10. Determine if the equation x - y = 1 defines y as a function of x.
Answer:
No.
Step-by-step explanation:
First solve for y:-
x - y^4 = 1
y^4 = x - 1
y = +/- (x - 1)^(1/4)
This is a one-to-many relation . For a given value of y there 2 values of x.
So this is NOT a function.

Step-by-step explanation:
∠ L = 180° - (60 + 60)° = 180° - 120° = 60° [ sum of angles in Δ = 180° ]
Since the 3 angles are 60° , then the triangle is equilateral with the 3 sides being congruent.
Then
5x - 3 = 4 ( add 3 to both sides )
5x = 7 ( divide both sides by 5 )
x = [tex]\frac{7}{5}[/tex] = 1.4
and
2y + 6 = 4 ( subtract 6 from both sides )
2y = - 2 ( divide both sides by 2 )
y = - 1
Place the following steps in order to describe how to solve the following equation: 2(2x+3)-2=52(2x+3)−2=5
Answer:
frist parentheses then subtract
The solution of equation 2(2x+3)-2 = 52(2x+3)−2 = 5 is x = -29/20.
What is PEMDAS?The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
The given equation:
2(2x+3)-2 = 52(2x+3)−2 = 5
Simplifying,
2(2x+3)-2 = 52(2x+3)−2 - 5
Using PEMDAS,
first, we solve the parentheses
4x+6 - 2 = 104x + 156 - 2 - 5
4x+4 = 104x + 149
104x - 4x = 4 - 149
100x = -145
x = -145/100
x = -29/20
Therefore, the value of x is -29/20.

Given PQ = 24
PS = 19
PR = 42
TQ = 10
m<PQR = 106°
m<QSR = 49°
m<PRS = 35°
find m<QRS, m<PQS, m<RPS and m<PSQ
The shape PQRS is a parallelogram
The measure of angle QRS is 70 degreesThe measure of angle PQS is 53 degreesThe measure of angle RPS is 35 degreesThe measure of angle PSQ is 53 degreesThe given parameters are:
[tex]\mathbf{\angle PQR = 106}[/tex]
[tex]\mathbf{\angle QSR = 49}[/tex]
[tex]\mathbf{\angle PRS = 35}[/tex]
(a) Find QRS
This is calculated as:
[tex]\mathbf{\angle QRS = 2 \times \angle PRS }[/tex]
So, we have:
[tex]\mathbf{\angle QRS = 2 \times 35}[/tex]
[tex]\mathbf{\angle QRS = 70}[/tex]
Hence, the measure of angle QRS is 70 degrees
(b) Find PQS
This is calculated as:
[tex]\mathbf{\angle PQS = \frac 12 \times \angle PQR }[/tex]
So, we have:
[tex]\mathbf{\angle PQS = \frac 12 \times 106}[/tex]
[tex]\mathbf{\angle PQS = 53}[/tex]
Hence, the measure of angle PQS is 53 degrees
(c) Find RPS
This is calculated as:
[tex]\mathbf{\angle RPS = \angle PRQ }[/tex]
Where:
[tex]\mathbf{\angle PRQ = \angle PRS = 35}[/tex]
So, we have:
[tex]\mathbf{\angle RPS = 35}[/tex]
Hence, the measure of angle RPS is 35 degrees
(d) Find PSQ
This is calculated as:
[tex]\mathbf{\angle PSQ =\frac 12 \times \angle PQR }[/tex]
Where:
[tex]\mathbf{\angle PSQ =\frac 12 \times \angle 106}[/tex]
So, we have:
[tex]\mathbf{\angle PSQ =53}[/tex]
Hence, the measure of angle PSQ is 53 degrees

What are the the values of x and y that satisfy this equation?
( x + yi ) + ( 4 + 9i ) = 9 - 4i
A. x = 9 and y = -4
B. x = 5 and y = 13
C. x = 5 and y = -13
D. x = -9 and y = 4
Answer: C. x = 5 and y = -13
I hope this helps.
The value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given equation is,
( x + yi ) + ( 4 + 9i ) = 9 - 4i
The points are x= 5 and y = -13,
( x + yi ) + ( 4 + 9i ) = 9 - 4i
( 5 -13i ) + ( 4 + 9i ) = 9 - 4i
5 + 4 -13i+9i = 9-4i
9-4i = 9 - 4i
Therefore, the value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.

The volume of this cone is 540π. Work out the height,h, of the cone, radius=9cm
Answer:
h = 20
Step-by-step explanation:
540π = 1/3 . h . π . 9^2
get rid of π
540 = 1/3 . h . 9^2
multiply by 3 to get rid of 1/3
3 . 540 = h . 9^2
1620 = h . 81
divide by 81
1620/81 = h
20 = h
