Evaluate 8c+5d when c=−3 and d=4.
To evaluate the expression, substitute c = -3 and d = 4 into the expression 8c + 5d:
8c + 5d = 8(-3) + 5(4)
Simplifying further:
= -24 + 20
= -4
Therefore, 8c + 5d = -4 when c = -3 and d = 4.
8c + 5d = 8(-3) + 5(4)
Simplifying further:
= -24 + 20
= -4
Therefore, 8c + 5d = -4 when c = -3 and d = 4.
