What is the distance between the points M (-3, 7) and N (a, b)?
Answer: [tex]\sqrt{ (-3-a)^2 + (7-b)^2 }[/tex]
Explanation:
We plug the given coordinates into the distance formula
[tex]d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2 }\\\\[/tex]
There isn't much we can do from there since we don't know the values of 'a' or 'b'. You could expand out each binomial, but it's more simplified being factored like that.

Sally received a $30 gift card that could be used to download songs. After she downloaded 7 songs , she had $15 remaining on her gift card. If each song costs the same amount to download, what is the cost of one song?
Answer:
Step-by-step explanation:
2 dalliers and 14 cents
Answer:
$2.14285714286 or $2.14
Step-by-step explanation:
This is quite simple.
#1. Take-away $15 from $30 because "$15 remain"ed.
#2. Then you get $15 dollars and divide that by 7, because she used the "same amount to download" each song so you divide 15 among 7 equally.
#3. There you go! You have the answer! it's: $2.14285714286 or $2.14 if simplified.

10 - w = 1.5 Find w.
Answer:
8.5
Step-by-step explanation:
w is 8.5
Answer:
8.5
Step-by-step explanation:
-w=1.5-10 the opposite of 10 is negative 10
-w=-8.5
w=8.5 you are trying to get just w not negative w
so two negatives equal a positive or -1
times -8.5 is a positive 8.5
Four less than the product of 6 and a number equals 3
Answer:
-1/6 (written as a fraction)
Step-by-step explanation:
our goal here is to get n by itself
6n-4=3
add 4 to both sides
6n=-1
divide both sides by 6
n= -1/6 (a fraction)
Thomas bought 4 shirts from a store. The price of each shirt was the same. After he bought the shirts, his account balance showed a change of −$89.08. What would have been the change to Thomas's account balance had he only bought 1 shirt from the store?
A. $22.27
B. -$22.27
C. $22.45
D. -$22.45
Answer:
B. -22.27
Step-by-step explanation:
To find the answer just divide the acount balance after he bought the 4 shirts by 4 to get the answer of what his balance would be after he bought 1 shirt.
8 + z = 19. step equations
Answer:
11
Step-by-step explanation:
First subtract
19-8= Z
So solution would be
Z=11
Answer:
z=11
Step-by-step explanation:
step 1:simplify both sides of the equation
z+8=19
step 2:subtract 8 from each side
z+8-8=19-8

Compare and contrast a postulate , theorem and a conjecture
Answer:
Postulates and conjectures are similar in that they are both used in mathematical proofs. The difference between them is that whilst a conjecture is a opinion that is put forward without proof, and that simply represents a belief, a postulate it something that is assumed true (but still does not have any proof behind it).
Step-by-step explanation:
Answer: Postulate – this is also called as axiom. This study is accepted without asking for any proof. This is considered as true without further proof. IT is simply considered as self-evident. It is usually agreed by anyone to be true and acceptable.
Example of postulate is to prove a simple triangle as congruent.
While conjecture – considered as proposition in which it needs to provide value proof or evident in order for it to be considered as true.
Examples of conjecture are four color theorems and Fermat’s Last theorem.

(10, y) and (3, 4); m= -2/7 find missing value
Answer:
y2 -y1 =4 - y = 2 y has to = 2 because your slope m= - 2/7
x2-x1 =3-10 = -7
Step-by-step explanation:
( 10 , y ) (3 , 4)
x1 y1 x2 y2
We have that for the Question "(10, y) and (3, 4); m= -2/7 find missing value" it can be said that
The value of y is
y=8
From the question we are told
(10, y) and (3, 4); m= -2/7 find missing value
Generally the equation for the slope m is mathematically given as
[tex]m=\frac{y2-y1}{x2-x1}\\\\Therefore\\\\m=\frac{y2-y1}{x2-x1}\\\\-2/7=\frac{4-y}{3-10}\\\\-2/7*-7=4-y\\\\y=4((-2/7)*-7)\\\\[/tex]
y=8
Therefore
The value of y is
y=8

Which of the following statements is TRUE about parallel lines pq and rs?
a° and c° are alternate interior angles
a° and c° are alternate exterior angles
a° and c° are corresponding angles
a° and c° are vertical angles
Answer:
a and c are alternate interior angles
For the parallel lines pq and rs a° and c° are alternate interior angles. Option A is correct.
What are parallel lines?Parallel lines are defined as identical lines with identical orientations, parallel lines never intersect each other but meet at infinity.
Here,
When two parallel lines is intersect by a transversal line then the angles made facing the region between the parallel lines are said to be interior angles, And as we know that alternate angles for parallel lines are always equal. So a° and c° are alternate interior angles.
Thus, a° and c° are alternate interior angles.

Find the ratio of the number of boys to the number of girls to the total number of children (always in the simplest form).
Answer:
Ratio of number of boys to girls= 2:3
Ratio of number of boys to girls to total number of children= 2:3:5
Step-by-step explanation:
42 boys and 63 girls took part in an art competition
The ratio of the number of boys to the number of girls can be calculated as follows
= 42/63
= 2:3
The ratio of the number of boys to girls to total number of children can be calculated as follows
= 42/63/105
= 2:3:5
