Answer:
60 km/hr.
Step-by-step explanation:
When Dad caught up the the time he had been driving was 4 hours and the time Mom had been driving was 1 + 4 = 5 hours.
They both drove the same distance, d km.
For Dad:
speed = d / time
75 = d / 4
d = 75 * 4 = 300 km.
Mom took 5 hours to travel this distance, so
Mom's speed was 300 / 5 = 60 km/hr.
Y = -3x + 5
When creating a line in slope intercept form, the -3 always goes right next to the x after the equals sign. Also, the y intercepts y value (the second part of the parenthesis) just gets added on at the end of the equation.
Answer:
C 40 inches
Step-by-step explanation:
You can use the pythagorean theorem to solve for the second leg. When you plug in 42 for a and 58 for c, you get 42^2 + b^2 = 58^2, then you can isolate b, which should be 40 inches.
Answer:
The choose (D)
D. Translate y = |x| up 4 units and shade inside the V.
Answer:
it's B
Step-by-step explanation:
the easiest why to tell is that, the slope intercept form y=mx+b is the form the equations are b is the y-intercept. If you look at the graph it crosses y at +16 not -16
