Answer:
"If Kendrick is excited, then music class is next."
Step-by-step explanation:
The conditional would be "not." If it is not, he is not. "If music class is next, then Kendrick is exited" could be correct if the grammar was too. You do not know if music class is next so they couldn't be excited. However, if he is excited, then music class has to be next.
Answer:
( -4, -3 )
Step-by-step explanation:
Let's solve by elimination. Reason being there are no variables without coefficients.
−5y+3x=3 Multiply equation by 3. Each term.
−8y+9x=−12
-15y + 9x = 9 Subtract the to equations
-8y + 9x = -12
___________
-7y = 21
y = -3
Substitute y into original equation
-5(-3) + 3x = 3
15 + 3x = 3 Subtract 15 both sides
3x = -12 Divide by 3, both sides
x = -4
