What is the slope of the line whose equation is 12=4x−6y?

Enter your answer in the box.

Answers

Slope= 2/3
Explanation- adding 6y on both sides and subtracting 12 on both sides of eq, 12 + 6y -12=4x+6y-6y-12
6y = 4x-12
Divide by 6 on both sides of eq, we get y=4/6 x -12/6
y=2/3 x-2

A football team has a net yardage of −28 1/3

yards on a series of plays. The team needs a net yardage of 30 yards to get a first down. How many yards do they have to get on their next play to get a first down?

Answers

Answer: 58 1/3 yards

Step-by-step explanation:

From the question, we are informed that a football team has a net yardage of −28 1/3 yards on a series of plays and that the team needs a net yardage of 30 yards to get a first down.

The number of yards that they have to get on their next play to get a first down would be calculated as:

= 30 - -28 1/3

Note that minus × minus = plus

= 30 + 28 1/3

= 58 1/3 yards

Brandi rolls a fair Six-sided Number cube flips a fair coin, and then rolls the number cube again. Which outcome is part of sample space?

Answers

Answer:

Options aren't given but explanation and answer is below:

Step-by-step explanation:

First action/trial  -  Rolling a fair dice (6-sided number cube)

Second action      -  Flipping a fair coin

Third action        -   Rolling a fair dice

In this experiment, all the equipment are fair. What this means is that there is no bias; every face of each equipment has an equal chance of emerging tops.

In your options, you should have three values per option.

The first would be the number resulting from the first throw of dice.

The second would be head or tail; which are the only two faces of a coin.

The third would be the number resulting from the second throw of dice.

So ONE of those options will be a part of the sample space, which is enlisted below:

Trial A:  {1, 2, 3, 4, 5, 6}

Trial B:   {Head, Tail}

Trial C:   {1, 2, 3, 4, 5, 6}

* If there's an option like {9, Tail, 2} it will be wrong, because it has an element "9" which does not fall within the prescribed sample space.

* Also, if we follow the order in which Brandi conducted this experiment, an option like {Head, 6, 5} will be wrong, since the elements are wrongly placed.

Answers

Answer:

D. 33 + 18

Step-by-step explanation:

Sum in mathematics is the same as addition or plus.

As such the sum of two or more numbers is the addition of these numbers or the result obtained when the plus sign is placed in between the given numbers.

Hence, the sum of 33 and 18 may be expressed as

Answer: C) ASA Theorem

================================================

Explanation:

Let's go through the answer choices one at a time.

A) The AA postulate is only used for similar triangles, and not congruent triangles. We need information about at least one pair of sides. Using the angles only isn't enough. We can rule out choice A.B) The HL postulate only applies to right triangles. These triangles are acute triangles, so we can rule out choice B.C) This is the answer as we can rule out choice D, so this is the only thing left. Also, if we know that angle A = angle A'' and angle B = angle B'', then we could use the ASA theorem to prove the triangles congruent.D) This is not a valid congruence theorem. This is because we could have ambiguous cases that arise and lead to confusion. Also, it is possible that if we know two sides and a non-included angle, then a triangle may not be able to be formed. It will depend on the angle and side values. Therefore, we can rule out choice D.

Michael's High School is selling tickets to its spring musical. On the first day of ticket sales the school sold 1 adult ticket and 3 student tickets for a total of $38. The second day of sales, the school sold 5 adult tickets and 1 student ticket for a total of $78

Write a system of equations to represent the number of tickets sold each day

Determine the price of an adult ticket and a student ticket

Answers

Answer:

adult ticket price: $14

student ticket price: $8

Step-by-step explanation:

x = adult ticket

y = student ticket

system equations:

[tex]x + 3y = 38 \\ 5x + y = 78[/tex]

elimination method:[tex]x + 3y = 38 |multiple \: by \: 1\\ 5x + y = 78|multiple \: by \: 3 \\ \\ x + 3y = 38 \\ 15x + 3y = 234 \\ subract \: them: \\ - 14x = - 196[/tex]

substitute:[tex] - 14x = - 196 \\ - x = \frac{ - 196}{14} \\ - x = - 14 \\ x = 14[/tex]

find the y using substitution method:

x+3y=38

14+3y=38

3y=24

y=24/3

y=8

so the price of an adult ticket is $14 and the price of student ticket is $3

Tim goes on a car journey.
for the first 15 minutes his average speed is 40 mph

he then stops for 25 minutes
he then completes the journey at an average speed of 45mph
the total journey time is 1 hour.
A) draw a distance time graph for his journey?
B) what is the average speed for the whole journey?

Answers

Answer:

See attached picture ;

25 miles / hour

Step-by-step explanation:

First phase :

Travel time = 15 minutes

Average speed = 40 mph

Distance covered = speed * time

Distance covered = 40 * (15/60) = 10 miles

Second phase :

25 minutes stop

Third phase :

Average speed = 40 mph

Distance covered = speed * time

Travel time = 60 - (25 + 15) = 20 minutes

Distance covered = 45 * (20/60) = 15 miles

Average speed for the journey :

Total distance / total time taken

= (10 miles + 15 miles) / 1 hour

= 25 miles / hour
