f(1) = 31.

A rope which is 10.3 centimeters long is cut into 4 pieces of equal length. Write an equation to find the length of
each piece? Use x as the length of each piece of rope.
x - 4 = 10.3 EQUATION
SOLUTION:
x = 10.3 + 4
x = 14.3
Answer: x = 10.3 ÷ 4
Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.
Please write:
1. y=-(x-6)^2+7 vertical compression or stretch
2. y=1/4(x+5)^2 vertical compression or stretch
3. y=4(x+1)^2-6 vertical compression or stretch
Answer:
1. No vertical compression or stretching but will open up downward.
2. 1/4 vertical stretch
3. 4 vertical compression
Step-by-step explanation:
Any time your dealing with vertical stretching or compression it will always be the number before the parentheses.
So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression
2. Is the 1/4 is a vertical stretch
3. 4 is a vertical compression.
Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be.

Describe and correct the error a student made when starting to solve the equation 8 ^ (x + 3) = 2 ^ (2x - 5) 8 ^ (x + 3) = 2 ^ (2x - 5) (2 ^ 3) ^ (x + 3) = 2 ^ (2x - 5) 2 ^ (3x + 3) = 2 ^ (2x - 5) Choose the correct answer below A. The student should have divided both sides by 2 ^ 2 to simplify the expression B. The student did not convert 8 to the correct power of 2 C. The student did not distribute 3 in * (2 ^ 3) ^ (x + 3) x + 3 D.The student should have expressed the initial rational exponent as the sum of two rational exponents ..
Answer:
C. is the correct option
C. The student did not distribute 3 in * (2 ^ 3) ^ (x + 3) x + 3
and x = - 14
Step-by-step explanation:
8 ^ (x + 3) = 2 ^ (2x - 5)
Here is how the student solved the equation
8 ^ (x + 3) = 2 ^ (2x - 5)
8 ^ (x + 3) = 2 ^ (2x - 5)
(2 ^ 3) ^ (x + 3) = 2 ^ (2x - 5)
2 ^ (3x + 3) = 2 ^ (2x - 5) ----- This is where the student made the error.
The student did not distribute 3 in * (2 ^ 3) ^ (x + 3).
This is how to solve the equation
8 ^ (x + 3) = 2 ^ (2x - 5)
8 ^ (x + 3) = 2 ^ (2x - 5)
(2 ^ 3) ^ (x + 3) = 2 ^ (2x - 5)
Then, we will 3 distribute in (2 ^ 3) ^ (x + 3), so that we get
2 ^ (3x +9) = 2 ^ (2x -5)
Since the bases on both sides of the equation are equal, we can equate the powers so that we get
(3x +9) = (2x -5)
Then we will collect like terms
3x - 2x = -5 -9
∴ x = -14
This solution could be better written in this format
[tex]8^{x+3} = 2^{2x-5} \\2^{3} ^{(x+3)} = 2^{2x-5}\\2^{(3x+9)} = 2^{2x-5}\\{(3x+9)} = {2x-5} \\3x-2x= -5-9\\x = -14[/tex]
a. About how far is it from Amarillo to Oklahoma City? Explain your reasoning. b. Driving at a constant speed of 70 miles per hour, will it be possible to make this trip in 3 hours? Explain how you know.
Answer:
They are 260 miles apart. No it would not be possible.
Step-by-step explanation:
If they are 260 miles apart and you drive at a constant speed on 70mph. You will have to 260/70 which = 3.7 or 4 so it would not be possible.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
It is not possible to make this trip in [tex]3[/tex] hours.
By using any geographical tool, such as the local map or you can use internet too to find the distance between Amarillo and Oklahoma City.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Time = \frac{Distance}{Speed}[/tex]
[tex]Time = \frac{260}{70}[/tex]
Time [tex]= 3.714[/tex] hours
So, it is not possible to make this trip in [tex]3[/tex] hours.

Angle XYZ = 2X° and angle PQR = (8X -20)°. If angle XYZ and angle PQR are supplementary, find the measure of each angle. Angle PQR = ?
Answer:
[tex]PQR = 140[/tex]
Step-by-step explanation:
Given
[tex]XYZ = 2X[/tex]
[tex]PQR = 8X - 20[/tex]
Required
Find PQR
Since both angles are supplementary, we have:
[tex]XYZ + PQR = 180[/tex]
This gives:
[tex]2X + 8X - 20 = 180[/tex]
[tex]10X - 20 = 180[/tex]
Collect Like Terms
[tex]10X = 20 + 180[/tex]
[tex]10X = 200[/tex]
Divide through by 10
[tex]X = 20[/tex]
Substitute 20 for X in [tex]PQR = 8X - 20[/tex]
[tex]PQR = 8 * 20 -20[/tex]
[tex]PQR = 140[/tex]

A container holds an unknown number of pints of water. Let p represent this unknown amount. Nari pours three-fourths of this volume into an empty pot. She then adds another 2 pints of water. The pot now holds a total of 11pints of water. Set up and solve an equation to find the value of p.
Answer: 12
Step-by-step explanation:
Let p represent this unknown amount.
Nari pours three-fourths of this volume into an empty pot. This can be written as:= 3/4 × p = 3/4p = 0.75p
She then adds another 2 pints of water and the pot now holds a total of 11pints of water. This means we will add 2 to 0.75p and equate to 11. This will be:
0.75p + 2 = 11
0.75p = 11 - 2
0.75p = 9
p = 9/0.75
p = 12
P equals to 12
This question is based on solving linear equation.Therefore, the answer is 12 pints of total amount of water.
Given:
Nari pours three-fourths of this volume into an empty pot.She then adds another 2 pints of water. The pot now holds a total of 11 pints of water.
Let the unknown amount of pints of water is p.
According to the question,
She pours three-fourths of this volume into an empty pot. This can be written as:
[tex]\dfrac{3}{4}\times p= \dfrac{3}{4} p = \bold{0.75p}[/tex]
She add on 2 pints of water to 0.75 p in pot, then it becomes total of 11 pints of water.
In ,mathematically expressed as,
[tex]\begin{alligned}0.75p+2&=11\\0.75p&=11-2\\0.75p&=9\\p&=\frac{9}{0.75}\\\bold{p&=12}\end{alligned}[/tex]
Therefore, there is total amount of 12 pints water.

Solve 2(4x+2)=4x-12(x-1)
Answer:
x = 1/2
Step-by-step explanation:
Answer:
x = 0.5
Step-by-step explanation:
2(4x+2)=4x-12(x-1) (by PEDMAS, we deal with the parentheses first by using the distributive property)
4x(2)+2(2)=4x+ x(-12) -1 (-12)
8x + 4 = 4x - 12x +12 (simplyfy each side)
8x + 4 = - 8x +12 (add 8x to both sides)
8x + 4 + 8x = 12
16x + 4 = 12 (subtract 4 from both sides)
16x = 12 - 4
16x = 8 (divide both sides by 16)
x = 8/16
x = 0.5
