Subtract 7 from -2 and 7 since 7 is currently a positive number
Your equation should now look like this:
-3x=-9
Next you have to divide by 3 on each side to get:
X=3
Answer:
(y-p)/2
Step-by-step explanation:
take p to the left side. + p becomes - p. Now divide the whole thing by 2
is the answer.
This is because the slop is found by the difference of ys over the difference of xs.
Hello!
In a function, each input has only one output. In A, three has two outputs, 4 and 5, so A is not a function.
In B, you can use something called the vertical line test to see if each x value has one y value as an output. You move an imaginary vertical line across the graph, and if it intersects with two points it is not a function. If we do this on our graph, it will not intersect two points. Therefore, B is a function.
In C, we can see that each input has one output, or there are all different inputs, so C is a function.
For D we can use that vertical line test again. It intersects both the points (-1,1) and (-1,6) so D is not a function
Our final answers are B and C.
I hope this helps!
Step-by-step explanation:
If were estimating, 39 is pretty close to 40 and 40x6 is 240 pounds. if we are getting exact about it, then 234 pounds
