A rational numbers is any number that can be turned into a fraction/ratio. (Ex. 8, 0.75, 1/3). An irrational number is anything that can't be turned into a fraction/ratio. (Ex. Pi, square root of 2). Radicals and rational exponents are related because radicals can be converted into rational exponents.
Answer:
Any number that can be written as a fraction with integers is called a rational number. An irrational number is a number that cannot be expressed as a fraction for any integers. Radicals are related because for irrational numbers they cannot be simplified under the radical and you use a radical on the exponent to cancel it out, hope this helps!

[tex]\pink{\bigstar}[/tex] Amount of apple juice Will added [tex]\large\leadsto\boxed{\tt\purple{1 \frac{5}{12}}}[/tex]
• Given:-Will puts 1/4 cup of grape juice in a cup.He added apple juice and then he had 1⅔ cup of juice in the cup.• To Find:-How much apple juice Will added to the cup?• Solution:-➪ Amount of grape juice Will added = 1/4
➪ Amount of juice in total after adding the apple juice = 1⅔
Therefore, it is clear that the amount of apple juice Will added to the cup will be the difference in total amount of juice and amount of grape juice.
Hence,
➪ [tex]\sf 1 \frac{2}{3} - \dfrac{1}{4}[/tex]
➪ [tex]\sf \dfrac{5}{3} - \dfrac{1}{4}[/tex]
• Taking an L.CM:-

can someone help me with this?
Answer:
15
Step-by-step explanation:
3a+b=54
3a+9=54
54-9=45
45 ÷ 3= 15
3 × 15 - 9=54
45 + 9=54
Negative x + 6y = 16 and 8x - 6y = -2 which statements about the system of equations are true check all that are apply the x variable will be eliminating when adding the system of equations and the y variable will be limited when adding the system of equations or the sum of the system equations is negative 8X = 14 or x = 2 or y = 3 or there's only one solution to the system equations
Answer:
y variable will be elimited when adding the system of equations
x = 2 or y = 3
Step-by-step explanation:
- x + 6y = 16
8x - 6y = -2
Add both equations
(-x + 8x) + {6y + (-6y)} = 16 + (-2)
7x + 6y - 6y = 16 - 2
7x + 0 = 14
7x = 14
x = 14/7
x = 2
- x + 6y = 16
- 2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
the x variable will be eliminating when adding the system of equations and the
y variable will be elimited when adding the system of equations
or the sum of the system equations is negative 8X = 14 or
x = 2 or y = 3
or there's only one solution to the system equations

Select all expressions that are equivalent to 16x − 12 − 24x + 4 by showing your work & explain your reasoning. 1)40x - 16 2)4 - 12 - 4x + (- 4x) 3) 8x - 8 4)-8 (r + 1)
Answer:
4 - 12 - 4x + (- 4x)
-8 (x + 1)
Step-by-step explanation:
16x - 12 - 24x + 4
16x - 24x - 12 + 4
-8x - 8
1)40x - 16 = not equivalent
2)4 - 12 - 4x + (- 4x)
4 - 12 - 4x - 4x
-8 - 8x = - 8x - 8 (equivalent)
3) 8x - 8 (not equivalent)
4)-8 (x + 1) = - 8x - 8 (equivalent)

Kira ,Charlie , and Miguel have a total of $105 in their wallets . Kira has $9 less than Miguel. Charlie has 4 times what Miguel has . How much does each have ?
Let the money with Miguel be x.
Then :
Money with Kira = x - 9
Money with Charlie = 4x
Total money in their wallet = $105
This can be written in an equation as :
[tex] = \tt \: x + x - 9 + 4x = 105[/tex]
[tex] = \tt2x + 4x - 9 = 105[/tex]
[tex] = \tt 6x - 9 = 105[/tex]
[tex] = \tt6x = 105 + 9[/tex]
[tex] = \tt6x = 114[/tex]
[tex] = \tt x = \frac{114}{6} [/tex]
[tex] = \tt x = 19[/tex]
Which means :
Money with Miguel = $19
Money with Kira :
= 19 - 9
Thus, Kira has $10 in her wallet.
Money with Charlie :
= 4 × 19
= 76
Thus, Charlie has $76 in his wallet.
Therefore, Money with Kira = $10Money with Charlie = $76Money with Miguel = $19Answer:
Let the money with Miguel be x.
Then :
Money with Kira = x - 9
Money with Charlie = 4x
Total money in their wallet = $105
This can be written in an equation as :
= \tt \: x + x - 9 + 4x = 105=x+x−9+4x=105
= \tt2x + 4x - 9 = 105=2x+4x−9=105
= \tt 6x - 9 = 105=6x−9=105
= \tt6x = 105 + 9=6x=105+9
= \tt6x = 114=6x=114
= \tt x = \frac{114}{6}=x=
6
114
= \tt x = 19=x=19
Which means :
Money with Miguel = $19
Money with Kira :
= 19 - 9
Thus, Kira has $10 in her wallet.
Money with Charlie :
= 4 × 19
= 76
Thus, Charlie has $76 in his wallet.
Therefore,
Money with Kira = $10
Money with Charlie = $76
Money with Miguel = $19

This is domain, as it is the complete set of values. Range would be the difference between the highest and the lowest value (5-1)
Subtract the rational expression 1/x^2-x-6 - x/x+2.
Answer:
Step-by-step explanation:
x² - x -6 = x² + 2x - 3x - 3*2
=x(x + 2) - 3(x + 2)
= (x + 2 )(x - 3)
[tex]\frac{1}{x^{2}-x-6}+\frac{x}{x+2}=\frac{1}{(x +2 )(x - 3)}-\frac{x}{x + 2}\\[/tex]
[tex]= \frac{1}{(x+2)(x-3)}-\frac{x(x-3)}{(x+2)(x-3)}\\\\=\frac{1-x(x-3)}{(x+2)(x-3)}\\\\=\frac{1-x^{2}+3x}{(x+2)(x-3)}\\\\[/tex]

Answer:
Range: 1 > x > 3
Step-by-step explanation:
We are given then function;
y = x³ - 6x² + 9x + 5
dy/dx = 3x² - 12x + 9
We want to find the range of values of x for which dy/dx > 0
Thus;
3x² - 12x + 9 > 0
Using quadratic formula, we have;
x = 1 and x = 3
Let's define the range;
try x = 0
3(0²) - 12(0) + 9 = 9
This is more than 0, so it is part of the solution.
Let's try x = 4
3(4²) - 12(4) + 9 = 9
This is more than 0 so it is part of the solution
Let's try x = 2
3(2²) - 12(2) + 9 = -3
This is less than 9 and so it's not part of the solution.
Thus the range of values of x for which dy/dx > 0 is;
1 > x > 3

How many tacos will he sell?
Answer:
Step-by-step explanation:
x + y =35
3x + 2y = 90
-3x - 3y = -105
3x + 2y = 90
-y = -15
y = 15 tacos
x + 15 = 35
x = 20 sandwiches
20 sandwiches = x
15 tacos = y

Nancy bought a mobile phone marked at 720$ at a discount of 20 percent and she had to pay 5 percent tax. If Nancy had to put 20 percent of what she had to pay including tax as a deposit, how much money did she have to pay for the deposit?
Answer:
$120.96
Step-by-step explanation:
If there is a 20% discount, she would pay 80% of the price
o.80 x $720 = $576
If there is a tax of 5%, the price she pays increases by 5%
1.05 x 576 = 604.80
If she pays 20% deposit, she would pay
0.2 x 604.80 = $120.96

We can see that the graph is shaded to the left of -1. This means that x is all values less than (<) -1, so C and D are incorrect. Additionally, since the dot is not filled in, this means that x is not going to be equal to -1, which eliminates B. This leaves A, x < -1.
