How do u find a equation passing through the line in a graph, I will give an example (-2,0) and (0, 5), I don’t understand how to calculate it can u please give me a easy way to do it for me , I’m in the 8th grade

Answers

Answer 1

Answer:

y = 5/2x + 5

Step-by-step explanation:

To find the equation, you first need to find the slope. You can do this by subtracting the two y coordinates (the two last numbers) and using that as the numerator (the top number of the fraction), and then subtracting the two x coordinates (the two first numbers) and using that as the denominator (the bottom number of the fraction). You then have the fraction -5/-2, which can be changed to 5/2 because they are both negative numbers. That is your slope. You then need to find the y-intercept (where the line connects with the y-axis). To do this, you need to figure out what the y (the second number) is when the x (the first number) is 0. In this example, you can already see with the second set of coordinates that the y-intercept is 5 because the x is 0. When this is not easily shown, you can figure out the y-intercept with a table. Sorry if I made it sound too complicated :)

For number 1, the answer should be -g(x) = -x - 4

Number 2 should be h(x) = -0.5x + 3

5 Michael has $16.25 in the bank. He needs $108 to buy a video game. He finds he can
save $1.75 a week from his allowance. How many weeks must he save in order to have
enough to buy the game?

Answers

Answer:

53 weeks (rounded)

Step-by-step explanation:

First, subtract 16.25 from 108 (108 - 16.25), resulting in 91.75

Next, you divide. 91.75/1.75

You would get 52.42... but you would have to add a week to actually get the game.

53 weeks I think but I rounded it

Answers

Answer:

x < - 5

Step-by-step explanation:

Given equation:

5 + x = n

If n is negative then we get:

n < 0 or5 + x < 0x < - 5

If n is negative then x is less than - 5.

Example:

x = - 6 ⇒ 5 + (-6) = 5 - 6 = - 1 ⇒ -1 < 0

Answer:

x < -5

Step-by-step explanation:

Now the value of x is,

→ 5 + x = n

→ x = n - 5

The value of n when negative,

→ n < 0 ---- {n = 0}

When n is a negative number,

→ x < 0 - 5

→ [ x < -5 ]

Hence, the answer is x < -5.

Angie bikes for 20 minutes burning 150 calories. How many minutes will it take to burn 525 calories?

Answers

Answer:

70 minutes OR 1 hour and 10 minutes (it's the same thing)

Step-by-step explanation:

So this can be modeled by the equation 20/150=x/525

so solving for x, you have to say whats the most times that 150 will go into 525 without going over

the answer is 3

so 150x3=450 and 525-450=75

75 is one half of 150 so it would be 3.5

multiply 20 by 3.5 and you get 70 or 1 hour and 10 minutes since an hour is 60 minutes

Don't forget to give brainliest :)

1. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

2. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. A proportion is an equation that states that two ratios or rates are equivalent.

3. As defined in the lesson on Unit Rate and Proportionality, the unit rate is the rate of change in a relationship where the rate is per 1.

4. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)

Data set 1: Has a mean of 84 and a MAD of 6. Data set 2 Has a mean of 78 and a MAD of 8 I need to find out what the means to Mean Absolute Deviation (MAD) ratio is.

My teacher keeps telling me that it is 0.75, but I can't seem to get the right formula to it to answer right. can anyone help?

Answers

Answer:

0.75 or 6/8

Step-by-step explanation:

This is probably a late answer but I thought I would go ahead and respond.

When you have two data sets with the same variance, the ratio of the means to MAD is a way to test for the pooled variance of the two data sets

Given Data Set 1 with mean M1 and mean absolute deviation with MAD1 and another data set 2 with mean M2 and MAD2 the means to MAD ratio is given by the ratio of the absolute difference in means to the largest of the MADs

Here M1 = 84 and M2 = 78 so the absolute difference is |84-78| = 6

The larger MAD is MAD2 = 8

So the ratio is 6/8 = 3/4 = 0.75
