A constant function is a
function of the form
= b . The slope of a constant function is
Answer:
The slope of the constant function is 0
Step-by-step explanation:
The equation of the constant function is f(x) = b, where b is the y-interceptThe constant function is represented graphically by a horizontal line, the y-coordinates of all points lie on it is bThe slope of any horizontal line is 0 because the difference between the y-coordinates of any two points on the line is 0, then m = 0, so its equation is y = b∵ The equation of the constant function is in the form f(x) = b
∵ The equation of the horizontal line is y = b
∴ f(x) = y
∵ The slope of the horizontal line is 0
∴ The slope of the constant function is 0
We want to get the slope of a constant function, we will see that the slope is equal to zero.
Linear functions:
A general linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
For the case of the constant function we have:
y = b
Notice that we can rewrite this as:
y = 0*x + b
Then is easy to see that the slope of the constant function is equal to 0.

Which of these numbers is four less than a square number?
A 3
B 20
C 37
D 45
Answer:
D
Step-by-step explanation:
You first add 4 to all of the numbers giving you 7, 24, 41, and 49. Only choice D is a perfect square. for reference, 7*7=49
Answer:
45
Step-by-step explanation:
basically what we are trying to find is x + 4= square
for you to understand this better, take eg 5.
5 + 4 = 9
| \
four less than the square number( 9 is the square of 3)
we took the square of 3 and subtracted 4 from it making the result 4 less
12 + 4 = 16
| \
four less than the square number( 16 is the square of 4)
we took the square of 4 and subtracted 4 from it making the result 4 less
understanding that,
a)3
3 + 4 = 7
there is no square root of 7 X
b)20
20 + 4 = 24
there is no square root of 24 X
c)37
37 + 4 = 41
there is no square root of 41 X
d) 45

Slope of dotted/dashed line: -3
Slope of Reflection line: 0.25
Equation of Reflection line: y = 0.25x - 2
Step-by-step explanation:
Slope of dotted line: rise/run. So 3/1 = 3. It is a negative slop because of the way it is facing ( \ ).
Slope of reflection line: rise/run. So 1/4 = 0.25. It is a positive slope ( / ).
Equation of reflection line: y = mx + b
m = slope
b = y-intercept
y = 0.25x - 2

C
(-18, -6), (-3, -6), and (-3, -18)
D
(18, 6), (3, 6), and (3, 18)
Answer:B
Step-by-step explanation:
The new coordinates after dilation and the reflection across the y - axis will be (6, 3), (18, 3) and (6, 18).
What is dilation of a figure?
A dilation is a transformation that enlarges or reduces a figure in size.
Given is figure [A] as shown in the figure which is dilated three times the size and is reflected across the y-axis.
Given are the coordinates of the triangle as -
(-2, 1), (-6, 1) and (-2, 6)
When the image is dilated by K, then each coordinate will become -
(x, y) = (Kx, Ky)
Therefore, the new coordinates will be -
(-6, 3), (-18, 3) and (-6, 18)
Now, in reflection across the y - axis, the coordinates will become (-x, y) from the coordinates (x, y).
Therefore, the final coordinates will be -
(6, 3), (18, 3) and (6, 18)
Therefore, the new coordinates after dilation and the reflection across the y - axis will be (6, 3), (18, 3) and (6, 18).

MUST SHOW ALL WORK WILL MARK BRAINLEST TO WHOEVER ANSWERS CORRECTLY
Answer:
A)
[tex]y=10.25x[/tex]
B)
24 hours
C)
$410
Step-by-step explanation:
We are given that Kelly’s paycheck varies directly with the number of hours she works.
We know that she received $133.25 for 13 hours of work.
Part A)
The standard form for the direct variation equation is:
[tex]y=kx[/tex]
Where k is the constant of variation.
Here, y is the paycheck amount and x is the number of hours Kelly worked.
We know that Kelly received $133.25 for 13 hours of work. Hence, y = 133.25 when x = 13:
[tex]133.25=13k[/tex]
Solve for k:
[tex]k=10.25\\[/tex]
Therefore, our constant of variation is 10.25.
We can substitute this into our equation:
[tex]y=10.25x[/tex]
Therefore, our direct variation equation is:
[tex]y=10.25x[/tex]
Contextually, the equation tells us that Kelly earns $10.25 per hour.
Part B)
Using the equation, we can determine the the number of hours Kelly worked to earn $246. We can substitute 246 for y:
[tex]246=10.25x[/tex]
Solve for x:
[tex]\displaystyle x=\frac{246}{10.25}=24[/tex]
Therefore, x = 24.
Therefore, Kelly must’ve worked 24 hours for her paycheck to be $246.
Part C)
We can use our equation. This time, we will substitute 40 for x and evaluate. Hence:
[tex]y=10.25(40)=\$410[/tex]
So, Kelly will earn $410 for working 40 hours.

this is same as

= [tex](a + b + 5c)(a^2+b^2 +25c^2 -ab -5bc -5ac)[/tex]

Math Scores vs. Hours Spent Studying Science Scores vs. Hours Spent Studying Spelling Scores vs. Hours Spent Studying History Scores vs. Hours Spent Studying
Answer:

Step-by-step explanation:
This is the answer because if you look at all of the other options, then you will see that they have a steeper slope, you could also calculate and find for slope if u are still unsure :) hope this helps
The graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph
What is the slope of a line?The slope of a line is the quotient of the change in the vertical values to the corresponding horizontal values
Check below on how the trend line with the least slope can be determined
From the question, we have:
Line 1: (2.5, 60) and (3.5, 70)Line 2: (0.5, 40) and (3.5, 50)Line 3: (0.5, 80) and (4.5, 90).Line 4: (0.5, 50) and (2, 70).The slope (m) is calculated using:
m = (y₂ - y₁)/(x₂ - x₁)
So, we have:
m₁ = (70 - 60)/(3.5 - 2.5) = 10m₂ = (50 - 40)/(3.5 - 0.5) = 3.3m₃ = (90 - 80)/(4.5 - 0.5) = 2.5m₄ = (70 - 50)/(2 - 0.5) = 13.3The line 3 has the least slope
i.e. m₃ = 2.5
Hence, the graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
10-pound mixture that would sell for $80?
Answer:
4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
Step-by-step explanation:
Let w = wooden block
Let p = plastic bricks
Given the following data;
Price of wooden block per pounds = $5
Price of plastic brick per pounds = $10
*Translating the word problem into an algebraic equation*
For the 10-pound mixture;
[tex] w + p = 10[/tex] .........equation 1
For the $80 mixture;
[tex] 5w + 10p = 80[/tex] ..........equation 2
Solving the linear equation by using the substitution method;
Making w the subject in equation 1:
[tex] w = 10 - p[/tex] .......equation 3
Substituting "w" into equation 2;
[tex] 5(10 - p) + 10p = 80 [/tex]
Simplifying the equation, we have;
[tex] 50 - 5p + 10p = 80 [/tex]
[tex] 50 + 5p = 80 [/tex]
Rearranging the equation, we have;
[tex] 5p = 80 - 50[/tex]
[tex] 5p = 30 [/tex]
[tex] p = \frac {30}{5} [/tex]
p = 6 pounds (For the plastic brick).
To find w;
Substituting "p" into equation 3;
[tex] w = 10 - 6[/tex]
w = 4 pounds (For the wooden block).
