Answer:

centre = (- 1, - 3 ) , radius = 6

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

given

x² + y² + 2x + 6y = 26 ( collect x and y terms )

x² + 2x + y² + 6y = 26

using the method of completing the square

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(1)x + 1 + y² + 2(3)y + 9 = 26 + 1 + 9

(x + 1)² + (y + 3)² = 36 ← in standard form

with centre = (- 1, - 3 ) and r = [tex]\sqrt{36}[/tex] = 6

[tex](x {}^{2} + 2x + 1) - 1 = (x + 1) {}^{2} - 1[/tex]

[tex](y {}^{2} + 6y + 9) - 9 = (y + 3) {}^{2} - 9[/tex]

[tex](x + 1) {}^{2} - 1 + (y + 3) {}^{2} - 9 = 26[/tex]

[tex](x + 1) {}^{2} + (y + 3) {}^{2} = 26 + 10[/tex]

[tex](x + 1) {}^{2} + (y + 3) {}^{2} = 36[/tex]

[tex](x - a) {}^{2} + (y - b) {}^{2} = r {}^{2} [/tex]

[tex]r {}^{2} = 36[/tex]

[tex]r = \sqrt{36} = 6[/tex]

Answer:

=> -4

Step-by-step explanation:

7 + x = 5

=> x = 5 - 7

=> x = -2

Putting the value of x = -2 in equation 3x + 2

=> 3(-2) + 2

=> -6 + 2

=> -4

Answer:

-4

when 7 +x =5   solve for x by subtracting 7

x=5-7 =-2

3x+2 =               substitute (-2) for x

3(   )+2

Answer:

42 sq. cm

Step-by-step explanation:

Answer: 42 sq. cm

Length of Big Rectangle: 7

Width of Big Rectangle 7+0.5+0.5 = 8

Area of Big Rectangle: 56

Area of Small Rectangle = 0.5*7 = 3.5

Area of 4 Small Rectangles = 3.5 *4 = 14

Shaded Area = Big Rectangle - 4 Small Rectangles = 56 - 14 = 42 sq. cm

Answer:

After 16 days:  17.6 pounds

After 6 weeks: 46.2

Step-by-step explanation:

1.1 x 16 = 17.60

42 x 1.1 = 46.2  (6 weeks x 7 days a week = 42)

The weight loss after 16 days will be 17.6 pounds and after 6 weeks will be  46.2.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that during a​ 6-week weight-loss​ regimen, Tony lost weight at a rate of 1.1 pounds per day.

The weight loss after 16 days will be calculated as,

1.1 x 16 = 17.60 pounds

The weight loss after 6 weeks will be calculated as,

42 x 1.1 = 46.2  (6 weeks x 7 days a week = 42)

Therefore, the weight loss after 16 days will be 17.6 pounds and after 6 weeks will be  46.2.

C: The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.

When we talk about the concept of translation in transformations, it means that the side lengths remain the same. This means the object is just moved from one place to another and the lengths are preserved.

However, when we stretch the polygon, it means we are increasing or decreasing at least one side length.

Thus, we can conclude that The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.

Answer:

∠ c = 29°

Step-by-step explanation:

∠ b and 97° are vertically opposite angles and are congruent , so

∠ b = 97°

the 3 angles in the triangle sum to 180° , that is

54° + b + c = 180°

54° + 97° + c = 180°

151° + c = 180° ( subtract 151° from both sides )

c = 29°

Answer:

Your age(a) is 15 in this case.

If your brother is 1/3 of your age, that means multiply your brother's age by 3

Your sister is 9, and is 4 years older than your brother. In that case, we now know that your brother is 5

With that information, we can put this into a valid equation.

------------------------------------------------------------------------------------------------------------

turn 1/3 into a flipped fraction, 3/1 which is equal to 3

your brother's age is 5, so the first value would be 5

5 times 3 is 15, so that means a is 15

[tex]5 * 3/1 = 15[/tex]

To solve ✅

We know that...

[tex]5\frac{1}{6} = 5 + \frac{1}{6}[/tex]

So that means

[tex]\frac{1}{6}[/tex] = 1 ÷ 6

And with that info, 5 1/6 becomes

[tex]5 + (\frac{1}{6})[/tex]

_______________________________________________________

Solve by improper fractions ➗

We know from the last problem that...

[tex]5\frac{1}{6} = 5 + \frac{1}{6}[/tex]

Converting 5 as a whole number to a fraction, it becomes

[tex]5 = \frac{5}{1}[/tex]

Now it becomes...

[tex]\frac{5}{1} + \frac{1}{6}[/tex]

Since the fractions will not change, first find the whole, then multiply your improper fraction by the whole, and add the part

[tex]\frac{6}{6}\\\\ = (\frac{5}{1} * \frac{6}{6} ) + \frac{1}{6}[/tex]

Converting to improper fraction

[tex]\frac{30}{6}\\\\= \frac{30}{6} + \frac{1}{6}(part) = \frac{31}{6}[/tex] never add the denominators when they are equal.

We know that...

[tex]\frac{31}{6}[/tex] = 31 ÷ 6

Whose quotient is equal to

Answer:

circumference of a circle formula is C=2*pi*r

Step-by-step explanation:

then  

141.3 = 2*pi * r

solve for r

141.3/ (2*pi) = r

22.48859 feet

diameter is  2*r

2*22.48859= 44.9771 feet

divide by 3 because there are 3 feet in one yard

44.9771/3= 14.99239 yds.  

it doesn't say to round off, but I would call this 15 yds.

Diameter is 15 yards   ± .008 yds  That's just about 1/4 of an inch

The paint in the pot is an illustration of a linear equation and the weight of the full pot is 11.2 kg

The given parameters can be represented using the following ordered pairs:

(x,y) = {(0.5, 5.8) and (0.25, 3.1)}

The slope of the equation is calculated using:

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

This gives

m = (3.1 - 5.8)/(0.25 - 0.5)

Evaluate

m = 10.8

The equation is then calculated using:

y = m(x - x1) + y1

This gives

y =  10.8(x - 0.5) + 5.8

Expand

y =  10.8x + 0.4

When the pot is full, we have x = 1

So, the equation becomes:

y =  10.8 * 1 + 0.4

Evaluate

y =  11.2

Hence, the weight of the full pot is 11.2 kg
