Answer:
Step-by-step explanation:
-2x^2 + 4y
x = -2
y=3
just substitute into the equation
-2(4) + 4(4)
-8+16 = 8
Answer:
The value is: [tex]4[/tex]
Step-by-step explanation:
You have the following expression:
[tex]-2x^2+4y[/tex]
The exercise provides you these values of the variables "x" and "y":
[tex]x =-2\\y = 3[/tex]
Then, in order to find the value of [tex]-2x^2+4y[/tex], you need to substitute the given values of the variables into the expression.
Therefore, its value is:
[tex]-2x^2+4y=-2(-2)^2+4(3)=-2(4)+12=-8+12=4[/tex]
