2x – Зу = -1<br> + 3x+3y= 26<br> ОА. бу = 25<br> ОВ. 5х = 27<br> Ос. 5х = 25<br> OD. 5x - бу = -27
Brilliant_brown [7]

Answer:

C. 5x=25

Step-by-step explanation:

Given:

2x-3y=-1\\3x-3y=26

Add the two equations, we get

2x-3y+3x+3y=-1+26\\(2x+3x)+(-3y+3y)=25\\5x+0=25\\5x=25

Therefore, the correct option is option C.

Let x and y be two positive numbers whose sum is 175 and (x+3)(y+4) is a maximum
Vaselesa [24]

Answer:

Step-by-step explanation:

x+y = 175

y = 175 - x

f(x) = (x+3)(y+4)

= x(175-x) + 3(175-x) + 4x + 12

= 175x - x² + 525 - 3x + 4x + 12

= -x² +176x + 537

f'(x) = -2x + 176

maximum when x = 88

y = 175-x = 87
