Radius is the distance between the center and any point on the circle.
r=distance =√((x2-x1)² +(y2-y1)²) =√((5-(-3))²+(-7-(-1))²)=√(64+36)=√100 = 10
r=√100

Equation of the circle , where (h, k) coordinates of the center of the radius.
(h,k)=(5,-7)
(x-h)² +(y-k)² = r²
(x-5)² +(y+7)² = (√100)²
(x-5)² +(y+7)² = 100

Which of the expressions below can be factored using the difference of squares method? A. 25x2 - 64y2 B. 17x2 + 23y2 C. 17x2 - 2

denis-greek [22]

Difference of squares method is a method that is used to evaluate the difference between two perfect squares.

For example, given an algebraic expression in the form:
$x^2-y^2$
can be factored as follows:
$(x-y)(x+y)$

From the given expressions, the only expression containing two perfect squares with the minus sign in the middle is the expression in option A.
i.e. $25x^2-64y^2$
which can be factored as follows:
$(5x-8y)(5x+8y)$ .

Answer:

Step-by-step explanation:

2k+10 | Both terms share the common factor two, so you can take it out (divide both terms by 2)

2(k+5) | Now if you use the Distributive Property to double check, you get 2k+ 10 again

Answer:

7x-7=y

Step-by-step explanation:

5x+7y=10

5x-10=10-7y-10

5x-10=-7y

(1/7)5x-10=7y(1/7)

5x/35-10/70=y

7x-7=y

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?

Maksim231197 [3]

The answer is: [C]:
__________________________________________________________
Multiply each side by −8, subtract 35 from each side.
___________________________________________________________
Explanation:
___________________________
Given: You have (-1/8)*(x + 35) = -7
________________________________________
Note that all the answer choices given start with: "Multiply each side by....";
____________________
Given the choices, multiplying EACH SIDE of the equation by "(-8)" would make sense, since doing would cancel the "(-1/8)" on the "right-hand side" of the equation above to a "1" (i.e "cancel out" that ("-1/8") value); and would result in making the "right side" of the equation above ("-7") a positive integer number.
Then you would be left with: x + 35 = 56 ; so the next step would be to:
__________
Subtract: "(35)" from each side of the question [hence the answer choice] to isolate "x" on one side of the equation; and to solve for "x".
