Answer:

The third choice, [tex]x\leq -8[/tex]

Step-by-step explanation:

One way to do it is to substitute in the potential answers. I'll show you here.

Choice 1

[tex]2(-2)+3\leq (-2)-5[/tex]

[tex]-4+3\leq -2-5[/tex]

[tex]-1\leq -7[/tex]

We can see that this is false, so the answer cannot be choice 1.

Choice 2

[tex]2(2)+3\leq (2)-5[/tex]

[tex]4+3\leq 2- 5[/tex]

[tex]7\leq -3[/tex]

This is also false, so the answer cannot be choice 2.

Choice 3

[tex]2(- 8)+ 3\leq (-8)-5[/tex]

[tex]-16+3\leq -8-5[/tex]

[tex]-13\leq -13[/tex]

This is true. Let's see if choice 4 works.

Choice 4

[tex]2(8)+3\leq (8)-5[/tex]

[tex]16+3\leq 8-5[/tex]

[tex]19\leq 3[/tex]

This is not true. Therefore, 3 is correct.

Answer:  [tex]\frac{\sqrt{3}}{2}[/tex]

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

Explanation:

The symbol [tex]\theta[/tex] is the greek letter theta. It's often used in trigonometry for angles.

In this case, [tex]\theta = 30^{\circ}[/tex]

So,

[tex]\cos(\theta) = \cos(30^{\circ}) = \frac{\sqrt{3}}{2}[/tex]

You'll need to use a reference sheet or the unit circle to determine the value of cos(30). Or you could use a 30-60-90 triangle template.

When using the unit circle, look in the upper right quadrant (which is quadrant 1). The angle 30 degrees is in this quadrant. Locate the terminal point and note how [tex]\frac{\sqrt{3}}{2}[/tex] is the x coordinate of the terminal point. This is due to [tex]x = \cos(\theta)[/tex]

Side note: [tex]\frac{\sqrt{3}}{2} \approx 0.866025[/tex]

Answer:

26 Feet

Step-by-step explanation:

6 feet 6 inches x 4

Answer:

That would be about 26 feet.  

Step-by-step explanation:

Answer: y = 6; x = 12

Step-by-step explanation:

3x - 30 = y

Change this into an equation where x and y are in the same side.

3x - 30 = y

Subtract y from both sides

3x - y - 30 = 0

Add 30 to both sides

3x - y = 30

7y - 6 = 3x

Do the same thing I did to the first equation

7y - 6 = 3x

Subtract 3x from both sides

-3x + 7y - 6 = 0

Add 6 to both sides

-3x + 7y = 6

We can now use the system of elimination to find x and y.

3x - y = 30

-3x + 7y = 6

After adding both equations, you get:

6y = 36

Divide 6 from both sides

y = 6

Since we now know y, we can solve for x.

3x - 30 = y

Substitute y for 6

3x - 30 = 6

Add 30 to both sides

3x = 36

Divide both sides by 3

x = 12

Hope this helped!

Answer:

[tex]x = 12.y = 6[/tex]

Step-by-step explanation:

Restructuring

[3x - 30 = y

-3x - 6 =7y

[tex] \frac{ - 36}{ - 6} = \frac{ - 6y}{6} [/tex]

y=6

Sub 6 in equ II

7(6)-6=3x

Step-by-step explanation:

Equation of circle: (x + 2)² + (y - 2)² = r²

Radius of the circle is 3 (from -2 to 1).

Hence we have

(x + 2)² + (y - 2)² = 3² or (x + 2)² + (y - 2)² = 9.

Hello! (:

y=2x-5

This equation is written in slope-intercept form (y=mx+b)

Where

m is the slope of the line (2)

b is the y-intercept (5)

Hope it helps! Please ask if you have any query.

~An excited gal

[tex]MagicalNature[/tex]

The slope of the line y = 2x + 5 is 2 obtained by comparing it with slope intercept form y=mx+b, where m is slope.

The slope represents the rate at which the line is increasing or decreasing as you move along the x-axis.

The slope of a linear equation in the form y = mx + b is represented by "m."

In this case, "m" is 2, which means the slope of the line y = 2x + 5 is 2.

Since the slope is positive (2), it means that as x increases by 1 unit, y increases by 2 units, and as x decreases by 1 unit, y decreases by 2 units.

The slope of 2 indicates that the line is inclined, and it rises at a steady rate of 2 units for every 1 unit moved to the right along the x-axis.

Hence, slope of the line  y = 2x + 5 is 2.

Answer:

Part A: The percent discount on game is 20%.

Part B: Mario paid a total of $28.50 including sales tax.

Step-by-step explanation:

Given that:

Part A:

Original price of video game = $32.99

Discounted price = $26.39

Amount of discount = 32.99 - 26.39 = $6.60

Discount percent = [tex]\frac{Amount\ of\ discount}{Original\ price}*100[/tex]

Discount percent = [tex]\frac{6.60}{32.99}*100 = 0.20*100[/tex]

Discount percent = 20%

Part B:

Sales tax = 8% of discounted price

Amount of sales tax = [tex]\frac{8}{100}*26.39 = 0.08*26.39[/tex]

Amount of sales tax = $2.11

Total amount = $26.39 + $ 2.11 = $28.50

Hence,

Part A: The percent discount on game is 20%.

Part B: Mario paid a total of $28.50 including sales tax.

As table shows a proportional relationship between x and y then constant of proportionality are 20, 40, 0.2 and 20 respectively

In the first table, the constant of proportionality is 20 because each value of y is obtained by multiplying the corresponding value of x by 20.

In the second table, the constant of proportionality is 40 because each value of y is obtained by multiplying the corresponding value of x by 40.

In the third table, the constant of proportionality is 0.2 because each value of y is obtained by multiplying the corresponding value of x by 0.2.

In the fourth table, the constant of proportionality is 20 because each value of y is obtained by multiplying the corresponding value of x by 20.

Answer:

Please check explanations for answer

Step-by-step explanation:

Here, we want to show that the left hand side equals the right hand side

We can express the left hand side as:

sin A/ cos A * sec A/cosec A

kindly recall that;

sin A/cos A = tan A

Also;

sec A = 1/ cos A

cosec A = 1/ sin A

Thus, we have that ;

tan A * 1/cos A / 1 / sin A

= tan A * sin A/cos A

This is;

tan A * tan A = tan^2 A
