Solve The System Of Linear Equations By Graphing Y = -4x + 2 ; Y = -x - 1 What Is The Solution?

Answers

Answer 1

Answer:

Step-by-step explanation:

Easiest way would be to substitute points into the given equations and plot your answers.

E.g. if you substitute points into your first equation you get:

If x = 0, y = -4(0) +2 = 2

If x = 1, y = -4(1) +2 = -2

If x = -1, y = -4(-1) +2 = 6

Etc.

Second equation:

If x = 0, y= -(0) -1 = -1

If x = 1, y = -1 -1 = -2

If x = -1, y = -(-1) -1 = 0

Pretty much just plug in values for x into the equations to find y.

Once you have your points, draw a line :)

Where the two lines intercept would be the solution.

Line M passes through points (4, 2) and (-7, 1) what is the slope of a line N that is parallel to line M

Answers

1/11 use rise Over run

The solution is :

We conclude that the slope of line 'n' is: m₂ = 10

What is slope?

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Given

The slope of line m is: m₁ = 10

It is stated that another line is parallel to line m.

Let m₂ be the slope of the 'n' line.

We know that when two lines are parallel, they have equal slopes.

i.e.  m₁ = m₂

as

The slope of line m is: m₁ = 10

and

The lines are parallel

so

The slope of line 'n' is: m₂ = 10

Therefore, we conclude that the slope of line 'n' is: m₂ = 10.

Jenny has only 3 1/2 cups of flour in her house. She needs 1 5/8 cups for a brownie recipe. Her sister Jody needs 1 3/4 cup flour for her cookie recipe. Will there be enough flour for both recipes?

Answers

Answer:

yes, Jenny has enough flour for both recipes

Step-by-step explanation:

First, find what Jody and Jenny need for both their recipes. For this, we need a common denominator, 8

1 5/8=13/8

3/4=6/8

13/8+6/8=19/8

Jody has 3 1/2 cups of flour, which is 7/2 cups or 28/8.

Now we need to make sure that 28/8 is greater than 19/8

28>9.... so she has enough flour!

The probability that the client owns a cat is 16/35 if a veterinarian records whether the client owns a cat, a dog, neither, or both option (A) is correct.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

The veterinarian records whether the client owns a cat, a dog, neither, or both.

What is the average daily balance?

The average daily balance can be determined by dividing the total daily balaces for August by the number of days in August.

The average daily balance = total balance / total number of days in Augst.

Total balance = (1500 x 3 days) + (1100 x10 days) + (850 x 10 days) + (750 x 7 days)

Total balance = 4500 + 11,000 + 8,500 + 5,250 = 29,250

The required answer is,

A) The weight of 4 fruits round to the nearest 0.1 pound is-

Apple = 2.1

Blueberries = 1.1

lemon = 1.0

Orange = 3.5

B) The weight of 4 vegetables round to the nearest 0.01 pound is-

Asparagus = 2.32

Beats = 1.86

Celery = 1.40

Corn = 2.56

What is rounding of digit?

Rounding is a process to estimate a particular number in a context.

To round a number look at the next digit in the right place, if the digit is less than 5, round down and if the digit is 5 or more than 5, roundup.

Now the given weights in pounds of the fruits are,

Apple = 2.068

Blueberries = 1.07

lemons = 1.031

Orange = 3.502

Peaches = 2.608

Pears = 3.592

The given weights in pounds of the vegetables are,

Asparagus = 2.317

Beats = 1.862

Celery = 1.402

Corn = 2.556

Potatoes = 3.441

Red onions = 1.863

Now picking the 4 fruits,

Apple = 2.068

Blueberries = 1.07

lemons = 1.031

Orange = 3.502

To round the weight to the nearest 0.1 pounds we see the digit at 0.1 place, if the digit right to the 0.1 place is greater than or equal to 5 roundup the digit, and if it is less than 5 round down the digit.

Thus,here we get

2.068 = 2.1

1.07 = 1.1

1.031 = 1.0

3.502 = 3.5

Thus, the weight of 4 fruits round to the nearest 0.1 pound is-

Apple = 2.1

Blueberries = 1.1

lemon = 1.0

Orange = 3.5

Now picking 4 vegetables,

Asparagus = 2.317

Beats = 1.862

Celery = 1.402

Corn = 2.556

To round the weight to the nearest 0.01 pounds we see the digit at 0.01 place, if the digit right to the 0.01 place is greater than or equal to 5 roundup the digit, and if it is less than 5 round down the digit.

Thus,here we get

2.317 = 2.32

1.862 = 1.86

1.402 = 1.40

2.556 = 2.56

Thus, the weight of 4 vegetables round to the nearest 0.01 pound is-

Asparagus = 2.32

Beats = 1.86

Celery = 1.40

Corn = 2.56

The required answer is,

A) The weight of 4 fruits round to the nearest 0.1 pound is-

Apple = 2.1

Blueberries = 1.1

lemon = 1.0

Orange = 3.5

What is the value of 4x – 3y if x = 3 and y = 6?

Answers

Answer:

-6

Step-by-step explanation:

If x=3 and y=6, 4x-3y=-6 because 4x with x=3 makes the first number 12. 3y with y=6 makes the result 18, so now the equation is 12-18. 12-18=-6, so 4x-3y with x=3 and y=6 will equal -6.

Hopefully the answer and explanation helps!

Answer:

-6

Step-by-step explanation:

All you have to do is plug in the numbers. So it should look like 4(3) - 3(6). Now all you have to do is solve. 4 x 3 = 12. 3 x 6 = 18. Now subtract. 12 - 18 = -6

According to one source, the average cumulated college student loan debt for a graduating senior is $29,400. Assume that such debt is normally distributed and that the standard deviation is $5,684. Thirty percent of these graduating seniors owe more than what amount?

Answers

Answer:

$32378.416

Step-by-step explanation:

We are asked to find: Thirty percent of these graduating seniors owe more than what amount.

More than 30% = Finding the z score of the 70% percentile.

The z score = 0.524

Hence, using z score formula:

z = (x-μ)/σ

0.524 = x - $29,400/$5,684

0.524 × 5684 = x - 29400

2978.416 = x - 29400

x = 29400 + 2978.416

x = $32378.416

Therefore, Thirty percent of these graduating seniors owe more than what amount $32378.416.

The surface area of a right square pyramid is given by A=b2+2bh where b is the length of a side of the base and h is the slant height.solve the formula for h if b=3

Answers

Answer:

Step-by-step explanation:

A = 9 + 6h

6h = A - 9
