Answer:
Step-by-step explanation:
Y=3x-4
Slope of this line = 3
Slope of the line parallel to this line = 3 {slope of parallel lines are equal}
Slope of the line perpendicular to this line = -1/3 {product of the slope of perpendicular lines= -1}
Answer:
11.413 Hours.
Step-by-step explanation:
Alicia can paint a house in 21 hours; Which means in 1 hour she can paint 1/24 of the house.
Nina can paint the same house in (21+4) hours. Which means in 1 hour she can paint 1/25 of the house.
Together in 1 hour they can paint: 1/21 + 1/25 = 46/525 of the house.
Total Hours for painting the house together will be 525/46 = 11.413 Hours.
Answer:
=360x
Step-by-step explanation:
Answer:
y = 5(x - 3)² + 2
Step-by-step explanation:
y = a(x - h)² + k
y = a(x - 3)² + 2
7 = a(4 - 3)² + 2
a = 5
y = 5(x - 3)² + 2
