Solve the equation using the zero-product property 4X(X + 4) = 0​

Answer:

The answer to this is m equals 16.

Answer:

m= 2

Step-by-step explanation:

1+2m^-1/2=3/2

So, subtract 1

2m^-1/2 = 1/2

Divide by 2.

m^-1/2 = 1/4

m=2.

Step-by-step explanation:

Factoring a Trinomial

A trinomial is expressed in the form

[tex]ax^2+bx+c[/tex]

Where a,b, and c are real constants.

Some trinomials can be factored as the product of binomials with real coefficients, while others cannot.

If possible, factoring can be done in several ways:

Each method is most likely applicable under certain circumstances. When the polynomial has a leading coefficient of a=1, the sum-product pattern is the fastest and easiest option.

We have the polynomial

[tex]x^2-x-12[/tex]

Here: a=1, b=-1, c=-12

The sum-product method needs us to find two numbers which sum is -1 and product is -12. Those numbers can be found by inspection by combining two divisors of 12, say 1 and 12, 2 and 6, or 3 and 4.

Only one of those pairs can be combined to produce a sum or subtraction equal to -1: Those numbers are -4 and 3. Thus the factorization is:

[tex]\mathbf{x^2-x-12=(x-4)(x+3)}[/tex]

Answer:

No values of x- Any whole number that is not 8

All values of x: 8

Just one Value of x: There could be many possibilites but all of them have to be some value of x. One answer is:x

Step-by-step explanation:

3x + 8 = 3x + x, which has one solution at x=8.

The given equation is 3x+8=3x+ ____.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

If 3x + 8 = 3x + 7 has no solutions

If 3x + 8 = 3x + 8 has infinite solutions

If 3x + 8 = 3x + x is equal to 3x + 8 = 4x, which has one solution at x=8

Therefore, 3x + 8 = 3x + x, which has one solution at x=8.

Answer:

Expression: [tex] \frac{40}{y - 16} [/tex]

When y = 20, the value of the expression is 10.

Step-by-step explanation:

The expression for the phrase "difference of a number, y, and 16" is (y - 16).

Therefore, the quotient of 40 and the "difference of a number, y, and 16" would be written as:

[tex] \frac{40}{y - 16} [/tex]

Let's evaluate the expression when y = 20.

Substitute y = 20 into [tex] \frac{40}{y - 16} [/tex].

Thus:

[tex] \frac{40}{20 - 16} [/tex]

[tex] = \frac{40}{4} = 10 [/tex]

Answer:

8.08 %

Step-by-step explanation:

Let us denote : [tex]X=[/tex] score X follows a normal distribution with mean [tex]=24[/tex] and standard deviation [tex]=1.5[/tex]

Step 2

The probability that someone scored 21.9 or less is :

[tex]\mathrm{P}(\mathrm{X} \leq 21.9)[/tex]

[tex]=\mathrm{P}\left(\mathrm{Z} \leq \frac{21.9-24}{1.5}\right)[/tex]

[tex]=\mathrm{P}(\mathrm{Z} \leq-1.4)[/tex]

[tex]=0.0808[/tex]

[tex]=8.08%[/tex]

Answer : [tex]8.08 %[/tex]

======================================================

Work Shown:

A = event of losing $100

P(A) = probability event A occurs = 0.20

V(A) = net gain of event A happening = -100

B = event of gaining $30

P(B) = probability event B occurs =  0.80

V(B) = net gain of event B happening = 30

-----------------

E(X) = expected value

E(X) = P(A)*V(A) + P(B)*V(B)

E(X) = 0.20*(-100) + 0.80*(30)

E(X) = 4

The expected value is $4

This means the investor expects to get an average return of $4.

We have a question to answer

given that the speed is 6 mph and the time taken is 3 hours

v= 6mph, t= 3, distance =?

distance= speed * time

distance= 6*3= 18miles

From the distance calculated, we can see that there exist a proportional relationship, lets say the time taken is 4 hours, then the distance will be

distance= 6*4= 24 miles.

hence the distance traveled is proportional to the time taken
