Which expression is equivalent to
2x^2+2x-4/2x^2-4x+2

Answers

Answer: A is correct (x+2)/(x-1)

Step-by-step explanation:

Divide the top and bottom by 2, to simplify

[2(x^2+x-2)]/[2(x^2+2x+1)]

The 2's cancel each other out, since 2/2 would be 1.

Now factor (x^2+x-2)/(x^2+2x+1)

[(x+2)(x-1)]/[(x-1)(x-1)]

Now you can cancel out one of the (x-1) on top and bottom. All that's left is (x+2)/(x-1) which is your answer. Hope this helps!

what is the Distance between (-4, -8) and (10, -8)??

Answers

Answer:

The distance between both points would be 14.

Step-by-step explanation:

The y coordinate or -8 stays the same for both points on a coordinate grid. However the x coordinate changes from -4 to 10, which is 14 places away on a coordinate grid. Therefore the distance between these two points is 14.

Answer:

14

Step-by-step explanation:

Use the distance equation:

d² = (x₂ − x₁)² + (y₂ − y₁)²

d² = (10 − -4)² + (-8 − -8)²

d² = 14² + 0²

d = 14


Solve the following system of equations using the substitution method
y = 4/5x - 3
y = -7

Answers

Answer: [tex]x=-5\\y=-7[/tex]

Step-by-step explanation:

Given the system of equations:

[tex]\left \{ {{y=\frac{4}{5}x-3 } \atop {y=-7}} \right.[/tex]

You can apply the Substitution method.

You need to substitute the second equation which gives the value of the variable "y" into the first equation and solve for the variable "x", then:

[tex]y=\frac{4}{5}x-3\\\\-7=\frac{4}{5}x-3\\\\-7+3=\frac{4}{5}x\\\\-4=\frac{4}{5}x\\\\(-4)(5)=4x\\\\x=\frac{-20}{4}\\\\x=-5[/tex]

Which is a quadratic function having a leading coefficient of 3 and a constant term of –12? f(x) = –12x2 + 3x + 1 f(x) = 3x2 + 11x – 12 f(x) = 12x2 + 3x + 3 f(x) = 3x – 12

Answers

For this case we have that a quadratic equation is of the form:[tex]ax ^ 2 + bx + c = 0[/tex]

Where:

a: is the main coefficient because it accompanies the quadratic variable.

b: It is the linear coefficient

c: It is the constant term.

Then, a quadratic function with a main coefficient of "3" and a constant term of "-12" is:

What equation represents an exponential function that passes through the point (2, 80)?


Answers

Answer:

[tex]f(x) = (4\sqrt{5})^{x}[/tex]

Step-by-step explanation:

The exponential function looks like the following: [tex]f(x) = b^{x}[/tex].

If the function passes through the point (2, 80), then:

[tex]f(x) = b^{x}[/tex] → [tex]80 = b^{2}[/tex]

Solving for 'b':

[tex]b = \sqrt{80}[/tex] →[tex]b=4\sqrt{5}[/tex]

Then, the equation of exponential function that passes through the point (2, 80) is: [tex]f(x) = (4\sqrt{5})^{x}[/tex]

Step-by-step explanation:

Given the equation y= -2.5x + 222.5, where 'x' is the time spent exercising in minutes. If we want to know the amount of cholesteron for a person exercising 20 minutes a day, we just have to subtitute 20 into the equation for x.

An exercise cube measures 27 in. on each side. What is its volume? a. 22, 785 in3 c. 18,659 in3 b. 19,683 in3 d. 17, 257 in3

Answers

Answer:

your answer is 19,683 in^3

Step-by-step explanation:

i don't know what the heck an exercise cube is, but hey, it's the world of real world problems

volume of a cube = side length ^ 3

= 27*27*27

=19,683 in^3

If the side of cube is 27 inches then the volume of cube is 19683 [tex]inches^{3}[/tex].

What is volume?

The volume is the amount of substance a container can hold in its capacity. Substance can be liquid or solid. Volume of cube is side*side*side which can be written as [tex]side^{3}[/tex].

How to calculate volume?

We have been given that the side of cube is 27 inches and we are required to find the volume of cube.

Volume=[tex]side^{3}[/tex]

Putting side=27.

Volume=[tex](27)^{3}[/tex]

=19683 cubic inches.

Hence if the side of cube is 27 inches then the volume of cube is 19683 [tex]inches^{3}[/tex].

D.

Answers

Answer:

A.

Only function g is even

Answer:

Option: A is the correct answer.

  A.   Only function g is even.

Step-by-step explanation:We know that the graph of a even function is such that both the ends of a graph points in the same direction and the graph of a odd function is such that both the ends of the graph points in the opposite direction.Also, the graph of the even function is symmetric about the y-axis .whereas the graph of the odd function is symmetric about the origin i.e. it has rotational symmetry about the origin.

Here by looking at the graph we observe that the graph of function g satisfies the condition of even function.

( whereas the graph of function f is not symmetric about the y-axis and hence function f is not even )

     Hence,  the function g is an even function.

Wayne needs to drive 470 miles to reach Milwaukee. Suppose he drives at a constant speed of 50 miles per hour. Which function represents Wayne’s distance in miles from Milwaukee in terms of the number of hours he drives?
A.

B.
y = 470 + 50x
C.
y = 50 − 470x
D.
y = 50 + 470x
E.
y = 470 − 50x

Answers

Let the number of hours driven equal x.

You would multiply the number of hours by his speed, so you would have 50x

You would then want to subtract that from the total miles to see how many more miles he needs to drive.

Answers

Answer:

y+5 = -3(x-1)  point slope form

y = -3x-2 slope intercept form

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/ (x2-x1)

m = (7--5)/(-3-1)

   = (7+5)/(-3-1)

   = 12/-4

   = -3

The slope is -3

Then we can use point slope form to write an equation

y-y1 = m(x-x1)

y--5 = -3(x-1)

y+5 = -3(x-1)

This is in point slope form

Distribute

y+5 = -3x+3

Subtract 5 from each side

y+5-5 = -3x +3-5

y = -3x-2

This is in slope intercept form

1. 7(2)^t

2. 3000(0.93)^t

3. 300(1.015)^t

4. 300(0.985)^t

Answer with explanation:

We know that the exponential function is given by:

             [tex]f(x)=ab^x[/tex]

where a is the initial amount.

and b is the change in the amount and is given by:

[tex]b=1+r[/tex] if the function is increasing by a rate of r

and [tex]b=1-r[/tex] if the function is decreasing by a rate of r.

a)

The initial amount of fish in the trout are: 7

i.e. a=7

Also, the population doubles every year.

This means that that b=2

Hence, the population after t years is given by the function P(t) as:

[tex]P(t)=7(2)^t[/tex]

b)

The original amount of the machine is: $ 3,000

i.e. a=3,000

Also, the value of machine decreases by a rate of 7%

i.e.

[tex]r=7\%\\\\i.e.\\\\r=0.07[/tex]

Hence, we have:

[tex]b=1-r\\\\i.e\\\\b=1-0.07\\\\i.e.\\\\b=0.93[/tex]

Hence, the function which represent the price of the machine after t years i.e. P(t) is given by:

[tex]P(t)=3000(0.93)^t[/tex]

c)

The initial population of colony of ants i.e. a=300.

The number of ants increases at a rate of 1.5% every month.

i.e. [tex]r=1.5%\\\\i.e.\\\\r=0.015[/tex]

i.e.

[tex]b=1+r\\\\i.e.\\\\b=1+0.015\\\\i.e.\\\\b=1.015[/tex]

Hence, the function P(t) which represents the population of ants after t months is given by:

[tex]P(t)=300(1.015)^t[/tex]

d)

The initial infected cells i.e. a=300

The infected cells are decaying at a rate of 1.5% per minute.

i.e.

[tex]r=1.5%\\\\i.e.\\\\r=0.015[/tex]

Since, there is a decay hence,

[tex]b=1-r\\\\i.e.\\\\b=1-0.015\\\\i.e.\\\\b=0.985[/tex]

Hence, the function P(t) which represents the number of infected cells after t minutes is given by:

[tex]P(t)=300(0.985)^t[/tex]
