Answer:
Step-by-step explanation:
Add you like terms. 4x plus 4x equals 8x. Then 5 plus 9 equals 14 so then you have 8x= 14 divide by eight on both sides and there you go.
Answer:
A
Step-by-step explanation:
we can find using the trigonometric formulas
we can find y by using cosine.
cos = adj / hyp
cos 60 = y / 10
y = 10 cos 60
y = 5
now we can use the Pythagorean theorem since we have the base and hyp
a² + b² = c²
5² + b² = 10²
25 + b² = 100
b² = 75
b = 5√3
K(x) = 5x-6
(k+k)(x) = k(x) + k(x) = 5x-6 +5x-6
just plug in x = 4,
(k+k)(4) = 5(4) -6 + 5(4) -6
thats your answer, the last option.

Answer:
![9x- 60=10](https://tex.z-dn.net/?f=9x-%2060%3D10)
Step-by-step explanation:
Given
![\frac{3}{4}x - 5 = \frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dx%20-%205%20%3D%20%5Cfrac%7B5%7D%7B6%7D)

The denominators in the above expression are 4 and 6.
So, first we take the LCM of 4 and 6
![LCM = 12](https://tex.z-dn.net/?f=LCM%20%3D%2012)
Next, multiply both sides of the equation by this LCM (12)
![12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12](https://tex.z-dn.net/?f=12%20%28%20%5Cfrac%7B3%7D%7B4%7Dx%20-%205%29%20%3D%20%5Cfrac%7B5%7D%7B6%7D%20%2A%2012)
![12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12](https://tex.z-dn.net/?f=12%20%2A%20%5Cfrac%7B3%7D%7B4%7Dx%20-%2012%20%2A5%20%3D%20%5Cfrac%7B5%7D%7B6%7D%20%2A%2012)
