what is the domain of f

Answer:

For the first one, C is the correct answer.

For the second one, C, B, and D are correct.

Step-by-step explanation:

Hi,

For the first one, you know y = x + 3 so you can just plug that into the second equation. Here's what I mean...

3x + y = 19

Plug in x + 3 for y since you know y = x + 3...

3x + (x + 3) = 19

Solve...

4x + 3 = 19

Subtract 3 on both sides...

4x = 16

Divide by 4 on both sides...

x = 4

Now, plug in 4 in the first equation.

y = x + 3

We know x = 4...

y = 4 + 3

y = 7

We know the solution is (4,7)

For the second one...

Since the two lines never intersect (cross) then there is no solution. They are parallel to each other (meaning they're going in the same direction just don't cross) and any system that doesn't have a solution will almost always have the same slope.

Hope this helps. Let me know if you have any questions :)

Answer:

x=66

Step-by-step explanation:

Hey There

So if you didn't know the exterior angle is equal to the sum of two opposite interior angles (38 and x)

so to find x we subtract 38 from 180

104-38=66

so x = 66

Answer:

52 degrees.

Step-by-step explanation:

When you look above you see 104, so divide this by 2 and get 52.

Answer:

15.1°

Step-by-step explanation:

In ΔGHI, the measure of ∠I=90°, GH = 96 feet, and IG = 25 feet. Find the measure of ∠H to the nearest tenth of a degree.

We solve using sine rule

GH/sin I = lG/ sin H

96/sin 90 = 25/sin H

Cross Multiply

sin 90 × 25 = sin H × 96

sin H => sin 90 × 25/96

H => arc sin( sin 90 × 25/96)

H => 15.09479°

Approximately ∠H = 15.1°

Answer:

1 is biased, 2 isn't, 3 is biased, 4 isnt

Step-by-step explanation:

If you ask a question to people in a group who are already clearly for a certain topic then it is biased. For survey to not be biased, the people need to be chosen at random. Ask students what their favorite class is, or ask flight attendants where their favorite destination to travel to is. Dont use a group who has any relation to the survey at hand. Asking band students about funding for band is biased, as well as asking people who are at a SOCCER GAME what their favorite sport is.

The area of the triangle △ABC is 12 square units.

The question is incomplete. The actual question is

Triangle ABC is symmetric about the y-axis. Point A is located at (-3,0), and AB is the longest side of ABC. If the perimeter of ABC is 16, what is the area?

Symmetrical forms or figures are things that can have a line drawn through them so that the representations on both sides of the line mirror each other.

As could be seen in the figure the triangle  △ABC is symmetric along the y-axis. Hence, the side AC and BC must be of the same length let us call it 'a'. Also, the coordinate of B must be (3,0) because (3,0) is the reflection of (-3,0) corresponding to the y-axis.

And, the length of AB=6 units because the distance between (-3,0) and (3,0) is 6 units.

Now, the perimeter of the triangle is 16 units. Therefore,

2a+6=16

⇒a=(16-6)/2

⇒a=5 units.

Hence, we have an isosceles triangle △ABC we can find the height 'h' of the triangle using the Pythagoras theorem. Consider the triangle  △ACE
then we have that

the height of the right triangle  △ACE= h

the base of the right triangle  △ACE= 3 units

the hypotenuse of the right triangle  △ACE= a = 5 units.

Hence, by Pythagoras' theorem

h²+3²=5²

⇒h²=25-9=16

⇒h=4 (we choose the positive value of h because length is always positive)

Hence, the area of the triangle △ABC is

(1/2)×base×height

=(1/2)×AB×CE

=(1/2)×6×4 unit²

=12 unit²

Hence, the area of the triangle △ABC is 12 square units.

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

The percentages total 100%, so the missing percentage is

  100% - 60% = 40%

The numbers on the number lines are proportional, so now you can write ...

  ?/100% = 28/40% . . . . . . ? total students

Multiplying by 100% gives ...

 ? = 28/0.4 = 70 . . . . . total students

Then the 60% portion of students can be found two ways:

  60% × 70 = 42 students . . . . 60% of students

  70 -28 = 42 students

Answer:

The solution set is;

y < 3

This means the values of the real numbers set that are less than 3 in value

Step-by-step explanation:

Here, we want to get the solution set of the inequality

what we have to do is to get the value of y

We have this as;

15y < 36 + 9

15y < 45

y < 45/15

y < 3
