Question

1. 3 Х если Х=-3.5 2. Х+3 если Х= -3 1 3 3. -5y если y = 0.3 4. y-5 если y= 3/5

Answer 1

Ответ: 1)3x=-3,5•3=-10,5

2)(x+3)=-3,1+3=-0,1

3)-5y= 3/5•(-5)=-3

4)(y-5)=3/5-5=-4 4/5

Answer 2

To evaluate the given expressions, simply substitute the value of the variable indicated and perform the calculations. Let's go through each expression:

1. 3 * X if X = -3.5 Replace X with -3.5: 3 * (-3.5) = -10.5

2. X + 3 if X = -3 1 3 It seems there might be a typo in the expression. Assuming it's X = -3 + 1/3, we can calculate it: X = -3 + 1/3 X = -9/3 + 1/3 X = -8/3

   Now, replace X with -8/3: -8/3 + 3 = -8/3 + 9/3 = 1/3

3. -5y if y = 0.3 Replace y with 0.3: -5 * 0.3 = -1.5

4. y - 5 if y = 3/5 Replace y with 3/5: 3/5 - 5 = 3/5 - 25/5 = -22/5
