y=-0.02(15)^2+15+2.6

Lösung

y = - 0.02 (15)^{2} + 15 + 2.6

y = 13.1

Schritte zur Lösung

y = - 0.02 (15)^{2} + 15 + 2.6

Vereinfache

- 0.02 \cdot 1 5^{2} + 15 + 2.6 : 13.1

y = 13.1

14 (2 x + 1) - 4 (3 x + 1) = - 6

4.1 - (3 x - 0.4) = 2 (x - 4) - 2

7 = \frac{x}{5} + 1

f = 3 (2) - 2

5 (2 x - 2) = 4 - 2 x
