Question

Вычислите значение y по формуле a=86 - 5b, если: 1) b=17; 2) b=9.

Answer 1

а = 86 - 5в,

1)

при в = 17:

а = 86 - 5 * 17 = 86 - 85 = 1,

2)

при в = 9:

а = 86 - 5 * 9 = 86 - 45 = 41

Answer 2

To calculate the value of y using the formula a = 86 - 5b, we substitute the given values of b into the formula and then solve for a.

1. When b = 17: a = 86 - 5 * 17 a = 86 - 85 a = 1

So, when b = 17, y (or a) is equal to 1.

2. When b = 9: a = 86 - 5 * 9 a = 86 - 45 a = 41

So, when b = 9, y (or a) is equal to 41.
