Identify the domain and range of the function graphed below

Answer:

Pretty sure it is A. y = -2x - 1

Step-by-step explanation:

y = mx + b

m is slope

b is y - intercept

y-intercept = point where line intercepts the y - axis. in this graph, it intercepts at (0, -1)

by counting the squares, you see this line has a rate of change of up two left one which is 2/-1 or -2. that is the slope

your photo is super blurry so it's hard to tell, but i'm 99% sure i am correct.

The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.

We need to find the slope-intercept equation of the line.

Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line.

The coordinates of the line (-1, 1) and (1, -3).

The slope of the equation is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Now, m=-3-1/1+1=-2

Substitute m=-2, x=-1 and y=1 in y=mx+b.

That is, 1=-2(-1)+b⇒b=-1

So, y=-2x-1

The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.

The average rate of change per year from 1 to 5 is 8inches

Step-by-step explanation:

Given

[tex]h=t^{2}+2t+10[/tex]

The average rate of change = [tex]\frac{h(5)-h(1)}{5-1}[/tex]

Now h(5)

[tex]\boxed{h(5)=-5^{2}+2(5)+10 }[/tex]

[tex]\boxed{h(5)=25+10+10}[/tex]

[tex]\boxed{h(5)=45}[/tex]

Now, h(1)

[tex]\boxed{h(1)=-1^{2}+2(1)+10}[/tex]

[tex]\boxed{h(1)=1+2+10}[/tex]

[tex]\boxed{h(1)=13}[/tex]

[tex]\boxed{Average~change~rate=\frac{h(5)-h(1)}{5-1} }[/tex]

[tex]\boxed{Average~change~rate=\frac{45-13}{5-1}=\frac{32}{4}=8 }[/tex]

The final answer

The average rate of change per year from 1 to 5 is 8 inches

Answer:

"one tail, alpha"

and

"negative"

Hello.

First, let's calculate

[tex]\tt{\displaystyle(\frac{7}{3}) ^{-3}[/tex]

Remember the Properties of Exponents:

If we have a number to a negative power, we flop the number over:

[tex]\tt{a^{-b}=\displaystyle\frac{1}{a^b}[/tex]

Now, let's use this property to simplify our expression.

Flop the number over:

[tex]\tt{\displaystyle(\frac{3}{7} )^3[/tex]

Now, we should recall another property of exponents:

[tex]\tt{\displaystyle(\frac{a}{b} )^m=\frac{a^m}{b^m}[/tex]

Since we have a fraction to a power, we should raise both the numerator and the denominator to the power:

[tex]\tt{\displaystyle\frac{3^3}{7^3}[/tex]

3 cubed is 9, and 7 cubed is 343:

[tex]\tt{\displaystyle\frac{9}{343}[/tex]

Now, the multiplicative inverse of that number is simply that number flopped over:

[tex]\Large\boxed{\tt{\displaystyle\frac{343}{9} }}[/tex]

I hope it helps.

Have a great day.

Hi there! I am EnjoyingLife, and I hope you find my answer helpful! :)

STEPS:

First we have a negative power so we flop the number over

Then since we have a fraction to a power we raise both the top & bottom to that power.

Then, we flop the number over once more to find the multiplicative inverse.

Answer:

40cm

Step-by-step explanation:

The formula to find the circumference is :

Here,

d ⇒ diameter

Given that,

Circumference = 125.6cm

Now let us find the diameter of the circle.

C = π × d

125.6 = 3.14 d

Divide both sides by 3.14.

40 cm = diameter

Answer:

Answer:

x3 − 2x + x3  ⇒ cubic

4x2 − 6x − 8x2  ⇒ quadratic

6x − 6 + 6x  ⇒ linear

5 + 4x2 − 4x2 + 5  ⇒ constant

Step-by-step explanation:

For the other question its

Classify each polynomial as a monomial, binomial, or trinomial. Combine like terms first.

x3 + 3x3 + 2x  ⇒ binomial

2x3 + 5x + 3x4 − x  ⇒ trinomial

4x − 5x + x − 2  ⇒ monomial

6x2 + 5 − 2x2 − 9  ⇒ binomial

The answer is: (x-3)(x-1)(x+2)

Because the first term is x^3, it means that there must be 3 independent x's multiplying by each other. From there you just have to est what numbers to pair them with. If that doesn't make sense let me explain more:If you have x^2 it will be:(x + y) (x + z) If you have x^3 it will be: (x + y) (x + z) (x + g) If you have x^4 it will be: (x + y) (x + z) (x + g) (x + f) etc; now all you have to do after you pick which one it matches with, it just find what the value of y, z, and g are through trial and error. I am not showing all my trial and error because it is long to type out, easier to just explain the process.

Answer:

PV= $5,483.45

Step-by-step explanation:

Giving the following information:

Semiannual deposit= $450

i= 0.068/2= 0.034

Number of periods= 8*2= 16

First, we need to calculate the future value using the following formula:

FV= {A*[(1+i)^n-1]}/i

A= semiannual deposit

FV= {450*[(1.034^16) - 1]} / 0.034

FV= $9,362.30

Now, we can calculate the present value:

PV= FV/(1+i)^n

PV= 9,362.30 / 1.034^16

PV= $5,483.45

Answer:

y = 1/2x-5

Explanation:

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and  b is the y-intercept

All you really have to do here is  replace m with 1/2, which is the slope you gave, and  replace b with -5, the y-intercept you gave,  in the equation y=mx+b. And you will get y = 1/2x-5

Volume of the figure = volume of triangular prism + volume of trapezoidal prism = 497 m³.

Volume of any prism = Base area × height of the prism

Thus:

Volume of the figure = volume of triangular prism + volume of trapezoidal prism

Volume of triangular prism = 1/2(b×h)×L = 1/2(8 × 4) × 14

Volume of triangular prism = 224 m³

Volume of trapezoidal prism = 1/2(b1+b2)×h×L = 1/2(8 + 5) × 3 × 14

Volume of trapezoidal prism = 273 m³

Volume of the figure = 224 + 273 = 497 m³.

Answer:

y = -2x -4

Step-by-step explanation:

The equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept.  We are told that the slope of the line is -2, so we can start with

y = mx + b

y = -2x + b

We can figure out the value of b by plugging in the coordinates of the point given (-2, 0)

0 = -2(-2) + b

0 = 4 + b

Subtract 4 from both sides of the equation

-4 = b

Then plug that value of b back into the equation above:

y = -2x + (-4) or y = -2x -4

Answer:

y=mx+c

we will find c

0=(-2)(-2)+c

c=-4

y=-2x+(-4)

y=-2x-4
