Answer the point-slope form of the equation below that represents the line that passes through the point (6, -3) and has a slope of 1/2

A linear equation can have the form

y = mx + b

The slope is m

The point-slope form is

(y- y1) = m(x -x1) (1)

the point (x1, y1) = (6, -3)

______________

Replacing in (1) the slope and the point (x1, y1)

(y- y1) = m(x -x1)

(y- (-3)) = 1/2(x -6)

y+3 = 1/2(x-6)

__________________

So, checking the options the correct answer is C

A.) y-6 = 1/2(x+3)

B.) y = 1/2x - 6

C.) y+3 = 1/2(x-6)

D.) y-2y = 12

The equations that has the same value as x in 2/3(6x+12)=-24 are 4x+8 = -24 and 4x = -32 , option(a) and (e) are correct .

In the question ,

the equation 2/3(6x+12)=-24 is given

on solving for x ,we get

4x+8 = -24

4x = -24-8

4x = -32

x = -8 .

Solving option(a)

4x+8 = -24

4x = -24-8

4x = -32

x = -8

Solving for option(b)

9x+18 = -24

9x = -24-18

9x = -42

x = -42/9

solving for option(c)

4x = -16

x = -4

solving for option(d)

(18x+36)/2 = -24

18x + 36 = -48

18x = -48-36

18x = -84

x = -84/18

solving for option(e)

4x = -32

x = -32/4

x = -8

we can see that only option (a) and option(e) , given the value of x as -8 .

Therefore , the equations that has the same value as x in 2/3(6x+12)=-24 are 4x+8 = -24 and 4x = -32 , option(a) and (e) are correct .

The given question is incomplete , the complete question is

Which equation has the same value as X 2/3(6x+12)=-24 ?

Select two options

(a) 4x+8 = -24

(b) 9x+18 = -24

(c) 4x = -16

(d) (18x+36)/2 = -24

Solution:

Given the graph;

If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function.

ANSWER: B

Answer: 2

Step-by-step explanation:

The constant of proportionality is the same as the slope of the line. Using the slope formula with the points (0, 0) and (2, 4), [tex]\frac{4-0}{2-0}=2[/tex].

Slope intercept form:

y = mx + b

m = (y2 - y1)/(x2 - 1) = (-8 - 1)/(2 - (-1)) = -9/(2 + 1) = -9/3 = -3

m = -3

If we take one of the point, for example (2, -8) and use it on the equation with the slope we already found:

y = -3x + b

-8 = -3(2) + b

Solving for b:

-8 = -6 + b

b = -8 + 6 = -2

b = -2

Therefore, the equation is: y = -3x -2

Answer:

y = -3x -2

400 yards of fence = total fencing

400 = 2 widths + 2 heights

Since one side (width) is along the river, and the river bank acts as one side of the rectangle, the fence will be used in 3 sides:

400 = w+2h

Solving for h:

400-w=2h

(400-w)/2 = h

h= (400-w)/2 (a)

h= 200-1/2w (simplified)

To express the area:

Area of a rectangle : height x width

Since h = 200-1/2w

A = (200-1/2w) w

A = 200w-1/2w^2 (b)

The estimate (to one decimal place) of the average rate of change f is 2.3

The interval is given as

[-1, 2]

This can be rewritten as

x = -1 to x = 2

This can also be represented as

(a, b) = (-1, 2)

From the attached graph, we have

f(-1) = -5

f(2) = 2

The estimate (to one decimal place) of the average rate of change f is

Rate = [f(b) - f(a)]/[b - a]

This gives

Rate = [f(2) - f(-1)]/[2 + 1]

So, we have

Rate = [2 + 5]/[2 + 1]

Evaluate

Rate = 2.3

Hence, the average rate of change f is 2.3

QS = 20.7

To get length of side QS, we will consider triangle SQR (right angle triangle)

opposite (the side opposite the angle 28°) = QS

adjacent = base = 39

tan28 = QS/39

QS = 39 × tan28

QS = 39 × 0.5317

Powell believe that the inflation rate will be  4.46% over the next year .

In the question ,

it is given that

total return offered by the investment((nominal rate) = 17% = 0.17

return according to Powell Arms(real rate) = 12% = 0.12

let the inflation rate be x.

The inflation rate over the next year can be calculated using the formula .

(1+Real rate ) = (1+nominal rate )/ (1+ inflation rate )

Substituting the values , we get

(1+0.12) = (1+0.17)/(1+x)

1.12 = 1.17/(1+x)

1+x = 1.17/1.12

1 + x = 1.0446

x = 1.0466-1

x = 0.0446

x = 4.46%

Therefore , Powell believe that the inflation rate will be  4.46% over the next year .

Answer:

16.90≤19.78

Step-by-step explanation:

From the graph, the range of the function in the graph is; 0 ≤ M ≤ 6.5

The range of a function is the set of all possible output values for which the function still exists.

Now, from the graph, we can see that it is a linear graph that starts on the vertical axis with a coordinate of approximately (0, 1) which denotes 1 kg when the volume is 0 liters.

Now, we see that the line of the graph stops at the coordinate (7.5, 6.5) which denotes 6.5 kg when the volume is 7.5 liters.

Therefore the maximum mass is 6.5 kg while the minimum is 0 kg. Thus,;

Answer: Jenny = 6 | Kim = 7 | (Unknown Sister because no name) = 44

Step-by-step explanation:

Jenny = 6 years (that we already know)

6 x 2 = 12 - 5 = 7 years for Kim

7 + 6 = 13

To find the unknown age of the last sister, we will subtract 57 - 13 = 44

So the last sister is 44.

We are given the following function:

Part A. We are asked to draw the graph of the function. This is an exponential function with a negative sign, this means that the graph is reflected across the x-axis. Therefore, the graph is:

Part B. The domain of a function is the values that the fuction can take as an input. Since the function is an exponential function, it can take any value of "x" therefore, the domain is all the real numbers, we write this as follows:

Part B. The range of a function is the values that the function outputs, The range of an exponential function are the values that are greater than zero, but since the given function is reflected across the x-axis, this means that the rage is the negative real numbers, therefore, the range is:

Part D. For an exponential function of the form:

The asymptote is x-axis, since zero is never an output of the function. Therefore the equation of the asymptote is:

Part E. The y-intercept is the value of the function when "x = 0", therefore, substituting in the function we get:

Solving the operations:

Therefore, the y-intercept is -1

It should be noted that an exponent is used to express the numbers that are either too big or too small. This is usually expressed in their powers.

Fron the information, it as stated that a year is called "nice" if its number can be represented as the difference of two powers of two.

The next nice year will be the difference which will be

Let's talk a little about the simplest radical form of a square root

The first step to finding it is to write the number within the root as a product of prime powers, such product is called its integer factorization. Let's do that for 24:

Then, the integer factorization of 24 is

Thus,

The idea now is to take out of the root all we can. The rule is that we can only take out powers of 2 (for our root is a square root). In the expression

There is only one power of 2, within 2^3. We can write it as

How are we going to take out it? We are going to take out the base of the power, which is 2 in this case. Then,
