7x+5=-9
Subtract 5 on both sides
7x=-14
Divide 7 on both sides
X=-14/7=
-2
Answer:
<h2>34.88feet</h2>
Step-by-step explanation:
The set up forms a right angle triangle with the length of the ladder being the hypotenuse and the angle of elevation is 29.32°. USing SOH, CAH TOA to determine the distance of the building from the base of the ladder.
The distance we are looking fir will be the adjacent. According to CAH.
cos29.32°= x/40
x = 40cos29.32°
x = 34.88feet (to the nearest hundredth)
The ladder is 34.88feet away from the building
Answer:
the zero of a function is the value of x which makes the final value zero
First Equation:
So let 25 - 2x equal to 0
<em>25 - 2x = 0</em>
x = 12.5
Second Equation:
Let 2x² - 11x - 6 equal to zero
<em>2x² - 11x - 6 = 0 </em>
<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>
<em>2x(x - 6) + 1(x - 6) = 0</em>
<em>(2x + 1) (x - 6) = 0</em>
So we can transpose either one of the brackets below the zero
(2x + 1) = 0 or (x-6) = 0
x = -1/2 or x = 6
