Answer:y = 2x − -3 find the y and x and then identify if its zero slope or undefined.
Step-by-step explanation:
Hi there! The answer is A.

To get a proper idea of the type of function this formula represents we work out the parenthesis.
Working out the parenthesis can for instance be done using rainbow technique.

We can now see sinilarities between this function an the general function of a line in slope intercept form

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
These equations do match up. All you have to do is find the solution to the first equation. After that, plug in that solution to the second equation. If it makes the equation true, then the equations match.
Hope this helps!
Answer:
x=10.5
Step-by-step explanation:
if the two triangles were ratios it would be like
19.3:7.2 to x:3.9
so 75.27 = 7.2x
whcih is 10.45 which is approximately 10.5
