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

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.

[tex]63 \ cm^2[/tex]
Step-by-step explanation:
The area of a triangle is found using the following formula:
[tex]A = \frac{base * height}{2}[/tex]
The base of our triangle is 21 cm.
The height of our triangle is 6 cm.
[tex]A= \frac{6*21}{2} =3 * 21 = 63[/tex]
Our distance unit is cm, so our area will be in cm squared.

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.

Point P is presently located at the origin. Move P, and observe how the rotated Images change. Be sure that neither the images nor the preimage overlap. Record the distances of the vertices of the prelmage ABC from P. Do the same for the other images. Round all of your answers to the hundredths place.
What can you conclude about your observations in question 4? What happened as you moved p, the center of rotation, about the coordinate plane? How can you extend your discoveries about the vertices to all point that lie on a figure or shape?

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.
Does anyone know how to solve this? I really need help please.
Answer:
See Below
Step-by-step explanation:
angle BAK = 128
Find KAS
180 - 128 = 52
KAS = 52
find BKA and ABK
360 -128 = 232
232/2 = 116
BKA =116
ABK = 116
find AKS
180 - 116 = 64
AKS =64
Now you have KAS and AKS
add together and subtract sum from 360 to find BSK
52 + 64 = 116
360 - 116 =244
Let me know if incorrect, plz.
Hope this helps=)

Determine if the function is one-to-one.
Answer:
No

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.
