Answer:
10 miles per 1/4 hour
40 miles per hour
Step-by-step explanation:
Given that:
A car travels 20 miles in 1/2 hour
Miles traveled per hour :
(20 * 2) / 1 = 40 miles per hour
Mile traveled in 1/4 hour :
Distance = speed * time
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
Car traveling 30 miles in 3/4 hours
(30 * 4) /3 = 120 / 3 = 40 miles per hour
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
The answer is the the second or B
-10x - 15y = -30
-10x + 30 = 15y
(30 - 10x) / 15 = y
(30/15) - (10x/15) = y
2 - 2x/3 = y
Answer: y = -2x/3 + 2 or y = 2- 2x/3
All we need to do is find 20% of 840, subtract it from 840, and divide the remaining by 6.
840×.2=168
840-168=672
672÷6=112

Answer:
(4, - 7)
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 4)² - 7 ← is in vertex form
with (h, k) = (4, - 7 ) ← vertex
