Easiest way is if you have a graphing calculator, but if not. Simply plug in values for x, starting at -2 for this equation, and then find the corresponding y values. Then plot.

-8(r-2)=40 what is the answer to this equation
Elena-2011 [213]
The answer is r=-3. You use the distributive property which is basically multiplying -8 with all the numbers inside the parenthesis. So -8 x r and -8 x -2. This results to -8r+16=40 (Two negative numbers multiplied together will form a positive number). We use inverse operations to subtract 16 from both sides. 16-16 is 0 and 40-16 is 24. So we are left with -8r=24. We want to be left with only r, so we once again use inverse operations to divide -8 from both sides. -8/-8 is 1, and 24/-8 is -3. So we end up with r=-3. Hope this helped :]

There are four slices of pepperoni pizza and three slices of veggie pizza sitting on the counter. what is the probability of ran
Otrada [13]

Answer:

The probability of randomly choosing a slice of veggie pizza is 3/7

Step-by-step explanation:

Probability is the measure of uncertainty of any event. It is the ratio of number of favorable outcomes to the total number of possible outcomes. That is,

Probability, P(A) = (Number of a Favourable outcome) / (Total number of possible outcomes).

From the question,

There are four slices of pepperoni pizza and three slices of veggie pizza, this means

Total number of favourable outcomes = 4 + 3 = 7

The favourable outcome is the veggie pizza, therefore

Number of favourable outcome = 3

Hence,

Probability P (A) = 3 ÷ 7

P(A) = 3/7

The probability of randomly choosing a slice of veggie pizza is 3/7
