Answer:
Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Which of the following is a rational number?
Answer:
B.)
Step-by-step explanation:
A rational number is a number with no repeating decimals or decimals that go on “forever” like pi. An expample of a rational number is 2 where 2.3333333... is not a rational number. Pi isn’t a rational number either since forth there is no known end to that.
So, when solved:
A.) = 1.58113883... (irrational)
B.) = -8 (rational)
C.) = 8.94427191... (irrational)
D.) = 3.794733192... (irrational)

Which of the following is a vertical stretch of the
parent function f(x)=x^2
y=4x^2
y=1/4+x^2
y=(1/4x)^2
y = x^2-4
The expression "[tex]y = 4x^2[/tex]" is a vertical stretch of the parent function f(x) = [tex]x^2[/tex].
What is the functions?
Functions are mathematical relations that describe the relationship between inputs (often called "input values" or "arguments") and outputs (often called "function values" or "results").
The vertical stretch of the parent function f(x) =[tex]x^2 \\[/tex] can be identified by the coefficient multiplied with the squared term.
Among the given options:
y = [tex]4x^2[/tex] - This is a vertical stretch of the parent function f(x) = [tex]x^2[/tex] by a factor of 4, which means the graph of the function is stretched vertically by a factor of 4.y =[tex]1/4 + x^2[/tex] - This is a vertical shift and addition of a constant to the parent function f(x) = [tex]x^2,[/tex] but not a vertical stretch.y = [tex](1/4x)^2[/tex] - This is not a vertical stretch of the parent function f(x) = [tex]x^2[/tex]. It involves a reciprocal and squaring operation on x, but not a vertical stretch.y = [tex]x^2 - 4[/tex] - This is a vertical shift and subtraction of a constant from the parent function f(x) = [tex]x^2[/tex], but not a vertical stretch.Hence, the correct option that represents a vertical stretch of the parent function f(x) =[tex]x^2[/tex] is y = [tex]4x^2[/tex] (Option 1).

Ben bought a white plastic shelf that was 6.35 feet long. He also bought a brown plastic shelf that was 2.085 feet long. How much-combined feet of shelving did Ben buy?
Answer:
combined feet of shelving = 8.435 feet
Step-by-step explanation:
To find the combined feet of shelving, we simply add the two lengths of the shelvings:
1. white plastic shelf = 6.35 feet long
2. brown plastic shelf = 2.085 feet long
combined feet of shelving = 6.35 + 2.085 = 8.435 feet
You are baking a cake, and the recipe calls for 3/8 of a cup of flour and 1/2 of a cup of sugar. What is the total amount of flour and sugar, as a reduced fraction?
Answer:
[tex]\frac{7}{8}[/tex]
Step-by-step explanation:
To find the total amount of flour and sugar, you have to find a common denominator for the two fractions and then add them together.
[tex]\frac{1}{2}[/tex] multiplied by 4 equals [tex]\frac{4}{8}[/tex].
Now that the fractions both have a common denominator of 8, we can add them together:
[tex]\frac{3}{8}[/tex] + [tex]\frac{4}{8}[/tex] = [tex]\frac{7}{8}[/tex]
The total amount of flour and sugar is [tex]\frac{7}{8}[/tex]
Hope this helps :)

Name the type of factoring (DoPS, GCF, Trinomials, factoring by parts, factoring with a leading coefficient)
Answer:
1) (x - 9)(x + 2) ==> trinomials
2) (s + z) (3m - 2n) ==> factorising by parts
3) (x + 2)(5x + 3) ==> factorising with a leading coefficient
4) 9y²(3y² - 2) ==> GCF
5) (4m - 12)(4m + 12) ==> DoPS
Step-by-step explanation:
1). Find multiples of -18 that add up to -7
Multiples of -18 : (only one number can be negative, because positive*negative = negative)
1, 18 or 3, 6 or 2, 9
Only one pair adds up to -7 which is -9 + 2
Hence ==> (x - 9)(x + 2)
2). Find the common things between the terms and factorise it out
3m(s + z) - 2n(s + z)
Since the terms inside the brackets are the same, you simplify it to:
(s + z) (3m - 2n)
3). Multiply the first coefficient with the last coefficient: 5(6) = 30
Find two numbers that multiply to 30 and add up to the middle coefficient -13.
Multiples of 30 are: 1, 30 or 2, 15 or 3, 10 or 5,6, but only one pair would add to -13 and that is 3 and 10
So the next step is to write it in this form: 5x² + 10x + 3x + 6
Factorise: 5x(x + 2) + 3(x + 2)
(x + 2)(5x + 3)
4). Find the greatest common factor within 27y⁴ and 18y², which is 9y²
9y²(3y² - 2)
5). Square root each number: √16 = 4 and √144 = 12
(4m - 12)(4m + 12)
what is the solution for 2x-5=7
Answer:
x = 12
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
1. Add 5 to both sides.
2x = 7 + 5
2. Simplify 7+5 to 12.
2x = 12
3. Divide both sides by 22.
x = 12/2
4. Simplify 12/2 to 6

Here A = 121 , then
s² = 121 ( take the square root of both sides )
s = [tex]\sqrt{121}[/tex] = 11

A line with a slope of 3 passes through (2,5). Which choice is an equation of this line?
Answer:
y=3x-4
Step-by-step explanation:
a slope of 3 means that the equation will definitely start like this
y=3x +/- b
to find b, substitute the coordinates given, so
5=3 x 3 +/- b
5=9 +/- b
5-9=b
-4=b
so the equation would be
y=3x-4

line a has a slope of -4/3 and line b has a slope of -3/4 are both lines perpendicular.
Answer:
No they are not perpendicular.

No they are not because they are both line b is still negative.
In order for them to be perpendicular is if the slopes were like this....
-4/3x and 3/4x
or
4/3x and -3/4x
