Answer:

<h2>"None of the statements are true".</h2>

Step-by-step explanation:

Let's examine each statement.

<h3>"The product of two numbers with the same sign is negative".</h3>

This statement is completely false, because they rule states that two number with the same sign as a positive product.

<h3>"The quotient of a positive dividend and a negative divisor is positive".</h3>

This statement is false, because they rule states that the quotient between number with different signs is negative.

<h3>"The quotient of 0 and a positive number is undefined".</h3>

This statement is also false, because the undefined quotient is when a number is divided by 0, not the opposite way. In this case, such quotient is just zero.

As you can observe, none of the statements are true.

Therefore, the right answer is "None of the statements are true".

Which of the following points lies in the solution set of the inequality y &gt; 3x +10?
shepuryov [24]

Since 3 is greater than -3, hence (-1, 3) lie in the solution set. Option C is correct

In order to determine the points that lie in the solution set of the inequality y > 3x +10, we will substitute the x-coordinate and see if <u>y is greater than the result.</u>

<u />

For the coordinate point (1, 10)

y > 3(1) +10

y > 13

Since 10 is not greater than 13, hence (1,10) does not lie in the solution set.

For the coordinate point (4, 20)

y > 3(4) +10

y > 22

Since 20 is not greater than 22, hence (4,20) does not lie in the solution set.

For the coordinate point (-1, 3)

y > 3(-1) +10

y > -7

Since 3 is greater than -3, hence (-1, 3) lie in the solution set.

If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual m
nlexa [21]

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

\angle1=2(17)+6\\\angle1=34+6\\\angle1=40

So, the actual measure of ∠1 = 40°

A cheetah can run at its top speed for about 25 seconds. Complete the table to represent a cheetah running at a constant speed.
AleksandrR [38]
X = 650 + 60t

The cheetah must arrive at the same place at the same time:

x = 90t

650 + 60t = 90t

30t = 650

t = 650/30 ≅ 21.7 s

It takes the cheetah a little more than 20 s running at 90 ft/s to reach the moving antelope, so assuming the antelope can maintain its speed of 60, it is safe.
