Answer:
C) 4/15
Step-by-step explanation:
The two equations ...
- 2x + 1/2y = 2
- 1/2x + 2y = 6
can be solved for x using Cramer's rule:
x = (2·2 -1/2·6)/(2·2 -1/2·1/2) = (4-3)/(4-1/4) = 1/(15/4)
x = 4/15
_____
Cramer's rule for the solution to ...
is ...
- ∆ = ae-db
- x = (ce -fb)/∆
- y = (fa-dc)/∆
All the other stuff, east/west, doesn't matter.
He drives 3 miles north, then later on he drives 4 more miles north:
3 + 4 = 7
The dog show is 7 miles north of his home.
Answer:
Step-by-step explanation:
Exponents are basically just saying how many times the number is multiplied by itself.
In the expression 
, we can see that 10 is being multiplied by itself 5 times.
So the exponent becomes 5, and the base is 10.
.
Hope this helped!
We write the expression:
((2 ^ (1/2)) * (2 ^ (3/4))) ^ 2
We use for this case the properties of lso exponents:
((2 ^ (1/2)) * (2 ^ (3/4))) ^ 2
((2 ^ (2/2)) * (2 ^ (6/4)))
((2 ^ (1)) * (2 ^ (3/2)))
((2 ^ (1 + 3/2))
((2 ^ (5/2))
answer:
((2 ^ (5/2))
option 2
9.50h+60=460
subtract 60 from both sides
9.50h=400
divide both sides by 9.50
h=<span>42.105263
</span>round to the nearest hundredth
h=42.11<span>
