Answer:
-4
Step-by-step explanation:
Answer: Combine like terms!
Step-by-step explanation:
-4x + 3x = 2
-1x = 2
-1x/-1 = 2/-1
x = -2
A)4^(n+3)=8^14
2^(2×(n+3))=2^(3×14)
2^(2n+6)=2^42
2^2n=2^36
n=18
b) (assuming a : is divide)
3^(2n+1)=9^17/3^3
3^(2n+1)=3^(2×16)/3^3
3^(2n+1)=3^29
3^2n=3^28
2n=28
n=14
d) (6^n)^4×36=216^10
6^4n×6^2=6^(3×10)
6^(4n+2)=6^30
6^4n=6^28
4n=28
n=7
e)7^(n^2)÷7=49^24
7^(n^2-1)=7^(2×24)
7^(n^2)=7^49
n^2=49
n=7
g)15^(n+4)÷5^(n+4)=81^6
3^(n+4)×5^(n+4)÷5^(n+4)=3^(4×6)
3^(n+4)=3^24
n=20
h)81^n÷9^n+9^(n+2)÷9=90÷9^6
9^2n÷9^n+9^(n+2)÷9=9*10/9^6
9^n+9^(n+1)=10/9^5
I don't know where to go from here
I)what?
Answer:
y = 17*(3)ˣ
Step-by-step explanation:
y=abˣ
(0,17) : 17 = a*b⁰ = a
(2,153) : 153 = a*b² = 17*b²
b² = 153/17 = 9
b = ± 3 ... (0,17) and (2,153) in first quadrant b = 3
function: y = 17*(3)ˣ
93 is not a multiple of 9. Multiple of 9 would be 90 or 99. These are multiples of 9 in a range from 0 up to 100:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99
