B is the answer, if you need the reasoning let me know :)
explanation:
we know that linear equations always have a curve that is a straight line (constant gradient) so if we draw each graph out, we can determine which is the linear graph, based on which has a straight line curve. i drew all 4 graphs out, and B was the only straight lined graph, hence this must be the answer. i have attached photos of my graphs above :)
Pls help I’m begging anyone.
They graph it in a werid way so I’m hoping u could take a screenshot and then graph it.
Answers
Answer:
Look at solution
Step-by-step explanation:
Remember that the x-axis is the time so you start at 0. The y-axis is the amount of snow so it says it starts at 1 inch so you start at (0,1).
When using coordinates remember (x,y) the x is the horizontal axis and y is vertical.
The next few steps deal with slope. The slope is always rise/run. so when it says it snowed for an average of 1 inch per hour, you go one up and one to the right to create the line. When it stopped snowing, the snow (i assume) stays the same so you just have a horizontal line for 5 hours indicating the same amount of snow. Then the snow becomes 3 per hour so you have to go up 3 from where you left off and over 1. Do that for 7 hours.
I hope you read this explanation because this is the basics of graphing. Next time you can try it by yourself :)

Customers at a candy store took a survey. The results showed that 126 customers preferred chocolate candy. This represented 35% of the total number of customers who took the survey. How many customers took the survey?
Answers
Answer:
360
Step-by-step explanation:
1. Set up your equation!
[tex]\frac{35}{100}[/tex] = [tex]\frac{126}{x}[/tex]
2. Cross multiply to solve!
100 times 126 = 12600
35 times x = 36x
3. Continue!
12600=35x
4. Divide the coefficient on both sides to get the variable by itself
[tex]\frac{12600}{35}[/tex]=x (the 35 cancels out)
12600 divided by 35 = 360
And there’s your answer! 360

Which table represents the following equation? y=−9x+2 PLEASE HELP!!!!! I NEED TO BE DONE BEFORE 12
Answers
Table (C) represent the equation y = -9x + 2.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
y = -9x + 2.
To find the table that represents the given equation.
Substitute x = 0 in the equation, as in all the options the value of x is 0, so satisfy the value of y for the value of x = 0.
y = -9 (0) + 2
y = 0 + 2
y = 2
The value of y is 2, when x = 0.
The table in option (c) satisfies the condition.
Therefore, option (c) is correct option.
