Answer:
The solution to the system of equations is x=3 y= 23
Step-by-step explanation:
solving this system of equation using substitution method
-3x-y=14 ….. equation (1)
-9x =-27 ….. equation (2)
Solving for value of x from equation 2
-9x =-27
so x= -27/-9 = 3
so x = 3
The second equation is solved for x, so we can substitute the expression 3 in for x in the first equation (1)
-3x-y=14
-3 (3) - y =14
-9-y= 14
-9=14+y
y=-23
The solution to the system of equations is x=3 y= -23
We can check our work by plugging these numbers back into the original equations. Let's try -3x-y=14
-3x-y=14
-3(3) -(-23)= 14
-9+23 = 14
14= 14
Yes, our solution checks out.
The correct answer is the commutative property of multiplication. This states that 2 or more numbers can be multiplied in either order.
Answer: 14 Pizzas
2 pizzas means each kid gets one
so 7 times 2 is 14 so I beleive the answer is 14
Answer:
y=-½x+1
Step-by-step explanation:
The slope is negative because it goes down from left to right
The y-intercept is ½ because the point where the line meets the y-axis is ½
