Answer:
9.125
Step-by-step explanation:
9.25 - 1/2 + 3/8 =
= 9.25 - 0.5 + 0.375
= 8.75 + 0.375
= 9.125
Answer:
k = -18
Step-by-step explanation:
If x-3 is a factor, what this means is that if we substitute;
x = 3 into the equation, we should get 0
This is from the factor theorem
Thus ;
P(3) = 0 = 2(3)^3 -5(3)^2 + 3(3) + k
0 = 54 - 45 + 9 + k
k + 18 = 0
k = -18
X= -4
y= 7
you can multiply the top equation by 3, then both y's are cancelled or zeroed out. You add -21 and 6 to get -15x. Than you add 42 and 18 to get 60. So, -15x=60 and from there you do 60/-15 to get x=-4. Plug in what you got for x into any of the two equations to get y, which is 7.
1 mile = 1.6km.
so
100 miles x 1.6km = 160.
The number of km between two cities is 160km.
