What does 3/4 mean in ordered pairs.

Answer:

x ≈ - 5.32, x ≈ 1.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2) x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{11}[/tex]

Then

x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )

x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )

Answer:

The graph is not a function.

Step-by-step explanation:

Using the "vertical line test" to attach a vertical line to each of the points on the graph, we will find that the vertical line that passes through (0,0) has ot one, but two points on it. Remember, if the vertical line passes through more than one points, the graph is not a function. As we know, the vertical line passes through two points, those being (0, -4) and (0, -3). So, we can conclude that the graph is not a function.

Answer:

60

Step-by-step explanation:

The whole thing is 180 so if you subtract 180 from 120 you get 60.

Answer:

60 degrees since a straight line is 180 degrees

Step-by-step explanation:

Since part of it is 120 degrees the other part must be 60 because 120 + 60 = 180

Answer:

The blank in the equation is 1.

x = 7 and the vertical angles measure out to 64 degrees.

Step-by-step explanation:

When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.

Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

Answer:

The image point of (-7, 1) after reflection across the y-axis is:

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-7, 1)

Let say the point is A(-7, 1).

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-7, 1) → A'(-(-7), 1) → A'(7, 1)

Therefore, the image point of (-7, 1) after reflection across the y-axis is:

Area : 27.5

Perimeter : 20

Step-by-step explanation:

All sides of a regular pentagon have the same length

1 side = 4

4x5 = 20 = Perimeter

Pentagon area formula :

1/4(sqrt(5(5+2sqrt(5)))x)

Plug x in (side length)

Answer:

Step-by-step explanation:

Assuming that 23 is the first term

4823

25th term of arithmetic sequence is 4,823

Given arithmetic sequence:

23, 223, 423, 623,...

Find:

25th term of arithmetic sequence

Computation:

First term a = 23

Common difference d = A2 - A1

Common difference d = 223 - 23

Common difference d = 200

Number of term n = 25

So,

An = a + (n - 1)d

A25 = 23 + (25 - 1)(200)

A25 = 23 + (24)(200)

A25 = 23 + 4,800

A25 = 4,823

Answer:

96°

Step-by-step explanation:

Ratio of angles :

3 : 4 : 8

Sum of angles in a triangle = 180°

The value of the largest angle = angle with the largest ratio

This is the value of the angle with ratio 8

Sum of ratio : (3 + 4 + 8) = 15

Hence,

(8 / 15) * 180°

(8 * 180°) / 15

1440 / 15

= 96°
