Answer:
You can identify the parent function by making the equation into its simplest form.
Step-by-step explanation:
Remove all transformations from the equation (such as plus/minus signs, constants, and extra terms in the equation).
ex. y= -3x^2+15
The parent function would be y=x^2 after removing everything.

2a + 2b = c for b
Solve for b
2a + 2b = c
Subtract 2a from both sides
2b = -2a + c
Divide both sides by 2
b = -a + (c/2)

D = <-2, 10>Step-by-step explanation:
Domain is from x to x.
You can use a ruler to determine it:
Put ruler perpendicular to X-axis at the left end. Move the ruler slowly along X-axis to the right.
When the ruler touch the graph there the x is the beginig of the domain.
Move along to the right. When the ruler touches end of graph there the x is end of the domain.
The filled dot means < >, and the empty dot means ( ).
Which rules define the function graphed below?
y = x; y = 5
y = x + 2; y = 5
y = x; x = 5
y = x + 2; x = 5
Answer:
B) y=x+2; y=5
Step-by-step explanation:
The rules that define the graphed function are y = x + 2; y = 5
How to determine the rule of the function?The function is a piecewise function
There are two lines on the graph.
The first line has the following points
(0,2) and (3,5)
Express 2 and 5 as a sum of 2
(0,0 + 2) and (3, 3 + 2)
This means that the y value is the sum of 2 and the x value.
So, we have:
y = x + 2
The other line has a constant value of 5 for all x values
So, we have:
y = 5
Hence, the rules that define the graphed function are y = x + 2; y = 5

3x-4=2x+1
hello there fair mate
Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
3x - 4 = 2x + 1
Step 2: Solve for x
Subtract 2x on both sides: x - 4 = 1
Add 4 on both sides: x = 5
Answer:
x=5
Step-by-step explanation:
3x-4=2x+1----> you subtract 2x on both sides---->x-4=1 -----> then add 4 on both sides and you get---> x=5. Hope it helped.
600 ÷ 300 hey answers
Answer:
2
Step-by-step explanation:
I hope this helps you :)
Answer:
2
Step-by-step explanation:
Anything divided by 2 is half of itself. So 600 ÷ 300 would technically be 300. But in division we count the amount of times a number can go into the other number. So 600 divided by 300 is 2.
547 and 14 and 7658 - 7000 = 658 - blank = 98 -98 = 0 what is the answer
Solution :
7658 - 7000 = 658 - blank
658 = 658
So here, blank is 0.
547 - 7000 = 658 - blank
-7111 = 658 - blank
Blank = 7769
14 - 7000 = 658 - blank
- 6986 = 658 - blank
Blank = 7644

A slope is also known as the gradient of a line. The points that would be on lines that represent a unit rate greater than the one represented in the table are the first three points.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
The slope of the function that the table represents is 2.2.
Also, the slope of the different points and the origin will be shown on the points that would be on lines that represent a unit rate greater than the one represented in the table are the first three points.
Hence, the points that would be on lines that represent a unit rate greater than the one represented in the table are the first three points.

What are the solutions of the equation x4 – 5x2 – 36 = 0? Use factoring to solve. x = ±2 and x = ±3 x = ±2i and x = ±3 x = ±2 and x = ±3i x = ±2i and x = ±3i
Answer:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
Step-by-step explanation:
So we have the equation:
[tex]x^4-5x^2-36=0[/tex]
Let's let u equal x² so:
[tex]u^2-5u-36=0[/tex]
Factor. We can use -9 and 4. So:
[tex]u^2+4u-9u-36=0[/tex]
From the first two terms, factor out a u.
From the last two terms, factor out a -9. So:
[tex]u(u+4)-9(u+4)=0[/tex]
Grouping:
[tex](u-9)(u+4)=0[/tex]
Zero Product Property:
[tex]u-9=0 \text{ or } u+4=0[/tex]
On the left, add 9. On the right, subtract 4:
[tex]u=9\text{ or } u=-4[/tex]
Substitute back u:
[tex]x^2=9\text{ or } x^2=-4[/tex]
Take the square root:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
And we're done!
