Step-by-step explanation:
4k - 3 = 2k + 5 Given
4k - 3 -2k = 2k + 5 - 2k Addition (added -2k to both sides )
4k - 2k - 3 = 2k - 2k + 5 Commutative (changed the order of the terms)
2k - 3 = 0 + 5 Addition/ Identity
2k - 3 = 5 Addition
2k - 3 + 3 = 5 + 3 Addition (added 3 to both sides)
2k + 0 = 8 Addition
2k = 8 Identity

Work out the area of a rectangle with base,b= 32mm and perimeter,P= 78mm.
Answer:
224
Step-by-step explanation:
b = 32, h = 7 is the solution to P = 78. Hence, 7*32 = 224 is the answer
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

Which equation represents a line parallel to 3x − 8y = 12?
The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4 so option (A) is correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given equation,
3x − 8y = 12
3x - 12 = 8y
y = (3/8)x - 12/8
By comparing y = mx + c
Slope m = 3/8
The parallel lines have the same slope thus y = (3/8)x - 4 will have the same slope of 3/8 so it will be parallel.
Hence "The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4".

Step-by-step explanation:
An auto shop charges a customer an equal amount for each new tire purchased plus an additional fee for an oil change.
The function C(t) = 87t +32 represents the total cost, C, of getting an oil change and purchasing t, tires.
What does the number 87 represent in the function?
A The slope and the cost per tire purchased.
B The slope and the fee for an oil change.
The y-intercept and the cost per tire purchased.
The y-intercept and the fee for an oil change.
The cost per unit of the auto shop function is the slope of the function
87 represents the slope and the cost per tire purchased
The function is given as:
[tex]\mathbf{C(t) = 87t + 32}[/tex]
A linear function is represented as:
[tex]\mathbf{C(t) = mt + b}[/tex]
Where:
m represents the slope or the unit rate.
So, by comparison:
[tex]\mathbf{m = 87}[/tex]
This means that 87 represents the slope and the cost per tire purchased

Step-by-step explanation:
The function g(x) is a transformation of the quadratic parent function, f(x) =
x2. What function is g(x)?
a. g(x) = 1/2x^2
b. g(x) = -2x^2
c. g(x) = 2x^2
d. g(x) = -1/2x^2
The function g(x) is a transformation (flipped upside down and horizontally stretched) of the quadratic parent function, f(x) = x2. g(x) = -0.5x².
What is flipping upside down?Flipping upside down, is found by taking the negative of the original function; that is, the rule for this transformation is −f (x).
Since, g(x) is an upside down function of f(x), g(x) = -f(x).
What is stretching a graph?If we multiply a function by a coefficient, the graph of the function will be stretched.
A function h(x) represents a horizontal compression of f(x) if h(x) = f(cx) and c > 1.
A function h(x) represents a horizontal stretch of f(x) if h(x) = f(cx) and 0 < c < 1.
Since, g(x) is clearly a stretched transformation of f(x), c < 1.
The possible function g(x) = -0.5x².

find x if the base angles of an isosceles triangle are 47 degrees and 3x+14
Answer:
Step-by-step explanation:
The value of x is 11.
Given,
The base angles of an isosceles triangle are 47 degrees and 3x+14 degrees.
We need to find x.
What is an isosceles triangle?An isosceles triangle is a triangle that has two equal sides and two equal angles.
The equal angles are the base angles.
Find x.
We have,
Base angles: 47 degrees and (3x + 14) degrees
Since base angles are equal in an isosceles triangle.
We have,
47 = 3x + 14
47 - 14 = 3x
33 = 3x
x = 33/3 = 11
x = 11
Thus the value of x is 11.
