Slope intercept - What is the slope of y=4-2x?
Answers
The slope of the line y = 4 - 2x is -2.
The equation given is in slope-intercept form, which is y = mx + b, where m represents the slope of the line. In this case, the equation is y = 4 - 2x. Comparing it to the slope-intercept form, we can see that the slope, represented by m, is -2.
The slope indicates the rate at which the line rises or falls as x increases. A slope of -2 means that for every unit increase in x, the corresponding value of y decreases by 2 units. It also indicates that the line has a negative slope, meaning it slants downwards from left to right.
To further illustrate, if we consider two points on the line, (0, 4) and (1, 2), we can calculate the slope using the formula:
slope = (y₂ - y₁) / (x₂ - x₁)
Plugging in the values, we get:
slope = (2 - 4) / (1 - 0) = -2 / 1 = -2
Therefore, the slope of the line y = 4 - 2x is -2.

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)

Kelly has a pool in her backyard, and she wants to build a fence around the entire area. Kelly's backyard is 14 meters wide and 15 meters long. It costs $6.63 per meter to install a wooden fence. How much would it cost to put a wooden fence around Kelly's backyard?
Answers
Answer:
$384.54Step-by-step explanation:
Dimensions of the backyard is 14 m by 15 m
The length of the fence is the perimeter of the backyard.
P = 2(l +w)P = 2(15 + 14) = 2(29) = 58 mOne meter of the fence costs $6.63
Cost of the entire fence is:
58*$6.63 = $384.54Answer:
perimeter of backyard=2(15+14)=58m
it cost
1m=$6.63
58m=$6.63×58=$384.54
therefore it cost
$384.54 to put a wooden fence around Kelly's backyard.

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

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
