Answer:
a line parallel has the same slope and different y-intercept, and the slope of the perpendicular line would be -3/5
Step-by-step explanation:
3x + 5y = 4
5y = -3x + 4
y = -3/5x + 4/5
Answer:
slope of line ax + by = c is -a/b
so, slope of 7x +2y =5 is -7/2
1 inch = 13.5 feet
5 inches = 5 * 13.5 = 67.5 feet
To find the decimal value of a fraction, you simply divide the numerator by the denominator. In this case, we are dividing 4 by 20, which is equal to .2. Therefore, the decimal value that is equal to 4/20 is 0.2.
1.64 / 0.2 = 8.2 I checked it to make sure by multipying: 8.2 * 0.2 = 1.64
