Y= 3/4x
5/2x + 2y = 5

x = 5/4

y = 15/16

Step-by-step explanation:

substitute 3/4x for 'y' in the 2nd equation

5/2x + 2(3/4x) = 5

multiply each side by 4 to eliminate fractions:

10x + 6x = 20

16x = 20

x = 20/16 or 5/4

y = 3/4 · 5/4

y = 15/16

step-by-step explanation:

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)
