Question

2•х²-0,5у+6. При х=-3 У=4 Срочно

Answer 1

=2*(-3)²-0,5*4+6=2*9-2+6=18-2+6=22

Answer 2

To find the value of the expression 2•х²-0,5у+6 when x = -3 and y = 4, follow these steps:

Step 1: Substitute the given values of x and y into the expression. Step 2: Perform the calculations.

Let's proceed:

Step 1: x = -3 y = 4

Step 2: 2•х² - 0.5у + 6 2•(-3)² - 0.5•4 + 6

Now, perform the calculations: 2•(-3)² = 2•9 = 18 0.5•4 = 2

Final result: 18 - 2 + 6 = 22

So, when x = -3 and y = 4, the value of the expression is 22.
