The sum<br> of three consecutive integers is - 126. What are the integers?
Leno4ka [110]
Let the three consecutive integers be x , x+1 ,x+2
Given, sum of three consecutive integers = -126
x +x+1+ x+2 = -126
3x +3 = -126
3x = -126 -3
3x = -129
x = -129/3
x = - 43
x +1 = -42
x +2 = -41

frosja888 [35]

Answer:

  • 0.013
  • 1.3×10^(-2)

Step-by-step explanation:

Many calculators use "E" to signify "×10^( )". Thus ...

... 1.3E-2 = 1.3×10^(-2)

This number in scientific notation is equivalent to the standard form number ...

... 1.3×0.01 = 0.013

For the function f defined below, what is the value of f(-1)? fx=x+3<br> -----<br> 2
Pepsi [2]

Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

- 1 =  \frac{x - 3}{ 2}

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

- 2 = x - 3

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

1 = x

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

<h3>(IN THE PICTURE ATTACHED)</h3>

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

<h3>Since the final coordinates are 3/3 and it simplifies, the final answer is 1.</h3>
