will a one variable equation always have only one solution
Answer:
Every linear equation that is a conditional equation has one solution. However, not every linear equation in one variable has a single solution. There are two other cases: no solution and the solution set of all real numbers. ... Therefore, the equation is always true.
Step-by-step explanation:
We want to see if a one-variable equation always has only one solution.
This is false, as one-variable equations can have no solutions or more than one solution.
So we start with the statement:
"A one-variable equation always has only one solution".
We need to find a counterexample to prove that this is false, and there are really easy counterexamples, like:
x^2 - 4 = 0
This is a one-variable equation, and solving it we have:
x^2 = 4
x = ± √4 = ±2
So here we have two solutions, 2 and -2, thus the statement is false.

Solve the system of linear equations by elimination. Check your solution. 3x + 2y = 7 -3x + 4y = 5
Answer:
(3x+2y=7-3x+4y)=5
3x+3x+2y-4y-7=5
6x-2y-7=5
6x-2y=5+7
=12
2(3x-y)=12
3x-y=12/2

In triangle KLM, the measure of angle M is 90 degrees, the measure of angle K is 75 degrees, and LM is equal to 6.3 feet. Find the length of KL to the nearest tenth of a foot.
Answer:
6.5feet
Step-by-step explanation:
Using the SOH CAH TOA identity
<K = 75 degrees
opposite = LM = 6.3 feet
Hypotenuse = KL
sin theta = opp/hyp
sin 75 = 6.3/x
x = 6.3/sin75
x = 6.3/0.9659
x = 6.5feet
Hence the length of KL to the nearest tenth of a foot is 6.5feet

The means and mean absolute deviations of the amount of rain that fell each day in a local city, last week and this week, are shown below. Means and Mean Absolute Deviations of Rainfall Last Week and This Week Last Week This Week Mean 3.5 in. 2.7 in. Mean Absolute Deviation 1.2 in. 0.5 in. Which expression compares the difference of the two means to this week's mean absolute deviation?
Answer:
0.8 / 0.5
Step-by-step explanation:
Given :
Deviations of Rainfall :
______Last Week ____ This Week
Mean___ 3.5 in. ________2.7 in
MAD ___ 1.2 in _________ 0.5 in
Mean difference = 3.5 in - 2.7 in = 0.8 in
This week's mean absolute deviation = 0.5 in
Mean difference / this week's mean absolute deviation
= 0.8 / 0.5
Answer:
0.8 / 0.5

Using properties of logarithms in excersises 13-18, use the properties of logarithms o write the logarithm in terms of log3(5) and log3(7) log3 (21/5)
Answer:
[tex]log_3(\frac{21}{5}) = log_3(7) - log_3(5)+ 1[/tex]
Step-by-step explanation:
Given
[tex]log_3(\frac{21}{5})[/tex]
Required
Express in terms of [tex]log_3(5)[/tex] and [tex]log_3(7)[/tex]
[tex]log_3(\frac{21}{5})[/tex]
Express 21 as 7 * 3
[tex]log_3(\frac{21}{5}) = log_3(\frac{7 * 3}{5})[/tex]
Apply law of logarithm
[tex]log_3(\frac{21}{5}) = log_3(7) + log_3(3) - log_3(5)[/tex]
[tex]log_3(3) = 1[/tex]. So, we have:
[tex]log_3(\frac{21}{5}) = log_3(7) + 1 - log_3(5)[/tex]
Rewrite:
[tex]log_3(\frac{21}{5}) = log_3(7) - log_3(5)+ 1[/tex]

Mare has a monthly cell phone plan that has a fixed charge of $12 per month plus
$0.30 per text message. Marie wants to spend no more than $40 per month on her
call phone. Which inequality represents the number of text messages, X, that Marie
Please hurry
You need to multiply the cost per text message by the number of messages (x) add that to the fixed charge.
The total of those need to be less than or equal to the amount she wants to spend.
The equation would be written as:
0.30x + 12 <= 40
