He spoke to each friends for 26 minutes
How I found out : how I found out is that all you have to do it get the total amount which in this question it is going to be 182. And you would need to dive 182 by 7 to find the unit rate (182/7) which is going to equal 26.which means he called each friend for 26 minutes
Answer:
Y = (5/2)x + 3
Step-by-step explanation:
First, we need to make a couple of things clear:
A <em>linear equation</em> has no powers, meaning it makes a straight line.
<em>Slope-intercept</em> form is y = mx + b, where m is the slope, x is, well, x, and b is the intercept.
y and x will both remain as variables in our final solution.
That all said, now we just need to plug in what we were given.
Y = (5/2)x + 3, since our slope is 5/2 and our intercept is 3.
Hope this helps! Now anything you plug in as x will tell you the y-value on this specific line.
Answer:
Amplitude = 3
Step-by-step explanation:
The amplitude of a sinusoidal function is HALF of the difference between MAX and MIN points of the graph.
The graph shown isn't centered at x-axis. Now, we look where the maximum point is. Each unit of graph is "1" units.
The max point is at y = 1
Now, we look for minimum point. Thus,
the min point is at y = -5
The vertical distance is:
1 - (-5) = 1 + 5 = 6 units
The amplitude is HALF of this vertical distance, so
Amplitude = 6/2 = 3
Amplitude = 3
