Answer: y = 0.45x + 21
Step-by-step explanation:
let x represent the number of minutes used in a month.
Let y represent the monthly cost for x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (304.5 - 183)/(630 - 360)
m = 121.5/270 = 0.45
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = y intercept
m = slope
To determine the y intercept, we would substitute x = 360, y = 183 and m = 0.45 into y = mx + c. It becomes
183 = 0.45 × 360 + c
183 = 162 + c
c = 183 - 162
c = 21
The equation for the monthly cost is
y = 0.45x + 21
Answer:
5 times the square root of 3
Step-by-step explanation:
To get the longest side of a 30-60-90 triangle, you take the shortest side and multiply it by the square root of 3.
5*(square root of 3)

Answer:
About 34
Step-by-step explanation:
There are 168 chocolate chips in 5 ounces. That means you want to know how many chips there are per ounce. Divide 168 by 5 and you get approximately 34 chocolate chips per ounce (33.6 if you need this)
The graph that shows y=3⌈x⌉ + 1 from the given options is the<u> Third graph </u>as shown attached.
<h3>Which graph shows the function best?</h3>
The third graph shows the function and this can be tested as follows:
When x = 2, y = 7:
y = 3x + 1
= 3 x 3 + 1
= 7
When x = 3, y = 10:
y = 3 x 3 +1
= 10
When x = 1, y = 4
y = 3 x 1 + 1
= 4
This shows that the line on the third graph is well represented by the function, y=3⌈x⌉+1.
