y = 2x

Step-by-step explanation:

The linear functions are given by:

y = mx+b

To find the slope, we have to find the change in x and y

The change in x is:

[tex]-14-(42) =-14+42 =28\\14+14= 28[/tex]

The change in y is:

[tex]-28-(-84) = -28+84 = 56\\28-(-28) = 28+28 = 56[/tex]

The slope is:

[tex]Slope = \frac{change\ in\ y}{Change\ in\ x}\\=\frac{56}{28}\\= 2[/tex]

Putting slope in equation of linear function

[tex]y =2x+b[/tex]

To find the value of b, we will put any pair of input and output in the slope-intercept form

So, putting (14,28)

[tex]28 = 2(14) + b\\28 = 28+b\\b = 28-28\\b = 0[/tex]

Hence,

the linear equation for function is:

y = 2x

Answer:

[tex]6.5 \times 10^{-9}[/tex]

Step-by-step explanation:

The scientific notation of a number is to express the number in the form [tex]x\times 10^{y}[/tex] where x is the base of ten.

So, if we want to express the number 0.0000000065, then we can write it as

[tex]\frac{6.5}{1000000000} = 6.5 \times 10^{-9}[/tex].

So, we can write 0.0000000065 as [tex]65\times 10^{-10}[/tex] or [tex]0.65 \times 10^{-8}[/tex] but those are not the scientific notation.  

Therefore, [tex]6.5 \times 10^{-9}[/tex] is the scientific notation of 0.0000000065. (Answer)

The function through the points (10, 18), (14, 24), and (18, 30) is a direct variation function with a constant of variation of 1.8.

In this case, we have a linear function. We can determine this by checking if the changes between the x-values and the y-values are consistent. For the change in x-values: (14-10 is 4) and (18-14 is also 4), the change is constant. Similarly, check the change in y-values: (24-18 is 6) and (30-24 is also 6), thus the change is constant. Hence, the function is linear.

More so, this function is a direct variation function because it passes through the origin. In direct variation functions, the ratio of y to x remains constant. In this case, the y divided by x at each point [(18/10=1.8), (24/14=1.71), (30/18=1.67)] is approximately 1.8, which is almost constant.

So, the best description of this function is: 'The function is a direct variation function with a constant of variation of 1.8'.

[tex]22 - 7 \div 3.50[/tex]

Answer:

Computer can be rented for  42.85 minutes using $22

Step-by-step explanation:

Given:

Setup charge =  ​$ 7

Additional charge for every 10 minutes = ​$ 3.50

To find:

The time for which the computer can be rented for  ​$ 22

Solution:

Let the additional time be x

for  additional charge for 10 minutes =3.50

for 1 minute , additional charge = [tex]\frac{3.50}{10}[/tex]= $0.35

According to the question

setup cahrge + additional charge= $22

[tex]7+(0.35\times x)=22[/tex]

[tex](0.35\times x)=22-7[/tex]

Answer:  x = -13

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

Work Shown:

19 = 38/2

19 & 1/2 = 19 + 1/2

19 & 1/2 = 38/2 + 1/2

19 & 1/2 = (38+1)/2

19 & 1/2 = 39/2

-------

In the original equation, replace the "19 & 1/2" with "39/2" to get

(5/2)x + (1/2)x = 39/2 + (9/2)x

Each term involves a fraction with a denominator of 2. If we multiply both sides by the common denominator, then the fractions will cancel out

For example: 2*(5/2)x = (10/2)x = 5x

So after multiplying both sides by 2, you should have this new equation

5x + 1x = 39 + 9x

--------

Let's solve that latest equation for x

5x + 1x = 39 + 9x

6x = 39 + 9x

6x-9x = 39 + 9x-9x ... subtract 9x from both sides

-3x = 39

-3x/(-3) = 39/(-3) .... divide both sides by -3

x = -13

33.3/30=1.11

1.16-1.11=0.05

The correct statement is The unit rate per pound of a 14 pound bag is $0.05 more than the unit rate of a 30 pound bag.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

14 pound bag cost = 16.24

cost of 1 pound bag = 16.24/14

                                  = $1.16

and,

another bag which is of  30 pound costs = 33.30

                                                                    = 33.30 / 30

                                                                    = $1.11

When reflected over x-axis a graph becomes negative in y value.

f(x) = -|x| then translate 1 unit to the right is f(x) = -|x| + 1. Adding 1 translates the graph towards the right because the positive x-axis is on the right.

To minimize production cost, we need to find the dimensions of the package that will satisfy the volume equation and minimize the cost equation. Taking the partial derivatives of the cost equation with respect to the variables 'r' and 'h', and setting them equal to zero, we can find the critical points. Solving these equations, we find that the dimensions for the package that will minimize production cost are a height of 7 cm and a radius of 2.5 cm.

To find the dimensions of the package that will minimize production cost, we need to consider the cost of the sides and bottom made of styrofoam and the cost of the top made of glued paper. Let's denote the radius of the base of the cylinder as 'r' and the height of the cylinder as 'h'.

The volume of a cylinder is given by the formula V = πr²h. We know that the volume of the package needs to be 350 cubic centimeters, so we can write the equation as πr²h = 350.

The cost of the sides and bottom of the container is given by the formula C1 = 0.03 * (2πrh + πr²), and the cost of the top is given by the formula C2 = 0.08 * πr².

To minimize the cost, we need to find the values of 'r' and 'h' that satisfy the volume equation and minimize the cost equation.

Since this is a calculus problem, we will differentiate the cost equation with respect to 'r' and 'h', and set the derivatives equal to zero to find the critical points.

Taking the partial derivatives of C1 and C2 with respect to 'r' and 'h', we get:

Solving these equations, we find that h = 7 cm and r = 2.5 cm. Therefore, the dimensions for the package that will minimize production cost are a height of 7 cm and a radius of 2.5 cm.

If [tex]y[/tex] is inversely propotional to the square of [tex]x[/tex], then the relation would be like

[tex]y=\frac{K}{x^{2} }[/tex]

Where [tex]K[/tex] is the constant of propotionality.

Now, we need to use a pair from the table to find the constant of proportionality, we are gonna use [tex](1,4)[/tex]

[tex]y=\frac{K}{x^{2} }\\4=\frac{K}{(1)^{2} } \\K=4[/tex]

Replacing this constant, the expression between variables is

[tex]y=\frac{4}{x^{2} }[/tex]

Which is the answer to a).

Now, if [tex]y=25[/tex] the value of [tex]x[/tex] would be

[tex]y=\frac{4}{x^{2} }\\25=\frac{4}{x^{2} }\\x^{2} =\frac{4}{25}\\ x=\sqrt{\frac{4}{25} }\\ x=\frac{2}{5}[/tex]

Therefore, the answer to b) is [tex]x=\frac{2}{5}[/tex]

In an inverse variation, y is inversely proportional to the square of x. To express y in terms of x, the equation is y = k/(x^2). To find the positive value of x when y = 25, the equation is 25 = k/(x^2), and x = sqrt(k/25) is the solution.

In an inverse variation, a variable is inversely proportional to another variable if their product is a constant. In this case, y is inversely proportional to the square of x. We can write this relationship as y = k/x^2, where k is the constant of variation.

To express y in terms of x, we can rearrange the equation as y = k/(x^2).

To find the positive value of x when y = 25, we can substitute these values into the equation and solve for x. We have 25 = k/(x^2). Rearranging the equation gives us k = 25x^2. Since we want to find the positive value of x, we can take the square root of both sides to get x = sqrt(k/25).

Answer:

The Value of x= 7.

m∠A= 21°

m∠B= 80°

m∠C= 79°

Step-by-step explanation:

Given:

m∠A = 2x+7

m∠B = 10x+10

m∠C = 8x+23

We need to find the value of x and measures of each angle.

Now by angle sum property which states that sum of all angles of a triangle are 180°.

Hence from above statement we can say in ΔABC;

m∠A+m∠B+m∠C=180

Now substituting the given values in above equation we get;

[tex]2x+7+10x+10+8x+23=180\\2x+10x+8x+7+10+23=180\\20x+40=180\\20x=180-40\\20x=140\\\\x=\frac{140}{20} =7[/tex]

Hence value of x is 7.

Substituting the value of x in all angles we get;

m∠A=[tex]2x+7=2\times7+7=14+7=21\°[/tex]

m∠B=[tex]10x+10=10\times7+10=70+10=80\°[/tex]

m∠C=[tex]8x+23= 8\times7 +23 = 56+23=79\°[/tex]

Final answer:

To find the value of x and the measure of each angle in triangle ABC, set up an equation using the given angle measures. Solve for x and substitute it back in to find the measures of each angle. Then : m<A = 2(7) + 7 = 21 degrees

m<B = 10(7) + 10 = 80 degrees

m<C = 8(7) + 23 = 79 degrees

Explanation:

To find the value of x and the measure of each angle in triangle ABC, we need to set up an equation using the given angle measures. Since the sum of the angles in a triangle is 180 degrees, we can write the equation as:

m<A + m<B + m<C = 180

Substituting the given angle measures, we have:

(2x + 7) + (10x + 10) + (8x + 23) = 180

Simplifying the equation:

20x + 40 = 180

Subtracting 40 from both sides:

20x = 140

Dividing both sides by 20:

x = 7

Now that we know the value of x, we can find the measure of each angle by substituting x into the respective expressions:

m<A = 2(7) + 7 = 21 degrees

m<B = 10(7) + 10 = 80 degrees

m<C = 8(7) + 23 = 79 degrees
