Which Number Line Represents The Solution Set For The Inequality - 2x2 4? -10 -8 6 -4 -20 2 4 6 8 10

Answers

Answer 1

Answer:

Option (2)

Step-by-step explanation:

Given inequality is,

[tex]-\frac{1}{2}x\geq 4[/tex]

⇒ [tex]\frac{1}{2}x\leq -4[/tex]

⇒ x ≤ -8

When we plot this inequality on a number line,

An arrow starting with a solid point from x = -8 and arrow directing towards negative numbers will represent the given inequality.

Option (2) will be the answer.

Answer 2

Answer:

[tex] - \frac{1}{2} x \geqslant 4 \\ - x \geqslant 2 \times 4 \\ - x \geqslant 8 \\ \boxed{\ x \leqslant - 8}[/tex]

x→{-∞,-8]

Number line :---

Arrow which represents solid sphere directed from (-8) moving towards left (-∞) will be the answer

2nd one is the right answer.

Hello there!

The answer would be x=15

4 3/8 ÷ 1 3/8 = answer asap and correct

Answers

Answer:

3 2/11

Step-by-step explanation:

4 3/8 = 4 + 3/8 = 32/8 + 3/8 = 35/8

1 3/8 = 1 + 3/8 = 8/8 + 3/8 = 11/8

then:

4 3/8 ÷ 1 3/8 = (35/8) / (11/8) = 35/11

35/11 = 33/11 + 2/11 = 3 2/11

Answer:

[tex]4 \frac{3}{8} \div 1 \frac{3}{8} = \frac{35}{8} \div \frac{11}{8} = \frac{35}{8} \times \frac{8}{11} = \boxed{\frac{35}{11} }[/tex]

35/11 is the right answer.

Write and equati9n of a l8ne that passes through (1,-2) and is perpendicular to -4x+7y=21

Answers

Given:

A line passes through (1,-2) and is perpendicular to [tex]-4x+7y=21[/tex].

To find:

The equation of that line.

Solution:

We have, equation of perpendicular line.

[tex]-4x+7y=21[/tex]

Slope of this line is

[tex]m_1=-\dfrac{\text{Coefficient of x}}{\text{Coefficient of y}}[/tex]

[tex]m_1=-\dfrac{-4}{7}[/tex]

[tex]m_1=\dfrac{4}{7}[/tex]

Product of slope of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]\dfrac{4}{7}\times m_2=-1[/tex]

[tex]m_2=-\dfrac{7}{4}[/tex]

Now, slope of required line is [tex]-\dfrac{7}{4}[/tex] and it passes through (1,-2). So, the equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope.

[tex]y-(-2)=-\dfrac{7}{4}(x-1)[/tex]

[tex]4(y+2)=-7(x-1)[/tex]

[tex]4y+8=-7x+7[/tex]

[tex]4y+7x=7-8[/tex]

[tex]7x+4y=-1[/tex]

Therefore, the equation of required line is [tex]7x+4y=-1[/tex].

What is the x-value at which the graphs of y = x2 – 2x + 1 and y = x2 + 2x – 7 inter-
sect?

Answers

Answer:

x = 2

Step-by-step explanation:

Both equations are equal to y, so they're also equal to each other.  We then set them equal to each other:

x^2 - 2x + 1  =  x^2 + 2x - 7

We now do algebra to isolate x.  Subtract 1 from both sides.

x^2 - 2x  =  x^2 + 2x - 8

Subtract 2x from both sides.

x^2 - 4x  =  x^2 - 8

Subtract x^2 from both sides.

-4x = -8

Divide both sides by -4.

x = 2

Find the slope of the line that passes through the following points. (-5, -2) (5, 2)
2/5

10/4
2 1/2

Answers

Answer:

The slope is 2/5

Step-by-step explanation:

Calculating the Slope of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the points (-5, -2) (5, 2). Let's compute the slope:

[tex]\displaystyle m=\frac{2-(-2)}{5-(-5)}[/tex]

[tex]\displaystyle m=\frac{4}{10}[/tex]

Simplifying:

[tex]\displaystyle m=\frac{2}{5}[/tex]

The slope is 2/5

Graph y=-2x+5y=−2x+5y, equals, minus, 2, x, plus, 5.

Answers

Answer:

Please check the graph of the function y=-2x+5 attached below.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Given the function

[tex]y=-2x+5[/tex]

comparing with the slope-intercept form of the line equation

The slope m = -2

The y-intercept b = 5

The graph of y=-2x+5 is attached below.

Determining the y-intercept from the graph

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 5

Thus, the y-intercept b = 5

Please check the graph of the function y=-2x+5 attached below.

y=2x+9

Answers

..............................

x=-9/2

x=-3/4

Answer:

x = 6

y = 21

Step-by-step explanation:

y = 2x + 9

y = 4x - 3

2x + 9 = 4x - 3

• Get the like-terms together:

9 + 3 = 4x - 2x

12 = 2x

• Divide 2x and 12 by 2 (to get x by itself):

12 ÷ 2 = 2x ÷ 2

6 = x OR x = 6

• To find the value of y, we have to substitute x into one of the equations (it doesn't matter which equation you plug x into, if the value of x is correct, both will equal the same number):

y = 2(6) + 9

y = 12 + 9

y = 21

y = 4(6) - 3

y = 24 - 3

y = 21

vertical angles (pairs of angles on opposite sides of an intersection) are equivalent

supplementary angles (angles found next to each other on a line) add up to 180 degrees

opposite interior angles are equivalent

And I don't remember the name of this kind of angle, but angle 1 and 10 are equivalent because they are found on the same "location"

using these rules you can find all missing angles.
