Fill in the missing work and justification for step 3 when solving 2(x + 1) = 10

Answer:

c = 2

Step-by-step explanation:

To solve this equation, you need to combine like terms and then divide by the coefficient of the variable on both sides of the equation.

To start, add 12c and 6c because they are like terms.

12c + 6c = 18c

Then, divide by 18 on both sides of the equation to solve for c.

18c = 36

c = 2

Step-by-step explanation:

(A) To find inverse of f(x) = y = 1 / x - 3 :

Transform in terms of x

y = 1 / x - 3

x - 3 = 1 / y

x = 3 + 1 / y

Exchange x with y :

[tex] {f}^{ - 1} (x) = 3 + \frac{1}{x} [/tex]

Therefore, g(x) is not inverse of f(x) and vice versa.

(B)

Domain of f(x) = R - {3}

Domain of g(x) = R - {0}

3n-5

Answer;

m<EAD=29°

m<CAB=119°

Step-by-step explanation:

Angles on a straight line sum up to 180°

This implies that,

61°+90°+EAD=180°

151°+EAD=180°

Subtracting 151° from both sides,we obtain,

EAD=180°-151°

EAD=29°

Angles on a straight line add up to 180°.

this implies that,

CAB+61°=180°

Subtracting 61° from both sides,we obtain

CAB=180°-61°

CAB=119°

Thus,m<EAD=29° and m<CAB=119°

Answer:

29° and 119°

Step-by-step explanation:

Since CF is a straight line, then

90° + ∠ EAD + 61° = 180°, that is

∠ EAD + 151° = 180°  ( subtract 151° from both sides )

∠ EAD = 29°

and

∠ CAB + 61° = 180° ( subtract 61° from both sides )

∠ CAB = 119°

Answer:

Jeff is faster

Step-by-step explanation:

kilometers are faster than meters

and 7 kilometers is 700 meters

so 100 meters isn't fast enough compared to Jeff's speed

Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.

The average speed of a body is the ratio of the distance covered by the body to the time it takes to cover that distance.

In the question, we are given that Jeff says that he can run 7 kilometers per hour while Cameron says that he can run 100 meters per minute.

We are asked to tell who is the faster among them.

We need to know that, 1 kilometer = 1000 meters, and 1 hour = 60 minutes.

Jeff's average speed = 7 km/hr. = 7km/1hr = (7*1000) m / (1*60) min

or, Jeff's average speed = 7000/60 meters per minute = 116.67 meters per minute.

We are given that Cameron's average speed is 100 meters per minute.

So, we can say that Jeff is faster than Cameron, as

Jeff's average speed > Cameron's average speed.

∴ Jeff is faster than Cameron as his average speed is more than that of Cameron's average speed.

Answer:

4 minutes

Step-by-step explanation:

Given that:

Person 1's speed = 4 meters per minute

Anthony's speed = 4.5 meters per minute

To find:

In how many minutes, Anthony will be 2 meters ahead ?

Solution:

Let the time taken = [tex]t[/tex] minutes

Distance covered by 1st person = D meters

Distance covered by Anthony = (D + 2) meters

Formula:

Distance = Speed [tex]\times[/tex] Time

For 1st person:

[tex]D = 4 \times t[/tex] ....... (1)

For Anthony:

[tex]D+2 = 4.5 \times t[/tex]

Using first equation:

[tex]4t + 2 = 4.5t\\\Rightarrow 0.5t = 2\\\Rightarrow \bold{t = 4\ minutes}[/tex]

So, in 4 minutes, Anthony will be 2 meters ahead of the first person.

A. To find the area of a circle you need to use the formula A= π r²  

The radius (R) is half of the diameter . . . that's 6.5 cm .

r² = ( 6.5)² = 42.25 cm²

Area =  π r² = 42.25 π  =  132.7 cm²

B. Area of a rectangle is just (length) x (width).

Length = 12 cm

Width = 5 cm

Area = (12 cm) x (5 cm) = 60 cm²

C. The shaded portion is the part of the circle that's NOT in the rectangle. So its area is (area of the circle) - (area of the rectangle)

Area = (132.7 cm²) - (60 cm²) = 72.7 cm²

Step-by-step explanation:

In word problem, it is solved by 2k+1, among the most common forms of even an, unlike number.

Let another odd integer become 2k+1.....(a)

(2K+1)+(2k+3)+(2k+5)=(2k+7)+(2k+9)+3(to take the left side 3 extra)  

Quality for the k:

[tex]\to 6k+ 9 = 4k +19 \\\\\ \to 6k-4k= 19+9 \\\\ \to 2k = 10 \\\\ \to k = \frac{10}{2}\\\\ \to K = 5[/tex]

put the value of k, in the equation (a):

[tex]\to 2k+1 \\ \to 2(5)+ 1 \\ \to 10 + 1\\\to 11\\[/tex]

======================================================

Explanation:

The given equation is y = (-3/4)x - 2. Comparing it to y = mx+b, the slope is m = -3/4

Flip the fraction and the sign to go from -3/4 to 4/3. This is the perpendicular slope. Multiplying the two slopes gets (-3/4)*(4/3) = -1.

Rule: the original slope and perpendicular slope always multiply to -1, assuming neither line is vertical or horizontal.

We'll use the point (x,y) = (3,6) and the perpendicular slope m = 4/3 to find the y intercept b

y = mx+b

6 = (4/3)(3) + b

6 = 4+b

6-4 = b

2 = b

b = 2

The y = mx+b equation becomes y = (4/3)x + 2 which is the slope intercept form of the perpendicular line.

--------------

Extra info:

If you want to convert to standard form Ax+By = C, then you could do the following steps

y = (4/3)x + 2

3y = 4x + 6 ... multiply everything by 3 to clear out the fraction

3y - 4x = 6

-4x + 3y = 6

4x - 3y = -6 ... multiplying both sides by -1; this is to make A > 0
