Find x if a = 13 and C = 47.
Answers
Answer:45.167
Step-by-step explanation:
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you don't have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)

The value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10
The equation is given as:
[tex]\frac 1x + \frac{1}{x + 18} = \frac{1}{40}[/tex]
Take the LCM
[tex]\frac{x + 18 + x}{x(x + 18)} = \frac{1}{40}[/tex]
This gives
[tex]\frac{2x + 18}{x(x + 18)} = \frac{1}{40}[/tex]
Cross multiply
[tex]40(2x + 18) =x(x + 18)[/tex]
Expand
[tex]80x + 720 =x^2 + 18x[/tex]
Collect like terms
[tex]x^2 + 18x - 80x -720 = 0[/tex]
[tex]x^2 - 62x -720 = 0[/tex]
Using a graphing calculator, we have:
[tex]x = 72\ or\ x =-10[/tex]
The value of x cannot be negative, because of the context.
So, the value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

x = -11 + 7y
5x + 2y = -18
Answers
Answer:
x = -4
y = 1
(-4,1)
Step-by-step explanation:
x = -11 +7y
5x + 2y = -18
This is a Substitution problem, so you put x = -11+7y into 5x+2y = -18
5(-11 +7y)+2y = -18
5(-11) = -55
5(+7y) = 35y
-55+35y+2y = -18
Now you add 35y and 2y which gives you 37y
-55+37y = -18
Now you add +55 from -55 and -18
37y = 37
You divide each side by 37 so that y = 1
Now you plug y(1) into the equation x = -11+7y
x = -11+7(1)
-11+7 = -4
x = -4

After becoming sick, a patient sees a doctor who determines the most likely cause is an allergic
reaction and prescribes an antihistamine. The patient returns home and stops burning candles and
incense for the next week while taking the medication. By the end of the week, the patient is feeling
better and is telling all his friends how wonderful the medication was at relieving his symptoms. This
is an example of
1. confounding, as there is no way to tell whether it was the medication that alleviated his
symptoms
2. convenience sampling since he only stopped burning candles and incense because it was easy
3.a double-blind experiment since neither he nor the doctor really knew what was wrong

6 x + 11 y = 29
x + 2 y = 5
Answers
Answer:
x = 3
y = 1
Step-by-step explanation:
x= 5-2y
6x + 11y = 29
6( 5 - 2y ) + 11y = 29
30 - 12y + 11 y = 29
-y = -1
y = 1
x + 2y = 5
x = 5 - 2y
x = 5 - 2

Answers
Answer:
A
Step-by-step explanation:
Inequality shows a relationship between two numbers or two expressions.
The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is
15 + 4m ≥ 35
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
His goal for this week is to run a minimum of 35 miles.
So far this week, he has already run 15 miles.
The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal.
15 + 4m ≥ 35
4m = number of m miles run in 4 days.
Thus,
The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is
15 + 4m ≥ 35

[tex]\frac{x+17}{x^2 +3} \geq 4[/tex]
Answers
(x + 17) / (x ² + 3) ≥ 4
x + 17 ≥ 4 (x ² + 3)
4x ² - x - 5 ≤ 0
(4x - 5) (x + 1) ≤ 0
The left side is equal to 0 when either
4x - 5 = 0 or x + 1 = 0
x = 5/4 or x = -1
For x < -1, we have both x + 1 < 0 and 4x - 5 < 0, so their product is positive and there are no solutions to the inequality in this interval.
For -1 < x < 5/4, we have x + 1 > 0 and 4x - 5 < 0, so their product is negative.
For x > 5/4, we have both x + 1 > 0 and 4x - 5 > 0, giving a positive product and thus no additional solutions.
The solution set is then the second interval, but including the endpoints since that makes the expression on the left equal to 0:
-1 ≤ x ≤ 5/4
