Answer: (5,2)
Step-by-step explanation:
Given equations: 
Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get
Adding equation (3) and (4), we get
Substitute x=5 in equation (4), we get
Hence, the solution of the both equations is (5,2).
Answer:
y=-2x+2
Step-by-step explanation:
Just follow the slope-intercept form formula-
Formula: y= mx+b
Key:
y = y-coordinate
m = slope
x = x-coordinate
b = y-intercept

<span>15-h)*h=40
15h-h^2=40
h^2-15h+40=0
solve for h by quadratic formula:
a=1, b=-15, c=20
ans:
h=3.47 or 11.53 cm (height)
b=15-h=11.53 or 3.47 cm (base)</span>
Hence the number of packages of screws in each shipping box is: 469
Hence option (B) is correct.
