Answer:
x = -6
Step-by-step explanation:
Maybe this means you want to solve ...
-3x -8 = 10
-3x = 18 . . . . . add 8 to both sides
x = -6 . . . . . . . divide both sides by -3
Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.
Yes I’m going back to the sun yet I have a couple questions and I’m not gonna be able I do that but I’m sorry I don’t have a lot to say about to do this but I’m not going back to the sun today or
Answer:
18) 4 * 10 ^ -10
19) t ^ 9
Step-by-step explanation:
18. When multiplying in scientific notation, just multiply the regular numbers together and add the exponents for the tens.
So it'll be 40 * 10^-11
However, the beginning number should have the decimal right after the 4, not any place after (for example, it's 3.056, not 30.56 or 3056.)
To fix this, move the decimal place forward one space from 40. to 4.0, and add 1 to the -11 power.
So the answer is now 4 * 10^-10
19. When dividing exponents, if the base number is the same, you can divide. (Basically, you can not divide x^2 and y^3 because x and y aren't the same)
Since in this case it's t, you can divide.
Dividing exponents is simple: just subtract them.
14 - 5 = 9
so the answer is t ^ 9
the answer is true because 6x multiply -2 to give -12x and 6x multiplies x² to give 6x³
