20/100 = 0.20
0.20 * 9 = 1.8
9 - 1.8 = 7.2
The sale price of the DVD is $7.20.
Answer:
Step-by-step explanation:
60 -1 1/2 (8) 2
= 60 - 3/2 (8)(2)
= 60 - 3(8)
= 60 - 24
= 36
Answer:
9526/87
Step-by-step explanation:
87·x=9,526
x=9526/87
Answer:
Step-by-step explanation:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and b is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named as the "slope-intercept form".The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y.
The slope m of this line shows its steepness, or slant - It can be calculated like this:
m = change in y-value /change in x-value
The equation of any straight line, called a linear equation, can be written as: y = mx + b ....
answer = not define
Step-by-step explanation:
slope = (y2- y1) / (x2- x1)
= 9-3 / 7-7
= 6/0
