Answer:
20
Step-by-step explanation:
n(A) only =15-4=11
n(B) only=9-4=5
n(A n B)=4
n(A U B)=11+5+4=20
Answer: y = 1/3x +2
Step-by-step explanation:
The equation of line in slope - point form is given as:
y - = m ( x - )
m = 1/3
= 0
= -6
substituting into the formula , we have
y - 0 = 1/3 ( x - {-6} )
y = 1/3 (x+6)
y = 1/3x +2
Answer:
x= -15/8
Step-by-step explanation:
5(2x+3)-2x = 0
10x+15-2x = 0
8x= -15
x= -15/8
Well, if 1 mile = 1.6 kilometers and he's traveling at 18mph, then do 18 x 1.6 which = 28.8.
So, this is his current speed in kph
3 x 28.8 = 86.4
They will have traveled 86.4 kilometers
(I haven't worked with this kind of math in a while so correct me if I'm wrong!)
