Answer:
x = 3
Step-by-step explanation:
y =4x - 2
4 x 3 = 12
Solution for what is 147.1% of 155
155/x=100/147.1
(155/x)*x=(100/147.1)*x - we multiply both sides of the equation by x
155=0.67980965329708*x - we divide both sides of the equation by (0.67980965329708) to get x
155/0.67980965329708=x
228.005=x
x=228.005
now we have:
147.1% of 155=228.005
You are correct. 4 is the slope and 2 is the y intercept.
Reasoning:
y = mx + b is the slope intercept form of a line
m stands for slope
b stands for y intercept
In your case, m = 4 and b = 2.
For this case we evaluate the function when x = 0
We then have to evaluate:
y = -2sinx - 1
y = -2sin (0) - 1
y = -1
Then, the intersection with the y-axis is -1 and the amplitude is 2.
Answer:
y = -2sinx - 1
option 2
First I subtract the 3, then if you have 3 left and you take away 2/5 you're left with 2 3/5. hope this helped
