Step-by-step explanation:
Well you first have to find the slope, which is y2-y1/x2-x1
Which is -12-7/5-5 and that equals to undefined.
So since you can't find the slope the answer should be undefined.

Given ∠A and ∠B are vertical angles with m∠A=20x+10 and m∠B=30x−10 .
What is x?
Enter your answer in the box
PLEASE HELP I APPRECIATE IT
Answer:
x = 2
Step-by-step explanation:
Vertical angles are equal to each other. It means that,
∠A = ∠B
So,
20x+10 = 30x−10
Taking like terms together, we get :
20x-30x=-10-10
-10x=-20
x=2
So, the value of x is 2.

A $55 pair of shoes was discounted 15 percent, making the sale price $46.75. The discounted price was then discounted again by 10 percent. Explain how you would find the final price of the shoes.
Answer:
Hi there
Your answer is
$42.08
To find the final price of the shoes, we would use the 15% discounted price, $46.75, as 100% and find 10% discount of that.
46.75 = 100%
/10
4.675 = 10%
Now, subtract 10% from the 15% discounted price
46.75 - 4.675 = 42.075$ Round up
$42.08
Answer:
find the final price by subtracting 10% from the sale price of $46.75 which is $4.68 making the final price $42.07

There are 40 students in a class. The teacher gave each female student 5
counters and each male student 3 counters. After the distribution of the
counters, the teacher realized that the female students had 128 more counters
than the male students,
Thus the required number of male and female students are 9 and 31 respectively.
Mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
here,
Let the number of male students is x and the number of female students be y,
According to the question,
x + y = 40
x = 40 - y ----- (1)
Now,
again from the question,
5y = 3x + 128
3x = 5y - 128
from equation 1
3 (40 - y) = 5y -128
120 - 3y = 5y - 128
120 + 128 = 8y
8y = 248
y = 31
Now,
From equation 1
x = 40 - y
x = 40 - 31
x = 9
Thus the required number of male and female students are 9 and 31 respectively.

The equation 320=x+7.50(36) represents the cost of ordering potted plants at a second store.
What does the x represent in this situation?
Answer:
I would say it's the amount of potted plants.
Step-by-step explanation:
x is the independent variable and y is the dependent variable. Y counts on x, so total cost counts on the amount of potted plants.

1. In ABC, A=45 degrees, B=75 degrees, and BC=12. What is the length of AB?
We know that sum of the interior angles of any triangle equal 180° :
So :
A + B + C = 180°
45° + 75° + C = 180°
120° + C = 180°
Both sides minus ( 120°) :
C = 180° - 120°
C = 60°
_________________________________
According to the theorem of sinuses :
[tex] \frac{AB}{ \sin(C) } = \frac{BC}{ \sin(A) } \\ [/tex]
[tex] \frac{AB}{ \sin(60) } = \frac{12}{ \sin(45) } \\ [/tex]
[tex] \frac{AB}{ \frac{ \sqrt{3} }{2} } = \frac{12}{ \frac{ \sqrt{2} }{2} } \\ [/tex]
[tex]Multiply \: both \: sides \: by \: \frac{ \sqrt{3} }{2} [/tex]
[tex] AB = \frac{24}{ \sqrt{2} } \times \frac{ \sqrt{3} }{2} \\ [/tex]
[tex]AB = \frac{12 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{2 \times 6 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{ ({ \sqrt{2} })^{2} \times 6 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{ \sqrt{2} \times \sqrt{2} \times 6 \sqrt{3} }{ \sqrt{2} } \\ [/tex]
[tex]AB = \frac{ \sqrt{2} \times 6 \sqrt{3} }{1} \\ [/tex]
[tex]AB = \sqrt{2} \times 6 \sqrt{3} [/tex]
[tex]AB = 6 \sqrt{2 \times 3} [/tex]
[tex]AB = 6 \sqrt{6} [/tex]

How many baby elephants were weighed?
Please help as soon as possible.
Answer:
just remember that each baby elephant weight 3/8 of a ton
and all together weight 3/4 of a ton
so how many baby elephants will be ,let be x a unknown number of them
so
x*(3/8) =3/4
because multiplying the number of baby elephants with their body weight gives the total weight of all baby elephants.
so
x=(3/4)*(8/4)=2
the number of baby elephants is 2
The area of a square is given by A= s2 where s is the length of each side of the square if the area of a square room is 64 square meters what is the length of 1 side of the room in meters
9514 1404 393
Answer:
8 m
Step-by-step explanation:
Using the given information, we know that ...
64 m^2 = A = s^2
(8 m)^2 = s^2
8 m = s
The length of one side of the room is 8 meters.

Answer: yes
Step-by-step explanation:
Two angles in a triangle are equal and their sum is equal to the third angle in the triangle. What are the measures of each of the three interior angles?
Answer:
45º, 45º, 90º
Step-by-step explanation:
Assume angles are x then third is x+x = 2x.
sum of angles in a triangle = 180
=> x + x + 2x = 180
=> 4x = 180
=> x = 180/4 = 45
so, angles are 45,45 and 90.

Step-by-step explanation:
Which equation is equivalent to 2x+3y=12
some possible equations equivalent to 2x+3y=12 would be:
1)
y=−2x+12/3
written form:
y= negative 2x plus 12 over/divided by 3
2)
y=−2/3x+4
written form:
y= negative 2 over/divided by 3x plus 4
3)
y=4−2/3x
written form:
y= 4 minus 2 over/divided by 3x
4)
y=12−2x/3
written form:
y= 12 minus 2x over/divided by 3
those are all i could think of! Hope this helped :)

The equivalent expression for the equation 2x + 3y = 12 are:
x = 6 - 3y/2
y = 4 - 2x/3
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
2x + 3y = 12
We need to find an equivalent expression for this equation.
We can have many forms:
Case 1.
2x + 3y = 12
Subtracting 3y on both sides.
2x + 3y - 3y = 12 - 3y
2x = 12 - 3y
Dividing 2 into both sides.
x = 12/2 - 3y/2
x = 6 - 3y/2
Case 2.
2x + 3y = 12
Subtracting 2x on both sides.
2x + 3y - 2x = 12 - 2x
3y = 12 - 2x
Dividing 3 into both sides.
y = 12/3 - 2x/3
y = 4 - 2x/3
Thus the equivalent expression for the equation 2x + 3y = 12 are:
x = 6 - 3y/2
y = 4 - 2x/3
