Given:
Scatter plot of weight loss plan.
To find:
how many pounds were lost per month with 4 hours of weekly.
Solution:
Take any two points on the trend line.
Let the points are (3, 4) and (5, 7).
Slope of the line:
m = 1.5
Using point-slope formula:
Add 4 on both sides.
Approximate equation of a line is y = 1.5x - 0.5
Substitute x = 4.
y = 1.5(4) - 0.5
y = 6 - 0.5
y = 5.5
Which is nearly equal to 6.
Also see in the scatter plot, y-value for the corresponding value of 4 in x-axis is 6.
Hence 6 pounds lost per month with 4 hours of weekly aerobic activity.
Answer: 12.2
Step-by-step explanation: Pythagorean Theorem
Answer:
-217 is the answer.
Step-by-step explanation:
negative nineteen is -19
eleven = 11
and from their product we have to subtract 8.
so,
-19×11
= -209
-209-8
= -217.

Answer:
x=8, y=-10
Step-by-step explanation:
Using elimination to solve a system of equations works by manipulating one of the equations so you can cancel out a variable to solve the other.
Here, we can change -3x-2y=-4 into -15x-10y=-20 by multiplying by 5. Because of this, we can eliminate the y variable and end up with -5x=-40 which gets you x=8.
Now, we plug x=8 into one of the original equations and solve for y:
10x+10y=-20
10(8)+10y=-20
80 + 10y = -20
10y = -100
y = -10
