Look at the graph: What is the slope?

Answers

Answer 1

Answer:

Answer:

The slope is 2/3

Step-by-step explanation:

The line crosses through the blue grid lines leaving gaps on each. Find two points which cross at an intersection such as (0,30) and (30,50). Find the slope by substituting these points into the slope formula:

$m = (y_2-y_1)/(x_2-x_1) = (50-30)/(30-0) =(20)/(30) =(2)/(3)$

Rob and Lila try to simplify 18 x 4² + (9 - 3)². Rob simplifies the expression and gets 360. Lila simplifies it and gets 324. Which student is correct? What error did the other student make?

Answers

Answer:

Lila is correct and Rob is incorrect because she apply wrong property.

$18 * 4^2+(9-3)^2=324$

Step-by-step explanation:

Given : Rob and Lila try to simplify $18 * 4^2+(9-3)^2$

Rob simplifies the expression and gets 360. Lila simplifies it and gets 324.

To find : which student is correct and what error did the other student.

Solution: First we simplify the expression:

$18 * 4^2+(9-3)^2$

$=18 * 16+(6)^2$

$=288+36$

$=324$

The solution of the expression is 324 which means Lila simplifies correct.

The mistake is found in Rob,

She simplify $(9-3)^2$ like $9^2-3^2=81-9=72$ and she put this in equation

$18 * 4^2+(9-3)^2$

$=18 * 16+9^2-3^2$

$=288+72$

$=360$ which is totally in correct.

because $(a+b)^2=a^2+b^2+2ab$ she use wrong property.

Lila is correct. Rob is wrong because he multiplied 18*4^2 and he gets 288 and then he added 81 and subtracted 9 and that gave him 360.

1. Describe a situation that models a linear pattern and then describe a situation that models a nonlinear pattern. Do not state which situation is linear and which is nonlinear.

Your classmates will need to determine which is which and then write a function that models the linear situation.

Your classmates will also need to write 1 ordered pair that is a solution to the linear function and explain its meaning in the context of the situation.

Answers

While it says not to state it, I will state which one is which, just for clarification.

Linear Pattern: A person is paid $10 for every hour they work. Before they start working, they are given an additional $5. They receive no raises in their pay.
This is linear because the pay is constant, and they aren't receiving any additional money. The equation for this would be y = 10x+5, x is the amount of hours they work.

Non-Linear Pattern: A person is paid $10 for every hour they work. Before they start working, they get are given an additional $5. For every 30 minutes they work after hour 4, they receive a $1 raise.
This is non-linear because the pay, after a certain amount of time, would go up, and the graph would soon start going higher after hour 4.

An ordered pair for the linear would be: (5, 55)
After working 5 hours, they would have $55.

An ordered pair for the non-linear would be (5, 56)
After working for 5 hours, they would have $56.

The ratio of white to green marbles in a bag is 5/12. How many green are there if there are 51 total marbles? Please explain how to do ratios and porprotions. (:

Answers

So for every 5 white marbles there are 12 green ones.
The easiest way to do this is to increase the ratio.

so: 5white/12green=17total
10w/24g=34 total
15w/36g= 51 total
