Find the slope of a line with x-intercept 5 and y-intercept -3.
Answer:
3/5
Step-by-step explanation:
When you are given an x-intercept, the y value will always be 0.
When you are given a y-intercept, the x value will always be 0.
With the intercepts we are given, we can make two points we can solve for the slope with.

Move point A to different locations to change the orientation of the parallel lines. (You'll notice that the tool keeps AB and CD parallel to each other) Be sure that points A and B do not cross EF. Do the relationships among the angles that you noted in questions 2 through 4 change if you modify the set of parallel lines this way? Explain.
Answer:

No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
How to explain the parallel linesIf we modify the set of parallel lines by moving point A to different locations while ensuring that points A and B do not cross line EF, the relationships among the angles will not change. The statements regarding pairs of alternate interior angles being congruent, pairs of alternate exterior angles being congruent, and pairs of same-side interior angles being supplementary will still hold true.
The reason for this is that the properties of alternate interior angles, alternate exterior angles, and same-side interior angles are dependent on the fact that lines AB and CD are parallel. As long as AB and CD remain parallel, regardless of the position of point A, these angle relationships will remain consistent.

Jennifer bought some tulips, lilies, and roses to make bouquets. She bought the same number of tulips as lilies. She bought three more roses than tulips and lilies combined. She paid 18 cents for each tulip. The lilies were 27 cents per flower, and the roses cost 55 cents each. How many of each kind of flower did Jennifer buy if she paid $17.15 in all?
Answer:
z = 18.5
y = 15.5
x = 15.5
Step-by-step explanation:
Let
tulips = x
lilies = y
roses = z
x = y
z= x + 3 or y + 3
The equation is
0.18x + 0.27y + 0.55z = 17.15
Substitute x = y and z = y + 3 into the equation
0.18y + 0.27y + 0.55(y + 3) = 17.15
0.18y + 0.27y + 0.55y + 1.65 = 17.15
y = 17.15 - 1.65
= 15.5
x = y
x = 15.5
z = x + 3
= 15.5 + 3
= 18.5
Therefore,
z = 18.5
y = 15.5
x = 15.5

A group of 5 friends move into an apartment together to save on rent. The total monthly rent of the apartment is $4750 . Since the bedrooms are different sizes, the friends decide that each person should pay a different amount instead of splitting the rent evenly.
One of the friends named Nicole notices that her monthly rent is
D dollars less than it would be if the rent was split evenly. What is Nicole's monthly rent? Write your answer as an algebraic expression.
Answer: 950 - d
Step-by-step explanation:
4750 / 5 friends = 950.
then d dollars less is 950-d

81 divided by 7 plz just answer it
Answer:
11.57142857 (it doesn't go in evenly)
the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.
When dividing 81 by 7, we can determine how many times 7 can be subtracted from 81 without going into negative values. By repeatedly subtracting 7 from 81, we find that 7 can be subtracted 11 times before reaching 4, which is less than 7. Therefore, the quotient is 11. However, there is a remainder of 4 left over.
So, the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.

Olivia Earns $14 per hour at her job and receives a weekly bonus $100. Her total pay for the week of X hours is given by f(x)=100+14x. What is the reasonable domain and range?
Answer:
Step-by-step explanation:
Given the total pay for the week of X hours given by f(x)=100+14x, the domain of the function is the value of the input variable x for which the function exists. Since her to total week cannnot be negative, hence the value of x for which the function occurs is on all positive integers. This is represented according to the set notation;
Domain = [0, ∞)
The range of the function is the value of the output variable f(x) for all vaues of x for which the function occurs. Snce the minimum value of x is 0, the minimum value of the function will be at f(0);
f(0) = 100 + 14(0)
f(0) = 100 + 0
f(0) = 100
Hence the range of the function will be expressed as;
Range = [100, ∞)

please help...given that elm and oak street are parallel, find m
Answer:
102°
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
m∠A = (3×38 - 12)° = 102°
Answer:
∠a = 3x -12 ( Being corresponding angle)
Now
(3x-12) + (2x + 2) = 180 ( Sum of straight angles)
5x - 10 = 180
5x = 190
x = 38
m∠a = 3x -12 = 3*38 -12 = 102
