what is the equation of the line?

Answers

Answer:

x=3

Step-by-step explanation:

try different values on the line! plug them in and you'll see that every x value is 3!

Answer:

x=3

Step-by-step explanation:

Because there is no slope (or the slope is undefined), there is another way to write the equation. Instead of y=mx+b, it will be either x=b or y=b, y=b being a horizontal line and x=b being vertical. To find b, simply find the value of x or y. The line has infinite points on it with one similarity, being their x value is 3. Hence, the equation is x=3.

Answers

Your answer would be x = -1.

We can find this by first expanding the brackets on both sides of the equation:

4x + 8 = 6x + 10

Now we can rearrange and solve for x:

4x + 8 = 6x + 10

- 4x

8 = 2x + 10

- 10

-2 = 2x

÷ 2

-1 = x

I hope this helps!

Answer:

x = - 1

Step-by-step explanation:

Given

4(x + 2) = 2(3x + 5) ← distribute parenthesis on both sides

4x + 8 = 6x + 10 ( subtract 6x from both sides )

- 2x + 8 = 10 ( subtract 8 from both sides )

- 2x = 2 ( divide both sides by - 2 )

x = - 1

A) 5
B) 9
C) 12
D) 15

Answers

Answer:

We found the factors and prime factorization of 27 and 45. The biggest common factor number is the GCF number. So the greatest common factor 27 and 45 is 9.

Step-by-step explanation:

9 is the common factor of both 27 and 45 cause 9 * 5 is 45 and 9*3 is 27

There are many variables that affect the calculation of a patient’s total blood volume. For the purposes of this question, weight and age will be the only variables considered. The Australian Red Cross states that “Blood volume can be estimated as approximately 70mL/kg for adults, 80mL/kg in children…”. Work on the assumption that an adult is a person aged 16 years or over and a child is a person aged 2 to 16 years.

Let:
W = Weight (kg)
P = Plasma volume (mL) and
T = Total blood volume (mL)

Write 2 equations for calculating Total blood volume (T) given Weight (W), expressing T in terms of W, one for adults and one for children:

Answers

Answer:

The two equations are;

For adults, T = W kg × 70 mL/kg ............Equation (1)

For children, T = W kg × 80 mL/kg.............Equation (2)

Step-by-step explanation:

We are told that

Blood volume = 70 mL/kg for adults

Blood volume = 80 mL/kg in children

Therefore, the total blood volume,T of an adult of weight, W is given by the following relation;

T = W kg × 70 mL/kg ............Equation (1)

The total blood volume,T of a child of weight, W is given by the following relation;

T = W kg × 80 mL/kg.............Equation (2).

The student council at Richmond High School
is made up of 646 female students 229
seniors, and 6% female seniors.
If a student is selected at random, what is the
probability, as a decimal to the nearest
hundredth, that the student is female given that
the student is a senior?

Answers

Answer:

[tex]P(F/S)=0.216[/tex]

Step-by-step explanation:

Let's call F the event that the student is female and S the event that the student is senior.

So, we need to find the probability P(F/S) that a student is female given that the student is a senior. P(F/S) is calculated as:

P(F/S) = P(F∩S)/P(S)

Then, the probability P(F∩S) that a student is female and senior is equal to 0.06

On the other hand, we can calculate the total number of students x using the following equation as:

[tex]\frac{646}{x}+\frac{229}{x}-0.06=1[/tex]

Where 646/x is the percentage of female students, 229/x is the percentage of senior students and 0.06 is the percentage of female seniors.

Then, solving for x we get that the number of students is 825.4719

Additionally, the probability P(S) that a student is a senior is equal to:

[tex]P=\frac{229}{825.47} =0.2774[/tex]

Because there are 825.47 students and 229 are senior.

So, P(F/S) is equal to:

[tex]P(F/S)=\frac{0.06}{0.2774}=0.216[/tex]
