The solution of the equation 3 (x - 2) - 4 (x + 1) = -22 is,

⇒ x = 12

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

We have to given the function is,

3 (x - 2) - 4 (x + 1) = -22

Now, We can solve the expression as,

3 (x - 2) - 4 (x + 1) = -22

Use Multiplicative property;

3x - 6 - 4x - 4 = -22

Use addition and subtraction property,

- x - 10 = - 22

Use addition property and Add 22 both sides;

- x - 10 + 22 = - 22 + 22

- x + 12 = 0

Use subtraction property, Subtract 12 both sides;

- x + 12 - 12 = 0 - 12

- x = - 12

Multiply by -1 in both sides,

x = 12

Therefore, The solution of the equation 3 (x - 2) - 4 (x + 1) = -22 is,

⇒ x = 12

Find the value of UV
X=15 I think

Answers

Answer:

UV = 12

Step-by-step explanation:

SV = ST + TU + UV ( substitute values )

4x - 29 = 13 + 6 + 2x - 18

4x - 29 = 1 + 2x ( subtract 2x from both sides )

2x - 29 = 1 ( add 29 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15

Then

UV = 2x - 18 = 2(15) - 18 = 30 - 18 = 12

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.)

Answers

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

11. Twenty-four students in Jamal's class are wearing tennis shoes. There are
thirty students in his class. Jamal says that 70% of his class is wearing
tennis shoes. Is Jamal correct? Explain your reasoning.

Answers

no more then 70 percent is wearing tennis shoes

Answer: Incorrect.

Step-by-step explanation: 24 out of 30 is 80.00%.

Step 1: We make the assumption that 30 is 100 % since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100 % = 30.

Step 4: In the same vein, x % = 24 .

Step 5: This gives us a pair of simple equations:

100 % = 30(1).

x % = 24(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100 % / x % = 30/24

Step 7: Taking the inverse (or reciprocal) of both sides yields

x/100 = 24/30

x = 80 %

h(x) = ³√x - 3 write the inverse given the function

Answers

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.

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 )

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'?

Answers

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

      (x , y ) = (-y , x)

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)

Hence 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 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?

Answers

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.
