What expression is not equivalent to 1/343 A. 7-1 x 7-2
B.77 x 7-10
C. 7-2 x 7-5
D. 7-5 x 72
(All expressions have an Integer either negative or positive u just can't type it correctly here and B and D or not 77 or 72 it's 7 and positive 7 and D is 7 positive 2

Answers

Answer 1

Answer: 1 / 343
This is just equal to
1 / 7^3 = 7^-3

A. 7^-1 * 7^-2 = 7^(-1 + -2) = 7^-3
B. 7^7 * 7^-10 = 7^( 7+ -10) = 7^-3
C. 7^-2 * 7^-5 = 7^(-2 + -5) = 7^-7
D. 7^-5 * 7^2 = 7^(-5 + 2) = 7^-3

So the correct answer is letter C. 7^-2 * 7^-5

Subtract 8.263 from 13.48, you obtain

Answers

Hey There!

Steps to solve (Steps will be in numerical order)

1. Set up the equation 13.480-8.2633.

2. Since you have to subtract from left to right, First subtract 10-3=7, you get the 10 because you have to regroup, regrouping means taking away from tens . Since you regrouped 0, you have to take away one number from 8, so now you have to solve 7-6=1, next is 4-2=2, you have to solve 3-8 now, since you cant subtract 3-8, you regroup and change 3 to 13, now you are solving 13-8 which equals to 5, next since you regrouped you subtract 1-1 which equals zero.

In conclusion, 13.480-8.263=5.217

True or False. A function's graph may include solutions that do not appear in its table of values.

Answers

Yes it is true that a functions graph always include solutions that do not appear in its table of values.

What is a function?

An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -

f(x) = 4x + 6

Given is a graph of function.

Yes a functions graph always include solutions that do not appear in its table of values. The graph of the function represent all the points that satisfy the function on both sides. The table of values is made just to represent only some of the solutions from the total solutions.

Therefore, yes it is true that a functions graph always include solutions that do not appear in its table of values.
