Final answer:
To evaluate the expression for y = -1 and z = -2.9, substitute these values into the expression -6y - 0.5z + 2.7. The value of the expression is 10.15.
Step-by-step explanation:
To evaluate the expression for y = -1 and z = -2.9, substitute these values into the expression.
The given expression is -6y - 0.5z + 2.7.
Substituting y = -1 and z = -2.9 into the expression, we get -6(-1) - 0.5(-2.9) + 2.7 = 6 + 1.45 + 2.7 = 10.15.
Therefore, the value of the expression is 10.15.
