At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 from this account for her contact lenses. After 3 months she has $255 left in her account.
Write an equation in slope-intercept form to represent the relationship between the time that has passed and the amount of money left in Monica's account. Let x represent the time in months and y represent the amount of money remaining in the account.
Answer:
An equation in the slope-intercept form is:
[tex]y = 15x+210[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the rate of change or slope and b is the y-intercept
Given
Let x represent the time in months Let y represent the amount of money remaining in the account.Given that every month Monica withdraws $15 from this account for her contact lenses
so, the rate of change or slope = m = 15Given that after 3 months she has $255 left in her account.
i.e. (3, 255)
substituting [tex]m = 15[/tex], [tex]x = 3[/tex] and [tex]y = 255[/tex] in the slope-intercept form to determine the y-intercept
[tex]y = mx+b[/tex]
[tex]255 = 15(3) + b[/tex]
switch sides
[tex]15(3) + b = 255[/tex]
[tex]45 + b = 255[/tex]
[tex]b = 255 - 45[/tex]
[tex]b = 210[/tex]
Thus, the y-intercept b = 210
Now, substituting [tex]m = 15[/tex] and [tex]b = 210[/tex] in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y = 15x+210[/tex]
Hence, an equation in the slope-intercept form is:
[tex]y = 15x+210[/tex]can someone help me with this problem

Make the following statement an equations (3,-3) m=3
Answer:
We conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:
[tex]y=3x-12[/tex]The graph of the line is also attached.
Step-by-step explanation:
Given
The point (3,-3)The slope m = 3Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line (x₁, y₁) is the pointsubstituting the values m = 3 and the point (x₁, y₁) = (3,-3)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-3\right)=3\left(x-3\right)[/tex]
Apply rule: -(-a) = a
[tex]y+3=3\left(x-3\right)[/tex]
subtract 3 from both sides
[tex]y+3-3=3\left(x-3\right)-3[/tex]
simplify
[tex]y=3x-12[/tex]
Therefore, we conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:
[tex]y=3x-12[/tex]The graph of the line is also attached.

What is the rate of change for the linear relationship modeled in the table? (4 points)
x y
-1 10
1 9
3 8
5 7
negative one over two
0
one over two
2
Answer:
-1/2
Step-by-step explanation:
In a linear relationship, the rate of change of one variable with respect to the other is constant. When we talk about change, we're looking for a difference of values.
If we look at the first and second rows, the change in x is 1 - (-1) = 2, while the change in y is 9 - 10 = -1. Usually we refer to these changes as Δx and Δy (read like "delta-x" and "delta-y"), and the rate of change is the number we get by dividing one of these by the other.
The rate of change we're used to seeing, sometimes called the slope, is Δy/Δx. So, using the values we've already found:
[tex]\Delta{x}=2\\\Delta{y}=-1\\\Delta{y}/\Delta{x}=-1/2[/tex]

The purple shape is a dilation of the black shape. What is the scale factor of the dilation
Answer:
Scale factor = 1/2
Explanation:
The purple shape is a dilation of the black shape.
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
Now findd the scale factor.
If given two shapes and need to find the scale factor, We must know which one was the original and which one is the image or the new shape. Then we need to know the length of corresponding sides and set them up in a ratio
Answer:Scale factor = 1/2
The purple shape is a dilation of the black shape.
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

Error Analysis A contractor purchases 5 dozen pairs of padded work gloves for $69.60. He
incorrectly calculates the unit price as $13.92 per pair for the expense report What is the correct unit
price? What is the error?
The correct unit price is $ per pair
Answer:
The correct unit price is $1.16 per pair.
The contractor calculated the unit price in terms of per dozen.
Step-by-step explanation:
Given that:
Cost of 5 dozen pairs = $69.60
Unit price per dozen = [tex]\frac{69.60}{5} =\$13.92[/tex]
Unit price means the price of one pair of padded work gloves, so we will convert dozens into unit.
1 dozen = 12 pairs
5 dozen = 60 pairs
Unit price = [tex]\frac{69.60}{60}[/tex]
Unit price = $1.16 per pair
Hence,
The correct unit price is $1.16 per pair.
The contractor calculated the unit price in terms of per dozen.

The coordinates of the vertices of △XYZ are X(−5, 5), Y(−3, −2), and Z(4, 0). The slope of XZ is __, the slope of YZ is __, and the slope of XY is __. △XYZ __ a right triangle because ____________.
-7/2 -5/9 -2/7 2/7 9/5 is is not no two of these slopes have a product of -1 two of these problems have a product of -1
Answer:
Slope of XZ = -5/9
Slope of YZ = 2/7
Slope of XY = -7/2
Step-by-step explanation:
Slope is expressed as;
m = y2-y1/x2-x1
For XZ
X(−5, 5), and Z(4, 0)
Slope of XZ = 0-5/4-(-5)
Slope of XZ = -5/4+5
Slope of XZ = -5/9
For YZ
Y(−3, −2), and Z(4, 0).
Slope of YZ = 0-(-2)/4-(-3)
Slope of YZ = 2/4+3
Slope of YZ = 2/7
For XY
X(−5, 5), Y(−3, −2)
Slope of XY = -2-5/-3-(-5)
Slope of XY = -7/-3+5
Slope of XY = -7/2
For two lines to be perpendicular, the product of their slope must be -1
Taking the product of XY and YZ
mXY * mYZ = -7/2 * 2/7
mXY * mYZ = -1
since the product of mXY and mYZ is -1. this shows that line XY is perpendicular to YZ and showing that the triangle XYZ is right triangle

Answer:
x = 12
Step-by-step explanation:
Reference angle = 45°
Opposite side length = x
Hypotenuse = 12√2
Thus, to find x, apply trigonometric ratio.
[tex] sin(45) = \frac{x}{12\sqrt{2}} [/tex]
Multiply both sides by 12√2
[tex] sin(45)*{12\sqrt{2}} = x [/tex]
[tex] \frac{1}{\sqrt{2}}*{12\sqrt{2}} = x [/tex] (sin 45 = 1/√2)
[tex] \frac{1*12\sqrt{2}}{\sqrt{2}} = x [/tex]
[tex] \frac{12\sqrt{2}}{\sqrt{2}} = x [/tex]
12 = x
x = 12

Answer:
24/9 or $2.67/year
Step-by-step explanation:
Martha is looking into investing a portion of her recent bonus into the stock market. While researching different companies, she discovers the following standard deviations of one year of daily stock closing prices.
Eye Remember Enterprises:
Standard deviation of stock prices
= $1.25 = $1.25
The Azure Travel Company:
Standard deviation of stock prices
= $9.73 = $9.73
Based on the data and assuming these trends continue, which company would give Martha a stable long-term investment?
A. The Azure Travel Company; the larger standard deviation indicates that The Azure Travel Company has less variability in its closing prices than Eye Remember Enterprises.
B. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has less variability in its closing prices than The Azure Travel Company.
C. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has a greater mean closing price than The Azure Travel Company.
D. The Azure Travel Company; the larger standard deviation indicates that The Azure Travel Company has a greater mean closing price than Eye Remember Enterprises.
Answer:
Based on the data and assuming these trends continue, the company that would give Martha a stable long-term investment is:
B. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has less variability in its closing prices than The Azure Travel Company.
Step-by-step explanation:
The result shows that the greater the standard deviation of the stock price of the Azure Travel Company than that of Eye Remember Enterprises, the greater the variance between each stock's price and their mean closing prices. This implies a larger price range in the stock of the Azure Travel Company than it is the case with the Eye Remember Enterprises. It is noteworthy that a volatile stock has a high standard deviation, while the standard deviation of a stable blue chip stock is usually rather low.
