Answers

Answer: (x - 2)^2 + (y + 3)^2 = 18 3(2^(1/2)) (2,-3)

Step-by-step explanation:

7x^2 - 28x + 7y^2 + 42y - 35 = 0

divide 7 out

x^2 - 4x + y^2 + 6y - 5 = 0

add 5 to other side

x^2 - 4x + y^2 + 6y = 5

solve by completing the square

take b values divide them by 2 square and add to both sides

-4/2 = -2

-2^2 = 4

6/2 = 3

3^2 = 9

X^2 - 4x + 4 + y^2 + 6y +9 = 4 + 9 +5

(x - 2)^2 + (y + 3)^2 = 18

(x - k)^2 + (y - h)^2 = r^2

r^2 = 18

r = [tex]\sqrt{18}[/tex] = 3[tex]\sqrt{2}[/tex] = 3(2^(1/2))

What is the recursive rule?

Question 2 options:

an = an+1 + 500; a1 = 30,000

an = an−1 + 30,000; a1 = 500

an = an−1 + 500; a1 = 29,500

an = an−1 + 500; a1 = 30,000

Answers

Mr. Red's salary is an illustration of an arithmetic sequence

The recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000

How to determine the recursive formula?

From the complete question, we have the explicit rule of Mr. Red's salary to be

an = 500n + 29500

Where:

First term, a1 = 30000Common difference, d = 500

The above means that:

The difference between a term and the next term is 500.

So, the recursive rule is:

an = an−1 + 500

Recall that:

a1 = 30000

Hence, the recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000

Answers

Answer:

a. y = 10

b. x = 5 - (5y/2)

c. y = 6x - 11

Step-by-step explanation:

2(y - 3) = 4

2y - 6 = 4

2y = 10

y = 5

2x + 5y = 10

2x = 10 - 5y

x = 5 - (5y/2)

6x + 3y = 4y + 11

6x = y + 11

y = 6x - 11

a rectangle has an area of 54 square inches the width of the rectangle is 9 inches what is the langth

Answers

Answer:

Area of rectangle is 54 square inchesWidth of the rectangle is 9 inches.

We have to calculate the length of rectangle .

As we know the formula to find the Area of rectangle .

[tex] \boxed{\bf \: Area_{(Rectangle)} = length \: \times width}[/tex]

On substituting the value we obtain

[tex] \sf \qquad \: \longrightarrow 54 = length \times 9 \\ \\ \\ \sf \qquad \: \longrightarrow \cfrac{54}{9} = length \\ \\ \\ \sf \qquad \: \longrightarrow \: length \: = \cfrac{54}{9} \\ \\ \\ \sf \qquad \: \longrightarrow \: length \: = \cancel \cfrac{54}{9} \\ \\ \\ \sf \qquad \: \longrightarrow \: length \: = 6 \: inches[/tex]

Therefore,

Length of the rectangle is 6 inches .

A brand new vehicle costs $25,399. It decreases in value by 8.5% each year after its purchase.

Which function models the value of the vehicle in dollars x years after its purchase?

f(x)=1.085(25,399)x

f(x)=0.915(25,399)x

f(x)=25,399(0.915)x

f(x)=25,399(1.085)x

Answers

The cost after x years is the initial cost minus the amount of decrease after the duration of x years

Percentage Decrease

Given Data

Initial Cost of vehicle = $25,399Rate of decrease = 8.5%Duration = yearly

Let us find 8.5% of $25,399

= 8.5/100*$25,399

= 0.085*25399

= 2158.915

Cost after x years will be

Final cost = 25,399 - 2158.915*x

Under a dilation, are the pre-image and the image always,

Answers

Answer:

Never congruent

Step-by-step explanation:

A dilation is a transformation that makes an image that is thr same shape as the original, but a DIFFERENT SIZE.

Congruent shapes means they both have the same shape AND size.

Answer(s):Range: 7Mode: 2Step-by step explanation:

Given data:

1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 8

1. Determining the range of the line plot:

To determine the range of the data, we need to subtract the biggest value of the data (8) from the smallest value of the data (1).

⇒ Range of a data: Biggest number - Smallest number⇒ Range of a data: 8 - 1⇒ Range of a data: 7

Thus, 7 is the range.

2. Determining the mode of the line plot:

The mode of the data is the digit that has repeated the most. In this case, the digit "2" has repeated five times and has repeated the most.

Henceforth, "2" is the mode.

There is a bag filled with 4 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?

Answers

Answer:

16/81

Step-by-step explanation:

Given

In the bag, there are : 4 blue and 5 red marbles

Probability of blue (1st time)

P(1) = Total blue / Total marblesP(1) = 4 / (4 + 5)P(1) = 4/9

Probability of blue (2nd time)

P(2) = Total blue / Total MarblesIt states it is replaced hence it is of the same constitution as the beginningP(2) = 4/9

Probability of blue (both times)

P = P(1) x P(2)P = 4/9 x 4/9P = 16/81

Solution:

Let's solve the given problem step by step :

[tex]:\implies \quad \sf - 3(x + 5) = - 9[/tex]

First, distribute the given problem :

[tex]:\implies \quad \sf - 3(x + 5) = - 9[/tex]

[tex] \sf:\implies \quad - (3 \times x) - (3 \times 5) = - 9[/tex]

Add 15 to both sides :

[tex] \sf:\implies \quad - 3x - 15 = - 9[/tex]

[tex] \sf:\implies \quad - 3x - 15 + 15 = - 9 + 15[/tex]

On simplifying :

[tex] \sf:\implies \quad -3x-15+15 = -9+15[/tex]

[tex] \sf:\implies \quad - 3x = 6[/tex]

Dividing both sides with same factor :

[tex] \sf:\implies \quad - 3x = 6[/tex]

Answers

The formula that describes the width of the rectangle as a function of length is w = 55 / m.

How to find area of a rectangle?

area of a rectangle = lw

where

l = lengthw = width

Therefore,

area = 55 inches²

length = m

width = w

Hence,

area = mw

55 = mw

divide both sides by m

55 / m = wm / m

w = 55 / m
