Answer:
Step-by-step explanation:
If there needs to be 4 teachers per 21 students, you would divide the total amount of students by 21 and multiply that answer by 4. SO...:
84 ÷ 21 = 4 groups of 21 students.
4 groups × 4 teachers = 16
*** Answer***
16 TEACHERS

Answer:
g(f(x)) = 36[tex]x^{4}[/tex] - 54x² + 12
Step-by-step explanation:
Substitute x = f(x) into g(x) , that is
g(6x²)
= (6x²)² - 9(6x²) + 12
= 36[tex]x^{4}[/tex] - 54x² + 12
Simplify each using the distributive property and/or combining like terms:
1.) 4x - 91X + 8)
2.) 6x-4 +2x +9

Solve for the variable. Show all work. |6x| - 8 = -8
Answer:
x = 0
Step-by-step explanation:
|6x| - 8 = -8
Add 8 to each side
|6x| - 8+8 = -8+8
|6x| = 0
Removing the absolute value
6x = 0
Divide by 6
6x/6 = 0/6
x = 0

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 14x - 2. The value of x is 7. The value of the expression at x =7 will be calculated as:-
E = 14x - 2
E = 14 x 7 - 2
E = 96
Therefore, the value of the expression at x = 7 will be 96.

Identify square root of 3 as either rational or irrational, and approximate to the tenths place.
Answer:
Irrational
[tex]\sqrt{3}[/tex] = approx. 1.7
Step-by-step explanation:
The square root of 3 is irrational, because 3 is not a perfect square.
For example, 4 is a perfect square, so the square root (2) will be rational.
The square root of 3 is 1.73205080757,
and we can round this to 1.7 for the tenths place
The formula a = m − n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon. Group of answer choices n=a+m n=m−a n = a − m n = −m − a
Answer: Option B.
Step-by-step explanation:
The given formula is
[tex]a=m-n[/tex]
where,
a = actual cost of an item.
m = Original price
n = Amount of coupon
We need to solve the formula for the amount of the coupon (n).
In means, we need to isolate n in the given formula.
We have,
[tex]a=m-n[/tex]
Subtract m form both sides.
[tex]a-m=m-n-m[/tex]
[tex]a-m=-n[/tex]
Multiply both sides by -1.
[tex]-(a-m)=n[/tex]
[tex]-(a)-(-m)=n[/tex]
[tex]-a+m=n[/tex]
So, [tex]n=m-a[/tex].
Therefore, the correct option is B.
Solve the following equation for x? -5(1-5x)+5(-8x-2=-4X-8x
Answer:
-5
Step-by-step explanation:
-5(1-5x)+5(-8x-2) = -4x-8x
-5+25x-40x-10 = -12x
-15-15x = -12x
-15 = -12x + 15x
-15 = 3x
x = -15 ÷ 3
∴x = -5

What is the inverse relation of the function whose equation
is y = 3x – 2?
oy = x
o y = 3x + 2
o y = 2x - 3
x + 2
y =
3
Answer:
The inverse of the function is;
x = (y + 2)/3
Step-by-step explanation:
Here in this question, we shall be calculating the inverse of a function.
The function is;
y = 3x - 2
Firstly, let w = x;
y = 3w -2
y + 2 = 3w
w = (y + 2)/3
Now replace w by x
x = (y + 2)/3
This is the inverse of the function

Answer:
To simplify the given radical form, we must recall some properties of exponents as shown below. 1. 1/x⁻ⁿ = xⁿ 2. x¹/² = √x Now, going back to 1/x⁻³/⁶, we have 1/x⁻³/⁶ = x³/⁶ x³/⁶ = x¹/² x¹/² = √x Using the properties provided, we have a simplified form of √x. Answer: √x

Miki has 104 nickels and 88 dimes. She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes. What is the largest number of groups she can have?
Given :
Miki has 104 nickels and 88 dimes.
She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.
To Find :
Largest number of groups she can have .
Solution :
In the given question we need to find the largest number of groups she can have i.e we have to find the LCM of 104 and 88 .
Now , factorizing both of them , we get :
[tex]104=1\times 2\times 2\times 2\times 13[/tex]
[tex]88=1\times 2\times 2\times 2\times 11[/tex]
Form above , we can say that common factors are :
[tex]HCF=2\times 2\times 2=8[/tex]
Therefore , the largest number of groups she can have is 8 .
Hence , this is the required solution .

Find the midpoint of a segment with the given endpoints.
W(-2,5), X(3,-17) =
Answer:
The answer is
[tex]( \frac{1}{2} \: , \: - 6)[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
W(-2,5) and X(3,-17)
The midpoint is
[tex]M =( \frac{ - 2 + 3}{2} , \: \frac{5 - 17}{2} ) \\ = ( \frac{1}{2} \: , \: - \frac{12 }{2} )[/tex]We have the final answer as
[tex]( \frac{1}{2} \: , \: - 6)[/tex]Hope this helps you
