James determined that these two expressions were equivalent expressions using the values of x - 4 and x-6. which
statements are true? check all that apply.
7x+4 and 3x+5+4x-1
when x-2both expressions have a value of 18.
the expressions are only equivalent for x = 4 and x = 6.
the expressions are only equivalent when evaluated with even values.
the expressions have equivalent values for any value of x.
the expressions should have been evaluated with one odd value and one even value.
1
when x = 0, the first expression has a value of 4 and the second expression has a value of 5.
the expressions have equivalent values if x = 8

step-by-step explanation:

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

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.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
