The local fitness center is running two different monthly payment options to attract new customers. The options are shown below.
What is the rate of change for the plans and at what number of visits would the plans cost the same amount?
Answer: The rate is increasing upwards, if that is what you were asking?
Step-by-step explanation: Let me know if you need anything else, please :)
The rate of change for payment option 1 is 1 and for payment option 2 is 0.25.
At 4th visit the cost of both the plans will be same.
What is the slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.
We know the slope m = (y₂ - y₁)/(x₂ - x₁).
Payment option 1 has two points (0, 2) and (2, 4).
Slope(m₁) = (4 - 2)/(2 - 0).
Slope(m₁) = 2/2
Slope(m₁) = 1.
4 = 2(1) + b.
b = 2.
y = x + 2.
Payment option 2 has,
$0.25 every visit is $(1/4) and it is the rate of change or the slope.
y = 0.25x + 5.
The number of visits when the cost will be equal is when we'll equate these two equations,
x + 2 = 0.25x + 5.
x - 0.25x = 5 - 2.
0.75x = 3.
x = 3/0.75.
x = 4.
At 4 visits the cost of each plan will be the same.

A line passes through point A(12,18). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.
PLEASE! PUT THIS IN POINT SLOPE FORM!
Answer:
y - 18 = -1.5(x - 12)
Step-by-step explanation:
A = (12, 18)
B=(1.25(12), 0.75(18)) = (15, 13.5)
Find slope: m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5
Point slope form: y - y1 = m(x - x1)
Using point A as (x1, y1)
y - 18 = -1.5(x - 12)
complete the statement to describe the expression (a+b+c)(d+e+f).
the expression consists of ? factors, and each factor contains ? terms.
Answers:
the expression consists of 2 factorseach factor has 3 terms==============================================
Explanation:
The two factors are (a+b+c) and (d+e+f). A factor is a part of multiplication. So in general if we multiply x and y, then x and y are factors to lead to the product x*y.
The expression a+b+c has three terms. Each term is separated by a plus sign.
The expression d+e+f also has three terms.

QRST is a rectangle. If RT = 4x - 16 and SQ = x + 5, find the value of x.
Answer:
The value of x is 7.
Step-by-step explanation:
Both RT and SQ are diagonals of the rectangle, so they have the same measure.
We have that:
[tex]RT = 4x - 16, SQ = x + 5[/tex]
Since they are equal:
[tex]4x - 16 = x + 5[/tex]
[tex]4x - x = 5 + 16[/tex]
[tex]3x = 21[/tex]
[tex]x = \frac{21}{3}[/tex]
[tex]x = 7[/tex]
The value of x is 7.

Nori had 2 1/12 bags of apples. He used 1 5/12 bags of apples to make pies How many bags of apples does Nori has left
Answer:
3 1/2
Step-by-step explanation:
Answer is 8/12.
Mixed number Fraction:
A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
(Here),
Nori had [tex]2\frac{1}{12}[/tex] bags of apples.
Given, he used [tex]1\frac{5}{12}[/tex] bags of apples.
Nori left = [tex]2\frac{1}{12}[/tex] - [tex]1\frac{5}{12}[/tex]
=> (25 / 12) - (17 / 12)

What is the distance between -6 and 4 on a number line? Show your work.
Answer:
10
Step-by-step explanation:
First you add 6 to get to 0 on the number line. Then you add 4 to get to your final destination which is 4. You add them together to get 10.
Write the ratio 3/5 to 6 as a fraction in simplest form
Answer:
1/10
Step-by-step explanation:
To convert a ratio to a fraction, you divide the number on the left by the number on the right. This gets you (3/5)/6. When dividing fractions by whole numbers, you need to convert the whole number to a fraction. I converted 6 to 6/1, so that gave me (3/5)/(6/1). You then multiply the top number by the bottom number to get the numerator of the answer, and the middle 2 numbers multiplied is the denominator. The answer is (3x1)/(5x6), or 3/30, which can be simplified to 1/10.

What word describes the slopes of the line
Answer:
Positive
Step-by-step explanation:
There are a couple ways we can go about this.
First, we can see that as x increases, so does y, so that means its positive
For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place
If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.
We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.

Find the cost of 1 slice for Cheese A:
Set up a proportion: [tex]\frac{3.59}{10} = \frac{x}{1}[/tex] Cross multiply, then divide: 3.59 × 1 = 3.59, 3.59 ÷ 10 = 0.359So, the cost of 1 slice of Cheese A is $0.359Find the cost of 1 slice for Cheese B:
Set up a proportion: [tex]\frac{5.12}{16} = \frac{x}{1}[/tex] Cross multiply then divide: 5.12 × 1 = 5.12, 5.12 ÷ 16 = 0.32So, the cost of 1 slice of Cheese B is $0.32Make a conclusion:
Because $0.32 is less than $0.359, Cheese B is the better buy.
