What happens when a transversal cuts a parallel line?
Corresponding angles are those that are located on the same side of the transversal and in identical relative positions to the parallel lines. Angles that correspond to one another have the same measure.
Alternate interior angles are those that are located on the transverse and within the area between the parallel lines, respectively. Congruent alternate interior angles exist.
Alternate external angles are those that are outside of the space between the parallel lines and on the opposing sides of the transversal. Congruent external angles exist between the two.

.
Show your work
Correct x and y
The solution to the system of equations is x = 1 and y = -3.
To solve the system of equations using the substitution or elimination method, let's start with the substitution method.
Given equations:
y = 4x - 7
4x + 2y = -2
We'll solve equation 1) for y and substitute it into equation 2):
Substituting y from equation 1) into equation 2):
4x + 2(4x - 7) = -2
4x + 8x - 14 = -2
12x - 14 = -2
Now, we'll solve this equation for x:
12x = -2 + 14
12x = 12
x = 12/12
x = 1
Now that we have the value of x, we can substitute it back into equation 1) to find y:
y = 4(1) - 7
y = 4 - 7
y = -3
Therefore, the solution to the system of equations is x = 1 and y = -3.

Answer:
y = 3x + 2
Step-by-step explanation:
y = mx + b format
the y and x will stay the same
when graphed, the points make a line that intersects with the y-axis at 2. This would be the y - intercept or "b" in our equation.
m stands for the slope of the line which is represented by rise/run. Going left to right, the line is going upwards which means that the slope will be positive. the distance between these given points is rise 3 and run 1. 3/1
3/1 is the same thing as 3 so your slope would be 3.
your final equation would be y = 3x + 2

Carl is making accessories for the soccer team. He uses 773.85 inches of fabric on headbands for 29 players and 4 coaches. He also uses 279.56 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
23.45 inches fabric was used on a headband and 9.64 inches fabric was used on a wristband for each player.
No. of players = 29
No. of coaches = 4
Total fabric used for headbands = 773.85 inches
Total no. of people for headbands = 29 + 4
= 33
Fabric used for headband for 1 person = 773.85/33
= 23.45 inches
Total fabric used for wristbands = 279.56 inches
Total no. of people for wristbands = 29
Fabric used for headband for 1 person = 279.56/29
= 9.64 inches

This is an increasing sequence, with -9 as its first term. The first increase is +3, then +5, +7, and +9. The differences increase by 2 each time. The sixth term will be 15 + 11, and the seventh would be 15 + 11 + 13. We can follow this pattern to get to the tenth term. 15 + 11 + 13 + 15 + 17 + 19 = 90
ariana's 150g bag of trail mix is x% raisins. brandon's 250g bag of trail mix is y% raisins. they combine the two mixes together in one bowl. *write an expression that shows the concentration of raisins in the resulting mix.
Answer:
(3x+5y)/8
Step-by-step explanation:
The total amount is 150+250=400
We then do (3x+5y)/2 × 1/400
This equals (3x+5y)/800
We multiply that by 100 giving us the final answer.
The expression that shows the concentration of raisins in the resulting mix is 600x+1000y
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, Ariana's 150g bag of trail mix is x% raisins. Brandon's 250g bag of trail mix is y% raisins. they combine the two mixes together in one bowl.
Raisins Ariana have = x% of 150
= 3x/2
Raisins Brandon have = y% of 250
= 5y/2
Total mix = 250 + 150
= 400 grams
Concentration of Raisins in the total mix = (3x/2 + 5y/2) of 400
= 600x+1000y
Hence, the expression that shows the concentration of raisins in the resulting mix is 600x+1000y

Trent needs a total of $320 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering newspapers. How many weeks will Trent have to deliver papers to have enough money to buy the bicycle?
Answer:
Trend wants to buy a new bicycle which costs 320$.
He has 35$ saved and earns 15$ each week.
After a number of weeks (a), the amount money he has: A = 35 + 15 x a
If Trend has enough money to buy that bicycle, we have the equation:
35 + 15 x a = 320
=> 15 x a = 320 - 35
=> 15 x a = 285
\(a = \frac{285}{15} = 19\)
=> After 19 weeks, Trent will have had enough money to buy that bicycle

Finde the value of x in the proportion ( 5x+ 1 ):3 =(2x +2): 7(6 x) = (4x) :7
In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.
In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.
To find the value of x in the given proportions, let's solve them one by one:
(5x + 1) : 3 = (2x + 2) : 7
To solve this proportion, we can cross-multiply:
7(5x + 1) = 3(2x + 2)
35x + 7 = 6x + 6
Subtracting 6x from both sides and subtracting 7 from both sides:
35x - 6x = 6 - 7
29x = -1
Dividing both sides by 29:
x = -1/29
Therefore, the value of x in the first proportion is -1/29.
(6x) : (4x) = 7
To solve this proportion, we can simplify the left side:
6x / 4x = 7
Dividing both sides by 2x:
3/2 = 7
This equation is not true, as 3/2 is not equal to 7.
Therefore, there is no value of x that satisfies the second proportion.
In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.

Elliot spent 3/7 of his money on some comics. He spent 1/4
of the remaining money on a pack of cards.
a) What fraction of Elliot's money has he left?
b) If he has $6 left, how much money did Elliot have at first?
Answer:
a) 3/7
b) $14
Step-by-step explanation:
let the total of his Money be x
on some comics = 3/7 of x
\( \frac{3}{7} \times x \: = \frac{3x}{7} \)
remaining money = x - 3x/7
\(x - \frac{3x}{7} = \frac{7x - 3x}{7} = \frac{4x}{7} \)
on a pack of cards = 1/4 of 4x/7
\( \frac{1}{4} \times \frac{4x}{7} = \frac{4x}{28} = \frac{x}{7} \)
a) left fraction = total money - all spent money
note that; all spent money = money spent on some comics and pack of cards
\(x - ( \frac{3x}{7} + \frac{x}{7} )\)
\(x - ( \frac{3x + x }{7} )\)
\(x - \frac{4x}{7} = \frac{7x - 4x}{7} = \frac{3x}{7} \)
left fraction = 3/7 of the money
b) left money = 3x/7
but since left money is $6
therefore, $6 = 3x/7
multiply both sides by 7
\(6 \times 7 = \frac{3x}{7} \times 7\)
42= 3x
divide both sides by 3
x = 42/3
x = 14

It costs $145 for 10 people to attend a concert. How much does it cost a group of 8 people?
Answer:
It would cost $116 for a group of 8 people.
Step-by-step explanation:
You would divide 145/10 to find the cost for 1 group (which would be $14.5). Then, you would multiply 14.5x8 to get your answer of $116.
Answer:
$116
Step-by-step explanation:
1. First, let's find how much it costs for 1 person to attend a concert by dividing 145 by 10.
\(\frac{145}{10}\) \(14.5\)2. Next, let's multiply 14.5 by 8.
\(14.5 * 8\) \(116\)Therefore, it costs a group of 8 people $116 to attend a concert.

What is the meaning of "\( \varphi (x,y)\) be \( y\wedge \phi (x)\) "?
The reasoning presented lacks explicit explanations and logical connections between the steps, making it difficult to fully understand the intended proof strategy.
The given proof aims to show that the Separation Axioms can be derived from the Replacement Schema using a particular construction involving a formula p(x, y). Let's analyze the proof step by step:
Define the formula p(x, y) as x = yo(x).
This formula states that for each x, y pair, x is equal to the unique object y such that y is obtained by applying the operation o to x.
Define the set F as {(x, x) (x)}.
This set F contains pairs (x, x) where x is the unique object obtained by applying the operation (x) to x.
Claim: F(X) = {y (x = X)p(x, y)} = {y: (x = X)x = y^o(x)} = {x: (3x € X)o(x)} = {x X: (x)}.
This claim asserts that F(X) is equivalent to {y (x = X)p(x, y)}, which is further equivalent to {y: (x = X)x = y^o(x)}, and so on.
The proof states that since (x, y) satisfies the functional formula VaVyVz(p(x, y)^(x, z) y = z), it follows that (x, y) is a functional formula.This step emphasizes that the formula p(x, y) satisfies certain properties that make it a functional formula, which is relevant for the subsequent deductions.
Finally, the proof concludes that the Separation Axioms follow from the Replacement Schema, based on the previous steps.
