I’m not very good at math but here’s my reasoning:
x/2-7=9
I moved the 7 to the other side of the equation
So now
X/2 = 9 + 7
X/2 = 16
Since x is equal 16 if you divide x by 2 (because x/2=16), that means if you want to find x you need to multiply x by 2
X = 16 x 2
X = 32
I hope it’s right !! <3
Answer:
56°
Step-by-step explanation:
Using the sine ratio in the right triangle, that is
sin ? =
=
, then
? =
(
) ≈ 56° ( to the nearest degree )
to get the slope of it, we simply need two points off the table, say (-4,-114) and (2,48). Recall that the y-intercept, where the graph <u>intercepts</u> the y-axis, when that happens x = 0, so is right there on the table already.

![\bf slope\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{48-(-114)}{2-(-4)}\implies \cfrac{48+114}{2+4}\implies \cfrac{162}{6}\implies 27 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \left(\stackrel{slope}{27}~~,~~\stackrel{y-intercept}{-6} \right)~\hfill](https://tex.z-dn.net/?f=%5Cbf%20slope%5Cimplies%20%5Ccfrac%7B%5Cstackrel%7Brise%7D%7B%20y_2-%20y_1%7D%7D%7B%5Cstackrel%7Brun%7D%7B%20x_2-%20x_1%7D%7D%5Cimplies%20%5Ccfrac%7B48-%28-114%29%7D%7B2-%28-4%29%7D%5Cimplies%20%5Ccfrac%7B48%2B114%7D%7B2%2B4%7D%5Cimplies%20%5Ccfrac%7B162%7D%7B6%7D%5Cimplies%2027%20%5C%5C%5C%5C%5B-0.35em%5D%20%5Crule%7B34em%7D%7B0.25pt%7D%5C%5C%5C%5C%20~%5Chfill%20%5Cleft%28%5Cstackrel%7Bslope%7D%7B27%7D~~%2C~~%5Cstackrel%7By-intercept%7D%7B-6%7D%20%5Cright%29~%5Chfill)
