Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Time, in years. The vertical axis is labeled Number infected. Points are plotted at (one, one hundred), (two, ninety), (three, seventy-five), (four, sixty), (five, forty-five), (six, twenty-five), (seven, fifteen), (eight, five), (nine, zero).

If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.
Slope is = (60-70)/(25-20) = -2
Using the two-point slope form, y – y1 = m(x – x1)
y – 70 = -2(x – 20)
y – 70 = -2x + 40
y = -2x + 110
Step-by-step explanation:
The associate that best describes the scatter plot is the Negative association.
What is an associate?An associate in a scatter plot tells us the relation between the two variables. There are 4 types of associates:
Positive associate: If the value of one variable is increasing the value of another increase as well, but the relation is not linear.
Negative associate: If the value of one variable is decreasing with the value of another increasing as well, but the relation is not linear.
Linear Associate: If the value of one is dependent on the other such that they follow a function of line, and all the data points are on that function line or near to it.
Non-linear Associate: If the data points of the plot are scattered and random, such that there is no relationship between the points.
If we plot the graph of the data points we will see that the trend of the data is negative, therefore, the value of one variable is decreasing with an increase in the value of another.
Hence, the associate that best describes the scatter plot is the Negative association.

Answers
Answer:
Step-by-step explanation:
The equation is mx+b=y.
M=slope (in this case 5)
x=x coordinates
b=y intercept
y=y coordinates
For the x and y coordinates, I'll use (2,0).
5(2)+_=0
10+_=0.
In this case, we only have one awnser, -10. Since 10+(-10) are the only ways to equal 0.

Answer: [tex]12*\sqrt{2}[/tex]
Step-by-step explanation:
We have the equation:
[tex]\frac{14}{\sqrt{2} } + \sqrt{50}[/tex]
we know that:
14*14 = 196
then:
14 = √196
[tex]\frac{\sqrt{196} }{\sqrt{2} } + \sqrt{50} = \sqrt{196/2} + \sqrt{50} = \sqrt{98} + \sqrt{50}[/tex]
Now, we can rewrite:
50 = 2*25
98 = 2*49
This is because we know that 49 and 25 are perfect squares, then:
[tex]\sqrt{98} + \sqrt{50} = \sqrt{2*49} +\sqrt{2*25} = \sqrt{2} *\sqrt{49} + \sqrt{2} *\sqrt{25}[/tex]
Now we can use the common factor √2 and get:
[tex]\sqrt{2} *\sqrt{49} + \sqrt{2} *\sqrt{25} = \sqrt{2}*(\sqrt{49} + \sqrt{25} )[/tex]
and we know that:
7*7 = 49
5*5 = 25
then:
[tex]\sqrt{2}*(\sqrt{49} + \sqrt{25} ) = \sqrt{2}*(7 + 5) = 12*\sqrt{2}[/tex]

Stephanie took advantage of the interest-only financing from Rooms-To-Go and borrowed $2,000 with a 15 percent annual interest rate. How much will she have paid in interest after 8 months?
Answers
Answer: $200
Step-by-step explanation
Principal = $2000
Rate = 15%
Time = 8 months = 8/12 = 2/3 years
Interest = Principal × Rate × Time
= 2000 × 15% × 2/3
= 2000 × 15/100 × 2/3
= $200
The interest is $200

Today, everything at a store is on sale. The store offers a 20% discount.
1. The regular price of a T-shirt is $24. What is the discount price?
2. If the regular price of an item is x dollars, what is the discount price in dollars?
3. The discount price of a hat is $14. What is the regular price?
Answers
Answer:
a) $19.2
b) 0.8x
c) $17.5
Step-by-step explanation:
1. We want to find the discount price given the regular price
The discount is 20%
so the discount price will be;
24 - 20% of 24
24 - 4.8 = $19.2
b) We have this as;
x - (20% of x)
x - 0.2x = 0.8x
c) let the original price be x
x - 20% of x = 14
x - 0.2x = 14
0.8x = 14
x = 14/0.8
x = $17.5

Step-by-step explanation:
Notice that the x-coordinate remains the same, 7, for both points, whereas the y-coordinate changes. Thus, the line through these two points is a vertical one: x = 7. No, this is not a function, since one x value (7) has more than one y values associated with it.

Answers
Answer:
29 degrees
Step-by-step explanation:
Given
<D = 2x+8
<A = 122
The sum of the adjacent angle of the trapezoid is 180 degrees
<D + <A = 180
2x + 122 = 180
2x = 180-122
2x = 58
x = 58/2
x = 29 degrees
Hence the value of x is 29 degrees

Answer:
y = [tex]\frac{3}{4}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 5) ← 2 points on the line
m = [tex]\frac{5-2}{4-0}[/tex] = [tex]\frac{3}{4}[/tex]
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = [tex]\frac{3}{4}[/tex] x + 2 ← equation of line

We need to find the percentage decrease in the value of temperatures.
The percentage decrease in any value is given by :
[tex]\%=\dfrac{|\text{initial value-final value}|}{\text{initial value}}\times 100\\\\=\dfrac{21-17}{21}\times 100\\\\=19.04\%[/tex]
