Step-by-step explanation:
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:
<em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>garden</em><em>=</em><em>1</em><em>2</em><em>1</em><em> </em><em>square</em><em> </em><em>meter</em>
<em>perimeter</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>garden</em><em>=</em><em>4</em><em>4</em><em> </em><em>meter</em>
Step-by-step explanation:
Area of a square=side*side
=11*11
=<u>1</u><u>2</u><u>1</u><em><u>s</u></em><em><u>q</u></em><em><u>u</u></em><em><u>a</u></em><em><u>r</u></em><em><u>e</u></em><em><u> </u></em><em><u>meter</u></em>
Perimeter of a square garden=side*4
=11*4
=44 m
