solve this answer by using substitution. set the first equation to x=-y+4 then substitute -y+4 for x in the second equation.
2(-y+4) + 3y=0
-2y+8 + 3y=0
y+8=0
y=-8
now use -8 and solve for x
x+(-8)=4
x=12
Answer:
Step-by-step explanation:

A root of a polynomial doesn't mean it is a square root of!!!!!!
P(x)=3(x-5)(x-2)=3x²-21x+30
f (x)= 3 x power point 2 - 21 x + 30
Answer:
Step-by-step explanation:
the displacement of the particle is given by

The rate of change of position gives the value of velocity.
So, v = ds/dt
Differentiate the position function with respect to time.

Now, at t = a
v = -18/a³ m/s
At t = 1
v = - 18 m/s
At t = 2
v = - 18 / 8 = - 2.25 m/s
At t = 3
v = - 18 / 27 = 0.67 m/s
Assuming that means 1.10^t:
0.10 is for years. To get months divide by 12.
0.10/12 = 0.0083333...
And (1+0.083333...) = 1.0833333. (You will have to multiply t by 12 also to get it in terms of months)
(1.0833333)^12t
