Answer:

8 min

Step-by-step explanation:

Crew C =2

loser L =3

min 1 2C goes

min 1 1C comes

min 4 3L goes

min 1 1C comes

min 1 2C goes

total min 8

Step-by-step explanation:

(2/3 + 4/5) / (3/6)

= (10/15 + 12/15) * 2

= (22/15) * 2

= 44/15.

Answer:

the slope of a vertical line is undefined

Step-by-step explanation:

its undefined because it doesn't move horizontally. however if you had a horizontal line, the slope would be 0

Answer:

AC+BD = 78

Step-by-step explanation:

Given that,

AB = 15, AD = 36

We need to find the value of AC+BD.

[tex]BD^2=AB^2+AD^2[/tex]

We can find BD.

[tex]BD^2=15^2+36^2\\\\BD=39[/tex]

According to figure,

BC should be equal to AD and AB should be equal to CD.

AC+BD = BD+BD

= 2BD

= 2 × 39

= 78

So, the value of AC+BD is equal to 78.

Answer:

72

Step-by-step explanation:

Multiply 72 by .75 and you get 54

Step-by-step explanation:

By Factor Theorem, we have:

(x - 1)(x - 2)(x - 3)(x + 3)

= (x² - 3x + 2)(x² - 9)

= x⁴ - 3x³ - 7x² + 27x - 18.

Answer

C but then again i might be wrong

Answer:

C) (6,8) Is your answer

Step-by-step explanation:

point b(2,5)

remember

(x,y)

x=moves left or right

y moves up or down

so 4 units left and 3 units up

if you go left or down u subtract if you go right or up you add

so

(2,5)+(4,3)

=

(6,8)

Hope this helps!

[tex]t = \frac{3 - 4p}{p + 2}[/tex]

Step-by-step explanation:

Given

[tex]P = \frac{3 - 2t}{4 + t}[/tex]

Required

Make t the subject

[tex]P = \frac{3 - 2t}{4 + t}[/tex]

Cross Multiply

Answer:

1) angle 1 is 55 degrees

2) angle 2 is 55 degrees

3) angle 3 is 70 degrees

4) angles 1 and 2 are vertical

Step-by-step explanation:

1) angle 1 = 180 - (85 + 40)

2) angle 2 has the same measure of angle 1

3) angle 3 is 180 - (55 + 55)

4) angles 1 and 2 are vertical and congruent

Answer:

80%

Step-by-step explanation:

First, add all the numbers up to get 76.

Then, add the dogs, hamsters, and fish to get 61.

Finally, divide 61 by 76 to get 0.80

So, 80% of students had dogs, hamsters and fish.

Variation tax = 0,25

Step-by-step explanation:

Direct variation is the name we gave to the rate of change of a first degree function.

A first degree generic function is:

y = f(x) = ax + b

Now observe the question's function:

- x + 4y = -2

4y = x - 2

y = 1/4x - 2/4

y = f(x) = 0,25x - 0,5

0,25 is our constant variation, because any number that x assume will be multiplied by 0,25.

b) The y-intercept represent the initial distance before she started hiking

7. The domain of the function is 0 ≤ c ≤ ∞

8. The correct option is;

b. all real numbers from 2.6 to 13"

9. Please find attached the required graph of the function created with Microsoft Excel

Step-by-step explanation:

6. From the given graph, we have;

The coordinate of the y-intercept = (0, 4)

The y-intercept represent the initial distance before she started hiking

7. The given function that models the number of cans Luis will have after his purchase is f(c) = 24·c + 5

The domain of the function is the possible values of "c", which is 0 ≤ c ≤ ∞

∴ The domain of the function = 0 ≤ c ≤ ∞

8. The number of hours Roger plays video games, t is 2 ≤ t ≤ 5

The number of games Roger plays on average within an hour = 2.6 games

The function f(t) = 2.6·t gives the number of games Roger plays in "t" hours

Therefore, we have;

The range = f(2) ≤ f(t) ≤ f(5) = 2.6 × 2 ≤ f(t) ≤ 2.6 × 5 = 5.2 ≤ f(t) ≤ 13

The range of the function = 5.2 ≤ f(t) ≤ 13

The correct option is "b" " all real numbers from 2.6 to 13"

9. Please find the required graph of the function [tex]f(x) = -\left | x - 2 \right | + 3[/tex], created with Microsoft Excel.

Answer:

k = -111.34

Step-by-step explanation:

In this question, you will solve for k.

Solve:

k/3.8 + 57.6 = 28.3

Subtract 57.6 from both sides.

k/3.8 = -29.3

To get "k" by itself, multiply both sides by 3.8 to eliminate the fraction.

k = -111.34

-111.34 is the value of "k".

Answer: Slope = 8.000/2.000 = 4.000

x-intercept = 14/-4 = 7/-2 = -3.50000

y-intercept = 14/1 = 14.00000

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(4*x+14)=0

Equation of a Straight Line

1.1 Solve y-4x-14 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-4x-14 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 14/1 so this line "cuts" the y axis at y=14.00000

y-intercept = 14/1 = 14.00000

Calculate the X-Intercept :

When y = 0 the value of x is 7/-2 Our line therefore "cuts" the x axis at x=-3.50000

x-intercept = 14/-4 = 7/-2 = -3.50000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 14.000 and for x=2.000, the value of y is 22.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 22.000 - 14.000 = 8.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 8.000/2.000 = 4.000

Geometric figure: Straight Line

Slope = 8.000/2.000 = 4.000

x-intercept = 14/-4 = 7/-2 = -3.50000

y-intercept = 14/1 = 14.00000

Answer:

In order from top to bottom, the tiles are,

x=5+4i

x=-4+5i

x=4-5i

Step-by-step explanation:

All of these solutions are complex numbers, which means the equation has imaginary roots. Complex numbers are written in the form of a+bi, where a is a real number and bi represents the imaginary number. For quadratic equations, complex roots are often also complex conjugates. This means that the solution is x=a+bi, so to find the other conjugate simply switch the sign. For example, if x=5-4i is a solution, so is x=5+4i.
