The third set is equivalent to
2x + y = 2
2x + y = -2
clearly inconsistent.
Answer: 3 mph
Step-by-step explanation:
1. 1/2 mph for 1/2 an hour as they said, meaning that they would've walked for 3 miles kn an hour.
2. 4 and 1/2 miles.
3 + 1 2/4. = 4 1/2
3. 1 3/4 hours.
3 + 2.25 = 5.25
3 x .75 = 2.25
3 miles per hour.
(-3,4)(0,-3)
slope = (-3 - 4) / (0 - (-3) = -7/3 <=
Answer:
C.
Step-by-step explanation:
the given graph touches the Y-axis in the point (5;0), it means the only zero.
To the additional: the graph is y=(x-5)².
2x-8(-7-x)=6
2x+56+8x=6
10x=-50
x=-5
y=-7-(-5)
y=-2
(-5,-2)
