Which is the graph of the system of equations y = 3x + 6 and y = 3x +1?
Answers
Answer:
See the picture attached. The purple line is y=3x+6 and the red line is y=3x+1.
Step-by-step explanation:
When graphing lines, start with the y-intercept and then use the slope to plot points to help you draw the line.
The equations are in y=mx+b form, where mx is the slope and b is the y-intercept. To get the points, plug in a number where x is. Whatever result you get is the y coordinate for that number.
For example, on the graph in the picture 3(1)+1 = 4. Using that, you would plot the point (1,7).
Hope that makes sense!

A function rule takes an input, and converts it into an output, y, by decreasing twice the input by 4. what is the output for this rule when the input is 5?
Answers
Answer:
when the input = 4Then the output = 6Step-by-step explanation:
It is stated that a function rule takes an input, and converts it into an output, y, by decreasing twice the input by 4.
Let 'x' be the number
Decreasing twice the number 'x' by 4 = 2x-4
Now,
Given the input x = 5
As the output will decrease twice the input (x=5) by 4
Thus, the output = 2(5)-4 = 10-4 = 6
Therefore,
when the input = 4Then the output = 6The point A (10,15) was dilated to become point A’ (4,6). What was the scale factor?
Answers
========================================================
Explanation:
Preimage = A = (10, 15)
Image = A' = (4, 6)
Divide the x coordinates of the image over preimage
4/10 = 0.4 is the scale factor
Or you could do the same for the y coordinates

Based on the given equation of b -4/6=b/2, the value of the variable b, can be found to be -2
What is the variable?The variable can be found by solving the equation through the operations of mathematics.
First, cross-multiply:
b -4/6 = b/2
b - 4 = 6b / 2
After cross-multiplying, collect like terms:
b - 4 = 3b
b - 3b = 4
-2b = 4
b = 4 / -2
b = -2

The variables x and y vary inversely. Use the given values to write an equation relating x and y. x=7/2 y=3/5
Answers
Answer:
x = 21/10yStep-by-step explanation:
If the variables x and y vary inversely, this is expressed as;
x ∝ 1/y
x = k/y
k is the constant of proportionality
Given;
x = 7/2 and y = 3/5
Substitute;
7/2 =k/(3/5)
Cross multiply
k = 7/2 * 3/5
k = 21/10
Substitute the value of k into the formula;
x = k/y
x = (21/10)/y
x = 21/10 * 1/y
x = 21/10y
Hence the equation relating x and y is x = 21/10y

A clothing store is running an offer on men's shirts. When two shirts are bought at regular price, the third shirt is 50% off. Jeremy decided to buy three shirts for his brother using the offer. The regular price for a shirt is $36.00. Based on a tax rate of 7.50% that is applied after the discount, Jeremy paid a total of $ 100 for three shirts, including tax.
Answers
Answer: $96.75
Step-by-step explanation:
Regular price is $36 and the third shirt will come at a 50% discount.
Total price for the 3 shirts is;
= 36 + 36 + (36 * 50%)
= $90
The total after-tax is;
= 90 * ( 1 + tax rate)
= 90 * ( 1 + 7.50%)
= $96.75
I am unsure what the question is but the total amount that Jeremy should pay is $96.75.

The equation f(x)=3x can be written as x^3=k. Find the value of k
Answers
After solving the equation we get the value of k as ₋3, and also proved that the function is odd function.
Given the equation is f(x) =x³₋(k₊3) x²₊3x
also we know that the f(x) is an odd function, then by definition we write
f(₋x) = ₋f(x)
f(₋x) = (₋x)³ ₋ (k ₊ 3)(₋x)² ₊ 3(₋x)
= ₋ [x³ ₋ (k ₊ 3)x² ₊ 3x] = ₋x³ ₊ (k ₊ 3)x² ₋ 3x
(₋x)³ ₋ (k ₊ 3)(₋x)² ₊ 3(₋x) = ₋x³ ₊ (k ₊ 3)x² ₋ 3x
₋x³ ₋ kx² ₋ 3x² ₋ 3x = ₋x³ ₊ kx² ₊ 3x² ₋ 3x
₋kx² ₋ 3x² = kx² ₊ 3x²
2kx² ₊ 6x² = 0
2k + 6 = 0
k = -3
Therefore, k has the result of reducing f(x) to x³ ₊ 3x. When we examine this function to check if it's an odd function, we see that
(₋x)³ ₊ 3(₋x) = ₋x³ ₋ 3x = ₋ [x³ ₊ 3x]
Hence the value of k is ₋3 and the function is an odd function.

Answers
The polynomial 9x^2 + 4 is equivalent to (3x+2i)(3x-2i). The answer is A.
Polynomials are algebraic expressions that consist of variables and coefficients where arithmetic operations can be performed.
A polynomial is expanded if no variable appears within parentheses and all like terms have been combined.
To expand a polynomial, multiply its factors (often by using the distributive property) or perform the indicated operations. Then combine all like terms.
Expanding each of the options provided using FOIL method:
a) (3x+2i)(3x-2i)
= 9x^2 - 2ix + 2ix - 4i^2
= 9x^2 - 4i^2 *(i^2 = -1) note that i is an imaginary number and i squared is equal to -1
= 9x^2 - 4(-1)
= 9x^2 + 4
b) (3x+2)(3x-2)
= 9x^2 + 6x - 6x - 4
= 9x^2 - 4
c) (3x + 2i)^2
= 9x^2 + 6ix + 6ix + 4i^2 *(i^2 = -1)
= 9x^2 + 12ix - 4
d) (3x + 2)^2
= 9x^2 + 6x + 6x + 4
= 9x^2 + 12x + 4
Hence, the polynomial 9x^2 + 4 is equivalent to (3x+2i)(3x-2i). The answer is A.

Answers
Answer:
$29,700 and $79,200
Step-by-step explanation:
Step one:
given
The selling price of the house is $396,000
The commission rate is 7.5% for the real estate agency
The commission rate for the agent is 20%
Step two:
1. How much did the agency make on the house?
This amount is 7.5% of $396,000
= 7.5/100*396,000
= 0.075*396,000
=$29,700
2. How much did the agent earn in commission?
This amount is 20% of $396,000
= 20/100*396,000
= 0.2*396,000

Answers
The value of x is 5.
Given that, m∠VUT = 175° , m∠VUJ = 17x-3 and m∠JUT = 17x+8.
The angle where two rays meet is represented as vertex.
Each and every vertex , where two rays meet have some angle between them.
The symbol that represents angle is, “∠”.
Here, you can deal with the angle and find the value of x by just equating the given equations upon the given angle m∠VUT = 175° .
we get,
m∠VUT = m∠VUJ + m∠JUT
175 = 17x-3 + 17x+8
175 = 34x + 5
175-5 = 34x
170 = 34x
170/34 = x
x = 5.
Therefore, the value of x is 5.

If we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.
What is a Discrete variable?A discrete variable is one whose value can be determined by counting. A continuous variable is one whose value can be determined through measurement. A random variable is one whose value is the numerical result of a random phenomenon. The possible values of a discrete random variable X are countable. As an example, It is a type of Discrete variable if we asked people their age and you collected it as 5, 6, 10, 11, 15, 16, 20, 21, 25, 26, and older. There are two types of quantitative variables: discrete variables and continuous variables. Counts are represented by discrete variables (e.g. the number of objects in a collection).

You are designing a rectangular playground on your scale the verticals of the rectangle are (6,3), (6,5) and (8,3). What are the coordinates of the fourth vertex
Answers
Answer:
The coordinates of the fourth vertex are (8,5)
Step-by-step explanation:
We need to take note that a rectangle is a shape that has 4 sides, with two of them of equal length.
It will also help if we can visualize the points on the graph.
We are given the location of three of the four vertices. These are (6,3), (6,5) ,and (8,3). Let the 4th Vertice be (x,y)
The length of the triangle can be obtained by subtracting the y-coordinates of the vertices.
(6,3) - (6,5)
This will be +3 and +5
5-3 =2
Therefore, the length of the triangle is 2 units on the left side.
Recall that the length of the left side has to be equal to the length of the right side.
Therefore
y-3 =2
y = 5
We will repeat the same process to get the x-coordinate from the breadth
Breadth = 8-6 =2
x-6 =2
x=8
Hence the x = 8
Therefore, the coordinates of the fourth vertex are (8,5)
