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!

I got 240 so I just need to double-check that. I also need to explain why it's 240 mins? Maybe an expression? Help

Answers

Let’s find the slope of this equation

Slope formula:

(y2-y1/x2-x1)

Plug things in

(-3000-0/20-0)

(-3000/20)

Condense the fraction

Slope = -150 or lowering 150 feet per minute.

Let’s get point slope form, add in some points.

Point slope form:

y - y1 = -150(x - x1)

Plug things in

y - (-3000) = -150(x - 20)

y + 3000 = -150x + 3000

Subtract 3009

y = -150x

Plug in -36000 for y

(-36000) = -150x

Divide by -150

x = 240

You are correct, it took 240 minutes.

Answer:

Look at the image.

Step-by-step explanation:

x - 6 + x = 14

2x - 6 = 14

2x - 6 + 6 = 14 + 6

2x = 20

2x ÷ 2 = 20 ÷ 2

x = 10

We could solve problems like these by plugging in values

Let’s start with A

y = 94x

Let’s use 5, 15, 25 from the table

94(5) = 470
94(15) = 1410
94(25) = 2350

Next, B

y = 5x

5(5) = 25

This is wrong

Next, C

y = x + 470

Let’s try 5

475 = 5 + 470

Close, but wrong

Next, D

10 = 5 + 5

This is wrong, so the answer is A.
the answer is y=94x. pls give brainliest

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.


1. The paired digits 00 to 99 represent 100 shots.
Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.


2. Each group represents the 5 shots taken by the other team. To win the game, the Iceblades cannot let the other team score any goals.
For a group to be a success, how many of the 5 shots does the goalie need to save?


3. Group 1 is a success. Explain why.


4. In this simulation, which groups are successes? How many successes are there in the 10 groups?
