Rearrange the formula for y2

Rearrange The Formula For Y2

Answers

Answer 1

Answer:

y2 = m(x1 - x2)+ y1

Step-by-step explanation:

m = y2 - y1 / x1 - x2

m(x1 -x2) = y2 -y1

y2 = m(x1 - x2)+ y1

Answer 2

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1)

Multiply both sides by (x2 - x1)

m(x2 - x1) = y2 - y1

Add y1 to both sides

m(x2 - x1) + y1 = y2

y = m(x2 - x1) + y1

If P(x) = x ^ 2 + x + 3 and Q(x) = 4x ^ 2 - 3 find P(8) .

Answers

Answer:

75

Step-by-step explanation:

Giving Q was not necessary because you aren't doing P(Q) or anything like that....

Anyways,

[tex]p(x) = x^2 + x +3\\[/tex]

Since you're doing p(8), you would replace the x's with 8s.

[tex](8)^2 + (8) + 3 = 64 + 8 + 3 =75[/tex]

So your final answer would be 75.

The cube root of 512 is 8, the value of  ∛512 is 8.

What is Number system?

A number system is defined as a system of writing to express numbers.

The given expression is ∛512

To evaluate the cube root of 512, we can factor 512 as follows:

512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

We can then group the factors into sets of three, as follows:

512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2) = 8 × 8 × 8

Therefore, we have:

∛512 = ∛(8 × 8 × 8)

= 8

Hence, the cube root of 512 is 8.

Explain what classifies a number as rational (your answer should specify what makes it rational as opposed to irrational).

Answers

Rational numbers are numbers that can be absolutely determined. This includes integers, limited decimals, repeating decimals, and fractions. Examples include 1, 1.25, 1.38383838..., and 1/2. Irrational numbers are numbers that cannot have their absolute value determined. This excludes every example for rational numbers. An example of an irrational number is 3.1415926535879...

Answer:

y = 3x + 5

Step-by-step explanation:

The equation in slope- intercept form is

y = mx + c

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (2, 11) ← 2 ordered pairs from the table

m = [tex]\frac{11+1}{2+2}[/tex] = [tex]\frac{12}{4}[/tex] = 3, thus

y = 3x + c ← is the partial equation

To find c substitute any ordered pair from the table into the partial equation

Using (2, 11 ), then

11 = 6 + c ⇒ c = 11 - 6 = 5

y = 3x + 5 ← equation of linear function

I played 4 video games and had an average score of 12,000 points
per game. The average score of the first 3 games was 11,000 points
per game. How many points did I score in the 4th game?

Answers

Answer:

  15,000

Step-by-step explanation:

The first three games leave you with at total that is 3000 below the average. So, the last game has a score that is 3000 above average:

  12000 +3000 = 15000 points scored in 4th game

__

Check

(11000 +11000 +11000 +15000)/4 = 48000/4 = 12000

The average of anything is calculated by adding up all the values and dividing by the number of values.

The Average = 12,000

the # of values = 4

x = score of the 4th game

(11,000 + 11,000 + 11,000 + x) / 4 = 12,000

First, let's multiply both sides by 4

11,000 + 11,000 + 11,000 + x = 48,000

Let's simplify the left side

33,000 + x = 48,000

Subtract 33,000 from both sides

x = 15,000

You scored 15,000 points in the 4th game

Answers

Answer:

Step-by-step explanation:

No solution - 2y – 3 = 5 + 2(y – 1), one solution - (1/5)f – 2/3 = – (1/5)f + 2/3, 4a – 3 + 2a = 7a – 2, infinitely many solution - [-3(n + 4) + n = -2(n + 6)], -1.7v + 2.8 = 1.4v – 3.1v + 2.8.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

If the exponent of the variable is one, then one solution.

If both sides are zero, then no solution.

And if the variable is eliminated, then the infinitely many solutions.

-1.7v + 2.8 = 1.4v – 3.1v + 2.8, it has infinitely many solutions.

4a – 3 + 2a = 7a – 2

a = -1, it has one solution.

(1/5)f – 2/3 = – (1/5)f + 2/3

f = 5/3, it has one solution.

2y – 3 = 5 + 2(y – 1)

0 = 0, it has no solution.

-3(n + 4) + n = -2(n + 6), it has infinitely many solutions.

given that,

My son drinks 3 cups of milk a day. There are 8 ounces in a cup.

so, we have,

My son drinks milk:

3 Cups/Day

we know, 8 ounces = 1 cup

so, we get,

3*8=24 ounces/Day

now, we have,

7 day = 1 week

we get,

24*7=168 ounces/Week

we have,

168*10=1680 ounces in 10 Weeks.

Hence, The solution is : 1680 ounces  he will drink after 10 weeks.

Joe is 14 years older than his cousin Tom.
Cousin Rob is 3 times as old as Tom. The sum of all
three of their ages is 64. Find each of their ages.

Answers

x = Tom's age

x + 14= Joe's age

3x = Rob's age

x + (x + 14) + 3x = 64

Let's combine like terms

5x + 14 = 64

Subtract 14 from both sides

5x = 50

Divide each side by 5

x = 10

Tom is 10 years old.

Joe's age = 10 + 14 = 24 years old

Rob's age = 3(10) = 30 years old
