Can someone put this equation in standard form for me? y-3=1/5(x-3)

Standard form : Ax+By=C

Answers

Answer:

-x + 5y = 12

Step-by-step explanation:

Eliminate the fractional coefficient by multiplying both sides by 5:

5y - 15 = x - 3

Combine the constants: 5y = x + 12

Subtract x from both sides: -x + 5y = 12 This is in standard form

X + 1.5x - 0.75 = 73

what is the value of x?

Answers

x + 1.5x - 0.75 = 73
2.5x - 0.75 = 73
2.5x = 73 + 0.75
2.5x = 73.75
x = 29.5

The answer is: x = 29.5.

A circle is defined by the equation x2 + y2 + 8x + 22y + 37 = 0. What are the coordinates for the center of the circle and the length of the radius?

Answers

The center of the circle is: (-4 ; -11) and the radius of the circle is r = 10

What is equation of circle?

The general equation for a circle is (x-a)² + (y-b)² = r², where ( a, b ) is the center and r is the radius.

Given:

x² + y² + 8x + 22y + 37 = 0.

Now, to find both coordinates and radius write the given equation in standard form:

(x-a)² + (y-b)² = r²

x² + 8x + y²+ 22y= -37

( x² + 2* x*4 + 4²)+( y² + 2*y* 11 + 11²) = -37 + 16 + 121

(x + 4)² + ( y+ 11)² = 100

(x + 4)² + ( y+ 11)² = 10²

So, center of the circle is: (-4 ; -11)

and the radius of the circle is r = 10

We can say that:
8x = -2ax
8 = -2a
a = -4

22y = - 2by
22 = -2b
b = -11

37 = a² + b² - r²
37 = (-4)² + (-11)² - r²
r² = 16 + 121 - 37
r² = 100
r = 10

With all this information, we can say that:
The center of the circle is: (-4 ; -11)
and the radius of the circle is r = 10

P.S:
(a - x)² + (b-y)² = r²
a² - 2ax + x² + b² -2by + y² - r² = 0
x² + y² -2ax - 2by + a² + b² - r² = 0

If 2x2+13x-7=0 then x could be equal to which of the following

Answers

Answer:

x = - 7, x = $(1)/(2)$

Step-by-step explanation:

Given

2x² + 13x - 7 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 7 = - 14 and sum = + 13

The factors are + 14 and - 1

Use these factors to split the x- term

2x² + 14x - x - 7 = 0 ( factor the first/second and third/fourth terms )

2x(x + 7) - 1(x + 7) = 0 ← factor out (x + 7) from each term

(x + 7)(2x - 1) = 0

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = $(1)/(2)$
