A number x is greater than 7 graph line

Mathematics

1 answer:

Anettt [7]2 years ago

5 0

I graphed this line below.

Start with an open dot on 7.

The reason we use an open dot is because x

does not equal 7, it is only greater than 7.

So from your open dot, draw an arrow to the right

to represent all numbers greater than 7.

Finally, state your answer in set notation if possible.

It is read as {x: x > 7}.

Answer:

x= 12/5

Step-by-step explanation:

Also, if you mean simplify, it can no longer be simplified, so it would just be

1/4x-3/5.

Hope this helps!!

Plz let me no if I'm wrong.

A random sample of 4000 U.S. citizens yielded 2150 who are in favor of outlawing cheesing. Find the point estimate for estimatin

Darina [25.2K]

Answer:

0.5375

Step-by-step explanation:

The point estimate of proportion of all Americans who are in favor of outlawing cheese can be computed as

p=x/n

Here. x is the number of favorable outcomes and n is sample size.

We are given that x=2150 and n=4000, So,

p=2150/4000

p=0.5375.

Thus, the point estimate of proportion of all Americans who are in favor of outlawing cheese is 0.5375.

<h3>One less than the product of four and a number is 11. What is that number ?</h3>

Answer: The number is 3

Step-by-step explanation:

We will call X the number, then 4X - 1 = 11

4X = 11 + 1 =12

X = 12/4 =3

This is the number = 3

Can you explain how to do this math problem?

d1i1m1o1n [39]

Since the problem is 2x^2-5xy-y^3 we first have to plug in what the x and y stands for, once you do that your problem should look like this:

2(-3)^2- 5(-3)(-2)- (-2)^3

Now take the parentheses away and when you do that your signs change.

2x3^2-5x(-3)x(-2)-(-2)^3

do it again with -5x(-3)x(-2)

2x3^2-30-(-2)^3

now do this with (-2)^3

2x3^2-30-(-8)

Now evaluate the power

3^2 becomes 9

2x9-30-(-8)

then change -(-8) to a positive since two negatives make a positive

2x9-30+8

Now multiply the numbers 2x9

18-30+8

Then do 18-30 which equals -12 then add 8

Now you are left with your answer:

Hope this helps! :3

The force F of attraction between two bodies varies jointly as the weights of the two bodies and inversely as the square of the

crimeas [40]

We have that F is proportional to m1. Hence, we have that F=m1*c when we change the first mass. We also have that F=m2*c when we only change the 2nd mass. Since F scales inversely with the square of the distance, we have that $F= \frac{c}{d^2}$ . Combining all of the facts above, we get that F=c* $\frac{m_1 m_2}{d^2}$ where c is a constant.
