se the number line to answer the question. A number line going from negative 5 to positive 5. Point A is negative 1, point B is 0, point C is 1, and point D is 4.5. Which statement about graphing rational numbers is true? The graphs of all rational numbers will be to the right of point B. The graphs of all rational numbers will be to the left of point B. Point D does not represent a rational number. All of the points on the graph could represent rational numbers.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

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.
