Answer:

A. 2x + (-x + 2) = -1

Step-by-step explanation:

Well if we use x + y = 2 as the substitute we need to solve for y.

x + y = 2

-x to both sides

y = -x + 2

Substitute

2x + (-x + 2) = -1

Thus,

the answer is A. 2x + (-x + 2) = -1.

Answer:

a) Point (42, 30,000)

b) The salaries are directly proportional to the age of a surgeon to a large extent

c) By performing regression analysis

Step-by-step explanation:

a) From the given information;

Given that Igor is an experienced surgeon that just completed his medical training, Igor has;

1) Years of experience

2) Redid his medical training to obtain the same qualification with more time spent

3) Able to work only with his newly acquired re-qualification

Therefore, Igor will receive wages similar to other recently trained surgeons that have similar years of experience post Igor's re-qualification

The point that most likely will represent Igor's data will have his years of experience and wage commensurate with his UK based post qualification experience, which is the point (42, 30,000)

b) Because from the graph apart from the two points, (that of Igor and (34, 44,000)), the salaries of the other points vary proportionately with the age of the Surgeon

c) By carrying out a regression analysis as follows;

A = 50, 55,000

B = 42, 46,000

C = 38, 42,000

D = 34, 44,000

E = 42, 30,000

F = 26, 30,000

G = 22, 28,000

Analyzing the above data using excel regression analysis gives Which gives

R² = 0.5739 which shows that approximately 60% of the data fit the Managing Directors data

The equation is as follows;

y = 790·x + 10620

Where

y = Salary

x = Age of surgeon.

Answer:

180

Step-by-step explanation:

Using the ratio flats : bungalows = 10 : 3

Given there are 30 bungalows then dividing by 3 gives the value of one part of the ratio.

30 ÷ 3 = 10 ← value of 1 part of the ratio, thus

10 parts = 10 × 10 = 100 ← number of flats

Using the ratio houses : flats = 9 : 5

The number of flats = 100 thus dividing by 5 gives

100 ÷ 5 = 20 ← value of 1 part of the ratio, thus

9 parts = 9 × 20 = 180 ← number of houses

[tex]w = \left(1+\frac{1}{6} \right)\cdot v[/tex]

Donde:

[tex]z[/tex] - Monto inicial, medido en soles peruanos.

[tex]u[/tex], [tex]v[/tex], [tex]w[/tex] - Montos remanentes después de ganancias, medidos en soles peruanos. (Donde w es el monto final).

Se reduce el sistema de ecuaciones:

[tex]w = \left(1+\frac{1}{2} \right)\cdot \left(1+\frac{1}{4} \right)\cdot \left(1+\frac{1}{6} \right)\cdot z[/tex]

[tex]w = \frac{35}{16}\cdot z[/tex]

Si [tex]w = 70[/tex], el monto inicial es:

[tex]z = \frac{16}{35}\cdot w[/tex]

[tex]z = \frac{16}{35} \cdot (70)[/tex]

[tex]z = 32[/tex]

Ahora,

[tex]x = \frac{5}{2} \cdot z[/tex]

[tex]x = \frac{5}{2}\cdot (32)[/tex]

[tex]x = 80[/tex]

Answer:

true

Step-by-step explanation:

because CD divided AB into equal halves, so they are of course perpendicular.

Answer:

Step-by-step explanation:

This is definitely true. AC is congruent to BD, and by the Isosceles Triangle Theorem, if this congruency is true, then the angles across from these congruent sides are also congruent. This means that angle ACD is congruent to angle BCD. That makes CD a bisector of angle ACB; it also makes CD a bisector of side AB. The definition of a perpendicular bisector is that the segment splits its angle in half (and it does) and that it splits the side it goes through in half (which it does). This makes CD, in a nutshell, the perpendicular bisector of AB (which also means that CD is perpendicular to AB).

Answer:

f(10) = 38

Step-by-step explanation:

Notice that this sequence is given in recurrent form, so you need to know the previous term in order to calculate the following one. Then let's get into all the 10 terms needed:

f(1) = 2

f(2) = 2 + 4 = 6

f(3) = 6 + 4 = 10

f(4) = 10 + 4 = 14

f(5) = 14 + 4 = 18

f(6) = 18 + 4 = 22

f(7) = 22 + 4 = 26

f(8) = 26 + 4 = 30

f(9) = 30 + 4 = 34

f(10) = 34 + 4 = 38

Answer:

x = 3, x = 4

Step-by-step explanation:

Given

x³ - 2x² - 11x + 12 = x³ - 13x - 12

Subtract x³ - 13x - 12 from both sides

- 2x² + 2x + 24 = 0 ← in standard form ( divide all terms by - 2 )

x² - x - 12 = 0

(x - 4)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 3 = 0 ⇒ x = 3

Answer:

262.44 cubic metres.

Step-by-step explanation:

First, we can calculate the volume of the cylinder by doing pi * r^2 * h. In this case, r is 5 / 2 and h is 7.

pi * (5/2)^2 * 7 = pi * 25/4 * 7 = pi * 6.25 * 7 = pi * 43.75 = 3.14159265 * 43.75 = 137.4446784 cubic m.

Seconds, we calculate the volume of the cube. It is 5^3 = 5 * 5 * 5 = 25 * 5 = 125 cubic m.

137.4446784 + 125 = 262.4446784, which is about 262.44 cubic metres.

Hope this helps!

Answer:

26.75 units ^2

Step-by-step explanation:

Since the shape is complex, divide it into 3 right angled triangles and one square. Find the area of these individual shapes first, then fin the sum of these area to calculate the ultimate area of e complex shape:

Triangle 1 = 1/2 x 2 x 5 = 5 units ^2

Triangle 2 = 1/2 x 2 x 2 = 2 units ^2

Triangle 3 = 1/2 x 3.5 x 9 = 15.75 units ^2

Square = 2 x 2 = 4 units squared.

Now add all these up 15.75 + 2 + 5 + 4 = 26.75 units squared.

Answer:

From TM = MS, MS = MR, and TM = MR

QT = TM = MR Transitive property

Step-by-step explanation:

ΔPQR is an equilateral triangle Given

∠PQR = ∠RPQ = ∠PRQ = 60° Definition of equilateral triangle

∠PQR = ∠SQT + ∠SQP = 60° Addition property of angles

∠PRQ = ∠SRM + ∠SRP = 60° Addition property of angles

In triangle PQR, ∠SQT = ∠SQP = 30° = ∠SRM = ∠SRP Angles bisected by angle bisector

∠STM = ∠PQR - 60° Angle of same side of two parallel lines crossing the same transversal

∠PRQ = ∠SMT = 60° Angle of same side of two parallel lines crossing the same transversal

∠MST = 180 - ∠SMT - ∠STM = 180 - 60 - 60 = 60°

∠MST = ∠SMT = ∠STM = 60°, ΔMST is an equilateral triangle, all angles equal

ST = MS = TM definition of equilateral triangle

∠STQ = 180 - ∠STM = 180° - 60° = 120° (∠STQ and ∠STM are supplementary angles)

∠QST = 180 - ∠SQT - ∠STQ = 180 - 30 - 120 = 30 (Interior angles in the same triangle)

ΔQTS is an  isosceles triangle, base angles are equal

∴ ST = QT Definition of equilateral triangle

Similarly

∠SMR = 180 - ∠SMT = 180° - 60° = 120° ∠SMR and ∠SMT are supplementary angles

∠MSR = 180 - ∠SRM - ∠SMR = 180 - 30 - 120 = 30 (Angles in the same triangle)

ΔRMS is an  isosceles triangle, base angles are equal

∴ MS = MR Definition of equilateral triangle

Since ST = QT, and,  ST = TM, QT = TM Transitive property

Also since TM = MS, and MS = MR, TM = MR Transitive property

Therefore;

QT = TM = MR Transitive property

Answer:

The hourly charge is $4 per hour for the first 3 hours.

The rate then drops to $2 per hour until the end of the 6th hour.  

The hourly rate drops further to $1 per hour between the 6th and 10th  hours.

The maximum price of the bike rental is $30.

Step-by-step explanation:

The slope of the graph corresponds to the hourly rate for the bike rental.

During the first three hours of the bike rental, the price increases by $4 each hour.

Between the 3rd  and 6 th hours, the slope of the graph is 2, which means the hourly rate of the bike rental is $2 per hour.

Between the 6th and 10th hours, the rate is $1 per hour.

After the 10th  hour, the price, P, stops increasing. The maximum price of the bike rental is $30.
