Answer: PEMDAS

Step-by-step explanation: You wanna add 1 to both sides and get 3√x = 1. Then you wanna multiply 3 by 3√x which leaves you with x cause it canceled out. But remember to multiply 3 on both sides so x = 1 sq rt 3. Which is just 1.

x = 1

Answer:

$3x+2 \ne x^2 \ne 2x$ for $x = 4$

Step-by-step explanation:

Given

Shape: Triangle

Dimension: 3x + 2, x^2 and 2x

$x = 4$

Required

Determine if it has equal sides

To do this, we simply substitute 4 for x in the given dimensions

3x + 2

$3x + 2 = 3 * 4 + 2$

$3x + 2 = 12 + 2$

$3x + 2 = 14$

x^2

$x^2 = 4^2$

$x^2 = 16$

2x

$2x = 2 * 4$

$2x = 8$

$3x+2 \ne x^2 \ne 2x$ for $x = 4$

Explain why there are only three variables in the expression f(x) = a(b)^x + c as it relates to transformations of an exponentia

UkoKoshka [18]

Answer:

Option A.Exponential decay, 55% decrease

we have

This is a exponential function of the form

where a is the initial value

b is the base

b=(1+r)

r is the rate of change

In this problem

a=54

b=0.45

0.45=1+r

r=0.45-1

r=-0.55

Convert to percentage

r=-55% ------> is negative because is a exponential decay
