Answer:
The answer is 15
Step-by-step explanation:
-5 + 2(10)
-5+20
=15
5,175 + 9% = <span>5640.75
</span>5640.75 - 5% = <span>5302.305
</span>
Original investment = 5,175
Gain = 5,302.305
Subtract them both and get = <span>127.305</span>
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:
x>6
