Answers

Answer:

Step-by-step explanation:

Part A, the system of equation is, presented here as follows;

(1) 2·y = 3·x + 2

(2) y = 2·x² - 3·x + 2

Part B; The graph of the system of equation is attached

The reason for the above answers is as follows;

Part A

A system of equations are a given number of equations from which a common solution of the system can be found

A linear equation is an algebraic equation in which the maximum exponent of the variables is one and the graph of the equation is a straight line which is of the form y = m·x + c

A maximum value of the exponents of the variable quadratic equation is 2, and the general form of the quadratic equation is y = a·x² + b·x + c, where a, b, and c are real numbers

Therefore, the system of equation that can be created is as follows;

(1) 2·y = 3·x + 2

(2) y = 2·x² - 3·x + 2

Method for solving;

Divide equation (1) by 2, and equate both values of y to find the common solution as follows;

2·y/2 = (3·x + 2)/2 = 1.5·x + 1

∴ y = 1.5·x + 1

Equating both values of y gives;

y = 1.5·x + 1

y = 2·x² - 3·x + 2

Therefore;

1.5·x + 1 = 2·x² - 3·x + 2

2·x² - 3·x - 1.5·x + 2 - 1 = 0

2·x² - 4.5·x + 1 = 0

Using the quadratic formula, we get;

x = (4.5 ± √((-4.5)² - 4×2×1))/(2 × 2)

x = 2, or x = 0.25

From which we get;

y = 1.5 × 2 + 1 = 4, or y = 1.5 × 0.25 + 1 = 1.375

The points where the line graph and the quadratic graph intersect are;

(2, 4), and (0.25, 1.375)

jacob poured 5/6 cup of orange juice and a cup 5/8 of cranberry juice into a pitcher . He drank 1/2 cup of the juice in the pitcher. How many cups of juice are left in the pitcher?​

Answers

We set up the problem first.

5/6 + 5/8 - 1/2.

We would first find a common denominator. It is 24.

Then we see how many times can 24 go into 6, 8, and 2.

We make them into improper or regular fractions, and we subtract regularly.

20/24 + 15/24 - 12/24 = 23/24.

So your answer would be 23/24.

what is the value of 2x to the 3rd power + x to the 2nd power -x when x+3?

Answers

Answer:

I am unsure of the wording of this question, so I will answer both ways I see it.

When x = x + 3, the value of 2x³ + x² - x is 2x³ + 19x² + 59x + 66.

When x = 3, the value of 2x³ + x² - x is 60.

Step-by-step explanation:

x = x + 3 solution:

It is given that:
f(x) = 2x³ + x² - x

We are trying to find this when x = x+3. Substitute this value in for every x in the function.

f(x + 3) = 2(x + 3)³ + (x + 3)² - (x + 3)

Expand the first part.

f(x + 3) = 2(x + 3)(x + 3)(x + 3) + (x + 3)² - (x + 3)

Multiply pairs together.

f(x + 3) = 2(x + 3)(x² + 6x + 9) + (x + 3)² - (x + 3)

Multiply the remaining pairs together.

f(x + 3) = 2(x³ + 9x² + 27x + 27) + (x + 3)² - (x + 3)

Distribute the two inside the parenthesis.

f(x + 3) = 2x³ + 18x² + 54x + 54 + (x + 3)² - (x + 3)

Evaluate (x + 3)².

f(x + 3) = 2x³ + 18x² + 54x + 54 + (x² + 6x + 9) - (x + 3)

Remove all parenthesis and start simplifying.

f(x + 3) = 2x³ + 18x² + 54x + 54 + x² + 6x + 9 - x - 3

Combine all terms ending in x².

f(x + 3) = 2x³ + (18x² + x²) + 54x + 54 + 6x + 9 - x - 3

f(x + 3) = 2x³ + 19x² + 54x + 54 + 6x + 9 - x - 3

Combine all terms ending in x.

f(x + 3) = 2x³ + 19x² + (54x + 6x - x) + 54 + 9 - 3

f(x + 3) = 2x³ + 19x² + 59x + 54 + 9 - 3

Last, combine the final numbers to get:

f(x + 3) = 2x³ + 19x² + 59x + 60

x = 3 solution:

It is given that:
f(x) = 2x³ + x² - x

Substitute 3 in for every value of the function.

f(3) = 2(3)³ + (3)² - 3

Evaluate 3 cubed and then multiply it by 2.

f(3) = 2(27) + 3² - 3

f(3) = 54 + 3² - 3

Evalute 3 squared.

f(3) = 54 + 9 - 3

Add 54 and 9.

f(3) = 63 - 3

Subtract 3 from 63 to get:

f(3) = 60

Omar claims that because 50% of the frozen treats sold in Week 1 were sundae cups, the sundae cups accounted for 50 % of the profit.

Total number of the frozen treats = 100%

Step-by-step explanation:

4x + 1 = 5(x-3y) - 6

3(x+6y) + 4 = 9y + 19

Simplify both equations

4x + 1 = 5x-15y - 6

-x + 15y = -7

3x + 18y + 4 = 9y + 19

3x + 9y = 15

Now multiply 3 on both sides for the first equation.

(easier for adding both equations)

-3x + 45y = -21

3x + 9y = 15

Add both equations

x cancels out

54 y = -6

y = -1/9

plug in to other equation

3x + 9y = 15

3x - 1 = 15

Answers

The z-statistic for Brett's data is found to be as given by: Option A: -5.30 (approx).

How to find the value of z-statistic for population mean?

Suppose we're specified that:

The sample mean = [tex]\overline{x}[/tex]The population mean = [tex]\mu[/tex]The population standard deviation = [tex]\sigma[/tex]The sample size = n

Then the z-statistic for this data is found as:

For this case, we've got:

The sample mean = [tex]\overline{x}[/tex] = 295The population mean = [tex]\mu[/tex] = 310The population standard deviation = [tex]\sigma[/tex] = 20The sample size = n = 50

Thus, we get:

For an art project, a cone is covered with paper without any gaps or overlaps. The height of the cone is 28 inches and its diameter is 14 inches.


What is the surface area of the covering to the nearest square inch?

Answers

The surface area of the covering of the cone to the nearest square inches is 788 inches²

Surface area of a cone

surface area of a cone = πr(r + l)

where

r = radiusl = slant length

Therefore,

diameter = 2(radius)

14 = 2r

r = 14 / 2

r = 7 inches

l² = 7² + 28²

l = √49 + 784

l = √833

l = 28.8617393793

l = 28.86 inches

Therefore,

surface area = 3.14 × 7 (7 + 28.86)

surface area = 21.98 × 35.86
