Answer:
(-5, 3)
Step-by-step explanation:
x = -5
-5x - 10y = -5
Subsitute for x = -5
-5(-5) - 10y = -5
25 - 10y = -5
subtract 25 from both sides
-10y = -30
divide both sides by -10
y = 3

The constant of proportionality (k) tells you how steep the graph of a proportional relationship is. TRUE or FALSE
A proportional relationship has a constant rate of change.
The given statement is true.
Step-by-step explanation:
A proportional relationship has a constant rate of change. We need to tell if this statement is true or false
A proportional relationship is given by equation:
where y is dependent variable while x is independent variable and k is constant of proportionality
The constant of proportionality is constant for all the values of y and x.
So, A proportional relationship has a constant rate of change.
The given statement is true.
The constant of proportionality (k) tells you how steep the graph of a proportional relationship is TRUE.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Let's consider a proportional relationship
y∝ x
y = kx
k = y/x
Now the value of y directly depends on upone k.
So, changing k will change the steepness of the line.
Hence "The constant of proportionality (k) tells you how steep the graph of a proportional relationship is TRUE".

The pair of points (-4, y) and (5, 7) lie on a line with slope . What is the value of y? You must show all of your work to receive credit
The slope of a line is given by the ratio of the rise to the run of the line.
The value of, y is 4
Reasons:
The given points on the line are; (-4, y), and (5, 7)
The slope of the line, = [tex]\dfrac{1}{3}[/tex]
Required:
To find the value of y
Solution:
The formula for the slope is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) = (-4, y)
(x₂, y₂) = (5, 7)
Which gives;
[tex]Slope, \, m =\dfrac{7-y}{5-(-4)} = \dfrac{7-y}{5+4} =\dfrac{1}{3}[/tex]
3·(7 - y) = 1·(5 + 4) = 9
21 - 3·y = 9
3·y = 21 - 9 = 12
[tex]y = \dfrac{12}{3} = 4[/tex]

Determine whether each equation is a linear equation. Write yes or no. If yes, write the equation in standard form. 12x = 7y - 10y
Answer and Step-by-step explanation:
This equation is linear because the slope is changing at a constant rate.
Write in standard form:
Standard form on an equation is written like so: Ax + By = C
First combine the y-values.
12x = -3y
Now add 3y to both sides of the equation.
12x + 3y = 0 <-- This is the answer (equation) in standard form.

Step-by-step explanation:
to find the area of a square: base times height, we know that all sides of a square are the same. So, 11*11
=121, the answer is 11
Answer:
11 in.
Step-by-step explanation:
The canvas has the shape of a square.
The area of a square is the side times the side, but since in a square, all sides have equal lengths, then the area of a square is the square of the side.
You are given the area. You need to find the side.
The area is the square of the side, so the side is the square root of the area.
side = √area
side = √(121 in.²)
side = 11 in.

b. Solve the system using the inverse that is given for the coefficient matrix.
PLEASE HELP WILL GIVE A LOT OF POINTS!!
a) The linear system as a matrix equation in the form AX= B as
[tex]\left[\begin{array}{ccc}-1&1&1\\0&-2&-1\\2&1&0\end{array}\right][/tex] [tex]\left[\begin{array}{c}x\\y\\z\end{array}\right][/tex] = [tex]\left[\begin{array}{c}0\\-2\\4\end{array}\right][/tex]
b) The solution set is {x = 2, y = -4, z = -2}.
Given that A⁻¹ = [tex]\left[\begin{array}{ccc}-1&1&1\\2&-2&-1\\-4&3&2\end{array}\right][/tex],
To find the matrix equation in the form AX = B, multiply both sides of the equation by A⁻¹:
A⁻¹(A⁻¹X) = A⁻¹B
X = A⁻¹B
Therefore, the linear system as a matrix equation in the form AX = B is:
[tex]\left[\begin{array}{ccc}-1&1&1\\0&-2&-1\\2&1&0\end{array}\right][/tex] [tex]\left[\begin{array}{c}x\\y\\z\end{array}\right][/tex] = [tex]\left[\begin{array}{c}0\\-2\\4\end{array}\right][/tex]
2. The given system of equations can be represented as:
A = [tex]\left[\begin{array}{ccc}-1&1&1\\0&-2&-1\\2&1&0\end{array}\right][/tex]
X = [tex]\left[\begin{array}{c}x\\y\\z\end{array}\right][/tex]
B = [tex]\left[\begin{array}{c}0\\-2\\4\end{array}\right][/tex]
Using the given inverse of A:
A⁻¹ = [tex]\left[\begin{array}{ccc}-1&1&1\\2&-2&-1\\-4&3&2\end{array}\right][/tex]
Multiply A⁻¹ by B to solve for X:
[tex]X = A^{(-1)} B[/tex]
[tex]\left[\begin{array}{c}x\\y\\z\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}-1&1&1\\2&-2&-1\\-4&3&2\end{array}\right][/tex] [tex]\left[\begin{array}{c}0\\-2\\4\end{array}\right][/tex]
Performing the matrix multiplication:
| x | = | (-1)(0) + (1)(-2) + (1)(4)| | 2 |
| y | = | (-2)(0) + (3)(-2) + (2)(4)| | -4 |
| z | | (2)(0) + (-2)(-2) + (-1)(4)| | -2 |
Therefore, the solution set is {x = 2, y = -4, z = -2}.

Answer:
Option D
Step-by-step explanation:
Given the inequality statement: 5 + 8x < 3(2x + 4):
We must solve for the solution of the given inequality statement.
First, distribute 3 into the parenthesis:
5 + 8x < 3(2x + 4)
5 + 8x < 6x + 12
Next, subtract 6x from both sides:
5 + 8x - 6x < 6x - 6x + 12
5 + 2x < 12
Then, subtract 5 from both sides:
5 - 5 + 2x < 12 - 5
2x < 7
Divide both sides by 2 to solve for x:
[tex]\displaystyle\mathsf{\frac{2x}{2}<\:\frac{7}{2}}[/tex]
[tex]\displaystyle\mathsf{x<\:\frac{7}{2}}[/tex]
Since [tex]\displaystyle\mathsf{\frac{7}{2}}[/tex] = 3.5, and that the inequality symbol is "<," then it means that [tex]\displaystyle\mathsf{\frac{7}{2}}[/tex] or 3.5 is not included as an endpoint. This corresponds to an empty circle on the 3.5 mark on the number line, pointing towards the left (indicating that the values must be less than 3.5).
Therefore, the correct answer is Option D.
4x+2=2(x+6)
HELP PLEASE
12
Hope it helps!!!!!!!
Answer:
x = 5
Step-by-step explanation:
Let's solve your equation step-by-step.
4x+2=2(x+6)
Step 1: Simplify both sides of the equation.
4x+2=2(x+6)
4x+2=(2)(x)+(2)(6)(Distribute)
4x+2=2x+12
Step 2: Subtract 2x from both sides.
4x+2−2x=2x+12−2x
2x+2=12
Step 3: Subtract 2 from both sides.
2x+2−2=12−2
2x=10
Step 4: Divide both sides by 2.
[tex] \tt \: \frac{2x}{2} = \frac{10}{2} [/tex]

Lucy bakes 135 gingerbread cookies and sells them in boxes of 6
how many full boxes will she have ?
how many cookies will she have left over ?
Answer:
22 boxes
5 cookies left
Step-by-step explanation:
135 / 6 = 22.5
Lucy will have 3 cookies left over that won't fit into any full boxes. To find how many full boxes Lucy will have, we can divide the total number of cookies (135) by the number of cookies in each box (6).
Number of full boxes = Total number of cookies / Number of cookies in each box
Number of full boxes = 135 cookies / 6 cookies per box
Number of full boxes = 22.5
Since Lucy cannot have a fraction of a box, she will have 22 full boxes of gingerbread cookies.
To find how many cookies she will have left over, we can find the remainder after dividing the total number of cookies by the number of cookies in each box.
Number of cookies left over = Total number of cookies % Number of cookies in each box
Number of cookies left over = 135 cookies % 6 cookies per box
Number of cookies left over = 3
