I WILL MARK AS BRAINLIEST! Choose The inequality that represents the statement and then graph if on The line provided. Lacey has flown at least 120 miles.
Answer: Choice b) [tex]x \ge 120[/tex]
The graph will involve a closed filled in circle at 120, with shading to the right.
See the diagram below.
============================================
Explanation:
The phrasing "at least" means "that amount or more".
Saying "at least 120" is the same as "120 or more".
Therefore, x = 120 is the smallest x can be. That's why we go for [tex]x \ge 120[/tex] which says that either x = 120 or x > 120.
Visually, we'll plot a closed filled in circle at 120 on the number line. The shading will aim to the right to indicate all values larger than 120. The closed/filled in circle is to represent we include 120 (as opposed to an open circle where we exclude it).
Due to the fact that your teacher gave you a blank number line, the placement of 120 doesn't really matter.

Express each number as a product of its prime numbers.
1. 245
2. 510
3. 250
4. 1,089
5. 4,725
6. 900
18. 27,000
Answer:
Numbers expressed as a product of prime factors are as follows:-1. 245 = 5 × 7 × 7
2. 510 = 2 × 3 × 5 × 17
3. 250 = 2 × 5 × 5 × 5
4. 1089 = 3 × 3 × 11 × 11
5. 4725 = 3 × 3 × 3 × 5 × 5 × 7
6. 900 = 2 × 2 × 3 × 3 × 5 × 5
18. 27000 = 2 × 2 × 2 × 3 × 3 × 3 × 5 × 5 × 5

2a = -2
a = -1

A car factory made 8 cars with a sunroof and 18 cars without a sunroof what is the ratio of the number of cars without a sunroof to the total number of cars?
Answer:
No of cars without sunroof=18
Total no of cars=18+8=26
Now,the ratio of cars without sunroof to total no of cars=18÷26
= 9÷13

Explanation: You would need to evaluate & simplify the expression.
4 − (x + 2) < −3(x + 4)
Answer:
x<-7
Step-by-step explanation:
4 − (x + 2) < −3(x + 4)
4 − x - 2< −3x - 12
14 < - 2x
x<-7
Answer and Step-by-step explanation:
First, we need to solve both sides of the equation.
Distribute the negative to the x and the 2.
4 - x - 2 < -3(x + 4)
Distribute the -3 to the x and the 4.
4 - x - 2 < -3x - 12
Combine like terms.
2 - x < -3x - 12
Add 12 to both sides of the equation.
12 + 2 - x < -3x - 12 + 12
14 - x < -3x
Add x to both sides of the equation.
14 - x + x < -3x + x
14 < -2x
*Divide both sides of the equation by -2, and flip the sign.
-7 > x
-7 > x is the answer.
*How this works:
When we flip the sign, we really are just saving ourselves an extra step when dividing numbers (that are negative, only works when number is negative).
14 < -2x
If we were to add to x, and subtract 14, it will look like this:
2x < -14
Then when we divide by 2, we get:
x < -7
This is the same result, but it takes an extra step. Use this way if you forget why you need to flip the sign when dividing by a negative number.

3(x-5)+1=2+x Please put the work!!!!!!!!!!!!!!
Answer:
3(x-5)+1=2+x
3x-15+1=2+x
3x-x=2+15-1
2x=16
x=8
Answer:
x=8
Step-by-step explanation:
3(x-5)+1=2+x
Subtract 1 from both sides.
3(x-5)=1+x
Distribute the 3
3x-15=1+x
Add 15 to both sides.
3x=16+x
Subtract x from both sides.
2x=16
Divide both sides by 2.
x=8

use a, b, c, or d, also it's a multiple choice question
Answer:
a and c i think
Step-by-step explanation:
Use complete sentences to describe why √-1 ≠ -√1
Well let's say that to compare these two numbers, we have to start with the definition first.
Definition
[tex] \displaystyle \large{ {y}^{2} = x} \\ \displaystyle \large{ y = \pm \sqrt{x} }[/tex]
Looks like we can use any x-values right? Nope.
The value of x only applies to any positive real numbers for one reason.
As we know, any numbers time itself will result in positive. No matter the negative or positive.
Definition II
[tex] \displaystyle \large{ {a}^{2} = a \times a = |b| }[/tex]
Where b is the result from a×a. Let's see an example.
Examples
[tex] \displaystyle \large{ {2}^{2} = 2 \times 2 = 4} \\ \displaystyle \large{ {( - 2)}^{2} = ( - 2) \times ( - 2) = | - 4| = 4}[/tex]
So basically, their counterpart or opposite still gives same value.
Then you may have a question, where does √-1 come from?
It comes from this equation:
[tex] \displaystyle \large{ {y}^{2} = - 1}[/tex]
When we solve the quadratic equation in this like form, we square both sides to get rid of the square.
[tex] \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{ - 1} }[/tex]
Then where does plus-minus come from? It comes from one of Absolute Value propety.
Absolute Value Property I
[tex] \displaystyle \large{ \sqrt{ {x}^{2} } = |x| }[/tex]
Solving absolute value always gives the plus-minus. Therefore...
[tex] \displaystyle \large{ y = \pm \sqrt{ - 1} }[/tex]
Then we have the square root of -1 in negative and positive. But something is not right.
As I said, any numbers time itself of numbers squared will only result in positive. So how does the equation of y^2 = -1 make sense? Simple, it doesn't.
Because why would any numbers squared result in negative? Therefore, √-1 does not exist in a real number system.
Then we have another number which is -√1. This one is simple.
It is one of the solution from the equation y^2 = 1.
[tex] \displaystyle \large{ {y}^{2} = 1} \\ \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{1} } \\ \displaystyle \large{ y = \pm \sqrt{1} }[/tex]
We ignore the +√1 but focus on -√1 instead. Of course, we know that numbers squared itself will result in positive. Since 1 is positive then we can say that these solutions exist in real number.
Conclusion
So what is the different? The different between two numbers is that √-1 does not exist in a real number system since any squared numbers only result in positive while -√1 is one of the solution from y^2 = 1 and exists in a real number system.
Answer:
Therefore [tex]\sqrt{1} \neq -\sqrt{1}[/tex]
Step-by-step explanation:
[tex]\sqrt{-1} \\[/tex] cannot be calculated as no two identical numbers that are multiplid could give -1. However - [tex]\sqrt{1}[/tex] means -1 x [tex]\sqrt{1}[/tex] = -1 x 1 = -1 . Therefore [tex]\sqrt{1} \neq -\sqrt{1}[/tex]
400 written as a product of its prime factors is 2 x 2 x 2 x 2 x 5 x 5.
Write 800 as a product of its prime factors.
Answer: 2 x 2 x 2 x 2 x 2 x 5 x 5
Explanation:
We start with the string 2 x 2 x 2 x 2 x 5 x 5
Then we tack on a "2 x" up front, or at the very left, so that we double the result. This is because the jump from 400 to 800 is "times 2".
So we go from 2 x 2 x 2 x 2 x 5 x 5 to 2 x 2 x 2 x 2 x 2 x 5 x 5

I hope it helped U
stay safe stay happy
Answer:
1/2^2
Step-by-step explanation:
When you have a number to a negative power, you can rewrite it inverting it's fraction and changing the signal of the power. 2 can be wrote as a fraction like 2/1, so you have 2^-2, it's like 2^-2/1, so you invert the fraction and the signal of the power, and have 1/2^2

b. He cannot with the first but he can with with second. For the first, we have 0=x^2+3. Then subtract 4 from each side and get -3=x^2. This isn't possible in a theoretical term. For the second, you have 0=square root of x -2 or 2=square root of x. That means x is 4.

help me please
6(9 + 5x) = 54 +
Hi
to progress in math, you must : know by heart the rules and formulas then train.
rule : a ( b+c ) = a*b + a*c.
this propertie is call distributivity .
so we have : 6 ( 9+5X)
here : a = 6
b = 9
c = 5X
so 6 ( 9+5X) = ?
I let you have a shot. Ask in comments section if you are stuck. But try first !
Answer:
1) rearrange terms:
6(9 + 5x) = 54
6(5x + 9) = 54
2) Distribution :
6(5x + 9) = 54
30x + 54= 54
3) subtract 54 from both side:
30x + 54 = 54
30x + 54 - 54 = 54 - 54
4) Simplify: subtract the numbers
30x = 0
5) Divide both side of the equation by the same term:
30x = 0
30x√30 = 0√30
6) Simplify: cancel term that are in the both numerator and denominator
x = O√30
solution :
x = 0]

Answer:
box = 30
Step-by-step explanation:
You could set this up very formally as a proportion. It would look like this.
1/5 = 6/x
Now all you have to do is cross multiiply.
1*x = 5 * 6
x = 30
So the answer that goes in the box is 30
Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"
The answer is 6
6 * 5 = 30
