If (a,3) is a point on the graph of y=2x-5, what is a?

1 answer:

3 0

To solve this, you already have the y value of the coordinate, which is 3, and the x value is represented by a. Plug the values into your graph equation so that it looks like this: 3=2a-5
Then, add 5 to both sides to isolate 2a:
8=2a
Finally, divide both sides by 2 to get that a=4
Hope this helps!

15 more than 3 times a number is at most 7

hammer [34]

Answer:

Let x = the number

"Fifteen more than" means addition

"Three times a number" is multiplication

"three less than" is subtraction, as is the term difference

Putting it all together, we have

7 - (15 + 3x) = (9 - 5x) - 3

-8 + 3x = 6 - 5x

-8 = 6 - 8x

-14 = -8x

14/8 = 7/4 = x

Step-by-step explanation:

Photo question; find the length

$\bf \textit{arc's length}\\\\ s=\cfrac{\pi \theta r}{180}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\ \cline{1-1} \theta =135\\ r=11.4 \end{cases}\implies s=\cfrac{\pi (135)(11.4)}{180}\implies s=8.55\pi \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill s\approx 26.86~\hfill$
