The answer is second one (-2)
Answer:
Is the question, "How long will it take the worm to leave the well?"
If so then the worm will leave the hole on the fifth day.
Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)
Answer:
Step-by-step explanation:
7y⁴ = 7y²(z - 3ax)
Divide both sides by 7y².
y² = z - 3ax
Add 3ax to both sides. Subtract y² from both sides.
3ax = z - y²
Divide both sides by 3a.
Step-by-step explanation:
If the zeros are 5 and 9, then the equation will have the form:
y = a (x–5) (x–9)
We know the point (0, 90) is on the curve, so we can use this to find the coefficient a:
90 = a (0–5) (0–9)
90 = 45a
a = 2
y = 2 (x – 5) (x – 9)
