The rate of change between a and b is -5, and between x and x + h is also -5.
How to find the rates of change?
For a function f(x) the formula for the rate of change on an interval [a, b] is:
( f(b) - f(a))/(b - a)
so if the function is f(x) = -5x - 8, the average rate of change will be:
( -5b - 8 + 5b + 8)/(b - a) = 5*(a - b)/(b - a) = -5
c) Now we want to use the interval [x, x + h], we will get:
( -5*(x + h) - 8 + 5*x + 8)/(x + h - x)
= (-5h)/h = -5
Again, the rate is -5

What is Percentage?Percentage, a relative value indicating hundredth parts of any quantity.
Given that ,
Mike wants to buy a new suit. The suit he likes is on sale for 30% off it’s original price. Her parents agree to pay for 50$ of the cost.
the original cost of the bike is 150$.
We need to find how much has to pay her own.
Now firstly let us calculate what is the 30% of 150
We need to convert 30% to decimal by dividing with hundred
30/100=0.3
Now multiply 0.3 with 150
0.3×150=$45
Hence the off value is $45
Now subtract $45 from $150 we get
$150-$45=$105.
Siera parents will pay $50.
$105-$50
We get $55.
Hence Sierra has to pay $55 of her own money to get the bike.

Emily is standing 24 feet away from a light pole. The distance between Emily to a point of tangency on the pole is 12 feet. What is the radius of the light pole?Note : In the figure distance between Emily and the point of tangency is marked as 24 ft instead of 12.
From the given figure,

BC = Radius of the pole
AC = Distance between Emily and the pole.
ABC is a right angled triangle at B.

Quadrilateral ABCD is rotated 90 degrees about the orgin. What are the coordinates of the quadrilateral A'B'C'D?
The coordinates of the object image are;
A {5,5}
B{5,1}

D{1,5}
The rule for rotation of a point {x,y} through 90 degrees about the orgin, is that the object coordinates {x,y} change to image coordinates { y,-x}. This means the coordinates shift positions and the y coordinate acquires a negative sign. So in this case;
A {5,5}------- A' { 5,-5}

C{2,1} ---------C' {1,-2}
D{1,5} ---------D' { 5,-1}

The value of x that will make the line f parallel to line g is 6.
The theorem that allows you to prove line f is parallel to line g is corresponding line theorem.
How to find angles when parallel lines is cut by transversal?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.
The theorem that prove the line f is parallel to line g will make the two angles equal.
15x + 9 = 21x - 27
f and g will be parallel and cut by the transversal line h when
15x + 9 = 21x - 27
15x - 21x = -27 - 9
- 6x = -36
x = -36 / -6
x = 6
Therefore, corresponding angle theorem prove line f is parallel to line g and the value of x is 6 to make line f and g parallel.

Solve for x. 2x + 3 = 3 - (4x + 12)
For the equation, 2x + 3 = 3 - (4x + 12), the value for x is -2.
Linear Equation: An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.
The given equation is 2x + 3 = 3 - (4x + 12)
We have :
2x + 3 = 3 - (4x + 12)
Opening the brackets as a 1st step,
2x +3 = 3 - 4x -12
Keeping all the variable terms on one side,
2x +4x = 3 - 12 - 3
Adding the variables and nonvariables, we get:
6x = -12
Now, Dividing both sides by 6,
[tex]x = \frac{-12}{6} = -2[/tex]
Hence, the value of x is -2.

A rectangle has two dimensions—length and width—because it is a two-dimensional shape. The rectangle's longer side is its length, and its shorter side is its width. A quadrilateral with all of its angles equal, or right angles, is a rectangle. In addition to having all equal angles, a square also has all equal sides.
