Ok question is there numbers with this
Answer:
X=3
Step-by-step explanation:
For a linear equation like 2x + 3 = 9 you would start with subtracting 3 from both sides. Then you would divide both sides by 2 to get x by itself. You get x=3
For linear inequalities it’s the same but with a less than or equal sign. You just solve the same way. However if you divide a negative the sign flips like in my second example. I’m not sure if this is exactly what you are looking for since I don’t know what your problems look like but I hope it helps.
The function shows that the cost of hotdogs is 1.75 and the cost of hamburger is 1.5.
<h3>How to calculate the information?</h3>
Let hotdogs = h
Let hamburger = x
The expression will be:
h + x = 3.25
h + 7x = 12.25
Subtract the functions
6x = 9
x = 1.5
Therefore, hot dogs will be:
= 3.25 - 1.5
= 1.75

Answer:

Step-by-step explanation:
First you have to find the slope
Now use the point-slope form by using one of the points and the slope. Let's use the point (3, 3)

Multiply thru the equation by 3 to remove the fraction
3y - 9 = -2(x - 3) =
3y - 9 = -2x +6
3y = -2x + 15
is the equation in slope-intercept form
