What is the value of the expression if z=27?
7/9z-18+1/3z
A. 12
B. 30
C. 48
D. 84

Answer:

[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Step-by-step explanation:

Given

P = Test is positive

D = Disease is present

Required

Write an expression when disease is present but test says that the disease is not present

The above statement can be split to two

Disease is Present          &        Test is not positive

The first statement:

Disease is Present  means D

The second statement

Test is not positive means not P

Mathematically;

not P means P' or [tex]P^c[/tex]

So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Answer:

What is the inverse of the function f(x) = 1/4x - 12? h(x) = 4x + 48. Which statement is true regarding the functions on the graph? f(3) = g(3)

Step-by-step explanation:

Answer:

To have an infinite number of solutions, the equations must graph the same line. That means the equations must be equivalent. To form an equivalent equation, use the properties of equality to rewrite the given equation in a different form. Add, subtract, multiply, or divide both sides of the equation by the same amount.

Step-by-step explanation:

it's the sample answer

For the system of linear equations that has an infinite number of solutions, then both equations must have the same slope and the same y-intercept.

The equation is given as:

[tex]\mathbf{y = \frac 23x - 5}[/tex]

To create a system of linear equations that has an infinite number of solutions, then both equations must be the same.

Examples of such equations are:

[tex]\mathbf{y + 5= \frac 23x }[/tex]

[tex]\mathbf{3y= 2x -15}[/tex]

Hence, for the system of linear equations that has an infinite number of solutions, then both equations must have the same slope and the same y-intercept.

Answer:

y - 6x = 18

Step-by-step explanation:

Answer:

Let y=34 and x=3

Step-by-step explanation:

y = 8x + 10

34 = 8 (3) + 10

34 = 24 + 10

34 = 34

Hence,3 and 34 satisfies this equation.

Answer:

the cost is now $5.40

Step-by-step explanation:

if 18.00 is 100%, and we need to find the new price we need to make 30% into a decimal. which is 0.3. then we multiply 0.3 times 18.00, and that equals 5.4, but since we are dealing with money the answer would be $5.40.

we multiply if we are trying to find the new amount and we divide to find the old amount.

Answer:

y =  [tex]-\frac{1}{6}[/tex] x - 2

Step-by-step explanation:

Given coordinate:

          ( − 6 , − 1 )

Equation of the given line is  6x− y = 7

Unknown:

Equation of the line that passes through the point and is perpendicular = ?

Solution:

A perpendicular line will have a slope that is of negative inverse to the one given;

              6x  - y  = 7

                     -y  = -6x  + 7

                     y  = 6x - 7

According to y= mx + c

 y and x are the coordinates

    m is the slope

     c is the y-intercept

Therefore, the slope of the line  = 6

  Perpendicular to this = [tex]-\frac{1}{6}[/tex]

 The new line will be;

       Let find the intercept;

             -1  =  [tex]-\frac{1}{6}[/tex] x (-6) + c

             -1  = 1 + c

               c = -2

The new line is;

              y =  [tex]-\frac{1}{6}[/tex] x - 2

Answer:

Answer:

−(d+1)>3

Step 1: Simplify both sides of the inequality.

−d−1>3

Step 2: Add 1 to both sides.

−d−1+1>3+1

−d>4

Step 3: Divide both sides by -1.

[tex]\frac{-d}{-1}[/tex] >  [tex]\frac{4}{-1}[/tex]

Answer: Check explanation

Step-by-step explanation: (3,-5), because that's the point where the two lines intersect.

Y=-2x+1

Y=-3/2x-1/2

Substitute the Y to get -2x+1=-3/2x-1/2

1/2x=3/2

x = 3

Now plug x into first equation: y=-2*3+1=-5

so the intersection point is (3,-5)
