Which is a solution to the linear inequality 2x-3y>6
A. (3,0)
B. (-3,1)
C. (3,-1)

Answers

Answer 1

Answer:

C ( 3,-1) is a solution

Step-by-step explanation:

2x-3y>6

Let x = 3

2(3) -3y >6

6 - 3y>6

Subtract 6

-3y >0

Divide by -3

-3y/-3 < 0/-3

y < 0

If x = 3 y must be less than 0

C ( 3,-1) is a solution

Answer 2
The answer is C.

Plug it into the equation.

2(3) - 3(-1) > 6

Simplify.

6 + 3 > 6

9 > 6

Since this is true, this is the answer.

True or False?

Answers

Answer:

[tex]\boxed{\sf{FALSE}}[/tex][tex]\boxed{\sf{x\leq 15}}[/tex]

Step-by-step explanation:

Isolate the term of x from one side of the equation.

x-5≤10

First, add by 5 from both sides.

[tex]\sf{x-5+5\leq10+5}[/tex]

Solve.

Add the numbers from left to right.

[tex]\sf{10+5=15}[/tex]

[tex]\Longrightarrow: \boxed{\sf{x\leq 15}}[/tex]

Therefore, the solution is x≤15, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.

hello!

Let's solve this inequality.

First, we should add 5 to both sides:-

x≤10+5

x≤15

Remember, the "≤" sign means "less than or equal to"

So is x=6 a solution to the inequality x≤15? Will this solution make the inequality true?

Yes.

m6=129

Step-by-step explanation:

m1=51

m2 =39

m3=90

m4=51

m5=17

m6=129

The total of all angles in a triangle is 180.

For angle 1 we are given an angle of 39 and the other of 90 so the angle 1 is 51.

Also we are provided angle 1 plus 2 is 90 so the angle 2 is 90-51 which is 39.

Angle 4 can be found by 180-90- 39which is 51.

If 3 is 180- 39-51= 90

Angle 5 can be found by 180-90-34-39 =17

Angle 6 is 180-35-17=129

Answer:

y = -5x - 3

Step-by-step explanation:

To answer this the slope must be clculated first

slope equation:

[tex]\frac{y2-y1}{x2-x1}[/tex]

these variables symbolize ordered pairs, and the best part is that you can use any two ordered pairs for this example we can use (-5, 10) and (-3,0)

we'll call the first ordered pair 1 so x1 = -5 and y1 = 10.

the next odered pair is 2 so x2 = -3 and y2 = 0.

With this information layed out we can solve:

[tex]\frac{0-10}{-3-(-5)}[/tex]

0 - 10 = -10

-3 - (-5) = 2 --- remember negatives cancel each other out to make a positive

[tex]\frac{-10}{2}[/tex] = -5

the slope of the line is -5. Now the next thing to note is that one of the ordered pair (-3,0) is a y intercept. It's time to introduce the equatione of a line:

y = mx+b

There are other equations that can be used for a line but with the info given this equation best suits the data.

m = slope

y and x = are the ordered pair you can input into the equation to slove

b = the y intercept

So the equation would be:

y = -5x - 3

For finding the surface area of the entire cylinder, we need to use the proper formula which is [tex]SA = 2 \pi r h + 2 \pi r^2[/tex]. Since the problem already gives us the radius and height, we can easily plug in the numbers. The equation should now look like this: [tex]SA = 2 * 3.14*3*6 +2*3.14*3^2[/tex].

After multiplying and adding all the numbers in the formula, we get a surface area of 169.56 yards squared.

For the lateral surface area, we can just subtract the [tex]2 \pi r^2[/tex] part from the formula.

[tex]SA = 2 * 3.14* 3 *6[/tex], which is 113.04 yards squared for the lateral surface area.

It’s asking for total and lateral surface area.
Total = 2pi x r x h + 2pi x r to the power of 2
Lateral = 2pi x r x h
For total it would be 2 x pi x 3 x 6 + 2 x pi x 3 to the power of 2 ( pi = 3.14)
For lateral it would be 2 x pi x 3 x 6
Just put that in the calculator and you’ll get your answer
Btw r = radius and radios is the half of something so if you see the line on the base go all the way you know it’s the diameter and not the radius so you would have to divide it by 2 to get your radius.
Total = 131.88
Lateral = 113.04

A plane travels at a constant speed. It takes 6 hours to travel 3,360 miles. What is the plane’s speed in miles per hour? At this rate, how many miles can it travel in 10 hours?

Answers

The planes speed would be 560 miles/hour.
If you divide 3360 by 6 = 560
In 10 hours the plane would travel 5,600 miles.
560 x 10 = 5600
First to find the planes speed in miles per hour,
Divide 3360 by 6 which gives you 560.
Then, to find for 10 hours, you would multiply 560 by 10 which gives you 5600.
The plane can travel 5600 miles in 10 hours.

m1=35

m2=77

m3=49

m4=77

m5=62

m6=28

Step-by-step explanation:

The required angles are ∠ 1 = 35°, ∠ 2 = 77°, ∠ 3 = 49°, ∠ 4 = 77°, ∠ 5 = 62° and ∠ 6 = 28°

What are angles?

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes.

Given is a figure, we need to find the marked angles from it,

∠ 2 + 103° = 180° [linear pair]

∠ 2 = 77°

∠ 1 + ∠ 2 + 68° = 180° [angle sum property of a triangle]

∠ 1 = 35°

∠ 4 = ∠ 2 [vertically opposite angles]

∠ 4 = 77°

Now,

∠ 3 + 41° = 90° [angles in a right triangle]

∠ 3 = 49°

∠ 6 = 180° - (∠ 3+103°)

∠ 6 = 28°

∠ 5 = 90°-∠ 6

∠ 5 = 62°

Hence, the required angles are ∠ 1 = 35°, ∠ 2 = 77°, ∠ 3 = 49°, ∠ 4 = 77°, ∠ 5 = 62° and ∠ 6 = 28°
