Answer:

y = 3( $0.5^{x}$ )

Step-by-step explanation:

Exponential function has the form f(x) = k $b^{x}$ where b > 0 and b ≠ 1

~~~~~~

3 = k × $b^{0}$ ⇒ k = 3

1.5 = 3( $b^{1}$ ) ⇒ b = 0.5

Thus, y = 3(  $0.5^{x}$  )

Answer: $x=7, \ y=-2$

Step-by-step explanation:

Given

Equations are $3x-y=23$ and $2x+3y=8$

take $3x-y=23$

$y=3x-23$

Put the value of y in another equation

$\Rightarrow 2x+3(3x-23)=8\\\Rightarrow 2x+9x-69=8\\\Rightarrow 11x=77\\\Rightarrow x=7$

Put the value of x in y

$y=3(7)-23=21-23=-2$

Hence, $x=7, \ y=-2$
