Answer:

Option A is correct

Step-by-step explanation:

Given two equations

x-y=2....(1)

2x+3y =14...(2)

we have to solve the above equations using elimination method.

Multiplying (1) equation by 2, we get

2x-2y=4....(3)

Subtract equation (3) from (2), we get

3y-(-2y)=14-4

5y=10

Dividing by 5, we get

y=\frac{10}{5}=2

(1) implies x-y=2

x-2=2

x=2+2=4

hence, the solution is (4,2)

Option A is correct.

a science quiz has eight multiple choice questions with five choices for each. Find the total number of ways to answer the quest
almond37 [142]

Answer:

390625

Step-by-step explanation:

The questions are all independent -- the answer on one question does not limit the number of possible answers on another question.

The quiz has 5 choices for each question, so there are

5\times5\times5\times5\times5\times5\times5\times5 ways to answer the quiz questions.

Notice that this could be written 5^8.  You could say that the number of ways to answer the questions is

number \, of \, choices^{number \, of \, questions}

Use a calculator to find 5^8
