What is the equation of the circle with center (-3,1) that passes through the point (-5, 3)?
A)
(x - 3)2 + (y + 1)2 = 8
B)
(x + 3)2 + (y – 1)2 = 8
0)
(x + 1)2 – (y - 3)2 = 8
D)
(x + 3)2 - () - 1)2 = 8

Answers

Answer 1

Answer:

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Step-by-step explanation:

The equation of a circle with center (h,k) and radius r is given by:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

Given

Center = (h,k) = (-3,1)

=> h = -3

=> k = 1

The distance between the center of circle and the point through which the circle passes will be the radius.

The distance formula is given by:

[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Given

[tex](x_1,y_1) = (-3,1)\\(x_2,y_2) = (-5,3)[/tex]

Putting the values in the formula

[tex]r = \sqrt{(-5+3)^2+(3-1)^2}\\r = \sqrt{(-2)^2+(2)^2}\\r = \sqrt{4+4}\\r = \sqrt{8}[/tex]

Putting the values of h,k and r in general form of equation

[tex]\{x-(-3)}^2\} +(y-1)^2 = (\sqrt{8})^2\\(x+3)^2+(y-1)^2 = 8[/tex]

Hence,

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Answers

So according to this equation
2x+5=-1
=>2x = -1-5(when 5 goes to the right side it sign changes)
=>2x = -6
=>x = -6/2 (when 2 goes to the right side it gets divided)
=> x = -3
Answer is the value of x is -3.

Ronnie made 5 pies for New Year's Day. Some of his family members are allergic to gluten, so he bought gluten-free flour for all of the pies. For each piecrust, he used 2 cups of flour. Health Mart sold bags with 4 cups of gluten-free flour for $12. How much did Ronnie spend on the gluten-free flour so that he had enough for the crusts?

Answers

Answer:

He spent $24 dollars

Step-by-step explanation:

Each of the piecrusts had 2 cup of flour he has 5 pies so all pies altogether equally 10 cups so he buys 2 bags for $24 dollars

Step-by-step explanation:

Number of gluten-free flour used for 5 pies= 2×5= 10 cups

cost of 4 cups of gluten-free flour = $12

cost of 1 cup = 12/4 = $3

Then,

cost of 10 cups of gluten-free flour = 3×10

= $30

Tyson got a $15 gift card to use on song and movie downloads to his tablet. Each movie, m, costs $5 and each song, s, costs $1. Tyson's mom said he must use fewer than 10 downloads and that his total cost could not exceed the $15 amount on the gift card. Which of the following graphs shows the solution set of the system of inequalities?​

Answers

Answer:

c

Step-by-step explanation:

bla bla bla

The solution to the inequality m + s = 10  and 5 m + 1s = 15 is shown in the graph attached below, and as it can be seen the coordinated of intersections are  (8.75, 1.25), so option C is correct.

What is inequality?

Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal

Given:

Total balance on card = $15,

The cost of each movie = $5,

The cost of each song = $1

The number of downloads  = 10,

Write the equation as shown below,

m + s = 10  and 5 m + 1s = 15

Here m is the number of movies and s is the number of songs,

Solve the equation by elimination method,

m = 5/4  = 1.25 and s = 35/4 = 8.75

As you can see, the value of the intersection of inequalities is (8.75, 1.25),

the graph is attached below.

Trisha’s parents bought a new house that has 2,255 square feet.
The price per square foot was $98. How much did they pay for the house? Enter your answer in the box.

Answers

Answer:$220,290

Step-by-step explanation:

2,255 multiplied by 98 is 220,290

The total cost of Trisha’s parents new house is $220990.

Given that, Trisha’s parents bought a new house that has 2,255 square feet.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The price per square foot was $98.

So, the total cost of house = Number of square feet × The price per square foot

= 2,255 × 98

= $220990

Therefore, the total cost of Trisha’s parents new house is $220990.
