7x -7/2 y = -49
7/2 y = 7x + 49
y = 2x + 14
y - intercept = 14
x - intercept : 2x + 14 = 0 so x = -7
answer is C.
x - intercept : -7
y - intercept : 14
Quadrant one
Hope this helped
18 tens= 180
20 ones= 20
180+20= 200

Answer:
Step-by-step explanation:
Let first group of people take x candies each
and second group of people take y candies each
5x + 7y will be total candies
5x +7y = 239 (needed to find positive solution of x,y)
now take x=38, y =7
or x=31, y= 12
hence lots of possibilities ,so we can not say exactly
Plugging in x=-2, you get:
2(-2)^2+5(-2)=2*4-10= -2
Therefore, f(-2)= -2
