The hundredths place is the second digit to the right of the decimal point. In this case, it's 7. When rounding, we want to look at the number in the thousandths place, or 3.
If the number is 0 to 4, you round the hundredths digit down to remain the same. If the thousandths digit is 5 to 9, you round up a number.
In this case, since the number is 3, we just keep 7 the same. So, the answer would be:
9.97
I'm going to assume that you want to know whether the coordinate satisfies the equation. Let's find out;
-3х - 6у = 17
-3(6) - 6(3) = 17
-18 - 18 = 17
-36 ≠ 17
The point (6, 3) does NOT satisfy the equation.
Best of Luck!
Answer:
and 
Step-by-step explanation:
We have the following system of equations:
and 
To solve the problem, we need to equal the two equations:
⇒ 
⇒ 
⇒ 
So you need to find two numbers that added equal to 5 and multiplied equal to 4. These two numbers are 
and 
.
Then, the factorized form of the polynomial is: 
.
The, the solution to the system of equations is: and .
Answer: 20 minutes.
Explanation:
Think of the water stream as being still (perhaps like a solid pavement), from the point of view of objects floating on the surface. (of course, from the POV of anyone standing on the banks, the water flows downstream). Think of the boat as a bike riding on the pavement. The boat just turned upstream and the hat fell into the water. In this POV, the hat lies on the surface and the boat/bike is riding away. For 20 minutes. Then (Katya realizes she lost the hat and turns back), the boat/bike needs exactly the same time, i.e., 20 minutes to come back to the hat, which rests at the same spot on the surface!
What makes the question initially confusing is the fact that the river flows with respect to the banks and one's mind is tempted to view the situation from there, which makes it much more complicated.
In physics this is referred to as choosing the suitable "frame of reference."
