Step-by-step explanation:

when the y = 69 the x = 420

Answer:

The answer is y = 1/8x

Step-by-step explanation:

Slope-intercept form is y = mx + b, with m being the slope and b being the y-intercept.

In this graph, we can see the line intersects the y-axis at point (0, 0). This means the y-intercept is 0, so we don't have to add it in the equation.

To find the slope, we use the formula m = (y₂ - y₁)/(x₂ - x₁) using two coordinate points on the line: (0, 0) and (8, 1).

Substituting it in the formula, we get m = (1 - 0)/(8 - 0), which simplifies to 1/8.

Putting this information into slope-intercept form, we get that the equation of the line in slope-intercept form is y = 1/8x.

Please tell me how you got it very clearly



Any spam, nonsense, links, and anything that does not relate to this question will get deleted. Thank you.

Answers

So first you gotta convert 2 2/5 into and improper fraction which gives you 12/5. Which brings you to 12/5 x 5/7, you’re gonna wanna cross cancel the most common factor which is the number 5 and that leaves you to build up the fraction 12/7. Now you wanna convert your improper fraction to a mixed number, and you do that by putting it in long division form otherwise said as 12 divided by 7 which leaves you with 1 and a remainder of 5. 1 5/7 is your answer
If your problem is a fraction I can help… 1 5/7

Answers

Answer:

He has 286 dollars in his bank account at the end of the month.

Step-by-step explanation:

Deposit Meaning- basically to add

Withdrawal- basically to subtract

154+237+45= 436

-125-25= -150

436-150= 286

I think the last answer is wrong. No offense. If he starts with $154 and I deposited 237 bring it Up to 391 then he withdraws $25 so you subtract that and you get 366 then he withdraws another 125 bringing it down to 241 then he deposits $45 bringing him up to 286. 286 is your answer and make sure you put dollars as the unit. Hope this helps!

Zachary purchased a computer for $1,600 on a payment plan. Two months after he purchased the computer, his balance was $1,370. Four months after he purchased the computer, his balance was $1,140. What is an equation that models the balance y after x months?

Answers

Answer:

Step-by-step explanation:

You are finding out each time how much is the items Zachary bought.

Then inputting a equation

$1,600 - ??? = $1,370

To find the unknown number, you must subtract the 2 original numbers.

$1,600 - $1,370 = $230

Computer costs: $230 leaving Zachary with $1,370 left.

Next, it says he purchased another computer...

$1,370 - ??? = $1,140

Again, we subtract the 2 original numbers to find the unknown.

$1,370 - $1,140 = $230 leaving Zachary with  $1,140 left.

Now we input this data into an equation...

y = -230x + 1600.
