Use the points (2, 14) and (10, 22) to write the equation of the line of best fit shown
HELPPP PLEASEEEEE
Answer:
The equation of the line best fit is y = x + 12
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptThe rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ The line passes through points (2, 14) and (10, 22)
∴ x1 = 2 and y1 = 14
∴ x2 = 10 and y2 = 22
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{22-14}{10-2}=\frac{8}{8}=1[/tex]
∴ m = 1
→ Substitute it in the form of the equation above
∴ y = (1)x + b
∴ y = x + b
→ To find b substitute x by 2 and y by 14 in the equation
∵ 14 = 2 + b
→ Subtract 2 from both sides
∴ 14 - 2 = 2 - 2 + b
∴ 12 = b
→ Substitute it in the equation
∴ y = x + 12
∴ The equation of the line best fit is y = x + 12

What is the rate of change in y per unit change in x for the function 30x + 5y = 15?
Answer:
to find the answer you have to put it into y=mx+b format.
This means that it will be 5y=-30x+15
So it will simplify to y=-6x+3
This means that:
If y=2
You substitute then…
2=-6x+3
So x would equal 1/6.
Step-by-step explanation:
The rate of change is -1/6.
What is rate of change?Rate of change (ROC) refers to how quickly something changes over time. It is thus the acceleration or deceleration of changes (i.e., the rate) and not the magnitude of individual changes themselves. In finance, rate of change is used to understand price returns and identify momentum in trends.
The units on a rate of change are “output units per input units.” The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
Given:
30x + 5y = 15
We know that the equation of line y= mx + b
Now, using 30x + 5y = 15
5y=-30x+15
Dividing both side by 5.
y = -30x/5 + 15/5
y = -6x + 3
let us take y= 4
4 = -6x + 3
1 = -6x
x= -1/6

Donna bought 6 CDs that were each the same price. Including sales tax, she paid a total of $84.60 . Of that total $4.20, was tax. What was the price of each CD before tax?
Answer:
$13.40
Step-by-step explanation:
First you subtract the lax from the total cost of the CDs then you divided that total by the number of CDs which is 6.
84.60 - 4.20 = 80.40
[tex]\sqrt[6]{80.40}[/tex] = $13.40
Work out the percentage change to 2 decimal places when a price of £70 is increased to £99.
Answer: Your answer is 41.43%
To calculate, it is simply (99-70)/70 x 100
which is equal to 41.43%
Step-by-step explanation:
The percentage change in the price is 41.42%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a price of £70 is increased to £99.
Now, the difference is 99-70=29
Percentage increase is 29/70 ×100
= 0.4142×100
= 41.42%
Therefore, the percentage change in the price is 41.42%.

Using π = 3.14, find the area of a circle with a radius of 7. Round your answer to the nearest hundredth
Answer:
The formula for calculating the circumference (C) of a circle, C = πD or C = 2πR, is simple if you know the circle's diameter (D) or radius (R). But what do you do if you only know the circle's area? Like many things in math, there are multiple solutions to this problem. The formula C = 2√πA is designed to find a circle's circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.
