3) Since there are 12 months in a year, there are four groups of 3 months in a year.

So, if 420 dollars are saved every three months, a total of

420\cdot 4 = 840

dollars will be saved per year.

4) Using the given figure, the difference between the two numbers is composed by two little squares. If this difference is 72, then one little square is 36.

The sum of the two numbers is composed by 8 little squares, for a total of

36\cdot 8=288

The line passes through the points ( 7, -7) and ( 6, -5) a. y = -2x + 7 c. y = -2x - 7 b. y = 2x - 21 d. y = 2x - 7
ollegr [7]
Slope = (-5+7)/(6 - 7) = -2

y = mx + b
b = y - mx
b = -7 - (-2)(7)
b = -7 + 14
b = 7

equation
y = -2x + 7

A jogger goes half a mile north and then turns west. If the jogger finishes 1.3 miles away from the starting point, how far west
Ratling [72]
In order to solve this problem, you must draw a right triangle first to help you visualize the path of the jogger. 
You are given 0.5 miles north (which will be the height of the right triangle), and 1.3 miles (which will be the hypotenuse of the triangle). 
Using Pythagorean Theorem: a²+b²=c², we have:
0.5² + b² = 1.3²
b = 1.3²-0.5²
b = 1.2 miles
