K is between J and M. L is
between K and M. M is
between K and N. If JN = 14, KM = 4, and JK = KL = LM, what is NL?
(do step-by-step fully pls)
Step-by-step explanation:
given,
K is between J and M, L is between K and M, M is between K and N. JN = 14, KM=4 and JK= KL= LM
NL=?
according to the question,
J-------K-------L------M--------N
We know,
KM= 4
KL+LM=4
KL+KL=4 (LM=KM)
2KL=4
KL=2
SO,
JK=KL=2 and LM=KL=2
we have ,
JN=14
JK+KM+MN= 14
2+4+MN=14
MN=8
Now,
NL=LM+MN= 2+8= 10

Step-by-step explanation:
-5r - 3r
Combine like terms
Factor out r
r( -5-3)
-8r
Answer:
like bases combine under add/subtract
-5 minus 3 is -8
-8r would be the solution

Find three consecutive even integers such that five times the second is six more than twice the sum
of the first and third integers
Answer:
The first number = 4The second number = 6The third number = 8Step-by-step explanation:
Let all unknown numbers be represented by the variable x.So;x = first number
x + 2 = second number
x + 4 = third number
placing in a form as demanded by the question.5(x + 2) = 6 + 2x + 2 ( x + 4)
5x + 10 = 6 + 2x + 2x +8
5x - 4x = 14 - 10
x = 4
Therefore;The first number (x) = 4
The second number ( x + 2) = 4 + 2 = 6
The third number (x + 4) = 4 + 4 = 8
Answer:
2x + 2x +2 + 2x +4 = 6x +6 =Sum
5 * (2x +2) = 2 * (2x + 2x +4) +6
10x + 10 = 8x + 8 + 6
2x = 4
x = 2
So the numbers are:
2x or 4
2 x + 2 = 6
2x + 4 = 8
Double-Check
5 * 2nd integer = 30
2 * (1st + 3rd integers) = 24
30 is 6 more than 24

2. Find the domain of the function (f/g)(x) where f (x)= x^2 – 9 and g(x)= x^2 - 4x+3
A (-infinity, infinity)
B (-infinity, 1) (1, infinity)
C (infinity, 1) (1,3) (3, infinity)
D (-infinty, -3) (-3,-1)(-1, infinity)
Answer:
I think you mean C.
Step-by-step explanation:
f(x) / g(x) = (x + 3)(x - 3)
==========
(x - 3)(x - 1)
f(x)/g(x) = (x+3) / (x - 1)

A three-sided figure with angle measures of 60°, 60°, and 40°.
X.
Y.
Z.
OA. Y
OB. Z
OC. X
OD. The shape is nonexistent.
Answer:
OD for a triangle to exist it must equal 180 degrees as a final and this one only equals 160
Answer:
D. The shape is nonexistent.
Step-by-step explanation:
A triangle's angles must add up to 180 degrees.
60+60+40 is 160.

solve this -8+0.75z=12-0.25z
Answer:
z = 20Step-by-step explanation:
-8+0.75z=12-0.25zTranspose '-8' from LHS to RHS
So,
[tex] 0.75z = 12 + 8 - 0.25z[/tex]
Then transpose '0.25z' from RHS to LHS
So,
[tex]0.75z + 0.25z = 20 \\ 1z = 20[/tex]
So therfore z = 20

Martin spent $300 from his savings account on a new bike. He also deposited $300 in his savings account that he earned from selling his used textbooks. Which integer represents the change in Martin's savings? A) $100 B $0
C. -100$ D. -$200
Answer:
B
Step-by-step explanation:
a money account works in the same way as real things we can touch.
so, when I have 300 apples at a place (e.g. a grocery store), then I take away 300 apples, and then put again 300 apples there - how many apples will be there at that moment ?
we had 300 and took away 300.
300 - 300 = 0
at that moment we have 0 apples.
but then we put again 300 apples there.
0 + 300 = 300
so, we end up with 300 apples. the same number we started with.
and the same way for the savings account.
he takes out $300.
that means he has now $300 less on his account.
and then he adds $300.
so, he added exactly the same amount as he took out earlier, which means nothing else than that he undid his earlier action regarding his bank account.
so, his balance is now exactly the same as before he did the first transaction.
therefore the change is exactly : $0

Determine if v 49 is rational or irrational and give a reason for your answer.
The number 49 is rational
because
Step-by-step explanation:
If a number is rational, we can represent it as a fraction.
[tex] \frac{a}{b} [/tex]
Where a and b are intergers.
First, we know that
[tex] \sqrt{49} = 7[/tex]
We can represent 7 as
[tex] \frac{7}{1} ..... \frac{14}{2} .... \frac{21}{3} ..... \frac{n}{y} = 7[/tex]
Where n and y are two numbers that when divided equal 7.
So
