7x + -10 = 25
in steps

X=5

Step-by-step explanation:

you need to rearrange the equation

meaning move the negative 10 to the other side

when you move the 10 to the other side make sure to change its symbol.

7x-10=25

7x=25+10

now solve using order of operations

7x-10=25

7x=35

last divide by 7

x=35/7

x=5

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
