Since we must save 50 meals for volunteers, the real amount we are giving away is 700 meals in 12 hours.
700/12 = 58.3333...
10*58.333.. = 583.333....
Since we can't serve 1/3 of a person, we take 583. Hope this helps!
Answer: -2/7
|3x - 2| - 4x = 4
1) (3х - 2) - 4х = 4, if 3x - 2 >= 0
2) -(3x - 2) - 4x = 4, if 3x - 2 < 0
1)
3х - 4х = 4 + 2
-x = 6
x = -6
3х - 2 >= 0
3х >= 2
x >= 2/3 - wrong
2)
-3х + 2 - 4х = 4
-7х = 2
x = -2/7
3x-2<0
3x<2
3(-2/7)<2-right
y=x^2-2x-15 (1) y=8x-40 (2)
8x-40=x^2-2x-15
X^2+10x-25=0
(x-5)^2
×=5 y=0
It is no solution, bc the answer is (0,0)
The midpoint of (x1,y1) and (x2,y2) is
just average them
(4,1) and (-2,4)
the midpoint is
(1,-1.5)
