X=1 is the answer because you subtract 4x and x, which gives you 3x. Then you subtract 8 and 5, which gives you 3. You should have the equation 3x=3. So divide by 3 and you will get 1, giving you the answer x=1

Answer:

x = 1

Step-by-step explanation:

To solve for a variable, you need to get the variable on one side of the equation, and by itself.

4x + 5 = x + 8

4x = x + 3 --- subtract 5 from both sides

3x = 3 --- subtract x from both sides

x = 1 --- divide both sides by 3

Mini staw<br> D:<br> R:<br> what is the domain and range
IgorC [24]

The entire range of independent variable values is the domain of a function.

After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).

What is domain and range?

  • The collection of all x-values that can cause the function to "work" and produce actual y-values is known as the domain.
  • The range is the set of y-values that are produced when all the conceivable x-values are substituted.

The entire range of independent variable values is the domain of a function.

Keep these things in mind when locating the domain:

  1. A fraction's denominator (bottom) cannot be 0.
  2. In this section, the integer following a square root symbol must be positive.

After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).

The variety of potential y-values makes up a function's range (minimum y-value to maximum y-value)

  1. To observe what happens, substitute several x-values into the expression for y.
  2. Be sure to search for the least and highest y values.

Step-by-step explanation:

2. from the diagram:

sin \theta = \frac{opposite}{hypotenuse}\\sin (8) = \frac{4.5}{AB} \\AB = \frac{4.5}{sin(8)} \\AB = \frac{4.5}{0.1392} \\AB = 32.33ft

Use what you know about decimals or fractions to explain why (0.2)•(0.002)=0.0004
strojnjashka [21]

Answer:

So any time you are multiplying something, you are making "groups of"

so 3 groups of 2 = 6, 4 groups of 3 = 12

But with decimals or fractions, because they are a value less than zero, the numbers become increasingly small instead of bigger, like standard multiplication.

So for example, 1 group of 1/2 = 1/2

2 groups of 1/4 = 1/2

and so on

hope this helps!
