Answer:
5(a+b)
Step-by-step explanation:
5(a)+5(b)
5(a+b)
Answer:
Step-by-step explanation:
Step 1:
t+8*4
Now put the value t=2
Step 2:
2+8*4
According to the DMAS rule multiplication will be solved first:
Step 3:
=2+32
Now add the terms:
Step 4:
=34....
The slope-intercept form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
substitute the coordinates of the points (8, 0) and (20, 12) to the formula:
![m=\dfrac{12-0}{20-8}=\dfrac{12}{12}=1](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B12-0%7D%7B20-8%7D%3D%5Cdfrac%7B12%7D%7B12%7D%3D1)
y = 1x + b = x + b
Put the coordinates of the point (8, 0) to the equation of a line:
0 = 8 + b <em>subtract 8 from both sides</em>
-8 = b
<h3>Answer: y = x - 8</h3>
Answer:
π
Step-by-step explanation:
The *period* of a function is the length it takes before it repeats. Usually, the period of the sine function is 2π; it takes a full rotation around the unit circle for it to repeat. When we replace the input x with -2x, this does a few things:
- Changes the rotation direction
- Makes the rotation go twice as fast
If we rotate around the unit circle twice as fast, it’ll take us half of 2π, or just π to complete a cycle.
