b) no, the equation isn't a linear function as it takes the form of a parabola (x^2-bx).
Q5) y=x+6, y= x^2+6 and y=2x+6 go through the point of (0,6). This is because, if you substitute 0 for x in all the three equations, y is always equal to 6.
Q6) the line is a linear function because it is a straight line that has a slope and a y intercept. To figure out the equation of the line, you have two points, (-2,0) and (0,3). To no the gradient, you do 3-0 divided by 0+2, which is 3/2. Then, you choose on random point and substitute it in y=mx+b
3= 3/2*0+b
So you get 3=b
So, the equation of the line is y= 3/2x+3

O (4,-4)
Answers
Answer:
(-4,-8)
Step-by-step explanation:
The solution to the system of equations is,
⇒ (- 4, - 8)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expressions are,
⇒ y = 1/2x - 6
⇒ x = - 4
Now, We can simplify the expression for y as;
⇒ y = 1/2x - 6
Put x = - 4;
⇒ y = 1/2 × - 4 - 6
⇒y = - 2 - 6
⇒ y = - 8
Thus, The solution to the system of equations is,
⇒ (- 4, - 8)

Which rational number is also an integer
A. - 86 / 6
B. - 65/13
C. 43/5
D. 70/25
Answers
This is because 65/13 = 5 when using a calculator or long division. There are no fractional or decimal parts to the result 5, so 5 is an integer.
Something like 86/6 = 14.333 approximately showing the result is not an integer. The same applies to choice C and choice D as well.

what is the solution of the system of equations shown above?
Answers
The value of x=2 and y=1.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3x+2y=8
5x+2y=12
Now, solving both using method of Elimination Method
3x - 5x = 8-12
-2x= -4
x = -4/ -2
x= 2
and, 3x+ 2y = 8
3(2) + 2y = 8
6 + 2y = 8
2y = 8-6
2y = 2
y = 2/2
y= 1
Hence, the value of x=2 and y=1.

You need to make at least 360 wraps for a party. You can make 9 wraps per minute.
How long will it take you to make the number of wraps you need?
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the inequality.
Answers
Answer:
It will take 40 minutes for me to make the 360 wraps that I need.
9x ≥ 360 ⇒ x ≥ 40
Step-by-step explanation:
I have to make at least 360 wraps for a party.
I can make 9 wraps per minute.
So, it will take minutes for me to make the 360 wraps that I need.
If I work for x minutes to make wraps, then I will be able to make 9x wraps.
So, the inequality that models the given condition is
9x ≥ 360
⇒ x ≥ 40 {Dividing both sides by 9}
Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

Kimberly is deciding between two cell phone plans. The first plan has a $50 sign-up
fee and costs $20 per month. The second plan has a $30 sign-up fee and costs $25 per
month. After how many months will the costs be the same for the two phone plans?
Answers
Answer:
2month and 2 weeks
Step-by-step explanation:
We are told that the first plan has a $50 sign-up
fee and costs $20 per month.
let the number of months be x, and the total cost be y
y=20x+50---------1
The second plan has a $30 sign-up fee and costs $25 per
let the number of months be x, and the total cost be y
y=30x+25---------2
Equate the two equations we have
20x+50=30x+25
solve for x, collect like terms
50-25=30x-20x
25=10x
divide both sides by 10
x= 25/10
x=2.5 months
x= 2month and 2 weeks

A 20% discount on $50 takes us to $40. A 25% discount on the $40 takes us to 30%.
We can also do a 4% discount to bring us to $48, followed by a 62.5% discount, to get to $30.
A rectangle is located on a coordinate plane. If the ordered pair (t, u) represents a vertex of this rectangle, which algebraic representation describes the effect of translating the rectangle 8 units up and 3 units left?
Answers
Answer: (t,u) -> (t-3, u+8)
Step-by-step explanation: Up is the y value and left is the x value.
In the point ( t,u) t is the x value and u is the y value.
Moving to the left, you subtract the value and moving up you add the value.
The answer would be (t, u) → (-t – 3, u + 8)
