Answer:

you have the values of a, b and c

all you gotta do is just plug them in so

ab+bc is (3)(6)+(6)(5)

which equals 48.

Answer:

48

Step-by-step explanation:

since a=3, b=6 and c=5, you would replace the letters in ab+bc with their numbers, making it (3)(6)+(6)(5). then you would multiply 3 x 6 which would be 18, and 6 x 5, which would be 30, making your expression 18+30. finally you would add them together, making it 48.

Incomplete question.

hmmm first of all, let's keep in mind that any expression multiplied by 1 is always the same expression

[tex]12\cdot 1=12\qquad 13567\cdot 1=13567\qquad spaghetti\cdot 1=spaghetti[/tex]

and so on.

now, hmm 1 can be expressed as a rational, 1/1 = 1, but but but, we can really express it as

[tex]\cfrac{9999}{9999}\implies \cfrac{7857}{7357}\implies \cfrac{\sqrt[11]{1375}}{\sqrt[11]{1375}}\implies \cfrac{spaghetti}{spaghetti}\implies \cfrac{lettuce}{lettuce}\implies \text{\Huge 1}[/tex]

so let's do the so-called rationalizing of the denominator, we can also do it with the numerator btw, but we only need it for the denominator right now, by multiplying for 1 :), 1 is Da Bomb baby!!

[tex]\cfrac{5}{2\sqrt{5}}\cdot \text{\LARGE 1}\implies \cfrac{5}{2\sqrt{5}}\cdot \cfrac{\sqrt{5}}{\sqrt{5}}\implies \cfrac{5\sqrt{5}}{2\sqrt{5^2}}\implies \cfrac{5\sqrt{5}}{2(5)}\implies \cfrac{5\sqrt{5}}{10}\implies {\Large \begin{array}{llll} \cfrac{\sqrt{5}}{2} \end{array}}[/tex]

1.The slope -intercept form of the function is  y = 7x

2.The slope -intercept form of the function is y = x - 8

3.The slope -intercept form of the function is y = -2x +9

4.The slope -intercept form of the function is [tex]y = \frac{1}{3}x+9[/tex]

5.The slope -intercept form of the function is  y = 0.5x - 1.5

6.The slope -intercept form of the function is   y = 3x - 12

How is the slope -intercept form calculated?

1. The slope -intercept form of the equation of the function is  y = 7x

Slope = m

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m =\frac{0+7}{0+1} \\\\m= 7[/tex]

Substituting point (-1,-7)  and m in the slope-intercept form of the equation,

y = mx+ c   ----(1)

-7 = 7(-1) + c

c = 7 -7

c = 0

Substituting m and c in  (1)

y = 7x

2. The slope -intercept form of the equation of the function is y = x - 8

Slope = m

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m =\frac{-8+17}{0+9} \\\\m= \frac{9}{9} =1[/tex]

Substituting point (-9,-17)  and m in the slope-intercept form of the equation,

y = mx+ c   ----(1)

-17 = (-9) + c

c = -17 +9

c = -8

Substituting m and c in  (1)

y = x - 8

3. The slope -intercept form of the equation of the function is y = -2x +9

Slope = m

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m =\frac{5-9}{2-0} \\\\m= \frac{-4}{2} =-2[/tex]

Substituting point (0,9)  and m in the slope-intercept form of the equation,

y = mx+ c   ----(1)

9 =  -2 (0) + c

c = 9

Substituting m and c in  (1)

y = -2x +9

4.The slope -intercept form of the equation of the function is  [tex]y = \frac{1}{3}x+9[/tex]

Slope = m

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m =\frac{8-7}{-3+6} \\\\m= \frac{1}{3}[/tex]

Substituting point (0,9)  and m in the slope-intercept form of the equation,

y = mx+ c   ----(1)

9 =  1/3 (0) + c

c = 9

Substituting m and c in  (1)

[tex]y = \frac{1}{3}x+9[/tex]

5. The slope -intercept form of the equation of the function is

y = 0.5x - 1.5

Slope = m

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m =\frac{1-0.5}{5-4} \\\\m= \frac{0.5}{1}= 0.5[/tex]

Substituting point (5,1)  and m in the slope-intercept form of the equation,

y = mx+ c   ----(1)

1 =0.5 (5) + c

1 -2.5 = c

c = - 1.5

Substituting m and c in  (1)

y = 0.5x - 1.5

6. The slope -intercept form of the equation of the function is y = 3x - 12

Slope = m

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\m =\frac{9-3}{7-5} \\\\m= \frac{6}{2}\\\\m= 3[/tex]

Substituting point (5,3)  and m in the slope-intercept form of the equation,

y = mx+ c   ----(1)

3 =3(5) + c

3 -15 = c

c = - 12

Substituting m and c in  (1)

y = 3x - 12

The x intercepts of the function given in the question will be equal to x = 6 and x = 3.

A function may be defined as an entity in which for one value of input there is only one value of output. The input value is the value of x variable, or the independent variable and the output value is the value of y variable or the dependent variable. For example, f(x) = y = x + 2, in this function for the value of input x = 1 the value of output is y = 3. The x intercept of a function may be defined as the point on the graph at which the line of function crosses the x axis. For finding the x intercept the y value or the value becomes zero. We are given the function g(x) = (1/4) (x - 6) (x - 3)

Now, g(x) = 0

(1/4) (x - 6) (x - 3) = 0

=> (x - 6) (x - 3) = 0

=> x = 6 and x = 3

Therefore, x intercepts are x = 6 and x = 3.

The revenue of the the agency is given by the function

R(x) = 5000 - 50 x - 3x² .

A function is a relationship between an independent variable and a dependent variable which defines all points on a cartesian plane which satisfies the given condition.

Now in the given Agency it is given that the charge of each tourist is $100 . Now for every tourist above 50 the charge is reduced by 3 dollars.

So for x people above 50 charge will be ( 100-3 x ) for all members.

The total revenue can be measured by the function

R(x) = ( 50 + x ) ( 100 - 3x )

or , R(x) = 5000 - 150 x + 100 x - 3x²

or, R(x) = 5000 - 50 x - 3x²

Hence the revenue function is given as : R(x) = 5000 - 50 x - 3x²

Answer:

there are 720 three digit numbers that can be created from the digits provided given that no digit may be repeated.

Step-by-step explanation:

Answer:

The original price was 18 dollars.

Step-by-step explanation:

Givens

Final price = 15 dollars

Discount = 20%

Original Price = x

Formula

x = 15 + 20/100 15

Solution

x = 15 + 300/100                     Multiply 20 * 15. Divide by 100

x = 15 + 3

x = 18

Note the - sign in the evaluation of f(x), which changes the function directly, and the term -4 indicates a displacement vertically (down), but the graph goes up because of the sign -, therefore, the only option with these conditions is option b.

The correct answer is option b.

Answer:

x = 21

Step-by-step explanation:

1. Set x equal to the amount of money Jim has

2. Create equations of the amount of money the other people have based on x

3. Now, we set all of these equations as equal to 68

5. Add 8 to both sides

6. Divide 76 by 4

7. Plug the value of x into the previous equations:

Final Answer:

Reason:

The smallest |x-5| can get is 0 since the result of an absolute value is never negative (because it represents distance).

So the smallest f(x) = |x-5|-3 can get is 0-3 = -3

f(x) = -3 or f(x) > -3 are the only two options for the output f(x).

The rational number that can be written as a decimal in which one or more nonzero digits repeat is given by:

D. 5/9.

The set of rational numbers is composed by numbers that can be represented by fractions, such as numbers that have no decimal parts, or numbers in which the decimal parts are terminating or repeating.

For this problem, we have a focus on numbers that have repeating decimal part. The most known case is the division by 9, as when an integer that is not a multiple of 9 is divided by 9, the result is a decimal with a repeating decimal part.

To find the equivalent decimal to 5/9, we divide the numerator of 5 by the denominator of 9, hence:

The new quantity supplied when the price is $348 per cord is  424.

The supply curve is a graph that shows the relationship between price and quantity supplied. The supply curve has a positive slope.

The slope of the supply curve is the ratio of the change in the value of price divided by the change in the value of the quantity supplied.

Slope = change in price / change in quantity supplied

0.75 = ($348 - $255) /  change in quantity supplied

0.75 = $93 /  change in quantity supplied

change in quantity supplied = 93 / 0.75 = 124

where l = base length, w = base width and h = height

The volume of this pyramid

New Volume [tex]= \dfrac{18\cdot 12\cdot 21}{3} = 1512\; cm^3[/tex]

[tex]6t = \$ 40[/tex]

Then, we can multiply both sides of the equation (proportion) by something such that the number of dollars on the right side is $200.
