Answer:
The hourly cost for parking
Step-by-step explanation:
The equation is given in the slope intercept form; which means the "3" in front of the x means the cost for parking is 3 and x will be the amount of hours; just like the slope m in the equation y = mx + b
PLS HELP! ILL MARK BRAINIEST! what is the x and y intercept for this equation?

A book publisher counted the words on each page of a series of books. They found that the number of words per page followed a normal distribution with a mean of 265 words and a standard deviation of 25 words.
What percentage of the pages contain fewer than 215 words?
Answer:
The answer is 2.5%
Step-by-step explanation:
Took test on edmentum and made 100%.
2.2% percentage of the pages contain fewer than 215 words.
The normal distribution is defined as a probability distribution that is symmetric about the mean, indicating that data close to the mean are more systematic in occurrence than data distant from the mean. In pictorial form.
The number of words per page in the book is normally distributed, Normal distribution is given as,
[tex]z = \frac{x-\mu}{\sigma}[/tex]
Where, x = number of words per page., µ = mean, σ = standard deviation
From given, µ = 265 words , σ = 25 words
Probability for the number of pages in the book is less than 265 words,
P( x < 215)
For, x = 25,
z = (215-265)/25 = -2
From the normal distribution table, the probability of the z score is 0.022
The percent of pages in the book that are less than 215 words in length is 0.022 × 100 = 2.2%.
Thus, 2.2% percentage of the pages contain fewer than 215 words.

What is a system of equations?A system of equations is a set or collection of two or more equations with the same variables. The common solutions are the intersecting points of the equations. The number of equations and unknowns affects the existence and uniqueness of the solution. A system of equations can be classified similarly to single equations.
Given that, the graph given shows a system of equations,
We know that, the solution of the system of equations, is given by the point where the lines intersect,
So, here the lines intersect, at (3, 2)
Therefore, the x-coordinate is 3
Hence, the x-coordinate of the solution to the system of equations is 3.

One of the zookeepers solved to find Bernard's speed
when he is, healthy using the equation:
x - 41.5 = 13.5.
The other Zookeeper said that to solve for Bernard's
speed when he is healthy, they must use the equation:
41.5 + 13.5 = x.
Which zookeeper is correct? Explain.
Answer:
Well both zookeepers are correct but the second zookeepers answer was more accurate.
Step-by-step explanation:
The first zookeeper gave the equation :
[tex]x - 41.5 = 13.5[/tex]
So , In order to find Benards speed which is denoted as x , we would still have to collect like terms to isolate x.
The second zookeeper gave the equation :
[tex]41.5 + 13.5 = x[/tex]
In this equation the zookeeper had already isolated x so, only simple addition was needed to find Bernard's speed.
This equation is easier to solve.

find the perimeter of the shaded figure.
Answer:
38
Step-by-step explanation:
Count the unit squares for each side, starting from the left it's 7, 10, 7, 2, 2, 6, 2, and 2
Now add them together:
7 + 10 + 7 + 2 + 2 + 6 + 2 + 2 = 17 + 9 + 8 + 4 = 26 + 12 = 38
Answer: 38 units
Step-by-step explanation: Perimeter is asking for the total length of all the sides that make up a figure. The top border is 10 units, the two outer sides are 7 each (14 in total), if you add all the downward facing edges you get another 10 units, and the two inside sides are 2 units each (4 in total).
10+14+10+4 = 38

What is the equation of the line that passes through the point (4.11) and is perpendicular to the line with the following equation? OA. y = -x + 14 O B. - r - 15 OD. & 1 + 8
Answer:
[tex]y = x +7[/tex]
Step-by-step explanation:
Given
[tex]Point\ (x_1,y_1) = (4,11)[/tex]
Perpendicular to [tex]y = -x + 14[/tex]
Required
Determine the line equation
An equation has the form
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison with [tex]y = -x + 14[/tex]
[tex]m = -1[/tex]
Because the line is perpendicular to [tex]y = -x + 14[/tex], the following relationship exists
[tex]m_1 = \frac{-1}{m}[/tex] i.e. the condition for perpendicularity
Where m1 is the slope of the equation that passes through [tex]Point\ (x_1,y_1) = (4,11)[/tex]
So, we have:
[tex]m_1 = \frac{-1}{-1}[/tex]
[tex]m_1 = 1[/tex]
The line equation is then calculated using:
[tex]y - y_1 = m_1(x - x_1)[/tex]
Where
[tex]m_1 = 1[/tex]
[tex]Point\ (x_1,y_1) = (4,11)[/tex]
So, we have:
[tex]y - 11 = 1(x - 4)[/tex]
[tex]y - 11 = x - 4[/tex]
Add 11 to both sides
[tex]y - 11+11 = x - 4+11[/tex]
[tex]y = x - 4+11[/tex]
[tex]y = x +7[/tex]

A town has a population of 3000 and grows at 4% every year. To the nearest tenth of a year, how long will it be until the population will reach 4700?
Answer:
14.2 years
Step-by-step explanation:
The town grows 4% (0.04) every year.
3000 x 0.04 = 120, so the town gains 120 people every year.
The town needs 1700 more people to get to 4700.
So, 4700/120= 14.1666666667
That rounds up to 14.2 years.

B)
x + 3
C)
x – 2
D)

If we factor x^3-3x^2, the result is x^2(x-3).
Answer:
D
Step-by-step explanation:
Given
x³ - 3x² ← factor out x² from each term
= x²(x - 3) ← in factored form
with one of the factors being x - 3 → D

Taking two random points from the graph to find the slope:
(-1, -6) and (1, -5)Use slope formula: m = (y2 - y1)/(x2 - x1)
m = (-5 - (-6))/(1 - (-1)) = 0.5The line in slope-intercept form is (y = mx + b)
y = 0.5x - 5.5or
