Solve |6x+ 72| = 12 x Identify the solution and an extraneous solution.
solution x=12
extraneous solution x=-4
The solution of the absolute value equation is x = 12, and the extraneous solution is x = -4
How to solve the absolute value equation?Here we have the equation:
|6x + 72| = 12*x
Then we can rewrite this in two ways as:
6x + 72 = -12*x
6x + 72 = 12x
We can find two solutions for x. For the first one:
6x + 12x + 72 = 0
18x = -72
x = -72/18 = -4
For the other equation we get:
6x - 12x + 72 = 0
6x = 72
x = 72/6 = 12
Which is the extraneous solution?It is x = -4, because we will get:
|6*-4 + 72| = 12*-4
48 = -48

If e^5x=k, where k is any positive number then what is the value of x
Answer:
If [tex]k > 0[/tex], then [tex]x[/tex] must be greater than 0.
Step-by-step explanation:
If [tex]k > 0[/tex], then we state that [tex]e^{5\cdot x} > 0[/tex] and [tex]e^{5\cdot x}[/tex] is a trascendental function with a lower bound so that [tex]e^{5\cdot x}> 1[/tex]. Then, the minimum value of [tex]k[/tex] is 1 and we proceed to solve the latter equation to find the value of [tex]x[/tex]:
[tex]e^{5\cdot x}> 1[/tex]
[tex]\ln e^{5\cdot x} > \ln 1[/tex]
[tex]5\cdot x > 0[/tex]
[tex]x > 0[/tex]
Therefore, [tex]x[/tex] must be greater than 0.

percentage of a sale increase from $5 to $36
just divide the sale price from $36 to $5
$ 36
$ 5
= 7.2 (100%)
= 720 % ( a profit of $36 - $5 = $31 )

3 (2n + 4) - 2 = 1 +5 (n + 1)
Answer:
n = -4
Step-by-step explanation:
Start off by remembering PEMDAS which first P means parenthesis so use distributive property to multiply the 2n + 4 by the 3 in front of it and do the same to the n + 1 and multiply that by the 5 in front which turns your question into 6n+12-2=1+5n+5 so now i'd combine like terms on both sides which now gives you 6n + 10 = 5n +6 so now to get the n on one side i'm going to sub tact it from both sides doesnt matter which one you do but to make it easier i'd subtract the 5n from the 6n because the whole point is to solve for n and by doing that you'd already be getting it by itself. so now the question should look like n + 10 = 6 so subtract 10 from both sides to isolate the n and you get your answer n = -4
Answer:
N = - 4
Step-by-step explanation:
3 (2n+4)-2=1+5(n+1
distribute 3 through the paretheses
6n+12-2=1+5n
add the numbers
6n+10=6+5n
move constant to the right-hand side and change its sign
6n-5n=6-10
calculate the difference
n = - 4

Which would be the best measure of variability to use to compare the data?
Only Brand A data is symmetric, so standard deviation is the best measure to compare variability.
Only Brand B data is symmetric, so the median is the best measure to compare variability.
Both distributions are symmetric, so the mean is the best measure to compare variability.
Both distributions are skewed left, so the interquartile range is the best measure to compare variability.

Step-by-step explanation:
Sarah, Lacey, and Mark stuffed envelopes with invitations for parents to an open house.
• Sarah stuffed 10 more envelopes than Lacey.
• Mark stuffed 3 less than twice as many envelopes as Lacey.
• Altogether they stuffed 503 envelopes.
If x represents the number of envelopes that Lacey stuffed, which equation BEST represents this situation?
x+10+2x−3=503
x+10x+3−2x=503
x+x+10+2x−3=503
x+x+10+3−2x=503
Answer: x+x+10+2x−3=503
Step-by-step explanation:
Let's define 3 variables:
S = # of stuffed envelopes by Sarah.
X = # of stuffed envelopes by Lacey.
M = # of stuffed envelopes by Mark.
S = 10 + X.
M = 2*X - 3.
X + S + M = 503.
Now we can replace the first two equations into the third equation:
X + (10 + X) + (2*X - 3) = 503.
Then the correct option is: x+x+10+2x−3=503
Now we can also solve the equation, just because it is fun:
X + 10 + X + 2*X - 3 = 503
4*X + 7 = 503
4*X = 503 - 7 = 496
X = 496/4 = 124
Lacey stuffed 124 envelopes.

Answer:
6. The triangle is acute
m<P = 60
m<Q = 84
m<R = 36
----------------
7. Claim: the three angles added together equal 180 degrees
m<J = 116 degrees
m<K = 33 degrees
m<L = 38 degrees
Step-by-step explanation:
m<P = 4a + 12 = 4(12) + 12 = 60
m<Q = 7a = 7(12) = 84
m<R = 3a = 36
(4a + 12) + 7a + 3a = 180 degrees
14a + 12 = 180
14a = 168
a = 12
----------------
m<J = 4x + 12 = 4(26) + 12 = 116
m<K = x + 7 = 26 + 7 = 33
m<L = 2x - 14 = 2(26) - 14 = 38
(4x + 12) + (x + 7) + (2x - 14) = 180 degrees
7x - 2 = 180
7x = 182
x = 26

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The graph of the linear function shown in the image.
Now,
Two points on the graph are (3, 350) and (2, 250).
Hence, Rate of change = (250 - 350) / (2 - 3)
= -100/-1
= 100
Thus, The rate of change with respect to the number of deposit will be 100.
