How do I know they are similar.

Answer: A. It would be shifted up.

Step-by-step explanation: the only thing that is changing in the two equations is the last number. The last number is not there in the second equation because the y-intercept is 0. The y-intercept in the first equation is -2 and shifts up 2 to y-intercept if 0. Therefore, your answer would be A. It would shift up.

The graph of the new equation compared with the original graph is the new graph would be shifted up.

Option A is the correct answer.

We have,

If the equation y = 12x - 2 were changed to y = 12x, the graph of the new function would be different from the original.

The original equation y = 12x - 2 represents a linear function with a slope of 12 and a y-intercept of -2.

The graph of this equation would be a straight line that is steep (with a slope of 12) and shifted downward by 2 units (due to the y-intercept of -2).

However, if we change the equation to y = 12x, the new equation represents a linear function with the same slope of 12 but with no y-intercept (it passes through the origin).

The graph of this equation would still be a straight line, but it would be shifted up compared to the original equation since the y-intercept has been removed.

Therefore,

It would be shifted up.

Answer:

A and D

Step-by-step explanation:

The remainder after division is 8, that is the 8 at the end of 2 - 4 8

Given f(x) divided by (x + h)

Then if (x + h) is a factor the remainder = 0

Hence (x + 7) is not a factor since remainder is 8

and f(- h) = remainder

that is f(- 7) = 8 → D

A and D are the correct statements.

In option  A f(-7) is the remainder which gives the value 8.

So, option A is correct.

When we put x = 7 in the function it is coming 99

So, option B and C are wrong.

Slope formula: y2-y1/x2-x1

Plug in: -15-0/-11-3 = -15/-14 = 15/14 = slope

For this case we have by definition, the slope of a line can be found by the following formula:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]

Two points are needed through which the line passes.

According to the data we have:

[tex](x_ {1}, y_ {1}) :( 3,0)\\(x_ {2}, y_ {2}): (- 11, -15)[/tex]

Substituting we have:

[tex]m = \frac {-15-0} {- 11-3} = \frac {-15} {- 14} = \frac {15} {14}[/tex]

Changing from y = -3x + 5 to y = 2x + 5 would make the slope steeper.

The slope of the new graph would become steeper.

When changing from y = -3x + 5 to y = 2x + 5, the original slope of -3 increases to 2, making the new graph steeper.

Therefore, the correct answer is D. The slope of the new graph would become steeper.

ANSWER

The common ratio is -3.

EXPLANATION

In general, the common ratio of a Geometric Sequence is given by:

[tex] r = \frac{a_{n+1}}{a_{n}} [/tex]

We can find the common ratio using any two consecutive terms of the geometric sequence by dividing the subsequent term by the previous term.

The given sequence is -2,6,-18,54

Using the first two terms the common ratio is

[tex]r = \frac{6}{ - 2} = - 3[/tex]

We could also used the second and third terms to get

[tex]r = \frac{ - 18}{6} = - 3[/tex]

and so on and so forth.

Therefore the common ratio is -3.

The graph at option 4 represents the given equation y = -4x - 3 correctly. This is obtained by calculating the slope and finding the y-intercept.

The slope of a line given by

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

The ratio of the difference between y-coordinates of two points on the line to the difference of their x coordinates.

The equation is y = -4x - 3

On comparing the equation with the slope-intercept form y = mx + c,

m = -4 and y-intercept c = -3.

Since the y-intercept is -3, the graphs at options 1 and 2 do not represent this equation. So, the remaining graphs may represent the given equation.

The graph at option 3 has a line with two points (2, 5) and (0, -3)

So, the slope is

m = [tex]\frac{-3-5}{0-2}[/tex]

   = 4

Thus, it is not the same as the slope of the given equation.

The graph at option 4 has a line with two points (-2, 5) and (0, -3)

So, the slope is

m = [tex]\frac{-3-5}{0+2}[/tex]

   = -4

Thus, the line shown in the graph at option 4 has a slope of -4 and the y-intercept is -3. These are the same as the given equation. So, option 4 is correct.

Therefore, the graph at option 4 is the correct representation of the given equation.

Jim, please use the symbol " ^ " to indicate exponentiation:

y = x^3 + 3x^2 – x – 3.  Thanks.

A "turning point" is a point on the graph of a function at which the derivative changes sign (e. g., from positive to negative or vice versa).  To identify turning points, we differentiate the given function twice, set the second derivative equal to zero and identify the x-values at which the sign of the derivative changes.

Given y = x^3 + 3x^2 – x – 3,

          dy/dx = 3x^2 + 6x - 1

           d²y

          ------ = 6x + 6            and this is zero at x = -1.

           dx²

We can easily show that the 2nd derivative changes sign at x = -1.

Thus, the only turning point here is (-1, [-1]³ + 3[-1]² - [-1] - 3), or (-1, 0).

You already have the current, but not the voltage.  

But you are given resistance, and you know that  

Voltage=Current*Resistance  

Therefore  

V=I*R=4*12=48V  

So you have 48V  

Now you can figure out the Power  

P=I*V=4*48=192W  

Therefore you have 192W.

hope this helps

The total power in a circuit is 192W.

Power exists at the time rate of excess or absorbing energy. The power delivered or absorbed by an element exists as the product of the current flowing through the component and the voltage across the element. Power exists estimated in watts. If the power exists positive then it exists absorbed by the component and if it exists negative then it is supplied by the element.

Power = Current [tex]*[/tex] Voltage

We have the current, but not the voltage.

But you are given resistance, and you know that

Voltage = Current [tex]*[/tex] Resistance

Therefore,

[tex]V=I*R=4*12=48V[/tex]

To find the area of a rhombus, multiply the two diagonals together then divide by 2.

Area = 20 *15 = 300 / 2 = 150 sq. units.

Answer:

y - 1/3 = 3/4(x - 4)

Step-by-step explanation:

We know that the general equation of a line is the following:

y - yo = m(x-xo), where 'm' represents the slope of the line, and (xo, yo) is any point that belongs to the line.

Then, the equation of the line that passes through (4, 1/3) and has a slope of 3/4 is: y - 1/3 = 3/4(x - 4)

For this case we have that by definition, the slope-intersection equation of a line is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut point with the y axis.

They tell us as data that:

[tex]m = \frac {3} {4}[/tex]

Now the equation is:

[tex]y = \frac {3} {4} x + b[/tex]

We substitute the point to find "b":

[tex](4, \frac {1} {3})[/tex]

[tex]\frac {1} {3} = \frac {3} {4} (4) + b[/tex]

[tex]b = \frac {1} {3} -3\\b = - \frac {8} {3}[/tex]

Finally the equation is:

[tex]y = \frac {3} {4}x - \frac {8} {3}[/tex]

In point-slope form the equation is:

[tex]y- \frac {1} {3} = \frac {3} {4} (x-4)[/tex]

Answer:

At x=-2, y=16

At x=0, y=1

At x=3, y=1/64

Step-by-step explanation:

As we know that the function is given by:

[tex]y=(\frac{1}{4})^{x}[/tex]

The table represents the output values on given inputs.

So, when the input is -2:

[tex]y=(\frac{1}{4} )^{-2}\\y= \frac{(1)^{-2}}{(4)^{-2}}[/tex]

To convert the power in positive:

[tex]y=\frac{(4)^{2}}{(1)^{2} }\\y=16[/tex]

So the output for x=-2 is 16.

For x=0

[tex]y=(\frac{1}{4})^{0}[/tex]

Anything whose exponent is zero equals to 1, so y=1

For x=3, output is incomplete.

To complete,

[tex]y=(\frac{1}{4})^{3}\\y=\frac{(1)^{2} }{(4)^{2} }\\y=\frac{1}{64}[/tex] ..
