Question

Evaluate please
2x+(−6)∙(y+1) for x=−1.5 and y=−3

Answer 1

First, you plug your given values in. Since x is 1.5, it will be multiples by 2x to get 3.2. Since y is -3, it will be added to 1 to get -2. Finally, the two are multiplied together to get -6.4 if I am correct. 

Answer 2

9

Explanation:

2 multiplied by -1.5 = -3.0

y + 1 = -2

So, the equation would be:

-3 - 6 multiplied by -2

Using the rule of PEMDAS, you would multiply -6 and -2 first, making the new equation now:

-3 + 12

12 - 3 = 9, resulting in the answer.
