Answer:

x=35

y=34

Step-by-step explanation:

x+y=-1

x+3y=67

x=-3y+67

-3y+67+y=-1

-2y+67=-1

-2y=-68

y=34

x=-35

Answer:

-3x^3+x

Step-by-step explanation:

Let's first write the expression:

-3x+x^3-2x^2-(4x^3-2x^2-4x)

Now we can simplify. Be sure to remember to distribute the "-" to all the numbers in the parentheses. You can picture it like multiply "-1" to all the numbers in the parentheses to make it easier.

-3x+x^3-2x^2-4x^3+2x^2+4x

Now we combine like terms.

x-3x^3

Write the polynomials by decreasing exponents

-3x^3+x

The domain of the function is [0.70, 2.55]

  • The range is [1.04, 2.56]
  • The domain is the set of x values and the range is the set of y values

<h3>How to determine the domain of the function?</h3>

From the question, we have the following parameters that can be used in our computation:

(0.70)(1.04)(1.15)(1.38)(1.86)(1.70)(2.55)(1.29)(2.22)(2.56)

When represented as a table, we have:

x            y

0.70    1.04

1.15      1.38

1.86     1.70

2.55     1.29

2.22    2.56

Remove the y values

So, we have

x = {0.70, 1.15, 1.86, 2.55, 2.22}

As an interval notation, we have: [0.70, 2.55]

This set of values is the domain

<h3>How to determine the range of the function?</h3>

In (a), we have the following table of values

x            y

0.70    1.04

1.15      1.38

1.86     1.70

2.55     1.29

2.22    2.56

Remove the x values

So, we have

y = {1.04, 1.38, 1.70, 1.29, 2.56}

As an interval notation, we have: [1.04, 2.56]

This set of values is the range

<h3>How the domain and the range are calculated</h3>

To determine the domain, we make use of the x values

While the y values are used to represent the range

Help pls (20 points it’s a lot please)
irga5000 [103]

Answer:

The amount he needs to pay = $ 650

Step-by-step explanation:

Area= h* (a+b/2)

    = 10 * (10+16/2)

    = 10 * (26/2)

    = 10 * 13 = 130 sq.feet

The amount he needs to pay = 130 * 5 = $ 650

Suppose that a company claims that its air fresheners last 23 days, on average. You take many large samples, and find, each time
Mice21 [21]
The answer is C 23. The problem says that "the mean number of days of the sample" is outside the confidence interval. The mean number of days of the sample is equal to 23. If 23 is outside the confidence interval, this is probably not the mean number of days that the company's air fresheners last.

Find the distance between each

between points (x1,y1) and (x2,y2)
D=\sqrt{(x2-x1)^2+(y2-y1)^2}



find and verify that
BC=CD=DE=EB

so
BC=\sqrt{(0-(-5))^2+(6-1)^2}=5√2
CD=\sqrt{(5-0)^2+(1-6)^2}=5√2
DE=\sqrt{(-4-1)^2+(0-5)^2}=5√2
EB=\sqrt{(-5-0)^2+(1-(-4))^2}=5√2
