Jennifer’s bank account is modeled by the following equation where x equals the number of weeks and
f(x) equals the total balance.
f(x) = 12x + 45
william's bank account balances after weekly deposits are showing in the following table.
Jennifer claims that her bank account is growing at a greater rate of change than William’s bank account. Is Jennifer correct? Justify your reasoning.
Jennifer is correct her bank account is growing at a greater rate of change than William’s bank account. Because, initially Jennifer has $45 in her account and it grows every week.
Given that, Jennifer’s bank account is modeled by the equation f(x)=12x+45.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Substitute x=0, 1, 2, 3, 4, we get y=12x+45
Now,
When x=0, y=12(0)+45=45
When x=1, y=12(1)+45=57
When x=2, y=12(2)+45=69
When x=3, y=12(3)+45=81
When x=4, y=12(4)+45=103
Jennifer is correct her bank account is growing at a greater rate of change than William’s bank account. Because, initially Jennifer has $45 in her account and it grows every week.

Step-by-step explanation:
On the graph, two right triangles have the line as the hypotenuse. In this task, you will use these triangles to show that the slope between points E and A is the same as the slope between points A and C.
Q1:
Which angles of the triangles measure 90°?
Q2: To show that the other two angle measurements in each triangle are equal, you can use parallel lines cut by a transversal. Which two pairs of line segments formed by triangle sides are parallel, and what is the transversal for each pair?
Answer:
1.The 6th one
2. The pairs can be (6, 8)
Step-by-step explanation:
We know that, the Slope is always given as [tex]\bold{\dfrac{Rise}{Run}}[/tex], where the rise is the vertical height of the slope and run is the horizontal length of the slope.
For Δ ADE,
rise = DE = 4 units,
run = DA = 6 units,
[tex]\bold{slope = \dfrac{Rise}{Run} =\dfrac{4}{6} = \dfrac{2}{3}}[/tex]
For Δ ABC,
rise = AB = 2 units,
run = BC = 3 units,
[tex]\bold{slope = \dfrac{Rise}{Run} = \dfrac{2}{3}}[/tex],
Thus, the slope of line EA and AC is equal.
We know in a Right Angle Triangle the side opposite to the right angle is the longest side and it is known as hypotenuse.
As already mentioned in the question " two right triangles have the line as the hypotenuse", which means line EA and line AC are already said as the hypotenuse of the triangles. therefore, the angle opposite to them is the right angle in the triangles.
1.)
In ΔABC, the hypotenuse is the line AC, therefore, the right angle is the opposite angle which is ∠ABC.
Similarly, In ΔEDA, the hypotenuse is the line EA, therefore, the right angle is the opposite angle which is ∠EDA.
2.)
Parallel lines are those lines that always maintain the same distance between them and will never meet. whereas, a transversal is a line that crosses two or more parallel lines. As shown in the image below,
Here, there are two pairs of parallel lines cut by a transversal
Pair I: line ED and line AB are a pair of parallel lines, can be easily seen if both the lines are extended, while AD (or x-axis), line BC(only if extended), and line EC are the transverses between them.
Pair II: line DA and line BC are a pair of parallel lines, can be easily seen if both the lines are extended, while AB (or y-axis), line ED(only if extended), and line EC are the transverses between them.

The entrance to an accessibility ramp is at ground level.
The first section of the ramp covers a horizontal distance of 18 feet and rises to a landing 1.5 feet above the ground.
The second section of the ramp begins at the landing. It rises at a slope of \frac{1}{18}
and covers another 9 feet of horizontal distance to reach the door.
NOTE: Sketch not drawn to scale.
Answer the questions to compare the sections of the ramp.
1. What is the slope of the ramp from the ground to the landing? Write your answer as a fraction with a whole-number numerator and denominator.
Answer:
Step-by-step explanation:
slope = "rise over run" = 1.5/18 = 3/36 = 1/12 for the 1st section to the landing
slope is the change in height, the vertical change, divided by the change in horizontal distance
2nd section has slope 1/18 and covers 9 feet. That means it rises 1/2 foot
slope = 1/18 = (1/2)/9
the door is 2 feet higher than the ground level, 1.5 + .5 = 2 feet change vertically
