The equation is 
\sqrt{2x-7}=7\\\text{Elevating to 2 the two sides of the equation we get:}\\2x-7=49\\\text{Therefore:}\\2x=49+7=56\\x=\frac{56}{2}=28\\\text{Solution : }x=28

Find the area of the rhombus. Leave your answer in simplest radical form.
kati45 [8]

Answer:

162√3.

Step-by-step explanation:

Area = 1/2 * p * q  where p and q are the diagonals.

Here p = 2*9 = 18 and we need to find q.

tan 60 = 0.5q/9

0.5q = 9 tan 60 = 9*√3

q = 18√3

So the area of this rhombus

= 1/2 * 18*18√3

= 162√3

The slope of the line shown in the graph is ? and the y intercept of the line is ?
ohaa [14]
Pick 2 points on ur line and use the slope formula : (y2 - y1) / (x2 - x1)

(y2 - y1) / (x2 - x1)
(-9,0)....x1 = -9 and y1 = 0
(0,6).... x2 = 0 and y2 = 6
now sub
slope = (6 - 0) / (0 - (-9) = 6/(0 + 9) = 6 / 9 = 2/3 <==

ur y intercept is where ur line crosses the y axis...and that would be (0,6)....or just 6 <==
