First, if ordered pairs are in the form of (x,y) then the first one means plug in x with 0. If you do that, you get y= -10(0)+18. Simplify to get y=18. So, for the first one, it is (0,18). For the next one, you plug in 1 for x. So, y=-10(1)+18. Simplify to get y=-10+18. Simplify again to get y=8. So the second one is (1,8). For the last one you have only the y value, so plug in 78 for y. So, 78=-10x+18. We want to isolate x, so subtract 18 from both sides. You get 60=-10x. Now divide by -10 to get -6=x. So, the last ordered pair is (-6,78)

Solve the equation. 12=2+z/-6

Bogdan [553]

Answer:

$\boxed{\bold{z=-60}}$

Step-by-step explanation:

Switch Sides

$\bold{2+\frac{z}{-6}=12}$

Subtract 2 From Both Sides

$\bold{2+\frac{z}{-6}-2=12-2}$

Simplify

$\bold{\frac{z}{-6}=10}$

Multiply Both Sides By -6

$\bold{\frac{z\left(-6\right)}{-6}=10\left(-6\right)}$

Simplify

$\bold{z=-60}$

9.) Answer: B. f(x) = 4 - x

Explanation/Proof:

If we substitute, the answers are correct.

f(x) = 4 - (1)

f(x) = 3 ✅

f(x) = 4 - (2)

f(x) = 2 ✅

And so on and so forth.

On a unit circle, the terminal point of 0 is (sqrt3/2,1/2) What is 0?

san4es73 [151]

Answer:

The measure of $\theta$ is 30°.

Step-by-step explanation:

In the statement, the angle has been misrepresented. The corrected statement is described below:

"On a unit circle, the terminal point of $\theta$ is $\left(\frac{\sqrt{3}}{2}, \frac{1}{2} \right)$ . What is $\theta$ ?"

The measure of the angle ( $\theta$ ), in radians, is in standard form, that is, it is done with respect to the +x semiaxis. The measure of the angle whose terminal point is of the form $(x,y)$ is determined by the following inverse trigonometric function:
