Step-by-step explanation:
( y = 4x/5 + 2)
m1.m2 = -1
4/5.m2 = -1
m2 = -5/4
formula = y - y1 = m2 ( x - x1)
y - 3 = -5/4 ( x - 6)
y -3 = -5x /4 + 30/4
y = -5x /4 + 21/2
Answer:
A.) y = 20x
B.) 21 minutes
Step-by-step explanation:
y = mx + b; y2 - y1/ x2 - x1 = m (slope)
A.) If a factory can build 20 cars per hour, the first point would be (1, 20). To find the slope (m), divide the y-axis by the x-axis: 20/1 = 20.
B.) Before we can do this problem, we must first convert the hours to minutes. 1 hour = 60 minutes. Then we divide the minutes by the number of cars. 60 ÷ 20 = 3. That means the factory builds 1 car every 3 minutes. Multiply the number of cars, 7, by the number of minutes it takes to make one car: 7 • 3 = 21.

Pair 2 is a reflection. If you rotated it it would be flipped, so that doesn’t make sense.
C=(-4,-6)
D=(1,-6)
lCDl=√(1-(-4))²+(-6-(-6))²
lCDl=√(1+4)²+(-6+6)²
lCDl=√5²+0²
lCDl=√25
lCDl=5
the distance between the CD points is 5
