Answer:

  (graph, table, equation) = (1, 5, 2), (2, 3, 1), (3, 2, 4), (4, 4, 5), (5, 1, 3)

Step-by-step explanation:

The graphs have the following (slope, intercept), so can be easily matched with the corresponding equation.

  (1/2, 1), (2, -1), (1, 2), (1/2, -1), (-2, -1)

We can look at the points in the tables to see which graph they appear on.

Table 1, (-2, 3) is on graph 5

Table 2, (-3, -1) is on graph 3

Table 3, (-1, -3) is on graph 2

Table 4, (-2, -2) is on graph 4

Table 5, (4, 3) is on graph 1

__

Then our triples of graph, table, equation are ...

  (1, 5, 2), (2, 3, 1), (3, 2, 4), (4, 4, 5), (5, 1, 3)

Rewrite the equation from Part D by factoring the side that contains the variable p.
Previous equation answer for Part D (for context): r = 65 - 60p

Answers

Answer: r = 5(13-12p)

Step-by-step explanation:

To factor, take out the GCF (the largest number that can be taken out of the equation to leave all numbers as whole numbers). In this case, the largest number that can be taken out of the equation is 5.

Take 5 out from the equation and put it outside of the parenthesis (a factor). Divide 65 and -60p by 5 to find the value of the numbers within the parenthesis.

After doing so, you will have your equation factored.

The simplification of  r = 65 - 60p is r = 5(13-12p).

What is the greatest common factor?

The biggest integer that can split the numbers evenly.

The term "largest common factor" refers to it.

Given equation,

r = 65 - 60p

To rewriting the equation by factoring the side:

For that, we take the greatest common factor,

r = 65 - 60p

GCF of 65 and 60 is 5.

So, r = 65 - 60p

r = 5(13-12p)

Therefore, the answer is r = 5(13-12p).

Use the identity (x+y)(x2−xy+y2)=x3+y3 to find the sum of two numbers if the product of the numbers is 28, the sum of the squares is 65, and the sum of the cubes of the numbers is 407.

Answers

Answer:

Step-by-step explanation:

1) f(x) = x+y , xy = 49 --> f(x) = x+49/x

f '(x) = 1-49/x2 , x = ±√49 , choose x = +7

y = 49/x = 7

smaller = 7

larger = 7

2) Vertical Distance is difference between the two functions

V(x) = x+56 - x2, V '(x) = 1 -2x --> x = 1/2 --> V(1/2) = 56.25 <---Max Vertical distance

Boundary at -7 and 8 are less

3) I googled the equation, it is really y(n) = kn/(49+n2)

y '(n) = (k(49+n2) - 2kn2)/(49+n2) , Setting to zero, k(49+n2) -2kn2 = 0 , n = 7

4) Let x and y be the sides of the rectangle. A = xy = 37.5 Million or y = 37.5/x

The length of the fences is f(x) = 2x + 3y = 2x+112.5/x

f '(x) = 2-112.5/x2 --> x = √56.5 = 7.5 and y = 37.5/7.5 = 5 then scale by √Million

smaller = 5000 ft and larger = 7500 ft

this took me ages to work out so hopefully it helped

Answer:

x + y = 11

Step-by-step explanation:

xy = 28

x² + y² = 65

x³ + y³ = 407

(x + y)(x² - xy + y²) = x³ + y³

(x + y)(x² + y² - xy) = x³ + y³

(x + y)(65 - 28) = 407

37(x + y) = 407

x + y = 407÷37

x + y = 11

4/7 divide by 3/8 = 7/4 * 3/8 = 21/32

To divide 4/7 by 3/8, keep 4/7 and multiply by the reciprocal of 3/8, so do the multiplication below:

If $(2x+5)(x-3)=14$, find the sum of the possible values of $x$.

Answers

Answer:

x = 1/4 ± 1/4√233

Step-by-step explanation:

(2x + 5)(x - 3) = 14

~Use FOIL on the left side

2x² - 6x + 5x - 15 = 14

~Combine like terms

2x² - x - 15 = 14

~Subtract 14 to both sides

2x² - x - 29 = 0

~Use the quadratic formula and simplify

x = 1/4 ± 1/4√233

Find the Y-Intercept
-3x + 7Y = 21

Answers

The answer is 3
Trust me dog

Answer:

(0, 3)

Step-by-step explanation:

To find the y-intercept of a linear equation, we simply need to put the equation into "slope-intercept" form.  This will allow the y-intercept to be shown as the constant being added to the equation.  To put a linear equation into slope-intercept form, we simply need to solve for Y.  Let's do that.

-3x + 7Y = 21

3x + -3x + 7Y = 3x + 21

7Y = 3x = 21

(1 / 7) * 7Y = (3x + 21) * (1 / 7)

Y = (3x / 7) + (21 / 7)

Y = 3x/7 + 3

Now that we have the Y isolated, we can see the constant being added is 3.  Hence, the y-intercept is (0,3) since by definition the y-intercept is the point at which the line crosses the x axis (where x = 0).  If you plug x=0 into the equation, you get Y = 3.

Cheers.

Answer:

Step-by-step explanation:

Since we know x=18, we need to find 2/3 of 18.

Let's make 2/3 so that the denominator(bottom part of a fraction) is 18.

18 divided by three is six so we needs to times the top number, 2, by 6.

The fraction would now be 12/18. Now we needs to subtracts 12 which would become 0/18. This equals 0.
