Solve 3x+2y=16 and y=x+3 using substitution. find the ordered pair. show all the steps taken to find the answer.

(2,5)

or x=2, y=5

Step-by-step explanation:

3x+2y=16

substitute y =x+3 every place  you see a y

3x + 2(x+3) = 16

distribute

3x + 2x  +6 = 16

combine like terms

5x+6 = 16

subtract 6 from each side

5x+6 -6 =16-6

5x =10

divide by 5

5x/5 = 10/5

x = 2

now we need to find y

y = x+3

y = 2+3

y=5

(2,5)

or x=2, y=5

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
