It’s going up 6 and right 4
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.
Let's write an equation describing the problem.
Any even whole number may be represented by writing

in which

is any non-negative integer.
It follows that for a even whole number

the next (consecutive) even whole number can be written as

.
We now need to solve the following equation:

If we solve for

we get:

We have to values, as the equation is quadratic. We take the positive one as the correct one. So

, and if we plug in this value to

and

we know that the
asnwer is 16 and 18.
Answer:
28 pans of muffins per week
Step-by-step explanation:
To solve the above question, we know that:
1 day = 4 pans of muffins
7 days = x pans of muffins
Cross Multiply
1 day × x pans of muffins = 7 days × 4 pans of muffins
x = 28 pans of muffins
Since, 7 days = 1 week
Heather makes 28 pans of muffins per week
