Jalen is computing the slope of a line on the graph below. Which statement describes Jalens error?
Jalen computed the raitio in e to change in y
Jalen use the ordered pairs in the wrong order
Jalen made a computational error
Jalen used an ordered pair that is not on the line
The statement which describes Jalen's error is that: A. Jalen computed the ratio of change in x to change in y.
What is a graph?A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Slope, m = Δy/Δx
In this context, we can reasonably infer and logically deduce that the statement which describes Jalen's error is that Jalen computed the ratio of change in x to change in y i.e Δx/Δy, instead of Δy/Δx = (0 - 3)/(-4 - 2).

The 15 members of a team are getting new uniforms. Shirts cost $25
each, shorts cost $30 each, and shoes cost $75 a pair. What is the TOTAL
cost of the new uniforms for ALL of the members?
Answer:
$1,950.00
Step-by-step explanation:
Total cost of shirts = $25 x 15 = $375
Total cost of shorts = $30 x 15 = $450
Total cost of shoes = $75 x 15 = $1,125
Total cost = $375 + $450 + $1,125
= $1,950.00
I need help understanding the question is x+1=-5
Answer:so you have to get x by itself so minus 1 to both sides that would equals x=-6 thats your answer but if it was 2x=-6 then you wound divide until you get x by itself hope this helps but the answer is
x=-6
Step-by-step explanation:
Answer:
I got you!
So x is basically a placeholder for a number. We don't know what that number is, so we just put the letter x so we can make an equation. x can also be shown as a ? or any symbol as long as it consitant throughout the whole equation. for x+1=-5, we are trying to find what number when added to 1 equals -5. Or.... 1+?=-5. We can subtract 1 from each side of the equation to get ?=-6. Or in this case, X=-6!
Solve. Check for extraneous solutions. -∛x+3=0
No Extraneous solution in the equation.
The equation is
-∛x + 3 = 0
To find whether the solution has the extraneous solution or not we need to find the value of x.
∛x = 3
x = 27
Now we have to put the value of x = 27 in the equation
∛27 = 3
3 = 3
Therefore we get to know that there is no extraneous solution to the equation.

Step-by-step explanation:
During one month Andre used 785 gallons of water at his home. There are approximately 3.8 liters in 1 gallon.Which measurement is closest to the number of liters Andre used during this month?
The closest measurement to the number of liters Andre used during the month is 2,983 liters of water.
How is the measurement determined?The measurement of the number of liters used is determined by multiplying the number of gallons of water by the approximate value of 1 gallon in liters.
Using one of the mathematical operations, multiplication, the conversion of the quantity of water from gallons to liters can be computed.
Data and Calculations:The total number of gallons of water used = 785
Conversion of 1 gallon to liters = 3.8 liters per gallon
The total number of liters of water used = 2,983 (785 x 3.8)
Thus, the closest measurement to the number of liters Andre used during the month is 2,983 liters of water.

Evaluate 32+ (6-2) 4-3. (1 point)
The simplified form of the given expression is 45.
The given expression is 32+(6-2)4-3.
An expression in math is a sentence that contains at least two numbers/variables and at least one math operation. The mathematics operators will be addition, subtraction, multiplication and division.
The expression is 32+(6-2)4-3.
Firstly, we will simplify the subtraction which is in the bracket, we get
32+(6-2)4-3=32+(4)4-3
Now, we will simplify the multiplication, we get
32+(6-2)4-3=32+16-3
Further, we will simplify the addition, we get
32+(6-2)4-3=48-3
Furthermore, we will simplify the subtraction, we get
32+(6-2)4-3=45
Hence, the simplified form of the given expression 32+(6-2)4-3 is 45.

What is the constant of 2x+3y+4z+5a+6b
Constants values in the expression 2x+3y+4z+5a+6b are 2,3,4 ,5 and 6.
A constant is a value or number that is consistently the same regardless of how it is expressed. For instance, in the aforementioned figure, where its face value is 36 and 82 respectively, 36 and 82 remain constant. Its worth remains constant.
To broaden our definition, we can say that a constant is something that never changes. Either a single digit or a symbol that denotes a specific number is used. You could substitute a letter like a, b, or c for a constant.
An illustration of a constant term is the mathematical symbol Pi. The word "Pi" refers to a well-known number that can be used alone.

Hayley and Phoebe have a lemonade stand where they sell cups of lemonade for $0.75 a piece. The function p(c)=0.75c represents the profit p(c) that the girls
earn if they sell c cups of lemonade. The girls have 150 cups.
Find the domain and range. Write your answers as compound inequalities.
The domain of the function is given by: 0 ≤ c ≤ 150
The range of the function is given by : 0 ≤ p(c) ≤ 112.5
The range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of domain values.In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).The given statement states that the profit from selling 150 cups of lemonade is denoted by p(c) such that p(c) = 0.75c
Now the girls can sell a maximum of 150 lemonades.
Hence the domain of the values are : 0 ≤ c ≤ 150
at x=0 , p(c) = 0.75 × 0 = 0
at x= 150 , p(c) = 0.75 × 150 = 112.50
Therefore the range of the function is : 0 ≤ p(c) ≤ 112.5

The line passing through point [tex]F[/tex] that is skew to [tex]\overleftrightarrow{EH}[/tex] is [tex]\overleftrightarrow{CF}[/tex] .
Skew lines are two parallel but non-intersecting lines. The two lines that pass through the opposing edges of a normal tetrahedron are a straightforward illustration of a pair of skew lines.
To check if two lines are skew we need to check by following the steps mentioned below:
Step 1: Find lines that do not cross one another.
Step 2: Verify that these line pairs are not also parallel to one another.
Step 3: Check whether these non-intersecting, non-parallel lines are non-coplanar. If the answer is affirmative, the selected pair of lines are skew.
Therefore, the line [tex]\overleftrightarrow{CF}[/tex] passes through point F, the line is not parallel to the line [tex]\overleftrightarrow{EH}[/tex] and is also non-coplanar. Both the lines do not intersect each other.
Hence, [tex]\overleftrightarrow{CF}[/tex] and [tex]\overleftrightarrow{EH}[/tex] are skew lines.

Montserrat can make 4 bracelets in 2 1/4 hours. How many bracelets can she make per hour
Answer: Montserrat bracelets can she make per hour = 0.5625 hours
Step-by-step explanation:
Given data,
Montserrat can make 4 bracelets in 2 1/4 hours.
Let assume Montserrat can make 1 bracelets in x hours.
So,
we can write,
4 ⇒ 2 1/4
1 ⇒ x
Then,
4x = 1 * 2 1/4
4x =1* 9/4
4x = 9/4
x = (9/4)/4
x = 9/16
x = 0.5625 hours.
