Only the x is minus. You know this because if you rotate the x axis 90 degrees clockwise, the plus axis will be on your right and the minus part of the axis on your left.The other 2 (y and z) are positive.All answers give - 4 in their choices. You are not helped much by -4y is on your left right now. That is the plus direction so y = 5z is 6 units up, so it is positive.Answer (-4,5,6)

Given: ABCD is a parallelogram.
Prove: ∠A ≅ ∠C and ∠B ≅ ∠D
Parallelogram A B C D is shown.
By the definition of a ▱, AD∥BC and AB∥DC.
Using, AD as a transversal, ∠A and ∠
are same-side interior angles, so they are
. Using side
as a transversal, ∠B and ∠C are same-side interior angles, so they are supplementary. Using AB as a transversal, ∠A and ∠B are same-side interior angles, so they are supplementary.
Therefore, ∠A is congruent to ∠C because they are supplements of the same angle. Similarly, ∠B is congruent to ∠

A parallelogram is a quadrilateral with four sides and the opposite sides of the parallelogram are equal and parallel.
How to show the proof?In the given figure, AB||DC. AD is the transversal, such that:
∠A + ∠D = 180-degrees.
The parallelogram is a quadrilateral with equal such that the interior angles present on the same side of the transversal are supplementary. The sum of supplementary angles is equal to 180-degrees.
From the theorem of same-side interior angles, the supplementary angles present on the parallel lines must be intersected by a transversal.
From the property of transversal, the interior angles on the same side of the transversal are supplementary. Therefore, ∠A and ∠D are supplementary and their sum is equivalent to 180-degrees.

Interest 3% in decimal form is .03
interest in ONE year 7000 * .03
interest in SEVEN years 7000 * .07 * 7
this is added to the original deposit of 7000
to become 7000 + 7000 * .03 * 7

Given that:-
Kyle and Lauren teach swimming lessons during the summer. Kyle has 8 classes with g students in each class and 6 classes with h students in each class. Lauren has 5 classes with g students in each class and 10 classes with h students in each class.If Kyle has a total of 62 students and Lauren has a total of 70 students,The equation made by the given situation is:-
For kyle, there are g students attending 8 classes sp total number of students will be 8g similarly for h students there are 6 classes so the total number of h students will be 6h. The total number of students for both g and h students attending kyle's class is 62. So the equation will be given as:-
8g + 6h = 62
Now for Lauren, there are g students attending 5 classes so the total number of students will be 5g similarly for h students there are 10 classes so the total number of h students will be 10h. The total number of students for both g and h students attending Lauren's class is 70. So the equation will be given as:-
5g + 10h = 70
Therefore the equation which shows the situation are 8g + 6h = 62 and 5g + 10h = 70.

Hi there !
What is a Pythagoras theorem ?
Nonsense = Reported
Thank you
Answers
Answer:
Hi! I think you are referring to the Pythagorean Theorem.
Essentially, given a right triangle, the sum of the squares of the shorter sides equals the square of the longer (slant) side or hypotenuse.
The formula is a squared + b squared = c squared
If the triangle has side lengths 3 and 4 (for the shorter sides), the longer side can be solved like this:
3 squared + 4 squared = x squared
(Let x = the longer side)
3 squared = 9
4 squared = 16
9+16 = x squared
25 = x squared
x = 5
So there you go, that's the Pythagorean theorem.
Let me know if this helped!
Answer:
a theorem attributed to Pythagoras that the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

A. It always has an x coordinate of 0.
B. It always has any coordinate of 0
C. Both x and y coordinates are 0.
Answers
Answer:
It always has an x coord of 0
The first step that we must take before attempting to solve a problem is to understand what it is asking for and what is given to us to help solve the problem. Looking at the problem statement, we can see that they are asking what is true about the y-intercept. We are given the information that the y-intercept is the place where a line crosses the y-axis.
Now that we have collected all that information, let us move onto understanding and solving the problem. So first of all, using the information that was given to us, we know that the y-intercept is the place where a line crosses the y-axis. The y-axis occurs where the x-coordinate is 0 and the x-axis occurs where the y-coordinate is 0. Therefore, the option that would best fit the description that we have would be option A, it always has an x coordinate of 0.

Sophia determined that the expression Negative (4 x minus 5) + 2 (x minus 3) is equivalent to –2x – 5 by using the steps below.
Expression: Negative (4 x minus 5) + 2 (x minus 3)
Expression: –2x – 5
Step 1:
Choose a value of x
Choose x = 1.
Choose x = negative 1.
Step 2: Substitute
Negative (4 (1) minus 5) + 2 (1 minus 3)
Negative 2 (negative 1) minus 5
Step 3: Evaluate
Negative (4 (1) minus 5) + 2 (1 minus 3) = negative (negative 1) + 2 (negative 2) = negative 3
Negative 2 (negative 1) minus 5 = 2 minus 5 = negative 3
Step 4:
Compare
Since –3 = –3, the two expressions are equivalent.
Which explains whether Sophia is correct?
She is correct because the value of the two expressions are the same in Step 3.
She is correct because she substituted opposite values in Step 1.
She is not correct because she did not substitute the same number in both expressions in Step 1.
She is not correct because she did not perform the correct order of operations in Step 3.
Answers
The correct statement is:
"She is not correct because she did not substitute the same number in both expressions in Step 1."
Is Sophia correct?First, let's see if Sophia is correct.
She starts with the expression:
-(4x - 5) + 2*(x - 3) = -2x - 5
Expanding the left side:
-4x + 5 + 2x - 6 = -2x - 5
-2x -1 = -2x - 5
So the constant term is different.
Now, what Sophia does is evaluating in x = 1 and x = -1. You can't do that when finding equivalent expressions. (never evaluate in different numbers).

The rat population in a major metropolitan city is given by the formula n(t)=89e^0.02t where t is measured in years since 1992 and n(t) is measured in millions
What was the rat population in 1992?
What does the model predict the rat population was in the year 2003?
Answers
Answer:
See below ~
Step-by-step explanation:
What was the rat population in 1992?⇒ t represents the years after 1992
⇒ So, in 1992, t = 0
⇒ Apply in the formula
⇒ n(0) = 89e^(0.02 × 0)
⇒ n(0) = 89e⁰
⇒ n(0) = 89,000,000
The rat population in 1992 was 89,000,000.
===========================================================
What does the model predict the rat population was in the year 2003?⇒ Number of years after 1992 : 2003 - 1992 = 11
⇒ Substitute for t in the formula
⇒ n(11) = 89e^(0.02 × 11)
⇒ n(11) = 89e^(0.22)
⇒ n(11) = 89 × 1.24607673
⇒ n(11) = 110,900,829 rats
The model predicts that in the year 2003 there will be a rat population of 110,900,829 rats.
Answer:
(a) 89,000,000 rats
(b) 110,900,829 rats
Explanation:
Given equation:

insert t = 0
n(0) = 89e^0.02(0) = 89 million ≈ 89,000,000To find the rat population in 2003 (after 11 years):
