Answer:
y = -1/4x -2
Step-by-step explanation:
the perpendicular slope would be -1/4
2 = -1/4 (-16) + b
b = -2
the equation should be y = -1/4x -2

Answer is lots of god Which equation is the inverse of <em>y </em>= 100 – <em>x</em>2?




Answer: 9 rolls of cloth A and 44 roles of cloth B
Step-by-step explanation:
Let x represent the number of rolls of cloth A that can be dyed and dried.
Let y represent the number of rolls of cloth B that can be dyed and dried.
A roll of Cloth A requires 50 minutes of dyeing time. A roll of Cloth B requires 55 minutes of dyeing time. The production division allocates 2280 minutes of dyeing time. This means that
50x + 55y = 2880- - - - - - - -1
A roll of Cloth A requires 45 minutes of drying time. A roll of Cloth B requires 30 minutes of drying time. The production division allocates 1740 minutes of drying time. This means that
45x + 30y = 1740- - - - - - - -2
Multiplying equation 1 by 45 and equation 2 by 50, it becomes
2250x + 2475y = 129600
2250x + 1500y = 87000
Subtracting, it becomes
975y = 42600
y = 42600/975
y = 44
Substituting y = 44 into equation 1, it becomes
50x + 55 × 44 = 2880
50x + 2420 = 2880
50x = 2880 - 2420
50x = 460
x = 460/50
x = 9
Step-by-step answer:
If one is constrained to move to the right, or up, or diagonally upwards (i.e. remain in the first quadrant), then
there are three choices at A.
At the next position, whichever path one has taken, there are also three choices.
At the following position, there are no more choices.
Therefore, there are 3*3 = 9 different paths.
