<em>Answer,</em>
<em>21 * 50 = </em><em>1,050</em>

19,5/100=0,195................
(27⁽⁻ˣ⁺³⁾) (9⁽ˣ⁺¹⁾) = 81
Instead of using logarithmic to find x, Notice that 27, 9 and 81 are the perfect powers of 3. Since 27 = 3³, 9 = 3², and 81 = 3⁴, so
(3³⁽⁻ˣ⁺³⁾) (3²⁽ˣ⁺¹⁾) = 3⁴
3³⁽⁻ˣ⁺³⁾⁺²⁽ˣ⁺¹⁾ = 3⁴
If the bases are the same, then cancel it and bring the power as a new base.
3(-x+3) + 2(x+1) = 4
-3x + 9 + 2x + 2 = 4
-x + 11 = 4
-x = 4 - 11
-x = -7
x = 7
Answer:
f(-2) = 20
Step-by-step explanation:
f(x) = 2x² - 3x + 6
f(-2) = 2(-2)² - 3(-2) + 6
= 2(4) + 6 + 6
= 8 + 12
= 20
