Answer:
Then the solution is (-1/4, 3)
Step-by-step explanation:
Start by eliminating the fractional coefficient 1/4: multiply all 3 terms in the second equation by 4. This results in equation (b), below:
4x - 3y = -10 (a)
4x = y -4 (b)
Substitute y - 4 for 4x in equation (a):
y - 4 - 3y = -10
Combining like terms, we get -2y = -10 + 4, or -2y = -6, or y = 3.
Since x = (1/4)y - 1, if y = 3, then x = (1/4)(3) - 1, or x = 3/4 - 1, or x = -1/4
Then the solution is (-1/4, 3)
Answer:
check question i have not understand
Answer:
a. The 0.3 means that the population is growing by 30% each decade. The 100,000 means that the population is 100,000 in 1970.
b. The equation for the population y years after 1970 is
p(y) = 100,000 (1 + 0.3)^1/12
c. The equation for the population e centuries after 1970 is
p(e) = 100,000 (1 + 0.3)^10
P.S. Probably right, an exercise to you, to check.
