Answer:
35v - 56w + 14
Step-by-step explanation:
Step 1: Equation
7 ( 5v - 8w + 2 )
Step 2: Multiply out the equation
( 7 × 5v ) - (7 × 8w) + ( 7 × 2 )
Step 3: Simplify
35v - 56w + 14
Answer:
35v - 56w + 14
Hope This Helps :)
Part A
The scatterplot is shown the attachment.
Part B
Using a linear regression equation that models Patrick's referrals has a positive slope.
This means that, there is a positive relation between time(number of days),x and the number of personal recommendations, y.
In other words, as the number of days increases, the number of personal recommendations also increases.
Question 2.
The given functions are:
To find the point where the graphs of these functions intersect,we solve the two equations simultaneously.
We equate the two equations to get:
Factor to obtain:
x=3 and x=-2
We put x=-2, into to get;
when x=3 
Therefore the graphs intersect at (-2,-7) and(3,13).
Yes, solution is correct.
If there are 20 children that went to eat lunch, and 14 of them ate fish burgers, and 10 ate chicken burgers, you could make a line graph with 20 points and color the kids who ate fish burgers yellow and the one who ate chicken burgers blue. The green where they overlapped, and 10 of them over lapped, meaning that <u>10 children ate both fish and chicken burgers. </u>Hope I helped!
Answer:
In order from left to right: 3.5, 3, 60, 70
Parallel have same slope
Perpendicular have opposite reciprocal slopes. Ex. 2/3 is slope of one line so the perpendicular line would have slope of -3/2.
Find slopes of these lines.
-4x-5y=-4
-4x+4 =5y
Divide by 5
Y= -4x/5 +4/5
Second line: 10x-8y=-1
10x+1=8y
Divide by 8
10x/8 +1/8 =y
Y= 5x/4 +1/8
So if you look at slope of line 1= -4/5 and line 2 it’s 5/4 so these both are perpendicular.
