Answer:

3x - 7y = 14

Step-by-step explanation:

standard form is: ax + by = c

first, add 2 to each side of the equation to get:

2 + y = 3/7x

now multiply each term by 7 to eliminate fraction:

14 + 7y = 3x

now subtract 7y from each side to get:

3x - 7y = 14

Answer:  j(x) = (x-1)(x+2)

The x-1 part is because of the root x = 1

The root x = -2 leads to the factor x+2

The ordered pairs that represent points on the graph of y = 2x - 3 are (0,-3), (5,7), (-2,-7), (2,1), and (4,5).

An ordered pair is a pair of numbers written in a specific order (x,y) that represents a point in the coordinate plane.

A graph is a visual representation of data or a mathematical function that is plotted on a coordinate plane, usually with an x and y-axis. It is used to analyze trends and relationships between variables.

According to the given information:

To determine whether a given ordered pair represents a point on the graph of the equation y = 2x - 3, we need to substitute the values of x and y into the equation and see if the equation is true.

a) (3,-3):

y = 2x - 3

-3 = 2(3) - 3

-3 = 3

This is not true, so (3,-3) is not on the graph.

b) (0,-3):

y = 2x - 3

-3 = 2(0) - 3

-3 = -3

This is true, so (0,-3) is on the graph.

c) (5,7):

y = 2x - 3

7 = 2(5) - 3

7 = 7

This is true, so (5,7) is on the graph.

d) (-2,-7):

y = 2x - 3

-7 = 2(-2) - 3

-7 = -7

This is true, so (-2,-7) is on the graph.

e) (2,1):

y = 2x - 3

1 = 2(2) - 3

1 = 1

This is true, so (2,1) is on the graph.

f) (4,5):

y = 2x - 3

5 = 2(4) - 3

5 = 5

This is true, so (4,5) is on the graph.

Therefore, the ordered pairs that represent points on the graph of the equation y = 2x - 3 are: (0,-3), (5,7), (-2,-7), (2,1), and (4,5). Answer: b), c), d), e) and f).

Answer:

$47.48

Step-by-step explanation:

Let x = the amount owed Sept.

x + x - 2.23 = 292.43  Combine like terms

2x -2.23 = 292.43  Add 2.23 to both sides

2x - 2.23 + 2.23 = 292.43 + 2.23

2x = 294.66  Divide both sides by 2

\(\frac{2x}{2}\) = \(\frac{294.66}{2}\)

x = 147.33 this is the bill for September

Oct. 147.33 -2.23 = 145.10 This is the Bill for Oct.

Total:

147.33 + 145.10 = 292.43

292.43 ÷ 3 = 97.48  This is what each will owe rounded to the nearest penny.

Answer:

See Below:

Step-by-step explanation:

Average is take by adding all the terms together and dividing by the number of terms. In this case it terms is people in the room.

22= (25+18+17+13+24+x)/6

Where 22 is the average age. The numerator is all the known ages added together, plus x which is the age of the person who just entered. Divided by 6 because you are finding the average age of 6 people.

22 = (25+18+17+13+24+x)/6     Multiply both sides by 6

132= 97+ x  Subtract 97 from both sides.

35 = x

The person who just entered the room is 35 years old.

the value of k for the given right-angle triangles is 5.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given, Two right-angle triangles one of them has a height of 7 cm and a weight of 1 cm. While others have a height and base of the same measurement k.

The Hypotaneuse of the triangles is equal and the same.

From the general formula of the Pythagorean theorem

Hypotaneuse²  = height + bsase²

in a triangle with a height of 7

Hypotaneuse² = 7² + 1²

Hypotaneuse² = 49 + 1

Hypotaneuse² = 50...(1)

In a triangle with a height of k

Hypotaneuse² = k² + k²

Hypotaneuse² = 2k²....(2)

Since Hypotaneuse is the same

From comparing both equations

50 = 2k²

k² = 25

k = 5

therefore, the value of k for the given right-angle triangles is 5.

Answer:

  x < 0.3

Step-by-step explanation:

This is similar to a 3-step linear equation, but you need to do a little simplification first.

  2x +2 < -(x +4.1) +7

  2x +2 < -x -4.1 +7 . . . . . . eliminate parentheses (distribute the minus sign)

  2x +2 < -x +2.9 . . . . . . . . combine constant terms

From this point, we can solve the equation exactly the same way we would for a 3-step linear equation.

  3x +2 < 2.9 . . . . . . . . add x to both sides to get all x-terms in one place

  3x < 0.9 . . . . . . . . . . . subtract 2 from both sides to get x-terms alone

  x < 0.3 . . . . . . . . . . . divide both sides by 3 to get x alone

Additional comment

The only difference from solution of linear equations comes when you multiply or divide by a negative number. In those cases, the inequality symbol reverses. Consider ...

  -1 > -2

  1 < 2 . . . . . . multiplying both sides by -1 reversed the order

Step-by-step explanation:

The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

How many different choices could I make?

3 cards from a set of 52(number of cards on a standard deck).

4 Pokemon cards from a set of 10. So

\(T = C_{52,3}*C_{10,4} = \frac{52!}{3!49!}*\frac{10!}{4!6!} = 22100*210 = 4641000\)

The marginal revenue when q = 29 is 510 dollars.

To find the marginal revenue we need to differentiate the revenue equation, here we know that:

R(q) = -5q² + 800q

Differentiating that, we will get:

R'(q) = MR(q) = 2*(-5)*q + 800

                     = -10q + 800

The marginal revenue when q = 29 is

MR(29) = -10*29 + 800 = 510
