Answer:
Plug in your variables value.
Step-by-step explanation:
For your case, plug in -6 into the y slot
12(5+2y)= -(6-9y) +4y
12(5+2x-6)= -(6-9x-6)+4y see if that works!
Answer:
There are 16 rows of seats in the auditorium.
Step-by-step explanation:
Jose is correct in writing out 416 = 2x² - 6x.
Rewriting this in descending order by powers of x, we get:
2x² - 6x - 416 = 0
Dividing all four terms by 2 simplifies this equation to x² - 3x - 208 = 0. This equation, in turn, factors to (x + 13)(x - 16) = 0. The only reasonable answer is x = 16. Jose's solutions are incorrect.
There are 16 rows of seats in the auditorium.
The number of seats per row is 416/16, or 26.
There is no triangle below. Try to edit this problem.
Draw the picture; you have a right triangle. The guy wire is the hypotenuse
You want the length of the base when the side opposite the 41 degree angle
is the tree.
You have an angle and the hypotenuse; the base is the side adjacent to the
41 degree angle.
EQUATION:
cos(41) = adjacent/hypotenuse = x/14
14cos(41) = x
x = 10.57 ft
