So what are u trying to say here. She read in 1/20 of what, minutes, seconds, or what
Answer:
x + y = 2
y = 2 - x
so it is a linear equation.
2x + 5 = 11
2x = 11 - 5
2x = 6
x = 3
it is not a function because for just one <u>x</u> we have many <u>y</u>
Answer:
First it says that you have to multiply the number x times 2, this will give you 2x as a result. Next you have to build your equation which is 2x=10, when you have an equation like this, you divide the result with the number before x (x=10÷2) your result will be x=5. Now you have to square the result (which is x) to get y, when squaring a number you have to multiply it by itself (depending of how many times it's asking to do so when there's a small number at the upper right corner of your number, that's how many times you multiply it) so if you have to square 5, it should be 5×5 which gives you the result of y being 25.
Well not sure what you are asking, but If it is what I think it is, it would go like this:
2
(9^2)
Then the answer should be
9^4 since we multiply the exponents.
If you mean this...
3^2....It would be same as 3 x 3 which we should know is equal to nine.
Hope I helped! (Be sure to thank me!)
