40 km - meters is 40 * 1000 whch is 40000 meters per hour
Answer:
point slope: y-7=2(x-4
slope intercept: y=2x-1
Step-by-step explanation:
point slope form: y-y1=m(x-x1)
(4,7) and m=2
using all the info here is it in point slope form: <u>y-7=2(x-4)</u>
turning the point slope equation into slope intercept...
slope intercept form: y=mx+b
first simplify y-7=2(x-4) into y-7=2x-8
then add 7 to both sides...
which would be <u>y=2x-1 </u>
and thats your answer!!
I hope you might have understood.
Answer:
Step-by-step explanation:
Letters are variables and those variable can store a number
Ex: x=5 y=2
evaluate : 3x+2y
we know that x is 5, so we know that 3x would be 15
we know that y is 2, so we know that 2x would be 4
then it says to add 3x and 2y, we would add 15 and 4 to get 19
(This is a very simple example, when you get older, the expression would be much more confusing.
