Answer:

(-2, 3)

(1, 4)

(-4, 10)

Step-by-step explanation:

You can tell if the coordinate is a solution or not by graphing it and seeing if it is in the shaded region. Since the graph is dotted, any solutions on the line will not count.

Answer:

49*

Step-by-step explanation:

There are 180 degrees in a triangle

90*+41*=131*

180*-131*=49*

Answer:

49

Step-by-step explanation:

You find the x value by first knowing that all angles in a triangle would equal 180. With that information, you add all the sides given to you which would equal 131 then subtract that from 180 to find the missing angle. Which is 49 degrees.

Answer:

(a)Dependent

(b)Both

(c)Independent

Step-by-step explanation:

a) When selections are made without replacement, the second(next) outcome is dependent of the first(previous) outcome. Therefore, we subtract one from the draw on the total.

(b)The probability of Event A and Event B is the multiplication of the probability of event A and the probability of event B. Events A and B can either be dependent or independent.

(c)When selections are made with replacement, the next outcome is independent of the previous outcome. Therefore, we say that the two events are independent.

Answer:

4.8

Step-by-step explanation:

1% of 40 is 0.4.

So, just multiply 0.4 by 12 to get 4.8

Answer:

4.8

40/100*12 = 4.8

Step by step:

8x + 2(x-7) = 7x + 3x - 14

1. distribute the 2 to the parenthese (x-7)

8x + 2x - 14 = 7x + 3x - 14

2. combine like terms

8x + 2x = 10x

7x + 3x = 10x

10x - 14 = 10x - 14

3. get your variables to one side by adding 14 to both sides

10x - 14 = 10x - 14

     + 14          +14

10x = 10x

4. solve for variable x by dividing both sides by 10

10x = 10x

/10      /10

x = x

Answers:

Becuase x=x, it can equal any value meaning there are infinite solutions.

One property used is the addition property of equality when adding 14 to both sides of the equation.

Answer:

A) Infinite solutions

B) Distributive Property of Multiplication

Step-by-step explanation:

=> 8x+2(x-7) = 7x+3x-14

(Using distributive Property to expand brackets)

=> 8x+2x-14 = 10x-14

=> 10x-14 = 10x -14

(Subtracting 10x to both sides)

=> 10x-10x-14 = -14

=> -14 = -14

So, This equation has infinite solutions.

Answer:

One solution:

3x- 5y = 8; 5x - 3y = 2

3x + 2y = 8; 4x +3y = 1

No solution:

3x - 2y = 3; 6x - 4y = 1

3x - 4y = 2; 6x - 8y = 1

Infinitely solutions:

3 x - 6y = 3; 2x - 4y = 2

A specific point on the graph represents the solution of a linear equation in the form of two variables, ax+by = c. Therefore, the system has no solution.

The arrangement of lines and the graph containing two lines, which was plotted to resolve the supplied equations, is explained by linear equations with two variables. The linear equation, as we are previously aware, depicts a straight line. We can solve the equations with the help of these diagrams, which contain unknown variables.

A specific point on the graph represents the solution of a linear equation in the form of two variables, ax+by = c, where the total of both of these numbers will equal c when the x-coordinate has been increased by a and the y-coordinate by b.

For one solution;

it will be consistent and independent

For no solution;

it will be inconsistent and independent

For many solution;

it will be consistent and dependent

3x - 2y = 3 -------------- equation (1)

6x - 4y = 1 --------------- equation (2)

18x - 12y = 18 -------------equation (3)

18x - 12y = 3 --------------- equation (4)

subtract (4) from (3)

18x - 12y = 18

Answer:

x=68 degrees

Step-by-step explanation:

all angles in a triangle add up to 180 degrees

knowing this if we look at the problem it looks like the other two angles should be 56* and 68*

now if we take the two sides 4 and 4.5 as 56* then the other should also be the same..

therefore it leaves 68* as x

Answer:

Part A:

[tex]4 + x = y[/tex]

[tex]0.5*4 + 1*x = 0.7*y[/tex]

[tex]x = 8/3\ quarts\ of\ 100\%\ solution[/tex]

[tex]y = 20/3\ quarts\ of\ 70\%\ solution[/tex]

Part B:

[tex]x + y = 10[/tex]

[tex]2x + 3y = 23[/tex]

[tex]x = 7[/tex] and [tex]y = 3[/tex]

Step-by-step explanation:

Part A:

The inicial concentration of the lemonade is 50%, and the volume is 4 quarts, and we will add x quarts of a lemonade with a concentration of 100%, so the total volume will be y, and the concentration will be 0.7, so we have that:

[tex]4 + x = y[/tex]

[tex]0.5*4 + 1*x = 0.7*y[/tex]

Using the value of y from the first equation in the second one, we have:

[tex]2 + x = 0.7*(4 + x)[/tex]

[tex]2 + x = 2.8 + 0.7x[/tex]

[tex]0.3x = 0.8[/tex]

[tex]x = 8/3\ quarts[/tex]

[tex]y = 4 + 8/3 = 20/3\ quarts[/tex]

Part B:

If he shoots a total of ten targets, we can write the equation:

[tex]x + y = 10[/tex]

Each stationary target is 2 points, and each moving target is 3 points, so if the total points is 23, we have:

[tex]2x + 3y = 23[/tex]

If we subtract the second equation by two times the first one, we have:

[tex]2x + 3y - 2*(x + y) = 23 - 2*10[/tex]

[tex]2x + 3y - 2x - 2y = 23 - 20[/tex]

[tex]y = 3[/tex]

[tex]x + 3 = 10[/tex] ⇒ [tex]x = 7[/tex]

Answer:

431,707

Step-by-step explanation:

To figure out the total number, you need to divide the part of the whole by the percentage it is of the whole.  This means that you need to divide 35,400 by 8.2%.

Before dividing the percentage, you need to convert it to a decimal.

8.2% = 0.082

Divide the number to find the answer.

35,400/0.082 = 431,707.3

Converted to the nearest whole number, the answer is 431,707.

Answer: Resistance = 0.8106 ohms.

Step-by-step explanation:

Electrical resistance is proportional to the length of a wire.

The relationship between resistance and length of a wire can be expressed as;

L1/R1 = L2/R2

Let L1 = 160 ft, R1 = 16.212 ohms

L2 = 8ft, R2 = ?

Substitutes all the parameters values into the formula

160/16.212 = 8/R2

Cross multiply

160R2 = 129.696

R2 = 129.696/160

R2 = 0.8106 ohms.

Therefore, the resistance of 8 ft. of wire will be 0.8106 ohms.

Answer:

72 cm²

Step-by-step explanation:

The diagonal of the square divides the square into 2 right triangles.

let the legs of the triangle be x , then using Pythagoras' identity.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

The hypotenuse of the triangle is the diagonal, thus

x² + x² = 12²

2x² = 144 ( divide both sides by 2 )

x² = 72 ( take the square root of both sides )

x = [tex]\sqrt{72}[/tex]

The area of the square = x² = ([tex]\sqrt{72}[/tex] )² = 72 cm²

Answer: 72 sq. in.

Step-by-step explanation:

A = a^2

D = √2 a

Solving for A

A = 1/2 x d^2

= 1/2 x 12^2

= 1/2 x 144

= 72 sq in

Answer:

64, 68, 74, 76

Step-by-step explanation:

Ok so in a confusing way, the last two statements are telling you that the number is greater than 8^2, which is 64, and the number is less that 9^2, which is 81.

The number has to be even, so I will list the even numbers between those two numbers:

64, 66, 68, 70, 72, 74, 76, 78, 80.

It cannot be divisible by 3, which rules out 66, 72, 78

64, 68, 70, 74, 76, 80 remains

It cannot be divisible by 5, which rules out 70 and 80

64, 68, 74, 76  are the possible answers,

*Note: I believe I did this right, but because of the tricky wording of the last two statements, 64 may not be included.
