3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
= 17-y-1-x
= 16-x-y
by starting from the number on the z axis and going up from the y axis
Answer:
The slope is -3/4
Step-by-step explanation:
The formula to calculate slope is m = (y2 -- y1) / (x2 -- x1), where m is the slope. When we substitute the values, we get 0-3 over -2-2. When we solve this, 0-3 is -3 and -2-2 is -4, so the slope is -3/4.
f(x) = 3x + 5/x
f(a + 2) = 3.(a + 2) + 5/(a + 2)
