A big box retailer has one order for 9 plants and 6 bushes with a cost of $390. There is a second order for 7 plants and 8 bushes with a cost of $400.
Which system of equations can be used to determine the price of a plant, p, and the price of a bush, b?

9p +6b = 390
7p + 8b = 400

9p + 8b = 390
7p + 6b = 400

7p + 8b = 390
9p + 6b = 400

7p +95 = 390
6p+8b = 400

Here you go( I dont feel like taking a screen shot- sorry)

Step-by-step explanation:

Very helpful for k12 students, and hope this helps! sorry I am late.

9p+6b=390

7p+8b=400

(I took the test on this and got it right!)

step-by-step explanation:

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.
