The equation would be 35.75x+6y=190
Answer:
r(t) = 75 kg - (4.5 kg/wk)w
Step-by-step explanation:
Let r(t) represent the amount of rice remaining after w weeks.
Then:
r(t) = 75 kg - (4.5 kg/wk)w
Options :
4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
Answer:
-8 + - 8 + - 8 + - 8
Step-by-step explanation:
Given that:
Rungs of ladder moved per stop = 4
Number of stops made = 8
Number of ladder rungs :
Ladder rungs per stop * number of stops
- 4(descent) * 8= - 32 ladder rungs
Alternative way :
-8 in 4 places
-8 + - 8 + - 8 + - 8 = - 32
y = mx + b
m = -3/4
y = (-3/4)x + b
Use the given point (4,-6) to find b:
-6 = (-3/4)(4) + b
-6 = -3 + b
b = -3
Final equation:
y = (-3/4)x - 3
(403 + 301 + 402 + 503 + 601) / 5 = 2210/5 = 442 <== ur answer
