Question

5+4y при y=3;-7;0,25;- 4/3; -1/42

Answer 1

Ответ:

Пошаговое объяснение:

у=3

5+4*3=5+12=17

у=-7

5+4*(-7)=5-28= -23

у=0

5+4*0=5

у=25

5+4*25=5+100=105

у= -4/3

5+4*(-4/3)= 5+4/1*(-4/3)=5/1+(-16/3)=15-16/3=-1/3

Answer 2

To evaluate the expression 5 + 4y for different values of y, simply substitute each value of y into the expression and perform the calculations:

1. When y = 3: 5 + 4(3) = 5 + 12 = 17

2. When y = -7: 5 + 4(-7) = 5 - 28 = -23

3. When y = 0.25: 5 + 4(0.25) = 5 + 1 = 6

4. When y = -4/3: 5 + 4(-4/3) = 5 - 16/3 = (15 - 16)/3 = -1/3

5. When y = -1/42: 5 + 4(-1/42) = 5 - 4/42 = (210 - 4)/42 = 206/42 = 103/21

So, the values of the expression 5 + 4y for the given values of y are as follows:

y = 3: 17 y = -7: -23 y = 0.25: 6 y = -4/3: -1/3 y = -1/42: 103/21
