Answer 1

Answer:

L: y= -4x + 17

Step-by-step explanation:

For a line L to pass through two points, we use the slope formula to calculate the slope, m, where

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

= (9-1) / (2-4)

= 8 / -2

= -4

Next we use the point slope form to find the line equation:

L: (y-y1) = m (x-x1)

substitute (x1,y1) = (4,1)

L: y-1 = -4 (x-4)

Simplify:

L: y = -4x + 16 + 1

L: y= -4x + 17

Check: substitute (4,1)

y = -4(4)+17 = 1 checks

substitute (2,9)

y = -4(2)+17 = 9 checks

L: y= -4x + 17

What is the solution set for this system of equations?

4x + y = 13
x − 3y = 0

Answers

Answer:

(3, 1)

Step-by-step explanation:

Pre-Solving

We are given the following system:
4x + y = 13

x - 3y = 0

We want to find the solution.

We can solve this system with substitution, where we solve one of the variables for the other, then substitute that value into the other equation.

Solving

To start, we can add 3y to both sides to solve for x.

x - 3y = 0

+3y +3y

____________________

x = 3y

Now, substitute x as 3y in 4x + y = 13

4(3y) + y = 13

12y + y = 13

13y = 13

y = 1

Now, substitute 1 as y in x=3y

x = 3(1)

x = 3

Our solution is x = 3, y = 1. As a point, that is (3,1).

The solution set for this system of equations is (3,1)

A toy company's total payment for salaries for the first two months of 2012 is $40,765. Write and solve an equation to find the salaries for the second month if the first month’s salaries are $10,205.

Answers

Answer:

its D

12,455 + x = 23,894

x = 10,560

Step-by-step explanation:

Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:

10,205 + x = 23,894

To solve, we must isolate the variable by subtracting 12,455 from both sides:

10,205 + x = 23,894

-10,205 -10,205

x = 10,560

So, the second month's salary was $10,560

Step-by-step explanation:

Answer: x = $30,560

Step-by-step explanation:

1. Let the second month payment be x

2. The first month + The second month = both of the months

3. So substituting: 10,205 + x = 40,765

4. Subtract 10,205 from both sides: x = 30,560

A pitcher contains 14.25 cups of iced tea. You drink 2.5 cups of the tea each morning and 2.25 cups of the tea each evening. When will you run out of iced tea?

Answers

Answer:

You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)

Step-by-step explanation:

Day 1 - 9.5 cups left

14.25 - 2.5 - 2.25 = 9.5

Day 2 - 4.75 cups left

9.5 - 2.5 - 2.25 = 4.75

Day 3 - 0 cup left

4.75 - 2.5 - 2.25 = 0

Answer: You will run out of iced tea in 3 days

Step-by-step explanation:

2.5 + 2.25 = 4.75

14.25/4.75 = 3

What is the correct expanded form and value of (One-fifth) Superscript 4?
One-fifth + one-fifth + one-fifth + one-fifth = StartFraction 4 Over 5 EndFraction
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
StartFraction 1 + 1 + 1 + 1 Over 5 times 4 EndFraction = StartFraction 4 Over 20 EndFraction
One-fifth times 4 = StartFraction 4 Over 5 EndFraction

Answers

Answer:

One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction

Step-by-step explanation:

1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625

The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."

The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.

In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."

Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.

Mathematical representation: $\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}$
