Answer:

m=\frac{1}{ab}

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(a,1/b) and (b,1/a)

substitute

m=\frac{1/a-1/b}{b-a}

m=\frac{\frac{b-a}{ab}}{b-a}

m=\frac{1}{ab}

Write a numerical expression for each verbal phrase.
Nookie1986 [14]

Answer:

Option B. 16-8

Step-by-step explanation:

Let

z ------> the number of apple left

x -----> the total number of apples

y -----> the number of apples sold

we know that

The numerical expression of the phrase " the number of apples left if eight out of the sixteen apples have been sold" is equal to subtract the number of apples sold from the total number of apples

so

z=x-y

we have

x=16 apples

y=8 apples

substitute

z=16-8

5x = 3x + 24

2x = 24
