Answer:
y = - [tex]\frac{2}{5}[/tex] x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (5, 2) ← 2 points on the line
m = [tex]\frac{2-4}{5-0}[/tex] = [tex]\frac{-2}{5}[/tex] = - [tex]\frac{2}{5}[/tex]
Note the line crosses the y- axis at (0, 4) ⇒ c = 4
y = - [tex]\frac{2}{5}[/tex] x + 4 ← equation of line
Answer:
y = -2/5 +4
Step-by-step explanation:
Create the equationpoints are :
(0 , 4 ) and ( 5,2)
midpoint = (0 + 5 )/2 and ( 4 + 2 )/2
= (2.5 , 3 )
the gradient = (2 - 4 )/ ( 5 - 0)
= -2/5
now create the equation using both gradient and midpoint
Y - y1 = m (X - x1)
y-3 = -2/5 (x - 2.5)
y = -2/5 x +1 +3
y = -2/5 +4

How is the graph of y=-6x^2-4 different from the graph of y=-6x^2
It is shifted 4 units to the left.
It is shifted 4 units to the right.
It is shifted 4 units down.
It is shifted 4 units up.
Answers
Answer:
Step-by-step explanation:
it is shifted 4 units down.
y=f(x)
y=f(x)+a,a>0
it is shifted a units up .
y=f(x)-a ,a>0
it is shifted a units down.
Final answer:
The graph of y=-6x²-4 is the same as the graph of y=-6x² but shifted 4 units down. This shift is because a constant term (in this case -4) added or subtracted from a function results in a vertical shift of the graph.
Explanation:
The question asks how the graph ofy=-6x²-4 differs from the graph ofy=-6x². This is a situation where we are dealing with vertical shifts in quadratic functions. Looking at the function y = f(x), a subtraction of a constant term outside the function (not multiplying x) results in a vertical shift of the graph. Here, y=-6x²-4 is the same function as y=-6x², but with a vertical shift downwards by 4 units, resulting in the graph being shifted 4 units down.
For clarification and based on transformations, if we had a function f(x) = x² and transformed it to f(x) = x²- 4, the graph would shift vertically down by 4 units. Similarly, the graph of y=-6x², a downward-facing parabola with its vertex at the origin, will be shifted down by 4 units due to the -4 at the end of y=-6x²-4. Therefore, the correct answer is that the graph is shifted 4 units down.
Travis bought a sticker for $2.53 and a belt for $5.68. He then used the rest of his money to buy a pizza. He spent a total of $14.24. How much money did Travis spend on the pizza?
$6.03
$8.21
$8.56
$11.71
Answers
$14.24- $8.21= $6.03
answer is $6.03
Answer:
$6.03
Step-by-step explanation:
Let the amout Travis spent on pizza be reapresented as A.
Travis bought a sticker for $2.53,
Belt = $5.68
Pizza = ?
Total amount of money spent = $14.24
To get the amount spent on pizza , add up amount of everything he bought and equate them to total amount spent
That’s
$2.53 + $5.68 + A = $14.24
$8.21 + A = $14.24
Subtract $8.21 from both sides
$8.21 - $8.21 + A = $14.24 - $8.21
A = $6.03
Travis spent $6.03 on the pizza

Amanda answered all the questions on her math test but got 10 answers wrong. She received 4 points for every correct answer, with no points for wrong answers, and her final score was 76 points.
Step-by-Step Solution
1. Let q represent the total number of questions on the test.
2. The number of correct answers Amanda got is (q - 10).
3. Amanda's score for correct answers can be represented as 4 × (q - 10).
4. According to the problem, her score was 76 points, so we can set up the equation: 4 × (q - 10) = 76.
5. Simplify and solve for q:
4q - 40 = 76
4q = 116
q = 29
Therefore, the total number of questions on Amanda's math test is 29.

Each of the letters of the word MISSISSIPPI are written on a piece of paper and then put into a bag. A piece of paper is drawn at random. What is the theoretical probability of NOT drawing an I?
Answers
The probability of not drawing an I is the number of non-I letters divided by the total number of letters, which is 7/11.
The word MISSISSIPPI has a total of 11 letters, with the following distribution: 4 I's, 4 S's, 2 P's, and 1 M. To find the theoretical probability of NOT drawing an I, we need to consider all the other letters that could be drawn instead. There are 11 - 4 = 7 letters that are not Is. Therefore, the probability of not drawing an I is the number of non-I letters divided by the total number of letters, which is 7/11.

a dog groomer buys 7 packages of treats. Gourmet treats are sold in packs of 2. treats that help clean a dog's teeth are sold in packs of 5. the dog groomer buys 26 treats in all. how many packages of each did she buy?
Answers
Answer:
4 packs of 5
3 packs of 2
Step-by-step explanation:
5•4=20
2•3=6
20+6=26
Let's solve this problem using a system of equations. We'll use two variables:
Let \( x \) be the number of gourmet treat packages (each with 2 treats).
Let \( y \) be the number of dental treat packages (each with 5 treats).
We have two pieces of information that will translate into equations:
1. The dog groomer buys 7 packages in total: \( x + y = 7 \)
2. The dog groomer buys 26 treats in all: \( 2x + 5y = 26 \)
Now, we have a system of two equations with two variables:
\[ \begin{align*}
x + y &= 7 \quad \text{(Equation 1)} \\
2x + 5y &= 26 \quad \text{(Equation 2)}
\end{align*} \]
We will solve this system using the substitution or elimination method. Let's use substitution in this case. We can solve Equation 1 for \( x \):
\[ x = 7 - y \]
Next, we substitute \( 7 - y \) for \( x \) in Equation 2:
\[ 2(7 - y) + 5y = 26 \]
Expanding and simplifying,
\[ 14 - 2y + 5y = 26 \]
Combine the \( y \) terms:
\[ 3y = 26 - 14 \]
\[ 3y = 12 \]
Divide both sides by 3 to solve for \( y \):
\[ y = \frac{12}{3} \]
\[ y = 4 \]
Now that we have \( y \), we can find \( x \) using \( x = 7 - y \):
\[ x = 7 - 4 \]
\[ x = 3 \]
So, the dog groomer bought 3 packages of gourmet treats and 4 packages of dental treats.
To check if the solution is correct, we can plug the values back into the original equations:
Equation 1 (number of packages)
\[ 3 + 4 = 7 \] (Correct)
Equation 2 (total number of treats)
\[ 2(3) + 5(4) = 6 + 20 = 26 \] (Correct)
The solution is correct, and the problem is solved. The dog groomer bought 3 packages of gourmet treats and 4 packages of dental treats.
kasey's school starts at the time shown on the clock. what time does kasey's school start
Answers
While the exact time Kasey's school starts isn't provided, it can be inferred that the common school start time ranges from 8:00 a.m. to 8:30 a.m., based on the information given.
Explanation:The question involves reading a clock to determine what time Kasey's school starts. While the exact time is not provided in the given information, we can infer from various texts that a traditional school start time is typically around 8:00 a.m. In some contexts, like in the case of Jennifer Fuller, a teacher reflects on starting work at 7:45 a.m. which might hint at school starting shortly afterward, likely 8:15 a.m. However, considering the broader perspective given by multiple sources and the push for schools to start no earlier than 8:30 a.m. for teenagers' health, we can surmise that Kasey's school likely starts around 8:00 a.m. to 8:30 a.m., which is a common start time mentioned in the materials provided.
Two cubes have a scale factor of 4:1, what is the ratio of the surface areas of these cubes
Answers
Final answer:
The ratio of the surface areas of the two cubes with a linear scale factor of 4:1 is 16:1, because surface area is proportional to the square of the scale factor.
Explanation:
When working with scale factors in geometry, and specifically with cubes, the ratio of scale factors for linear dimensions affects the surface area and volume in specific ways. If two cubes have a scale factor of 4:1, the ratio of their surface areas is the square of the scale factor. Since the scale factor for the linear dimensions is 4, the ratio of the surface areas will be 42:12, or 16:1.
The surface area of a cube is calculated by multiplying the area of one face (length x width) by 6, as a cube has 6 faces. If one cube has a side four times as long as the other, each of its faces will be 42 times larger because area is a two-dimensional measurement. Thus, the surface area of the larger cube will be 16 times greater than that of the smaller cube, hence the ratio 16:1.

round quesadilla. Which is larger, half of the 10-inch quesadilla or the entire 5-inch quesadilla?
Answers
Answer:
Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla
Step-by-step explanation:
we know that
The area of a circle is equal to
[tex]A=\pi r^2[/tex]
where
r is the radius
step 1
Find the area of the 10 inch-round quesadilla
we have
[tex]D=10\ in[/tex]
[tex]r=10/2=5\ in[/tex]
substitute
[tex]A=\pi (5)^2[/tex]
[tex]A=25\pi\ in^2[/tex]
step 2
Find the area of the 5 inch-round quesadilla
we have
[tex]D=5\ in[/tex]
[tex]r=5/2=2.5\ in[/tex]
substitute
[tex]A=\pi (2.5)^2[/tex]
[tex]A=6.25\pi\ in^2[/tex]
step 3
Which is larger, half of the 10-inch quesadilla or the entire 5-inch quesadilla?
Compare
half of the 10-inch quesadilla is equal to ----> [tex]\frac{1}{2}(25\pi)=12.5\pi\ in^2[/tex]
the entire 5-inch quesadilla ---->[tex]6.25\pi\ in^2[/tex]
therefore
Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla

Azand sold some books at $44 each and used money to buy some concert tickets at $60 each. He had no money left over after buying the tickets. What is the least amount of money he could have earned from selling the books ? What is the least number of books he could have sold ?
Answers
The least amount of money Azand could have earned by selling books is $2640. This is because it would allow him to purchase an exact number of concert tickets without any money left over. Therefore, the least number of books he sold is 60.
Explanation:The subject of your question is Mathematics, specifically an application of simple arithmetic and algebra within the context of real world scenarios. To find out the least amount of money Azand could have earned from selling the books and the least number of books he could have sold, we need to realize one key piece of information: the total money spent on tickets (which is also the total money earned from the books) needs to be a multiple of both $44 (the cost of a book) and $60 (the cost of a ticket).
To find the lowest common multiple you simply multiply the numbers together. This gives $2640. Therefore, the least amount of money Azand could have earned by selling the books is $2640. The least number of books he sold can be calculated by dividing the total money by the cost of each book, $2640/$44, which equals 60. So he sold at least 60 books.
