Answer:
Step-by-step explanation:
First rearrange all equations into this format:
that will result in:
then we'll multiply an equation with a number such that we have same numbers on both equations (with only different signs). So we can add them
Here you can see that we've multiplied the first equation with (-3) so that we have -9x on one equation and 9x on the other. Now when we add the two equations the 9x and -9x terms will cancel out (or eliminate)
now that we've found the value of y
we'll use this value in any of the two equations to get the value of x.
let's put y in the first equation:
Answer:
We want to estimate:
We can rewrite this as:
And √2 is a notable value, we know that:
√2 ≈ 1.41
Then:
then:
is a really good estimation.
if instead:
"the square root of eight divided by two to the second power"
refers to:
is easier, we just can replace 2^2 = 4, then we get:
Is also a really good aproximation.
