Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

0.74y = 128

<u>Step 2: Solve for </u><em><u>y</u></em>

  1. Divide both sides by 0.74:                    y = 172.973

<u>Step 3: Check</u>

<em>Plug in y into the original equation to verify it is a solution.</em>

  1. Substitute in <em>y</em>:                   0.74(172.973) = 128
  2. Multiply:                              128 = 128

Here we see that 128 does indeed equal 128.

∴ y = 172.973 is a solution of the equation.

Y = 172.972972972...

You need to isolate the variable, y. To do this, you need to divide both sides of the equation by 0.74. This gives you your final answer.

The graph of an absolute value function contains the points (–3, 5), (0, 2) and (3, 5). Which could be the function represented
Alex73 [517]

The absolute value functions that contains the points are:

  • f(x) = |x| + 2
  • f(x) = |-x| + 2

<h3>Which could be the function represented by this graph?</h3>

Here we have the points (-3, 5), (0, 2), and (3, 5). We want to see which ones of the given functions have that points.

To check that, we need to evaluate the functions in the first value of each point and see if the outcome is the second value of the correspondent point.

For example, for the first equation:

  • f(-3) = |-3| + 2 = 5   so it has the point (-3, 5)
  • f(0) = |0| + 2 = 2  so it has the point (0, 2)
  • f(3) = |3| + 2 = 5  so it has the point (3, 5).

The other option that also contains these 3 points is:

f(x) = |-x| + 2

  • f(-3) = |3| + 2 = 5  so it has the point (-3, 5)
  • f(0) = |-0| + 2 = 2  so it has the point (0, 2)
  • f(3) =  |-3| + 2 = 5  so it has the point (3, 5).

And all the other options can be trivially discarded (by evaluating them).

So the two correct options are:

  • f(x) = |x| + 2
  • f(x) = |-x| + 2

5 x (10^2) is equal to: 450 4,500 45,000 450,000
vazorg [7]
5 x (10^2) =
5 x 100 = 500

I guess you mean:
4,5 x (10^2) =
4,5 x 100 =
450

Which acctually is a valid answer.

Suppose the manager of a gas station monitors how many bags of ice he sells daily along with recording the highest temperature e
Maslowich

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Equation of regression line :

Yˆ = −114.05+2.17X

X = Temperature in degrees Fahrenheit (°F)

Y = Number of bags of ice sold

On one of the observed days, the temperature was 82 °F and 66 bags of ice were sold.

X = 82°F ; Y = 66 bags of ice sold

1. Determine the number of bags of ice predicted to be sold by the LSR line, Yˆ, when the temperature is 82 °F.

X = 82°F

Yˆ = −114.05+2.17(82)

Y = - 114.05 + 177.94

Y = 63.89

Y = 64 bags

2. Compute the residual at this temperature.

Residual = Actual value - predicted value

Residual = 66 - 64 = 2 bags of ice

Find the domain of fg
vazorg [7]
We have the following functions:
 f (x) = x ^ 2 + 1
 g (x) = 1 / x
 Multiplying we have:
 (f * g) (x) = (x ^ 2 + 1) * (1 / x)
 Rewriting:
 (f * g) (x) = ((x ^ 2 + 1) / x)
 Therefore, the domain of the function is given by all the values of x that do not make zero the denominator.
 We have then:
 All reals except number 0
 Answer:
 
b. all real numbers, except 0
