Answer:
Step-by-step explanation:
we have to find the dot product here.
From the formula of dot product of vectors,
we know-
if X=<a,b,c> and Y=<d,e,f>
Then dot product of X and Y is-
X.Y=ad+be+cf
Here, we get
v=<2 , -8 , -8>
and w=<-2 , 6 , -5>
So, the dot product is-
v . w=2(-2)+(-8)(6)+(-8)(-5)
=-4-48+40
=-52+40
=-12
So,
v . w= -12
Slope intercept: y = mx + b
Y = 9x + b, plug in point
9 = 9(0) + b, b = 9
Solution: y = 9x + 9
Answer:
30
Step-by-step explanation:
Answer:
1200
Step-by-step explanation:500-200=300
1250-500=750
750-300=450
750+450=1200
5/35 so 1/7 as a decimal this is .143. This is because it says D OR F which means add them and divide by 35. So your answer is 0.143
