Three consecutive integers have a sum of –21. Which equation can be used to find the value of the three numbers? x + x + x = neg
Jet001 [13]

Answer:

The equation which can be used to find the value of numbers

(x) + (x + 1) + (x + 2) = - 21

Step-by-step explanation:

Let the first no. is =  x

Second number = x + 1

Third number = x + 2

The sum of three consecutive numbers = x + x + 1 + x + 2

Given that Three consecutive integers have a sum of –21.

Therefore

(x) + (x + 1) + (x + 2) = - 21

This is the equation which can be used to find the value of numbers.

<h3>A.</h3>

See below for a graph

<h3>B.</h3>

The inverse of a function appears on a graph as the reflection of the function across the line y=x. This is because the inverse relation is effectively the same relation with the variables x and y swapped. Here, the graphs of f(x) and g(x) are mirror images of each other across the line y=x, so we can see they are inverse functions.

The same technology allows us to graph y=f(g(x)) and y=g(f(x)). Both are graphs of y=x, as expected.

+(-6) + (-8)= -4<br> What’s the missing number???
Darya [45]

Answer:

10

Step by step explanation:

In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.

Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."

x + (-6) + (-8) = -4

x + (-6 + -8) = -4

x + (-14) = -4

x + (-14 + 14) = -4 + 14

x = 10
