Answer:
They bought 5
Step-by-step explanation:
65x+40y=765
65(5)+40(11)=765
x + 7 = 2(3x - 4) Remove the brackets
x + 7 = 2*3x - 4*2
x + 7 = 6x - 8 Subtract 7 from both sides.
x + 7 - 7 = 6x - 8 - 7
x = 6x - 15 Subtract 6x from both sides
x - 6x = - 15
-5x = - 15 Divide by -5
-5x/-5 = -15/-5
x = 3
The slope is 1/6 and the y intercept is 7

Answer:
Step-by-step explanation:
take two points on the line ,i take (-4,0) and (0,-2)
slope=(y2-y1)/(x2-x1)=(-2-0)/(0+4)=-2/4=-1/2
