Step-by-step explanation: 34% of 19 is 6.46 and 1/3*18=18/3=6 so its the closest out of the others

Step-by-step explanation:

The systems of linear equations can have:

1. No solution: When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.

2. One solution: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system

3. Infinitely many solutions: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.

Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts never have more than one solution.

Answer:

332

Step-by-step explanation:

Since Dana had the closest guess with 325 people and Elijah had the second closest guess with 340 people we know that the actual number of guests is close to these values. Since Brady had the farthest guess then that means that the actual number of guests is higher than 325 and lower than 340. Therefore the actual number of guests can only be 332 as it is between Dana and Elijah's guesses but still favoring Dana, and also being farthest from Brady's guess.

Answer:

x= 40

Step-by-step explanation:

The reason this is so is because a straight line's degree is always 180. And 4(40)-20=140 and 180-40=140. This is how you would work out the right side. This gives you your answer.

Answer:

40

Step-by-step explanation:

[tex]x + 4x - 20 = 180 \\ 5x = 180 + 20 \\ x = 200 \div 5 \\ x = 40[/tex]

Answer:

d = all real numbers

Step-by-step explanation:

-9d-8= -4 (d + 2) - 5d

-9d - 8 = -4d - 8 - 5d

-9d - 8 = -9d - 8

0d - 8 = -8

0d = 0

d = all real numbers

Answer:

The values of x for which the model is 0 ≤ x ≤ 3

Step-by-step explanation:

The given function for the volume of the shipping box is given as follows;

V = 2·x³ - 19·x² + 39·x

The function will make sense when V ≥ 0, which is given as follows

When V = 0, x = 0

Which gives;

0 = 2·x³ - 19·x² + 39·x

0 = 2·x² - 19·x + 39

0 = x² - 9.5·x + 19.5

From an hint obtained by plotting the function, we have;

0 = (x - 3)·(x - 6.5)

We check for the local maximum as follows;

dV/dx = d(2·x³ - 19·x² + 39·x)/dx = 0

6·x² - 38·x + 39 = 0

x² - 19/3·x + 6.5 = 0

x = (19/3 ±√((19/3)² - 4 × 1 × 6.5))/2

∴ x = 1.288, or 5.045

At x = 1.288, we have;

V = 2·1.288³ - 19·1.288² + 39·1.288 ≈ 22.99

V ≈ 22.99 in.³

When x = 5.045, we have;

V = 2·5.045³ - 19·5.045² + 39·5.045≈ -30.023

Therefore;

V > 0 for 0 < x < 3 and V < 0 for 3 < x < 6.5

The values of x for which the model makes sense and V ≥ 0 is 0 ≤ x ≤ 3.

The values of x for which the model makes sense are 13/2 and 3

The equation that represents the volume of the box is given as:

[tex]V =2x\³ -19x\² +39x[/tex]

Factor out x from the above equation

[tex]V =x(2x^2 -19x +39)[/tex]

Expand the above equation, as follows

[tex]V =x(2x^2 -6x - 13x +39)[/tex]

Factorize the above equation

[tex]V =x(2x(x -3) - 13(x -3))[/tex]

Factor out x - 3

[tex]V =x(2x -13)(x -3)[/tex]

Equate to 0

[tex]x(2x -13)(x -3) = 0[/tex]

Solve for x

[tex]x = 0[/tex] or [tex]x = 13/2[/tex] or [tex]x = 3[/tex]

The value of x cannot be 0.

Hence, the values of x for which the model makes sense are 13/2 and 3

y=5/2 .   *the question doesn't specify a y-intercept for the perpendicular line so just leave it as if it passes through 0.

Step-by-step explanation:

First, you isolate y to put the line in slope intercept form. Then, you take the slope and find the reciprocal(-5/2) then flip the sign giving you a slope of 5/2.

Mixed number: [tex]7\frac{6}{10}[/tex]

Improper fraction: [tex]\frac{76}{10}[/tex]

Step-by-step explanation:

[tex]7.6[/tex] can be written in the form [tex]\frac{76}{10}[/tex]. This is an improper fraction since the numerator is greater than the denominator.

The mixed number is [tex]7\frac{6}{10}[/tex] since [tex]10[/tex] goes into [tex]76[/tex] seven whole times with a remainder of [tex]6[/tex].

Answer:

10 points

Step-by-step explanation:

Points scored in each of the first 3 quarter = x

Total points scored in the first 3 quarter = x + x + x

= 3x

Points scored in the fourth quarter = 14

Total points scored = 44 point

Total points scored = Total points scored in the first 3 quarter + Points scored in the fourth quarter

44 = 3x + 14

Subtract 14 from both sides

44 = 3x + 14

44 - 14 = 3x + 14 - 14

30 = 3x

Divide both sides by 3

x = 30/3

= 10

x = 10 points

Points scored in each of the first 3 quarter = x = 10 points
