Solve the system of equations by substitution.

-8x+2y=4
y=4x+2

Answers

Answer:

the answer by substitution would be y = 4x+2

Correct answer: Infinite solution because 2 = 2.

Set the first equation equal to y.

-8x + 2y = 4

+8x          +8x

___________

2y = 8x + 4

__   ___  __

2      2     2

y = 4x + 2

At this step, you can choose any equation to substitute into the other equation. However, I'm going to substitute the new first equation with the second equation where y is. Solve for x.

y = 4x + 2

4x + 2 = 4x + 2

-4x        -4x

____________

2 = 2

So, at this point, we know the system of equation does not have one solution. Thus, when the same number equals the same number, it is an infinite solution.

We can prove this by an online graphing tool. Insert the two equations onto the online graphing tool. If the lines appear to be on the same line, they have infinite solutions. Hope this helps :) Let me know if you have any questions related to this problem!

Step-by-step explanation:

Sorry for the wait I just saw this question. Lol, I guess answer 1 is always equal to answer two but here is my work:

6(3)+21(4)=18+84=102

2(2(3)+7(4)=2(6+28)=12+56=102

5(6)x7(6)=30+42+72

6(5+7)=6(12)=72

14(10)+2=140+2=142

2(7(10)+1)=2(70+1)=2(71)=142

102+102+72+72+142+142=632

632 squared means 632x2 which is 1264.

In the course of a short race, a car does 50,000 J of work in 7 s. What is the power of the car during the race? (round to the nearest whole number)

Answers

Answer:

Work done is the product of distance and force, it is measured in joules.

Power is the rate of work done given by dividing the work done by time

Power (watts)= workdone (J)/ time (s)

                     = 50,000J/7 sec

                     = 7142.857 watts

Therefore, the power of the car during the race was 7142.857 watts

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.
The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.
The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.
Answer the questions to estimate the probability that the Iceblades will win the game.

Which equation is the BEST fit for the data in the graph

Answers

C. Since the data is going down by -8, and it starts at +45

Answer:

y = -8x + 75 (C)

Step-by-step explanation:

To find this, you first should take a look at the y-intercept (The point at which x=0) to narrow it down a bit. In this case, the y-intercept is 75. The standard form of a linear equation is y = mx + b, where b is the y-intercept. Since there is only 1 answer where b is equal to 75, C is the right answer.
