Answer:

Step-by-step explanation:

To solve for <em>x</em> you first isolate the variable you want on one side. We will do this by using PEMDAS and expanding our terms fully first before we move our terms around.

$-2(x-4)=10x+2\\-2x-8=10x+2$

We then isolate our term, remember to add numbers and variables to both sides so you aren't changing the value of the equation, and solve for <em>x.</em> $-2x-8=10x+2\\-2x-8-2+2x=10x+2-2+2x\\-10=12x\\\frac{-10}{12}=x\\\frac{-6}{5}=x\\-1.2=x\\$

Answer:

Step-by-step explanation:

-2(x-4) =10x+2

-2x--8= 10x+2

-2x+8= 10x+2

-2x+10x= 8+2

8x= 10

x= 0.8

As θ increases, the value of cos θ increase, decreases or stays the same?

icang [17]

Answer:

As θ increases, the value of cos θ decreases

Step-by-step explanation:

As as θ increases, the value of cos θ decreases from 1 to -1 in the first two quadrants ( between 0 and 180 degrees). Cos(0) = 1, cos(90) = 0, cos(180) = -1.

On the other hand, as θ increases from 180 to 360 degrees (last two quadrants) the value of cos θ increases from -1 to 1.
