Equivalent fractions means both the numerator and denominator must be multiplied with the same number.

15/36

15*2/36*2= 30/72

15*3/36*3=45/108

Hence the fraction are 5/12, 15/36, 30/72, 45/108

For y intercept put x value zero in the equation

-2x - y = -10?

-2(0)-y=-10

-y=-10 multiply both sides by minus

y=10

The values x=0 and y=10

Hence the point be (0,10)

(7x-3)^2i am not getting what you are asking

Its in the form of (a-b)^2=a^2+2ab+b^2

so place the values in the formula,after putting that you get the equation like this 49x^2-42x+9

Hi i think u know the place value chart for units ,tens, hundreds etc.,

Mike explained the correct way if u want to know other method check this

given number was 435,799,030

So first take the number 4 and count the number of digits after 4.It is having  8 digits, so place 8 0's after 4 means 400,000,000
