Inequalities with one variable are plotted on a number line, with the output representing the solution to the inequality. A number line is used to graph a linear inequality with only one variable. Two-dimensional graphs plot linear inequalities with two variables because the output gives the solution to both variables.
Answer:
x>3
Step-by-step explanation:
on a number line, an open circle indicates that the given value (3) isnt included and you would use < or >. a closed (filled in) means that the given value is included and u would use ≤ or ≥. the direction of the arrow (left of right) indicates if the values will be greater than or less than the value indicated by the circle (3). Here, the arrow is pointing right meaning that the values are getting larger until infinity starting at 3 (3 isnt included because of the open circle)

Step-by-step explanation:
We know that B is 90 because its a right angle, and in that triangle it has to add up to 180
So 180 - 90 = 90
90 ÷ 2 = 45
And thats a right angled triangle so it has a right angle and two equal angles.

I notice: All three squares are different sizes.
This proves: The Pythagorean Theorem is correct, and two smaller squares that form a right triangle are equal to the bigger square (the hypotenuse).
This proves it by having each smaller angle squared adding up to the bigger angle squared. Whenever these are equal, a right triangle is formed. One example is 5^2 (which is angle a squared) + 12^2 (which is angle b squared) = 13^2 (which is the hypotenuse, or c squared).
Answer:
Square C is comprised of the areas of squares A and B
It proves that this triangle is a right triangle
By adding the areas of two perfect squares, A and B, square C can only be the sum. This proves the Pythagorean Theorem to be true, as the ratios to the sides, and therefore the equation, will remain fixed in any scalene right triangle.

Answers
Hi Student!
Looking at this problem, it is pretty straight forward and we don't need to do much information gathering to help answer our question. The main point is that we just need to solve the equation also known as solving for the unknown variable.
Subtract 2 from both sides
[tex]6= 5x + 2[/tex][tex]6 - 2 = 5x + 2 - 2[/tex][tex]4 = 5x[/tex]Divide both sides by 5
[tex]\frac{4}{5} = \frac{5x}{5}[/tex][tex]\frac{4}{5} = x[/tex]Therefore, our final solution to this problem is that x is equal to 4/5 or we can convert this to a decimal to which we will then get 0.8.
Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis. Α = 0. 09 for a right-tailed test
Answers
From the z table the critical value corresponding to the level of significance level for a two-tailed test is z = 1.64.
How do form the hypotheses?There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test.
The hypothesis which we put against the null hypothesis is an alternate hypothesis.
The null hypothesis is the one that researchers try to disprove.
From the question, we are told that
The number of observations is greater than 50 i.e. n > 50
The level of significance is [tex]\alpha = 0.1[/tex]
Generally given that n > 30 then we will make use of the z table
So From the z table the critical value corresponding to the level of significance level for a two-tailed test is z = 1.64.

How to plot the point on the polar plane?
To plot a point (R, θ) on the polar plane. First, if R is positive the angle is measured from the positive x-axis, if R is negative, the angle is measured from the negative x-axis.
Because here R is 4, positive, the point will lie on the x-axis. Then, she needs to move it clockwise by an angle of (3/2)pi (a total of 3 quadrants) This means that the point will end up in the positive y-axis.
So what you need to write in each blank is:
1) positive x-axis.
2) negative x-axis.
3) positive y-axis.

Can someone help me with this?
Answers
Answer:
1. AE= 312
2. AC = 161
Step-by-step explanation:
Hey there!
In order to solve the first question, we need to think of possible "C" values
Then after finding the "C" value, we can then find the "A" and "E" values
So:
AC = 24 and CE = 13
What factors do 24 and 13 have in common?
Well, only 1 since 13 is a prime number]
So this means that C has to be 1
Now we know that A is 24 and E is 13
Now we have to multiply them together
24 x 13 is 312
So AE= 312
Now we go on to the second question
We can use the same strategy we used for number one
Instead of finding what C is, we need to find out what E is, since there is E in both of the statements
So:
CE = 7 and AE = 23
What common factors do these two numbers have?
Again, only 1, meaning that E can only be 1
Now we know that C is 7 and A is 23
Since we know this, we can multiply these two numbers together and get our final answer: 161
So AC = 161

how many times greater is 8.5x10^8 than 42x10^7 in scientific notation
Answers
Step-by-step explanation:
first, let's bring them to the same exponent of 10.
8.5 × 10⁸ is already scientific notation
42 × 10⁷ = 4.2 × 10⁸ (this is now scientific notation AND it is using the same exponent of 10)
so, how many times is the first one greater ?
(8.5 × 10⁸) / (4.2 × 10⁸) = 8.5 / 4.2 = 2.023809524...
so, the first number is 2.023809524... times greater than the second number.
maybe you made a typo ?
maybe the second number was actually 42.5 × 10⁷ ?
because then
42.5 × 10⁷ = 4.25 × 10⁸
and
8.5 / 4.25 = 2
so,
8.5 × 10⁸ is 2 times greater than 42.5 × 10⁷ or 4.25 × 10⁸.
