You can get this by using the quadratic equation with a = 7, b = -1, c = -9
14 coins. 140/10 = 14 :) Hope this helped!
<span>The answer is:
T : (x, y) (x + 4, y + 3)
</span>T⁻¹<span>: (x, y) (x - 4, y - 3)
</span><span>The basic principle is to find the inverse function of F, such that T*</span>T⁻¹ = T⁻¹ * T = I.
Step-by-step explanation:
T1=a
T2=ar
r=T2÷T1
r=--18÷6
r=-3
T11=ar^10
T11=6×-3^10
T11=-354294
Answer:x=2, y=1, z=-1
Step-by-step explanation:
Given
2x+y+z=4----1
x-y+3z=-2----2
-x+y+z=-2----3
Add 2 & 3 we get
4z=-4
z=-1
Put value of z in 1 & 2
2x+y-1=4
2x+y=5----3
x-y+3(-1)=-2
x-y=1------4
add 3 & 4 we get
x=2
Put x & z in 1
y=1
