"20% off regular price" can be calculated by multiplying the regular price by (1.00-0.20), or 0.80. Thus, the discounted price will be 0.80($120), or $96.
The common difference is -5
right now, a₁₂ = 22
to get a₁, subtract 5 each time you subtract one from the subscript
so
a₁₁ = 17
a₁₀ = 12
a₉ = 7
a₈ = 2
a₇ = -3
a₆ = -8
a₅ = -13
a₄ = -18
a₃ = -23
a₂ = - 28
a₁ = -33
a₁ = -33
hope this helps
The slope of the lines is -0.75 and 0.75 respectively. This shows that the slope of one of the<u> line is negative of the other.</u>
<h3>Slope of a line</h3>
The slope of a line is the rate of change of the y-axis of the coordinate to x-axis. The formula for calculating the slope of a line is expressed as;
Slope = y2-y1/x2-x1
Given the following coordinate point (−8, 9) to (−4, 6), the slope is calculated as;
Slope = 6-9/-4+8
Slope = -3/4
For the coordinate points (-4, 6) and (2, 1.5), the slope is calculate;
Slope = 1.5-6/2+4
Slope = -4.5/6
Slope = 0.75
Hence the slope of the coordinate point is 0.75.
Hence the slope of the lines is -0.75 and 0.75 respectively. This shows that the slope of one of the<u> line is negative of the other.</u>
