Answer:
The line of best fit is used to express a relationship in a scatter plot of different data points.
Step-by-step explanation:
Your answer is 18 because of this very important rule five or above give it a shove four or less give it a rest so since six is higher then you give it a shove and u get 18
Answer:
Equation of a line is y = mx + c
where m is the slope
c is the y intercept
From the graph using points ( 5 , - 4) and
( -5 , 2)
Slope = 2+4/ -5 - 5= 6/-10 = - 3/5
Equation of the line using point (5,-4) is
y + 4 = -3/5(x - 5)
y = -3/5x + 3 - 4
y = -3/5x - 1
Hope this helps

Step-by-step explanation:
<u>Step 1: Define</u>
6 - 9x = 5x - 9x + 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 6 - 9x = -4x + 16
- Add 9x on both sides: 6 = 5x + 16
- Subtract 16 on both sides: -10 = 5x
- Divide 5 on both sides: -2 = x
- Rewrite: x = -2
Answer:
ratio is 9;4
Step-by-step explanation:
let ratio be 3x ans 2x
by question
2πR/2πr=3x/2x
R/r=3/2
area
πR²/πr²=(3/2)²=9/4
