The answer is m = 2 and b = -8
because y=mx + b
in the equation above m = 2 because mx=2x
b = -8 because mx+b
plus or minus

Can you answer this question?​
Debora [2.8K]

Answer: y= 3 times 2 to the power x. Second answer

Step-by-step explanation:

if you plug in 0 for x, y= 3x 1= 3

if you plug in 1 for x y= 3 x 2 = 6

Look at the x values and y values

(0,3) and (1, 6) on the graph. It matches answer number 2. Remember, 2 raised to the power 0 = 1 and 3 times 1 = 3. And 2 raised to the power 1 =2 and 3 times 2 = 6.

Find the height of the triangle
Paul [167]
There are two -main- approaches to answer this problem. By using the sine identity, or applying law of sines.

We'll do the sine trig. identity, as it is the most effective.

Given an angle '\alpha' in a right triangle, 'sin( \alpha )' is defined as the opposite side of the triangle to the given angle, over the triangle's hypotenuse.

So, for this setup:
sin(20)= \frac{x}{10}

Now, we solve for x:
x=10sin(20)=3.42

So, answer is 3.4
