Y=3(x-2)+1 how can i graph this into slope intercept form

liraira [26]

Answer: y=3x--5

Step-by-step explanation: First simplify by distribution and lie terms to get:

y=3x-5

3 is your slope which means every time your y goes up three your x goes across one.

-5 is your y-intercept which means (0,-5) goes through your line

Show that the equation x^3+6x-5=0 has a solution between x=0 and x=1

Mnenie [13.5K]

Answer:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

Step-by-step explanation:

The equation f(x) given is:

$f(x) = x^3+6x-5$

For x = 0. the value of the expression is:

$f(0) = 0^3+0-5\\f(0) = -5$

For x = 1, the value of the expression is:

$f(1) = 1^3+6-5\\f(1)=2$

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

In other words, there is at least one solution for the equation between x=0 and x=1.

Write an equation to represent the total amount Shauna will owe her parents

Misha Larkins [42]

This would actually be a very broad question. So, when considering these kinds of questions, one thing that we would really want to consider would be the $(x)$ value in this case. We would want to find the amount, and also the terms of the expression.

So, let's suppose that the amount would be 200.

And let's say that Shauna makes 5 a week.

Then the expression would then look like $\boxed{5w=200}$

$(w)=weeks \\ \\ (5)= how \ much \ she \ makes \ in \ a \ week. \\ \\ so \ we \ do \ the \ amount \ she \ makes, \ and \ then \ \\multiplied \ by \ the \ amount \ of 
 \ weeks.$

I hope this would help you in your case of the problem! :)
