Slope intercept is y=mx+b
y=-1x-3
A)
y=2^x
4^x=2^(2x)=y²
solution:
y=2^x hence y²=4^x
chek:
x=5 ⇒ y=2⁵=32
4⁵=1024
y₂=32²=1024
b)
8(4^x)-9(2^x)+1=0
8(2^(2x)-9(2^x)+1=0
2^x=t
8t²-9t+1=0
We solve the quadratic.
t₁=1/8 ⇒2^x=1/8
2^x=1/2³
2^x=2⁻³
x=-3
t₂=1 ⇒ 2^x=1 ⇒x=0
Solutions:
x=-3
x=0
Sum of interior angles = 180(n - 2)
in this case n = 5 so 180(5-2) = 180(3) = 540
120 + 120 + x + x + x = 540
3x + 240 = 540
3x = 300
x = 100
answer
B) 100
