explain why multiplying the numerator and denominator of a fraction by the same number results in an equivalent fraction

Think:  You're treating the numerator and the denom. in precisely the same way.  In doing so you are NOT changing the value of the fraction, only the appearance.

Example:  start with 2/3.  Mult num. and den. both by 7:  14/21.

2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.

Given m = 2 and the point (-1, 7), which of the following is the point-slope form of the equation?

y-y_1=m(x-x_1)

We have the point (-1, 7) and the slope m = 2. Substitute:

y-7=2(x-(-1))\\\\\boxed{y-7=2(x+1)}\to\boxed{b.}

Answer:

Step-by-step explanation:

3 pounds of apples for x dollars is 3x                 apples

2 bags of spinach for y dollars is 2y                    spinach

5 pounds of apples for x dollars is 5x                 apples

3 bags of spinach for y dollars is 3y                    spinach

Add all like terms.  3x+5x=8x   and      2y+3y=5y  Then we have to add them together by putting them into an equation....8x+5y
