please help!!!​

Answers

Answer 1

Answer:

4x-2y=0

Step-by-step explanation:

Ok

so you need to subtract

(3x+2y=22)-(-x+4y=22)

Use distributive property and take away parenthesis

3x+2y=22+x-4y=-22

----------------------------

3x+2y=22

x-4y=-22

------------------------------

4x-2y=0

Answer 2

Answer:

( [tex]\frac{22}{7}[/tex] , [tex]\frac{44}{7}[/tex] )

Step-by-step explanation:

3x + 2y = 22 ....... (1)

- x+ 4y = 22 ........ (2)

3 × (2) + (1)

(3x - 3x) + (2y + 12y) = 22 + 66 ( variable "x" is eliminated )

14y = 88

y = [tex]\frac{44}{7}[/tex]

- x + 4( [tex]\frac{44}{7}[/tex] ) = 22

x = [tex]\frac{176}{7}[/tex] - [tex]\frac{154}{7}[/tex] = [tex]\frac{22}{7}[/tex]

( [tex]\frac{22}{7}[/tex] , [tex]\frac{44}{7}[/tex] )

Use differences to find a pattern in the sequence.

Answers

The 8th term of the pattern is 254.

Here the sequence is 9, 16, 29, 50, 81, 124, 181

By using differences we have :

 9,    16      29      50      81      124     181

  |___|  |___| |___|  |___|  |___|  |____|

                ↓          ↓         ↓          ↓

               +2        +2       +2        +2

Therefore to find the 8th value of the pattern

We will add 2 in 14

14 + 2 = 16

Now 16 should be added to 57

57 + 16 = 73

Now we will add 73 to the 181 we get

181 + 73 = 254

Therefore the 8th term of the pattern is 254 by using the difference.

Equation: 190 = 6 + 23p

Answer: p = 8

Step-by-step explanation:

So first we have a total of $190 and regardless of how many people go, parking is going to cost $6 so that amount will be reduced from the total money they have for the amusement park. The rest left will go towards the tickets. That means the amount they have is $190-$6 = $184. 23 x the number of tickets = $184. You need to divide the 184 by 23 to get the number of tickets. Which is p in this situation. Therefore the answer for p would be 8. For the equation, you have 190 = 6 + 23p. Therefore those two is our answers.

Which complex number has a distance of StartRoot 17 EndRoot from the origin on the complex plane?
2 + 15i
17 + i
20 – 3i
4 – i

Answers

Answer:

4 - i

Step-by-step explanation:

Intuitively, the answer will be 4 - i, as the other numbers are too big to have a square as small as 17i.  Also, we know that  i will not be in the end result, which means that we should have a negative in the result as well.

To test this, we can simply treat 4 and -i as the sides of a right triangle and find the hypotenuse:

[tex]d = \sqrt{4^2 + (-i)^2} \\d = \sqrt{16 + 1}\\d = \sqrt{17}[/tex]

We need to find the value of x.

[tex]\dfrac{19,432}{x}=48[/tex]

Cross multiplying both sides,

So, the value of x is 404.83.

Answer:

x = 400

Step-by-step explanation:

To find x, you first need to subtract the remainder from 19,432.

That equals 19,200. Then you need to do 19,200 divided by 48.

The measures of the angles of a quadrilateral are 3:8:7:2 find the measure of each angle

Answers

Answer:

Angle 1=  54°

Angle 2= 144°

Angle 3 = 126°

Angle 4 = 36°

Step-by-step explanation:

We are given measures of the angles of a quadrilateral are 3:8:7:2

Let the common ratio = x

The angles will be:

Angle 1= 3x,

Angle 2= 8x,

Angle 3 =7x

Angle 4 =2x

We know that sum of all angles of quadrilateral = 360°

We can write as: [tex]3x+8x+7x+2x=360[/tex]

Solving to find x,

[tex]3x+8x+7x+2x=360\\20x=360\\x=\frac{360}{20}\\x=18[/tex]

We get value of x = 18

Now, finding angles:

Angle 1= 3x = 3(18) = 54°

Angle 2= 8x = 8(18) = 144°

Angle 3 =7x = 7(18) = 126°

Angle 4 =2x = 2(18) = 36°

maria walks 22 feet, then goes another 40 feet on a path that makes a 70 degree angle with the path she was on. how far is she, in feet, from her starting location?

Answers

Answer:

132 feet

Step-by-step explanation:

22+60+70

The distance of the Maria from her starting location is 109.9 feet.

What is trigonometry?

Right angle triangles are the focus of the mathematical field of trigonometry. Calculations involving specific functions of angles are the focus of trigonometry.

In trigonometry, the following six functions are frequently used: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (cosec)

Let's call the distance Maria is from her starting location "x".

The 70 degree angle forms a right triangle with the distance Maria walked initially (22 feet) and the distance she is from her starting location (x). We can use the trigonometric function tangent to find x:

tan(70°) = x/40

Multiplying both sides by 40, we get:

x = 40 tan(70°)

Using a calculator, we find that tan(70°) is approximately 2.7475. Multiplying by 40, we get:

x = 109.9

So Maria is approximately 109.9 feet from her starting location.
