Question

вычислите значение у при следующих значениях переменной
х=-2 х=-2 х=0 х=1х=2
у=8х
у=-2х
у=3х
у=-х-3
у=10х+8

Answer 1

1) y = 8 * (-2) = -16

y = 8 * 0 = 0

y = 8 *1 = 8

y = 8 * 2 = 16

2) y = -2 * (-2)= 4

y = -2 * 0 = 0

y = -2 * 1 = -2

y = -2 * 2 = -4

3) y = 3 * (-2) = -6

y = 3 * 0 = 0

y = 3 * 1 = 3

y = 3 * 2 = 6

4) y = - (-2) - 3 = -1

y = 0 - 3 = -3

y = -1 - 3 = -4

y = -2 - 3 = -5

5) y = 10 * (-2) + 8 = -12

y = 10 * 0 + 8 = 8

y = 10 * 1 + 8 = 18

y = 10 * 2 + 8 = 28
