Answer:

a third 1/3

Step-by-step explanation

first write the equation

express 8 to power form = 2^3x don't forget the unknown , which is x

it becomes ; 2^3x = 2^1

since the base numbers are same, cancel them.

equate the powers ; 3x=1

divide both sides by the number next to the unknown to get the answer.

One equation in a system of linear equations is y=2x+1

Rufina [12.5K]

Step-by-step explanation:

Given equation:

y = 2x + 1

a. write a second equation so that (1,3) is the only solution of the system

To have only one solution the equation must have a different slope.

Let it be 10, then the y-intercept of y = 10x + b is:

3 = 1*10 + b ⇒ b = -7

And the equation:

y = 10x - 7

b. Write a second equation so that the system has infinitely many solutions

To have infinitely many solutions, both equations must be same:

y = 2x + 1

c. Write a second equation so that the system has no solutions.

To have no solutions, the equations must have same slope but different y-intercepts:

y = 2x + 5

Please help (will mark brainliest)

Alexxandr [17]

Let's look at number 5 first. We can put this into slope-intercept form. Slope intercept form is stated as $y = mx+b$ , where $m$ is the slope and $b$ is the y-intercept. The slope here is $\frac{2}{3}$ . The y-intercept is 30. Therefore, the answer is $y=\frac{2}{3} x + 30$ .

Using the same logic, we can solve number 6 and get the answer of $y=3x+120$ .
