What is a system of linear equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

It is given that in a coordinate grid with 2 lines. The first line labelled f(x) passes through (-3, 3), (0,2), and (3, 1). The second line labelled g(x) passes through the points at (-3, 0) and (0, 2).

Plotting the two lines by using the points on the graph. After plotting the points there will be two lines that will intersect at the point ( 0, 2 ). Then the solution of the equation is ( 0,2).

Therefore, the solution to the system of linear equations is (0,2). The correct option is C.

At a concession stand, seven hot dogs and two hamburgers cost 14.50, two hot dogs and seven hamburgers cost 17.00. Find the cost of one hot dog and the cost of one hamburger

Answers

Given:

Seven hot dogs and two hamburgers cost 14.50

Two hot dogs and seven hamburgers cost 17.00.

To find:

The cost of one hot dog and the cost of one hamburger.

Solution:

Let the cost of one hot dog be x and the cost of one hamburger be y.

According to the question,

[tex]7x+2y=14.50[/tex]       ...(i)

[tex]2x+7y=17.00[/tex]       ...(ii)

Multiply (i) by 7.

[tex]49x+14y=101.5[/tex]       ...(iii)

Multiply (ii) by 2.

[tex]4x+14y=34.00[/tex]       ...(iv)

Subtract (iv) from (iii).

[tex]49x-4x=101.5-34[/tex]  

[tex]45x=67.5[/tex]  

Divide both sides by 45.

[tex]x=1.5[/tex]  

Put x=1.5 in (i).

[tex]7(1.5)+2y=14.50[/tex]

[tex]10.50+2y=14.50[/tex]

[tex]2y=14.50-10.50[/tex]

[tex]2y=4[/tex]

Divide both sides by 2.

[tex]y=2[/tex]

Therefore, the cost of one hot dog is 1.5 and the cost of one hamburger is 2.

Given f(x) = 5(x + 1) + 16 , what is the value of x when f(x) = 1 ?

Answers

Answer:

x = -4

Step-by-step explanation:

1=5(x+1)+16

1=(5)(x)+(5)(1)+16 (Distribute)

1=5x+5+16

1=(5x)+(5+16)(Combine Like Terms)

1=5x+21

5x+21=1

5x+21−21=1−21

5x=−20

5x/5=−20/5

x=−4

Answer:

value of x is -4

Step-by-step explanation:

All you need to do is replace f(x) for 1.

1 = 5(x+1) + 16

backwards solve;

1 = 5x+5 +16

1=5x+21

1-21=5x

-20=5x

x=-4

That's all.

If it asks you if x=1, then just plug in 1 where ever x is. f(x) is symbolic of y.

Shannon is making identical balloon arrangements for a party. She has 32 maroon balloons, 24 white balloons, and 16 orange balloons. She wants each arrangement to have the same number of each color. What is the greatest number of arrangements that she can make if every balloon is used?

Answers

Answer:

8

Step-by-step explanation:

Given that:

Number of white balloon = 24

Number of maroon Ballon = 32

Number of orange Ballon = 16

To obtain the greatest number of arrangements ;

Find the greatest common factor of 24, 16 and 32

Factors of ;

24 = 1, 2, 4, 6, 8, 12, 24

16 = 1, 2, 4, 8, 16

32 = 1, 2, 4, 8, 16, 32

Hence, the greatest factor common to all three is : 8

Hence greatest number of arrangement that can be achieved is 8

B 18 drops of chili oil for every 5 cups of chicken broth

C 20 drops of chili oil for every 4 cups of chicken broth

D 22 drops of chili oil for every 4 cups of chicken broth

Answers

Answer:

Yvonne should pick mixture B which has a lesser concentration of chili oil.

Step-by-step explanation:

Bob's soup concentration = 18 drops / 4 cups = 9 drops / 2 cups = 4.5 drops/cup

A. 18 / 2 = 9 drops/cup which is a greater concentration

B. 18 / 5 = 3.6 drops/cup which is a lesser concentration

C. 20/ 4 = 5 drops/cup which is a greater concentration

D. 22/ 4 = 5.5 drops/cup which is a greater concentration

If the trapezoid is isosceles, and KL = 2.8 units in length, what is the length of NM? Explain how you determined the length of NM.

Answers

Answer:

MN = 2.8 units

Step-by-step explanation:

By the property of isosceles trapezoid,

1). Bases are parallel.

2). Base angles of an isosceles trapezoid are congruent.

2). Opposite sides of the congruent angles are congruent.

By third property,

Measure of side KL = Measure of side MN

2.8 = Measure of side MN

Another way to find the length of MN is,

Distance between M and N = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

MN = [tex]\sqrt{(3-1)^2+(0+2)^2}[/tex] = [tex]\sqrt{8}[/tex]

MN = 2.8 units

Therefore, MN = 2.8 will be the answer.
