What is the inverse of the function? g(x)=-4/3x+2

Answer:

Subtracting

Step-by-step explanation:

We know that the slope of a line is given by the rise over run. where rise is vertical difference between two points and run is the horizontal distance between the points.

[tex]\text{if }(x_1,y_1) \text{ and }(x_2,y_2)\text{ are two points on a line, then the}\\\text{slope of the line is given by}\\\\\text{Slope, }m=\frac{y_2-y_1}{x_2-x_1}\\\\\text{since slope}=\frac{\text{Rise}}{\text{Run}}, \text{ so Rise}=y_2-y_1\\\\\text{so we can find the rise by subtracting the Y-coordinate of the left point }\\\text{from the y-coordinate of the right point}.[/tex]

Answer:

3.82 pounds.

Step-by-step explanation:

We have been given that at the grocery store, Vanessa bought 1.02 pounds of ground beef, 1.6 pounds of tomatoes, and 1.2 pounds of chicken.

To find the total weight of three items, let us add 1.02, 1.6 and 1.2.

[tex]\text{The total weight of three items}=1.02+1.6+1.2[/tex]

[tex]\text{The total weight of three items}=3.82[/tex]

Therefore, three items weigh 3.82 pounds altogether.

Final answer:

Vanessa bought a total of 2.82 pounds of food, calculated by adding the weight of the ground beef, tomatoes, and chicken she purchased.

Explanation:

To calculate the total weight of the ground beef, tomatoes, and chicken Vanessa bought, simply add up their weights:

Ground beef: 1.02 pounds

Tomatoes: 1.6 pounds

Chicken: 1.2 pounds

To find the sum, you can add these values together:

1.02 + 1.6 + 1.2 = 2.82 pounds

So, Vanessa bought a total of 2.82 pounds of food.

Answer:

The density of the  bar of gold is  19.32 grams per cubic centimeter .

Step-by-step explanation:

Formula

[tex]Density = \frac{Mass}{Volume}[/tex]

As given

A bar of gold has a volume of 722 cubic centimeters and weighs 13.949 kilograms.

As 1 kilogram = 1000 gram

Than convert 13.949 kilograms into grams.

13.949 kilograms = 13.949 × 1000 grams

                             = 13949 grams

Mass = 13949 grams

Volume = 722 cubic centimeter

As put in the formula

[tex]Density = \frac{13949}{722}[/tex]

Density = 19.32 grams per cubic centimeter (Approx)

Therefore the density of the  bar of gold is  19.32 grams per cubic centimeter .

Answer:

One number is [tex]\frac{5}{7}[/tex] and the other number is [tex]\frac{1}{7}[/tex]

Step-by-step explanation:

Let x be the smaller number and y be the bigger number.

x = x

y = 5x

6x + 3y = 3

6x + (3 * 5x) = 3

6x + 15x = 3

(÷3)

2x + 5x = 1

7x = 1

x = [tex]\frac{1}{7}[/tex]

6x + 3y = 3

6([tex]\frac{1}{7}[/tex]) + 3y = 3

[tex]\frac{6}{7}[/tex] + 3y = 3

3y = 3 - [tex]\frac{6}{7}[/tex]

3y = [tex]\frac{15}{7}[/tex]

Divide both sides by 3 to get 1y:

y = [tex]\frac{5}{7}[/tex]

So one number is [tex]\frac{5}{7}[/tex] and the other number is [tex]\frac{1}{7}[/tex]

Answer:Han's mixture tastes stronger

Step-by-step explanation: Han's mixture tastes stronger, because...

Han's uses 6 2/3 cups of water for every 1 cup of orange juice concentrate.

Clare uses 71/2 cups of water for every 1 cup of orange juice concentrate.

Answer:

Han's juice has 15% concentration which is larger and hence, his juice will be stronger.

Step-by-step explanation:

It is required to find that which juice is stronger. So, we need to find the juice with maximum fraction or percentage of juice out of both the cases.

In first case, Clare mixes [tex]2\dfrac{1}{2}=\dfrac{5}{2}[/tex] cups of water with [tex]\dfrac {1}{3}[/tex] cup of orange juice. So, the concentration of the juice will be,

[tex]\dfrac{1/3}{5/2}=\dfrac{2}{15}=13.33\%[/tex]

In the second case, Han mixes [tex]1\dfrac{2}{3}[/tex]  cups of water with [tex]\dfrac{1}{4}[/tex] cup of orange juice.

So, the concentration of the juice will be,

[tex]\dfrac{1/4}{5/3}=\dfrac{3}{20}=15\%[/tex]

Therefore, out of the two cases, Han's juice has 15% concentration which is larger and hence, his juice will be stronger.

Answer:

The answer is 25

Step-by-step explanation:

Therefore, there are 25 red flowers in Sakura’s garden1.

We know that for every 55 red flowers, there are 1010 yellow flowers.

The total number of flowers in the garden is 7575 (which includes both red and yellow flowers).

Let’s use the variable (x) to represent the number of red flowers in the garden. We can set up the following ratio:

[tex][ \frac{{\text{{Red flowers}}}}{{\text{{Total flowers}}}} = \frac{{55}}{{55 + 1010}} ][/tex]

Solving for (x):

[tex][ \frac{{\text{{Red flowers}}}}{{7575}} = \frac{{55}}{{55 + 1010}} ][/tex]

Cross-multiplying:

The given system of equations are solved to obtain x = -2 and y = 3.

The given system of equation can either have a unique solution, more than one solutions or no solution.

On this basis they are divided into two parts consistent and inconsistent.

A consistent system has one or more solutions while for an inconsistent system there are no solutions.

The equations are given as,

7x - 2y = -20              (1)

9x + 4y = -6               (2)

Multiply equation (1) by 2 and then add to (2) to get,

2(7x - 2y) + 9x + 4y = -20 × 2 + (-6)

⇒ 23x = -46

⇒ x = -2

Then, substitute x = -2 in equation (1) to get,

7 × -2 - 2y = -20

⇒ y = 3

Hence, the solution of the given system of equations is given as x = -2 and y = 3.

By simplifying and rearranging the given system of equations, we find that the ordered pair (s, t) that satisfies the system is (2, 1 + 2/3).

The system of equations given in the question is:
s/2 - 3t = -1
3t - 2s = 3.

We can begin solving this system by first multiplying the first equation by 2 to eliminate the fraction, giving us:
s - 6t = -2.

Next, we rearrange the second equation to be in terms of 's':
2s = 3t + 3.

We then substitute this into the first equation and solve for 't':
(3t + 3) - 6t = -2,
simplifying to:
-3t + 3 = -2,
leading us to t = 1 + 2/3.

Substituting 't' into the second equation to find 's', we get:
2s = 3(1 + 2/3) + 3, which simplifies to s = 2. Therefore the ordered pair (s,t) that satisfies the system of equations is (2, 1 + 2/3).

Answer:

Area of rectangle = 30 units

Step-by-step explanation:

vertices are (2,2),(-3,2),(2,8), and (-3,8)

Let find the distance between (2,2)  and (2,8). because they have same x values. that would be our width

distance = [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_2)^2}[/tex]

D = [tex]\sqrt{(2-2)^2 + (8-2)^2}=\sqrt(6^2) = 6[/tex]

Width = 6

Now we find distance between (2,2) and (-3,2) because they have same y values, that would be our length

distance = [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_2)^2}[/tex]

D = [tex]\sqrt{(-3-2)^2 + (2-2)^2}=\sqrt(-5^2) = \sqrt(25)= 5[/tex]

length = 5

Area of rectangle = length * width = 5*6 = 30

Answer:

Correct choice is B

Step-by-step explanation:

The quadratic function g(x) has equation [tex]g(x)=ax^2+bx+c.[/tex] Find values of a, b and c:

[tex]g(0)=2=a\cdot 0^2+b\cdot 0+c\Rightarrow c=2.[/tex]

[tex]g(2)=3=a\cdot 2^2+b\cdot 2++2\Rightarrow 4a+2b=1.[/tex]

[tex]g(4)=2=a\cdot 4^2+b\cdot 4+2\Rightarrow 16a+4b=0.[/tex]

From the last equation [tex]b=-4a[/tex] and [tex]4a-8a=1,\\ \\a=-\dfrac{1}{4},\\ \\b=1.[/tex]

The equation of the quadratic function g(x) is

[tex]g(x)=-\dfrac{1}{4}x^2+x+2.[/tex] This quadratic function determines the parabola with vertex at point (3,2). Thus,

1. The maximal value of f(x) is 4 at x=2.

2. The maximal value of g(x) is 3 at x=2.

Thus, the maximal value of f(x) is greater than the maximal value of g(x). So option B is correct.

Q2 Answer: Experimental = 60%, difference = 10%

Step-by-step explanation:

The prime numbers between 1 and 8 are: 2, 3, 5, and 7.

Theoretical: [tex]\dfrac{4(prime)}{8(total)} = 50\%[/tex]

Experimental: [tex]\dfrac{12(prime)}{20(total)} = 60\%[/tex]

    Experimental - Theoretical

=       60%            -      50%

=                     10%

Problem 1

To find the sample mean, we simply add up all the 40 items and then divide by 40

I will add up the values row by row, and then add up the subtotals to get the grand total

row1: 39+31+38+40+29 = 177

row2: 32+33+39+35+32 = 171

row3: 32+27+30+31+27 = 147

row4: 30+29+34+36+25 = 154

row5: 30+32+38+35+40 = 175

row6: 29+32+31+26+26 = 144

row7: 32+26+30+40+32 = 160

row8: 39+37+25+29+34 = 164

Add up the subtotals: 177+171+147+154+175+144+160+164 = 1292

Divide this over 40: 1292/40 = 32.2

So the sample mean is therefore 32.2

-----------------------

To find the proportion of defective items, we count the number of times a value less than 26 shows up. That happens exactly two times. The first in row 4 (at the end of this row) is where a 25 shows up. Another copy of 25 shows up in row 8 (bottom row). There are no other values that are less than 26.

Divide this count (2) over the total sample size (40) and we get 2/40 = 1/20 = 0.05

-----------------------

In summary, 32.2 will go in the first box while 0.05 will go in the second box.

========================================

Problem 2

There are 4 values we want (2,3,5,7) out of 8 total (1,2,3,4,5,6,7,8) so 4/8 = 0.50 = 50% is the theoretical probability

This is the list of values given to us (I broke it up to help make the numbers more readable)

3, 4, 5, 2, 7

1, 3, 7, 2, 6

2, 1, 7, 3, 6

1, 8, 3, 5, 6

Of that list, the primes {3, 5, 2, 7, 3, 7, 2, 2, 7, 3, 3, 5} show up. There are 12 primes in this list out of 20. So the experimental probability is 12/20 = 3/5 = 0.60 = 60%

Therefore, the answer that goes in the "experimental probability" box is 60. The answer that goes in the second box is not 50%. I think your teacher is aiming for "10" to go in the second box because 60% is 10 percentage points higher than 50% (which was the theoretical probability found earlier)

-----------------------

In summary, 60 will go in the first box while 10 will go in the second box.
