write the converse of the statement below. then determine whether the statement is true or false. If false, give a counterexample. Conditional Statement: If 2 angles are corresponding in parallel lines, then they are congruent.
Answer:
Converse statement is ''If two angles are congruent, then they are corresponding angles in parallel lines''.
The converse statement is false.
Step-by-step explanation:
Statement is ''If 2 angles are corresponding in parallel lines, then they are congruent.''
Converse statement is ''If two angles are congruent, then they are corresponding angles in parallel lines''.
Consider the figure.
Here,
[tex]l||m[/tex]
As ∠1 and ∠2 are alternate interior angles,
∠1 ≅ ∠2
(if two lines are parallel then each pair of alternate interior angles is equal)
So, ∠1 ≅ ∠2 but ∠1 and ∠2 are alternate interior angles not corresponding angles.
The converse statement is false.
Mrs Santos has two kinds of flowers in her garden the ratio of Lily to daisies and the garden is three to two if there are 12 lilies what is the total number of Flowers in her garden
Answer:
its 8
Step-by-step explanation:
I just did the test
The total number of Flowers in her garden are, 20
We have to given that,
Mrs. Santos has two kinds of flowers in her garden,
And, the ratio of Lily to daisies and the garden is three to two.
Here, number of lilies = 12
Since, the ratio of Lily to daisies and the garden is,
3 : 2
So, Number of Lily = 3x
3x = 12
x = 12/3
x = 4
Hence, Number of daisies = 2x = 2 × 4 = 8
So, the total number of Flowers in her garden are,
⇒ 12 + 8
⇒ 20

find the inverse of the function f(x) = 5/6x +10
Answer:
[tex]\displaystyle f^{-1}(x)=\frac{6x-60}{5}[/tex]
Step-by-step explanation:
Inverse function
Given the function
[tex]\displaystyle f(x)=\frac{5}{6}x+10[/tex]
We find its inverse following the procedure below:
Set y=f(x)[tex]\displaystyle y=\frac{5}{6}x+10[/tex]
Multiply by 6:[tex]6y=5x+60[/tex]
Operate:[tex]5x=6y-60[/tex]
Solve for x:[tex]\displaystyle x=\frac{6y-60}{5}[/tex]
Swap variables:[tex]\displaystyle y=\frac{6x-60}{5}[/tex]
Make the new y the inverse function:[tex]\boxed{\displaystyle f^{-1}(x)=\frac{6x-60}{5}}[/tex]
This is the inverse function

Answer:
Which term best describes the relationship between <1 and <3? --------- Vertical Angle
Which angle is supplementary to <7? ---------- <8
Which of these explains why <4 ≅ <6? ------------ Alternate Interior angles
Step-by-step explanation:
Vertical angle -- are the angles opposite of each other when two lines cross
Supplementary -- Are angles that add up to 180°
Alternate interior -- are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.

What is |-6,035| ?
Plz help
Answer:
6,035
Step-by-step explanation:
(Forgive me, I'm not awesome at explaining). You are calculating the absolute value. For this you will be ignoring the negative sign if it is in-between the lines. Or, to simply put it, how far away it is from 0 on a number line, you can use a number line to calculate this for smaller numbers but 6,035 is waaaaay too big. So, I just ignore the negative because, for example, you wouldn't say you were -6 miles away from your house, you would say you were 6 miles away. That's kind of what we are doing here. If the negative was OUTSIDE of the lines then it wouldn't be cancelled out. Ex. -|2| it is 2 away from 0, BUT you need to add on the negative making the answer to the -2. I hope this helped I'm not good with explaining!

distance between (4, –1) and (8, –1)?
Answer: 4
Step-by-step explanation: compute the distance between (x1, y1), (x2, y2):
(8 -4)² + [ -1 - (-1) ]² = 4
Answer:
4
Step-by-step explanation:
X1 = 4
X2= 8
Y1 = -1
Y2= -1
Distance Formula = √(X2-X1)² + (Y2-y1)²
Step 1. calculate (X2-X1)²
(8 - 4)2 = 16
Step 2. calculate (Y2-Y1)²
(-1 - -1)2 = 0
Step 3. calculate √16 + 0
= 4

A newly appointment school district superintendent releases a plan for the next 20 years that affects the schools within the boundaries of the district. In this plan, there is new policy that states that if a high school has less than 100 students, then the school will be shut down. Calamanco High School has a population of 1,417 students, but it is losing students at an average rate of 109 students per year. This school used to house more than 5,000 students but the district has been struggling in recent years and losing people to more affluent nearby districts and cities. Some communities are concerned about this decreasing rate because there will be a time when the district may shut the school down. Let x represent the number of full years that the school is operational.

Answer:
x=1, y=2
Step-by-step explanation:
Answer: x = 13 and y = -2
Step-by-step explanation:
You need to use the elimination method for each equation, so that means being able to cross them out by equaling them to 0. You can choose x value or the y value, since you need to do 2 things to the y value I will show you an easier way with the x value since it is equal to one in the top equation.
Looking at the bottom equation, you need to find a way to set the x equation to cross 2x out making it 0. Removing x from this, how can you make 2 end up being 0? Subtract 2 from it, but x is not -2 on the first equation, so you have to times everything in that equation by -2 to make x -2.
so basically,
-2(x + 3y = 7)
your new equation is
-2x -6y = -14
put your other equation under it to eliminate the x value finally.
-2x -6y = -14
2x + 2y = 6
so you only need to combine like terms. X is no longer included because x is eliminated.
-4y = 8
divide to find the value of y
Y = -2
plug your newly found equation in for y in the original equation (either one is fine.
x + 3(-2) = 7
x -6 = 7
add 6 to both sides
x = 13

A group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the trip. Each small car can hold 5 people and each large car can hold 8 people. A total of 5 cars were rented which can hold 34 people altogether. Determine the number of small cars rented and the number of large cars rented.
Answer:
2 small; 3 large
Step-by-step explanation:
Using s and L for the number of small and large cars, respectively, we have ...
5s +8L = 34 . . . . number of passengers
s + L = 5 . . . . . . . number of cars
5s +8(5 -s) = 34 . . . . substitute for L
-3s +40 = 34
-3s = -6 . . . . . . subtract 40
s = 2 . . . . . . . . divide by -2
L = 5-2 = 3
2 small cars and 3 large cars were rented.
The scale factor from EFGH to ABCD is 2
Answer:
Close, but the answer is 1/2
Step-by-step explanation:
The answer would be 2 when you are finding the scale factor of ABCD to EFGH, but since it is going from EFGH to ABCD, then all you have to do is divide by 2 or multiply by 1/2.
EFGH to ABCD= 12 • 1/2 = 6 or 12 ÷ 2 = 6
