Which equations could you solve using the addition property of equality? Check all that apply.
4+ y = 100
y -4 = 100
4y = 100 4 + 100=y
100 = y - 5

Answers

Answer:

4 + y = 96 = 100

y = 104 - 4 = 100

4 y = 25 = 100 4 + 100 = y = 104

100 = y = 105 - 5

Step-by-step explanation:

Plz mark me as brainliest have a good day

The equations could you solve using the addition property of equality is

y- 4 = 100.

We have to apply the property of addition equality

Now,

4 + y = 100

y= 96

and, y -4 = 100

y = 104

and, 4 y = 100

y= 25

and, 100 = y - 5

y= 105

Thus, the required equality is y- 4 = 100.

What is the inverse of the function shown( in the form of a graph)

Answers

Answer:

[tex] y = - 1x + b[/tex]

Step-by-step explanation:

The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.

[tex] - \frac{1}{m} x[/tex]

m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.

[tex] - \frac{1}{1} x \\ - 1x[/tex]

So the inverse slope would be -1.

Answers

Answer:

Step-by-step explanation:

First, you would do a proportion

[tex]\frac{3}{50}[/tex]=[tex]\frac{x}{300}[/tex]

Then you would cross multiply, getting 50x=900.

After that, you would do 900/50, which is 18.

To paint 300 feet of fence we need 18 quarts of paint.

There was a study done on oxygen consumption of snails as a function of pH, and the result was a degree 4 polynomial whose graph is shown.

Which of the following statements about this function is INCORRECT?

Answers

Answer:

A. There is a positive leading coefficient

Step-by-step explanation:

Polynomials can be represented as an equation or graphs.

The incorrect option is: (b) There is a positive leading coefficient.

The polynomial has a degree of 4; this means that the degree of the polynomial is even.

So option (a) The degree of the polynomial is even is true

From the graph, we can see that the function decreases at (7<x<8) and (9<x<10)

This means that, the function decreases at two intervals

So option (d) There are two intervals where the function is decreasing is also true

Also, the function is at maximum at x = 7 and x = 9.

This means that:

Option (c) At two pH values, there is a relative maximum value

Hence, the incorrect option is:

(b) There is a positive leading coefficient.

This is so because, the graph decreases at some points on the graph.

This means that, the graph has a negative leading coefficient.

Question 25
A stock has a beta of 1.5 and an expected return of 16.35%. What is the risk-free rate if the market rate of return is 12.5%?
96

Answers

Answer:

4.8%

Step-by-step explanation:

Given that :

Stock beta (B) = 1.5

Expected return = 16.35% = 0.1635

Maeket rate of return (Rm) = 12.5% = 0.125

Risk-free rate of return (Rf) =?

Using the relation :

Expected rate of return = risk free rate + Beta(market rate - Risk-free rate)

Expected rate of return = Rf + B(Rm - Rf)

Plugging our values :

0.1635 = Rf + 1.5(0.125 - Rf)

Open the bracket

0.1635 = Rf + 0.1875 - 1.5Rf

Collect like terms

0.1635 - 0.1875 = Rf - 1.5Rf

−0.024 = - 0.5Rf

Divide both sides by - 0.5

0.024 / 0.5 = Rf

Rf = 0.048

Rf = 0.048 * 100% = 4.8%
