It depicts horizontal linear equation, as the slope is 0.
The slope of horizontal lines is zero. Consequently, m = 0 in the slope-intercept equation y = mx + b. Y = b, where b is the y-coordinate of the y-intercept, results in the equation.
The y-coordinate of every point on a horizontal line is the same. The line's equation is y=b if two points share the same y coordinate, b. The point (0,b) is the y-intercept of the horizontal line y=b. Horizontal lines don't have an x -intercept other than the line y=0.
A horizontal line is a line that is perpendicular to the x-axis. Because the value of x never changes, the graph of a relation of the form x = 5 is a line parallel to the y-axis.

After placing his order, Samuel realized he could have saved money if he, instead, ordered 2 posts with words and pictures. Let y represent Samuel's savings, in dollars, and let x represent the number of posts. Which equation could be used to determine the amount of money Samuel could have saved if he ordered 2 posts with words and pictures, instead of his original order? A y = 5x – 5B. y = 5.r + 65C y = -5r + 25D y = 2
x = Number of posts
y = samuel's savings
If he order 2 posts with words and pictures:
y = 2(10) + 35 = 55
If he order 2 posts with words only and 2 posts with pictures only.
y = 2(5) + 2(10) + 5 + 25 = 10 + 20 + 5 + 25 = 60
Therefore, he could have save 5 dollars

The Hike 4 Life company manufactures hiking boots. The production facility has foxed costs of $400 a day and the cost of making 1 pair of boots is $4.75. Which of the following equations
represents the daily production cost based on the number of pairs of boots manufactured each day?
The equation that represents the daily production cost based on the number of pairs of boots manufactured each day is C(x) = 4.75x + 400.
What are linear equations?
Linear equations are a subset of first order equations. Linear equations are defined for lines in the coordinate system. One homogeneous variable of degree one constitutes a linear equation in one variable (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.
Given, the daily production cost (in $) = C(x)
The number of pairs of boots manufactured = x
The cost of making a pair of boots = $ 4.75
The fixed cost of production each day = $ 400
Thus, net cost of making 'x' boots added to the daily fixed production cost will give the daily production cost.
Therefore, C(x) = 4.75x + 400, is the correct equation.

Answer:
First option is correct.
Step-by-step explanation:
Normally, Pete's dad deposits $25 into his bank account every week.
Now, he wants to deposit x extra dollars for 8 weeks. So, the total deposits for these 8 weeks will be:
8*(25 + x)
He wants to keep the total deposits above 500. So
8*(25 + x) > 500
Now we solve the inequality similarly to how we would solve an equality.
8*(25 + x) > 500
200 + 8x > 500
8x > 500 - 200
8x > 300
x > 300/8
x > $37.50

Customer 1 buys 2 hamburgers and 4 drinks, and his total is $13.00. Customer 2 buys 3 hamburgers and 7 drinks, and his total comes out as $21.00. PART A. You want to buy 8 drinks and 9 hamburgers for you and your friends. How much do you expect to pay?PART B. Show your work or explain how you got your answer.
Answer:
[tex]\text{Total= \$43.5}[/tex]Step by step explanation:
To solve this situation we can create a system of linear equations, with the given information for the customers:
Let x be the price for each hamburger
Let y be the price for each drink
[tex]\begin{gathered} 2x+4y=13\text{ (1)} \\ 3x+7y=21\text{ (2)} \end{gathered}[/tex]To solve for x and y. We can use the substitution method, which consists of isolating one variable in one of the equations and substitute it into the other.
Let's isolate y in (1):
[tex]\begin{gathered} 4y=13-2x \\ y=\frac{13}{4}-\frac{2}{4}x \end{gathered}[/tex]Now, substitute it into equation (2).
[tex]3x+7(\frac{13}{4}-\frac{2}{4}x)=21[/tex]Solve for x:
[tex]\begin{gathered} 3x+\frac{91}{4}-\frac{7}{2}x=21 \\ -\frac{1}{2}x+\frac{91}{4}=21 \\ -\frac{1}{2}x=21-\frac{91}{4} \\ -\frac{1}{2}x=-\frac{7}{4} \\ x=\frac{7\cdot2}{4} \\ x=\frac{7}{2}=\text{ \$3.5 } \end{gathered}[/tex]With the x-value, we can substitute it into the equation (1) to find the price for each drink:
[tex]\begin{gathered} y=\frac{13}{4}-\frac{2}{4}(3.5) \\ y=\frac{13}{4}-\frac{7}{4} \\ y=\frac{6}{4}=\text{ \$1.5} \end{gathered}[/tex]Therefore, the price for each hamburger is $3.5 and for each drink is $1.5.
Now, if we want to buy 8 drinks and 9 hamburgers:

The weekly repair cost Y for a machine has a probability density function given by f(y)=3(1−y)^2, 0
Using integrals, the 90th percentile of the given probability distribution is of $53.58.
What is the 90th percentile of the distribution?The amount exceeded only 10% of the time is the 90th percentile of the distribution, which is the value of p for which:
[tex]\int_0^p f(y) dy = 0.9[/tex]
The integral represents the cumulative density function of the distribution, which is the reason why we use it to find the 90th percentile of the distribution.
The function is given by:
f(y) = 3(1 - y)²
Hence the integral is calculated as follows:
[tex]\int_0^p 3(1 - y)^2 dy[/tex]
Applying the integral of the power of y rule, along with the substitution, it is found that:
[tex]\int 3(1 - y)^2 dy = -(1 - y)^3[/tex]
Hence:
[tex]\int_0^p 3(1 - y)^2 dy = -(1 - y)^3|_{y = 0}^{y = p}[/tex]
Applying the Fundamental Theorem of Calculus, considering the value of the definite integral, it is found that:
-(1 - p)³ + 1 = 0.9
-(1 - p)³ = -0.1
(1 - p)³ = 0.1
Applying the cube root to both sides:
1 - p = 0.4642.
p = 1 - 0.4642
p = 0.5358.
This amount is in hundredths of dollars, hence the 90th percentile of the given probability distribution is of $53.58, as 0.5358 x 100 = $53.58.

1/8=?/4 how does this get solved?
Answer: ? = 1/2
Step-by-step explanation:
Your question is a bad example, so let me come up with one.
2/8 = 1/4
This is done by dividing both the numerator and denominator by the same value: 2/8 / 2/2
or
2/2 = 1, 8/2 = 4
We now have 1/4
or 9/36
What can we divide 36 by, 9 by? We need to divide by both for it to work.
9/3 = 3
36/3 = 12
3/12 But we can divide this again
3/3 = 1
12/3 = 4
1/4, we could also have divided 9/36 by 6/6 to get 1/4
For 1/8 to get ?/4, we do
8/? = 4
? = 1/2
, so the answer is 1/2/4 = 1/2*4 = 1/8
