Scientific notation is a number greater than 0 and less than 10 multiplied by 10 to a power. The expression will be equal to the number given.
91007500
We move the decimal place first so that the number is within our range:
9.1007500
Then we count how many places we moved the decimal. In this case we moved it to the left 7 times, so our exponent of 10 will be 7
Therefore in scientific notation it is 9.1007500 x 10^7
Some teachers prefer to have scientific notation rounded off to the nearest 10th place, so that would be:
9.1 x 10^7
Answer:
-4(-7/30)-3/5=1/3
4(-1/15)+3/5=1/3
Step-by-step explanation:
1. -4x-3/5=1/3
-4x=1/3+3/5
-4x=14/15 <- divide both sides
x= -7/30
2. 4x+3/5=1/3
4x=1/3-3/5
4x= -4/15 <-divide both sides
x= -1/15

Answer:
y=1x+-3
Step-by-step explanation:
using rise over run we can see that we go up one from a point and over 1 from a point making our slope 1. then you you find the y-intercept and here that is very easy because we can clearly see the line pass through -3 on the y axis. the just substitute in your values to get y=1x+-3
