An equation for L, in terms of t, representing the amount Kadeesha owes her friend after t weeks is L = 8t + 120.
The table of values is as follows;
Number of Weeks Amount of Money Owed
0 $120
1 $128
2 $136
3 $144
How to write an equation to model this situation?In order to write a linear equation to describe this situation, we would assign variables to the amount of money that Kadeesha borrowed originally and the number of weeks respectively, and then translate the word problem into a linear equation as follows:
Let the variable L represent amount of money that Kadeesha owed.Let the variable t represent number of weeks.Since Kadeesha originally borrowed $120 and agreed to pay back her friend $8 per week, a linear equation which can be used to model the total amount of money that Kadeesha owed is given by;
L = 8t + 120
When t = 0, the value of L is given by;
L = 8(0) + 120
L = $120.
When t = 1, the value of L is given by;
L = 8(1) + 120
L = $128.
When t = 2, the value of L is given by;
L = 8(2) + 120
L = $136.
When t = 3, the value of L is given by;
L = 8(3) + 120
L = $144.

Step-by-step explanation:
Determine any horizontal or slant asymptotes of the rational function: f(X)= 3x^2-x/2x^2-1
The horizontal asymptote is y = 3/2, and the slant asymptote is y = x/2.
How to express the asymptoteWe need to compare the degrees of the numerator and denominator.
The degree of the numerator is 2, and the degree of the denominator is also 2. Therefore, the horizontal asymptote is given by the ratio of the leading coefficients, which is 3/2. The horizontal asymptote is y = 3/2
Furthermore, f(x) = 3/2 + x/(2x² - 1)
This expression shows that the function has a slant asymptote given by the line: y = x/2

2.two lines that intersect in a way that cuts both lines in half
3.two lines that intersect in a way that they share more than one common point
4.two lines that intersect in a way that forms two congruent angles
Answer:
Step-by-step explanation:
The correct definition of perpendicular lines is option 1: "Two lines that intersect in a way that forms right angles."
When two lines intersect to form four right angles (90-degree angles), they are said to be perpendicular to each other. The point at which the lines intersect is called the point of intersection.
Therefore, option 1 is the correct definitation of perpendicular lines.
Answer: 1. Two lines that intersect in a way that forms right angles.

Step-by-step explanation:
Notice that all y-intercepts are the same (doesn't give a clue to the answer).
The line has a downward slant as you move from left to right, so the slope is negative (eliminating A & C as answers).
Determine the actual slope by identifying the y-intercept and x-intercept, and calculate Rise over Run:
Rise = -6 (goes from +6 to 0)
Run = +12
-6/12 = -1/2
is y=-x directly proportional or non proportional
Answer: Directly proportional.
Step-by-step explanation:
y = -x is directly proportional for a few reasons.
➜ The graph of this equation is a straight line, so all the ratios of points are equal.
➜ The constant of proportionality (k) is equal to -1.
➜ This line intersects the graph at the origin (0, 0).

Suppose that the functions and are defined as follows.
The value of the function f/g is (x - 1) / (x + 8)
Let's start by writing out the functions we are given:
f(x) = 4 / (x + 8)
g(x) = x / (x - 1)
To find f/g, we need to divide f(x) by g(x). We can do this by multiplying f(x) by the reciprocal of g(x), which is (x - 1) / x. Multiplying f(x) by this reciprocal gives us:
f(x) * (x - 1) / x = 4 / (x + 8) * (x - 1) / x
To simplify this expression, we can first find a common denominator for the two fractions on the right-hand side:
4 / (x + 8) * (x - 1) / x = 4(x - 1) / x(x + 8)
Now we can simplify this expression by canceling out any common factors in the numerator and denominator. In this case, we can cancel out a factor of 4 and a factor of (x - 1):
4(x - 1) / x(x + 8) = (x - 1) / (x + 8)
Therefore, the quotient of f(x) and g(x), or f/g, is:
f/g = (x - 1) / (x + 8)
We can interpret this expression as a new function, h(x), where h(x) = f(x) / g(x) = (x - 1) / (x + 8). This new function takes a value of x and returns the ratio of f(x) to g(x) at that value.

a 10 x 10 x 10 cub is painter red on all faces and then cut into ten 10 x 10 x 1 slices each slice is then cut into twenty five 2 x 2 x 1 blocks how many of the 250 blocks have exactly on face painted red
There are exactly 250 blocks with exactly one face painted red.
What is cube ?
A cube is a three-dimensional solid shape with six square faces of equal size that meet at 90-degree angles. It is a special case of a rectangular prism, where all of the edges have the same length.
When the 10 x 10 x 10 cube is painted red on all faces, it means that all of the 1000 unit cubes inside the large cube are red.
When the cube is cut into ten 10 x 10 x 1 slices, each slice will contain 100 unit cubes. When each slice is cut into twenty-five 2 x 2 x 1 blocks, each block will contain 4 unit cubes.
Therefore, each 2 x 2 x 1 block will come from 4 unit cubes, and each unit cube will contribute to 4 different blocks.
To count the number of blocks with exactly one face painted red, we can focus on the blocks that have a red face on the bottom (or top) and three unpainted faces on the other sides. Each such block will correspond to one of the 100 unit cubes in a slice, and there are 10 slices, so there are 1000 such blocks in total.
However, each of these blocks has four unit cubes, so we need to divide by 4 to get the number of blocks. Therefore, the answer is:
1000 ÷ 4 = 250
Therefore, there are exactly 250 blocks with exactly one face painted red.

Bob wants to break the school record of scoring 30 points in his basketball game. He scored 13 points in the first half. How many two point baskets must Bob make in the second half to break the school record?
Bob needs to make at least 9 two-point baskets in the second half to break the school record of scoring 30 points in his basketball game.
To break the school record of scoring 30 points, Bob needs to score more than 30 points in his basketball game. Since he scored 13 points in the first half, he needs to score at least 17 points in the second half to break the record.
Let's assume that Bob makes x two-point baskets in the second half. Since each two-point basket contributes 2 points to his score, his total score from two-point baskets would be 2x.
Therefore, to break the school record, we need to solve the following inequality:
2x + 13 > 30
Subtracting 13 from both sides, we get:
2x > 17
Dividing both sides by 2, we get:

if (-8,3) lies on the circle and its Center is (-4,3) find the radius
If (-8,3) lies on the circle and its Center is (-4,3) then, the radius of the circle is 4.
We know that the center of the circle is (-4, 3). Let's call the radius of the circle "r".
The distance between the center of the circle and the point (-8, 3) on the circle is equal to the radius "r".
Using the distance formula, we can find the distance between these two points;
d =√[(x2 - x1)² + (y2 - y1)²]
d = √[(-8 - (-4))² + (3 - 3)²]
d = √[(-8 + 4)² + 0²]
d = √[4²]
d = 4
Since the distance between the center of the circle and the point on the circle is equal to the radius, we have;
r = d = 4

The endpoints of the latus rectum of the parabola equation is : f. The endpoints of the latus rectum are (-6, 9) and (-6, -15).
What is the latus rectum?Standard form of the equation of a parabola =y (x - h)² = 4p(y - k)
Where:
(h, k) = vertex
4p = distance between the vertex and focus
Comparing this with (x + 3)² = -20(y + 1) will gives us
(x + 3)² = -20(y + 1)
= (x - (-3))² = -20(y - (-1))
The vertex of the parabola is = (-3, -1)
4p = -20
p = -20/4
p = -5
The line that is perpendicular to the axis of symmetry (line y = -1) and passes through the focus (-3, -6) is known as the latus rectum of a parabola. The line y = - 6—the focus—and the directrix are separated by a distance of 4p = 20.
The vertex which is located at (-3, -1) is the latus rectum's midway. The latus rectum tend to has a length of 20 and passes through the points (-3, -1). Its endpoints must be located on the line x = -3 since it is perpendicular to the axis of symmetry.
The endpoints of the latus rectum are:

The value of angle JKN is 73°.
Given that the m ∠JKM = 106 degrees, m ∠LKM = 66, and KN bisects LKM.
So we need to find the value of ∠JKN,
So, using the angles addition postulate,
∠LKM = ∠LKN + ∠MKN
Therefore,
∠LKN = 66/2 [definition of bisector]
∠LKN = 33°
Again, using the angles addition postulate,
∠JKM = ∠JKL + ∠LKM
∠JKL = 106 - 66
∠JKL = 40°
