Answer:
(- 4, 2 )
Step-by-step explanation:
y = 3x + 14 → (1)
2x - 3y = - 14 → (2)
substitute y = 3x + 14 into (2)
2x - 3(3x + 14) = - 14 ← distribute parenthesis on left side and simplify
2x - 9x - 42 = - 14
- 7x - 42 = - 14 ( add 42 to both sides )
- 7x = 28 ( divide both sides by - 7 )
x = - 4
substitute x = - 4 into (1)
y = 3(- 4) + 14 = - 12 + 14 = 2
solution is (- 4, 2 )

When a patient with hypertension takes a particular type of blood pressure medication, the effects on the systolic pressure, S(t), can be measured by the following piecewise defined function: S of t is equal to the piecewise function of 140 minus 6 times t if 0 is less than or equal to t is less than or equal to 4 and 116 if 4 is less than t is less than 8 and 96 plus 8 times t if 8 is less than or equal to t is less than or equal to 12 where t is the time, in hours, since taking the medication. Based on the graph of the piecewise function, if the patient takes the blood pressure medication at 8 a.m., in which interval will their systolic pressure be lowest?
The interval where the systolic pressure will be lowest is from 12 PM to 2 PM.
What are the domain and ranges of a function ?
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.
A function S(t) is defined for systolic pressure.
S(t) = { 140 - 6t , for 0 ≤ t ≤ 4 }
S(t) = { 116 , for 4 < t < 8 }
S(t) = {96 + 8t , for 8 ≤ t ≤ 12 }
Let's find the values of systolic pressure [tex]S(t)_{min}[/tex] for each cases.
When , 0 ≤ t ≤ 4
[tex]S(t)_{min}[/tex] = 140 - ( 6 × 4 )
[tex]S(t)_{min}[/tex] = 140 - 24
[tex]S(t)_{min}[/tex] = 116
When , 4 < t < 8
[tex]S(t)_{min}[/tex] = 116
When , 8 ≤ t ≤ 12
[tex]S(t)_{min}[/tex] = 96 + ( 8 × 8)
[tex]S(t)_{min}[/tex] = 96 + 64
[tex]S(t)_{min}[/tex] = 160
So , the lowest value of S(t) will be 116 for for 4 < t < 8 and interval will be from 12 PM to 2 PM.
Therefore , the interval where the systolic pressure will be lowest is from 12 PM to 2 PM.

A repair company's charge for repairing a certain type of copy machine fits the model where y is the number of dollars charged and x is the number of minutes the repair person is on the job. how many minutes would it take for the cost of repair to reach $140? (round to the nearest minute.)
It will take 138 minutes for the repair cost to reach $140
Although part of your question is missing, you might be referring to this full question: A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 +0.617x. Where y is the number of dollars charged and x is the number of minutes the repair person is on the job. how many minutes would it take for the cost of repair to reach $140? (round to the nearest minute.)
As per the question:
Number of dollars charged by the company = y dollars
Number of minutes the repair person is on the job = x minutes
The cost that needs to be achieved = 140 dollars
Equation:
y = 47.38 + 0.617x------(1)
For the cost of repair to reach $140, substituting $140 in y in equation (1)
140 = 47.38 + 0.617x
Solving further and finding the value of x
140 - 47.38 = 0.617x
92.62 = 0.617x
x = 138 minutes (rounded to the nearest minute)
So, it will take 138 minutes for the repair cost to reach $140

A triangle contains vertices A (-3, 2), B (1, 2), and C (-4,-2).
If AABC is rotated 90° counterclockwise around the origin, what are the coordinates of the transformed figure AA'B'C'?
The coordinates of the triangle A'B'C' which is rotated 90° counterclockwise is A' (-2,-3) , B' (-2,1) , and C' (2,-4).
When the points are rotated 90° counterclockwise then the new coordinates will be transformed to

According to the question we have been the coordinates of the ΔABC which are :
A = (-3,2) , B = (1,2) and C = (-4,-2)
When the triangle is rotated 90° counterclockwise the new coordinates will become
A' = (-2,-3)
B' = (-2,1)
C' = (2,-4)

h(x) = ³√x - 3 write the inverse given the function
The inverse of the function h(x) = ³√x - 3 is h⁻¹(x) = (x + 3)³.
What is termed as the inverse of the function?An inverse function is one that reverses the action of another function. A function g has become the inverse of a function f when and only when y=f(x) and x=g (y). In other words, using f and then g is equivalent to doing nothing. This can be written as g(f(x))=x in terms of the combination of f and g.The given function is-
h(x) = ³√x - 3
Put y = h(x);
h(x) = y = ³√x - 3
Make x the subject;
x = (y + 3)³
Replace x with h⁻¹(y) = (y + 3)³
Restate with x instead of y.
h⁻¹(x) = (x + 3)³
Thus, the inverse of the function h(x) = ³√x - 3 is h⁻¹(x) = (x + 3)³.

If A,B, and C are the letters selected and we use A twice, B twice, and C once. The number of ways different passwords exist in this scenario are 30.
What is a password?
A password, sometimes known as a passcode (in devices made by Apple, for instance), is a hidden piece of information that is typically a long string of characters and is used to verify a user's identity. Passwords were always thought to be memorized, but today's average person has access to a huge number of password-protected services, making it difficult to remember a different password for each one. The secret is kept by a party known as the claimant, and the person confirming the claimant's identity is known as the verifier, according to the nomenclature of the NIST Digital Identity Guidelines. The verifier can determine the identity of the claimant when the claimant successfully uses a recognized authentication technique to show the verifier that they know the password.

4x - 29 = 1 + 2x ( subtract 2x from both sides )
2x - 29 = 1 ( add 29 to both sides )
2x = 30 ( divide both sides by 2 )
