Is X-13=x+1 true or false

Black_prince [1.1K]

Answer: FALSE.

Step-by-step explanation:

Given the following equation provided in the exercise:

$x-13=x+1$

You need to solve for the variable "x".

In order to solve for "x" you can folllow the steps shown below:

1. You must apply the Addition property of equality and add 13 to both sides of the equation. Then:

$x-13+(13)=x+1+(13)\\\\x=x+14$

2. Finally you need to apply the Subtraction property of equality and subtract "x" from both sides of the equation. So you get:

$x-(x)=x+14-(x)\\\\0=14\ (FALSE)$

Therefore, as you can observe, the given equation has no solutions.

Wendall designs a tower with a height in feet that can be represented by the function T(x) = 9(x + 6.9), where x is the height o

Vinil7 [7]

Answer:

$G(T(x)) = 27(x + 6.9)$

Step-by-step explanation:

Given

$T(x) = 9(x + 6.9)$

$G(x) = 3x$

Required [Missing from the question]

G(T(x))

We have:

$G(x) = 3x$

This implies that:

$G(T(x)) = 3(T(x))$

Substitute: $T(x) = 9(x + 6.9)$

$G(T(x)) = 3[9(x + 6.9)]$

Open bracket

$G(T(x)) = 27(x + 6.9)$

You have two exponential functions. One function has the formula g(x) = 5 ^x . The other function has the formula h(x) = 5^-x .

Shkiper50 [21]

We are given with two functions here: h(x) is 5^-x and g(x) is 5^x . we are asked in the problem to determine the value of the expression (g-h)(x). In this case, we just have to employ subtraction to the given functions. That is

(g-h)(x) = 5^x - 5^-x
= 5^x -1/5^x
= (5^2x -1)/5^x
