In the y=mx+b format or a linear equation, this would be y=15x+25
Suppose :
2^x = t ..**&**.. 3^y = u
_____________________________
t + u = 9 × 3 3t + 3u = 27
=====》
2t - 3u = 8 2t - 3u = 8
+ __________
5t = 35
5 × t = 5 × 7
t = 7
&
u = 2
________________________________
Thus :
2^x = 7 ===》 x = Log _ 2 { 7 }
3^y = 2 ===》 y = Log _ 3 { 2 }
Answer:
B
Step-by-step explanation:
b and a=40⁰ so if b+c is supplementary they equal 180⁰ together so 180-40= 150⁰
121 x 12 = 1452 so over 1500 is not a correct estimate. Less than 1500 is the right estimate
