So
Sam has x-2
Answer:
8.17 * 10^8
Step-by-step explanation:
Saturn is 9.1 * 10^8 miles from the sun, and earth is 9.3 * 10^7 miles from the sun. From this, we can see that Saturn is much farther from the sun than the earth.
To find the distance of one planet closer to the sun than the other planet, we can subtract 9.3 * 10^7 from 9.1 * 10^8.
Original expression: 9.1 * 10^8 - 9.3 * 10^7
Convert both sides to 10^7: 91 * 10^7 - 9.3 * 10^7
Subtract: 81.7 * 10^7
Simplify: 8.17 * 10^8
Let me know if this helps!
Answer:
x = -8
Step-by-step explanation:
Distribute on both sides
combine constants
combine variables
then divide
Converse (switch p and q)
If an angle is obtuse, then it measures 128°
This is false (a 127° angle is obtuse, but it does not measure 128°)
_____________________________________________________________
Inverse (negations of p and q)
If an angle does not measure 128°, then it is not obtuse
This is false (a 127° angle does not measure 128°, but it is obtuse)
_____________________________________________________________
Contrapositive (negations of p and q, then switch their places)
If an angle is not obtuse, it does not measure 128°
This is true (any 128° is obtuse; no exceptions)
Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
