Answer:
Step-by-step explanation:
-20z+8+(-6)
-20z+2
So our two equations are y=-8x-4 and y=-16, and since in both equations, something equals the same y, those two are the same. So we can combine the two into -16=-8x-4. In the question, they are asking to solve for x. So to do that, you need to isolate your variable. Now for solving algebraic equations, you use reverse PEMDAS (SADMEP), meaning you add 4 to both sides to clear the -4 one the rights side to get -12=-8x. Then you divide both sides by -8 to get 12/8, which simplifies to 3/2.
Answer: Its 4
Step-by-step explanation:
- Okay so 2+2 is just saying like your adding 1+1+1+1 and that gives you four.
- They're is another way you can get the sum too, You just add 2 to the number 2.
Answer:

Step-by-step explanation:
We are given that:

Where <em>A</em> is in QI.
And we want to find sec(A).
Recall that cosecant is the ratio of the hypotenuse to the opposite side. So, find the adjacent side using the Pythagorean Theorem:

So, with respect to <em>A</em>, our adjacent side is 63, our opposite side is 16, and our hypotenuse is 65.
Since <em>A</em> is in QI, all of our trigonometric ratios will be positive.
Secant is the ratio of the hypotenuse to the adjacent. Hence:

Answer: -2
Step-by-step explanation:
f(-2) = -2
It is the value of y when x = -2. I read "-2."
