Eight below zero would express the value -8, negative eight,
but not 8.
Answer:
5 km.
Step-by-step explanation:
We have to calculate the distance if we apply the speed formula that would be the distance in a given time:
v = d / t
therefore, if we solve for distance it would be:
d = v * t
Now the speed is 6 km / h but the time must be calculated, it leaves at 9:15 and returns at 10:05, that is, there is no exact time but 50 minutes, one hour equals 60 minutes, therefore:
50 min * 1 h / 60 min = 0.833 h, that is, the child took 0.833 hours to get to school, now if we replace:
d = 6 * 0.8333
d = 5
In other words, the distance between the school and the house is 5 km.
Answer: 2
Step-by-step explanation:
m = y2 - y1 / x2- x1
where slope is m,
so in this case it would be
m= 1-(-1) / 3-2
m=2/1
m=2
Note that you can do it either way
Answer:
hello :
Step-by-step explanation:
f(x) = 2x²+5√(x-2)
f(x) exist : x - 2 ≥ 0 : x ≥ 2
The domain for f(x) is all real numbers "greater" than or equal to 2
Here is how to work 2, 3 , and 4.
