Of the following options what could be a possible first step in solving the equation -7x-5=x+3

1 answer:

4 0

Sorry for not answering till now! But since the first one you meant 7x it makes sense now!

You just have to look at each answer and see what it does for you. Subtracting 5 from both sides doesn't help you. Adding x to both sides doesn't help you. And there are no like terms to combine in the condition the equation is in.

Now if you add 7x to both sides though, it helps you. :)

Hope that helps! Feel free to ask me if you have any questions! :3

Answer:

function b

Step-by-step explanation:

When its asking for which function has a greater rate of change its asking for which slope has a greater value

the slope is calculated by change in y over change in x

for function a, as y goes up 2 x goes up 1

so the slope ( rate of change) is 2/1

for function b is y goes up 3 x goes up 1

so the slope (rate of change) is 3/1

3/1 is greater than 2/1 so function b has a greater rate of change

3.3.1. Calculate the new cost per night of the standard and family standard chalets. Round of (4) your answer to the nearest hun

Taya2010 [7]

The information to complete the table is given below:

Equation that shows the relationship between the cost per night C and the number of people staying in the chalet n: C= 4000-100(n-1)

<h3>What is Equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in math when you do not know the exact number in a calculation.

Given that:

Pules Rs 4000 per night but will decrease the amount by R100 per person occupying the chalet.

Number of People Cost per night

1 4000

2 3900

3 3800

4 3700

5 3600

6 3500

7 3400

8 3300

9 3200

10 3100

let C be cost per night and n be the number of people of staying in chalet.

equation: C= 4000-100(n-1)

for n=1: C= 4000- 0=4000

n=2, C= 4000-100(1)= 3900

The graph is attached below:
