Which of the following statements says that a number is between -3 and 3?
Ix) = 3
Ix<3
O x > 3
Answer:
The inequality that represents this condition would be:
-3 < x < 3Step-by-step explanation:
Let x be the number between -3 and 3
Since x is between -3 and 3, so we do not have to include the integer -3 and 3 in the interval.
In inequality:
The symbol '>' is used to represent 'greater than'.The symbol '<' is used to represent 'less than'.Since the number 'x' is between -3 and 3. It means the number must be greater than -3 and less than 3.
Thus, the inequality that represents this condition would be:
-3 < x < 3The graph of the line number involving the solution -3 < x < 3 is also attached below.
Therefore, we conclude that:
[tex]-3<x<3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-3<x<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-3,\:3\right)\end{bmatrix}[/tex]

Answer:
solve for 6x+8
Answer:
x = 3
Step-by-step explanation:
Since ∠ P and ∠ S are congruent then the triangle is isosceles and
PT = TS , substitute values
7x + 4 = 5x + 10 ( subtract 5x from both sides )
2x + 4 = 10 ( subtract 4 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3

Answer:
Step-by-step explanation:
3x + 5y = 7
Since that is our original form, let's convert it so that we can find the slope:
5y = -3x + 7
y = -3/5 x + y
From here, we use the point-slope equation and then convert that into slope-intercept form:
y - y1 = m(x - x1)
y - 6 = 5/3(x - 0)
y - 6 = 5/3x

A big box retailer has one order for 9 plants and 6 bushes with a cost of $390. There is a second order for 7 plants and 8 bushes with a
cost of $400.
Which system of equations can be used to determine the price of a plant, p, and the price of a bush, b?
9p +6b = 390
7p + 8b = 400
9p + 8b = 390
7p + 6b = 400
7p + 8b = 390
9p + 6b = 400
7p +95 = 390
6p+8b = 400

Here you go( I dont feel like taking a screen shot- sorry)

Very helpful for k12 students, and hope this helps! sorry I am late.

On which triangle can the law of cosines be used to find the length of an unknown side? Law of cosines: a2 = b2 + c2 – 2bccos(A)
Explanation:
You would use this law under two conditions:
One angle and two edges defined, while trying to solve for the third edgeALL three edges definedHence, you have your answer.
* Just make sure to use the inverse function towards the end, or elce you will throw your answer off!
_______________________________________________
Now, you would use the Law of Sines under three conditions:
Two angles and one edge defined, while trying to solve for the second edgeOne angle and two edges defined, while trying to solve for the second angleALL three angles defined [of which does not occur very often, but it all refers back to the first bullet]* I HIGHLY suggest you keep note of all of this significant information. You will need it going into the future.

Oscar lends his brother $125.00 and charges him 5% interest. How much will Oscar's brother pay back for the loan?
use either the multiples method or the prime factors method to find the least common multiple of 24 and 16.
The prime factorization of 16: 16 = 2 ⋅ 2 ⋅ 2 ⋅ 2 = 24.
The prime factorization of 24: 24 = 2 ⋅ 2 ⋅ 2 ⋅ 3 = 23 ⋅ 3.
Both 16 and 24 have 23 ( 8 ) in common, so we can remove it from one of the numbers, leaving 24 and 3 . There are no more numbers in common, so the lowest common multiple is 24 ⋅ 3 = 48.
while working at the school store, john sold a jacket for $40.00 and notebooks for $1.50 each.If he collected $92.50, how many notebooks did he sell?
Answer:
35 Notebooks
Step-by-step explanation:
$1.50x35=52.5
$52.5+$40=$92.5
or $92.50 - 40=$52.5
35x1.5=52.5
Answer:
35 notebooks
Step-by-step explanation:
let notebook as be 'x'
here, $40.00+x($1.50)=$92.50
x($1.50)=$92.50-$40.00
x($1.50)=$52.50
x=$52.50/$1.50
x=35
