Her sister invited 22 guests. What you have to do to solve this problem is subtract 41-19. We have to do this because Rayliegh invited 19 more people than her sister, but invited a total of 41 people herself. So, to figure out how many people her sister invited we have to know that Rayliegh invited 19 more people and we have to subtract that from the total number she invited to get how many people her sister invited: 22 guests. Can you make me brainliest?
Answer:
1) A. y = x + 2
Once a line of best fit has been placed upon a scatter graph it is straightforward to find the equation. The general equation of a straight line is: y = mx + c Where m is the slope (gradient) of the line and c is the y-intercept.
4) d. strong positive correlation.
The slope of the line is positive. Most points lie close to the line.

Each day it decrease $2. So just multiply $2 x 4 days. It changed a total of $8.
Answer:
r = 54 miles per hour
Step-by-step explanation:
Since we have been given the values for two of the unknowns, we can substitute them into the equation to find the third.
d = 405
t = 7.5
d = rt
405 = r (7.5)
405=7.5r
Now to find r, we need to get it by itself on one side so we have r = ...
We can do this by dividing 7.5 from both sides of the equation as this will cancel out the 7.5, leaving us with the r value, and everything you do to one side of an equation must also be done to the other side.
405/7.5=7.5r/7.5
54=r
The unknown value 'r' = 54
Since 'r' stands for 'rate', the units given must be appropriate for speed. As the distance was given in miles, and the time in hours, the unit for 'r' must be miles/hour. Therefore r=54miles/hour.
