Venus is the planet that comes nearest to the earth its closest position is about 38000000 kilometers from earth. write this number expressed as a product of 38 and a power of 10.

always put the 1st number you would like to turn to scientific notation

so the 1st number here is 3

then you turn 8 into a decimal because it is the only other number that isnt 0 and then it is 3.8

you then count every number after 3 including 8 which is

then you always put 10 x whatever number you are doing but right now it is 3.8

and the answer is

10 x 3.8^7

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
