Answer:

Add

3 over 20

+ 7 over 16

= 47 over 80

Step 1 of 2: Add, sub-step a: Find the common denominator.

Find common denominator

3 over 20

+ 7 over 16

= ( 3 × 4 ) over ( 20 × 4 )

3 × 4

20 × 4

+ ( 7 × 5 ) over ( 16 × 5 )

7 × 5

16 × 5

= 12 over 80

+ 35 over 80

80 is the least common multiple of denominators 20 and 16. Use it to convert to equivalent fractions with this common denominator.

Add

12 over 80

+ 35 over 80

= ( 12 + 35 ) over 80

12 + 35

= 47 over 80

(01.05) Use the graph below to answer this question: graph of line going through negative 1, 4 and 2, 0 Find the average rate of

dsp73

1) Find the graph of a line passing through (-1, 4) and (2, 0).

The slope of two points can be determined by dividing the difference of y-values by the difference of x-values:

$\frac{4-0}{-1-2} =\frac{4}{-3}$

The slope of this equation is -4/3. Inputting this into the slope-intercept form of an equation, we get:

$y=\frac{-4}{3} x+b$

To find b, substitute x and y for one of the given coordinate pairs:

0 = (-4/3)(2) + b

0 = -8/3 + b

8/3 = b

Substitute the b value into the equation to finish the line:

$y=\frac{-4}{3} x+\frac{8}{3}$
