Answer:
y=7x + 5
Step-by-step explanation:
sub into y= mx + c
where m = slope/gradient (7)
and c = y-value of y-intercept (5)
You need to find the total distance and the total time. The total distance is two times the distance to school, 2d.s=d/t=>t=d/sWhere s is speed, d is distance and t is time. So the time taken to get to school is:d/s1and the time taken to get back is:d/s2so the total time is:d/s1+d/s2=d(1/s1+1/s2)So, as speed = distance/time, divide the total distance by the total time:2d/d(1/s1+1/s2)=2/(1/s1+1/s2)=2/(1/20+1/40)=80/3≈26.7km/hr
We are asked to determine the product of square root of 2 and 3 square root of 2 + square root of 14. In this case, we can use the calculator directly to find the answer to the given problem. The answer is A.12. we can also multiply 2 to the numbers under the radical and then simplify to get 12, nonetheless
