X will equal 0 and y will equal -3
Answer:
5/8
Step-by-step explanation:
How much pizza is left between Mary and Hector combined?
Since both had a medium pizza, we'll say the pizzas were the same size.
So, we just have to make the sum:
The addition is easy since both members of the addition have the same denominator (8). So, we just have to add up the numerators.
Since 5/8 is already expressed to its most simple expression, that's the answer.
Answer:
-8
Step-by-step explanation:
For a system to have infinitely many solutions the two equations must be the same line. We can simplify the first and second equations by dividing them by 3 and 2 respectively to get:
y + 4 = 2x
y = 2x + b/2 → y -b/2 = 2x
Since the constants must be equal, 4 = -b/2 which means b = -8.
Answer:
9x + 4y < 110
Step-by-step explanation:
This inequality works because its the cost of hammers ($9) multiplied by how many hammers are bought (x) plus the cost of wrenches ($4) multiplied by how many wrenches are bought (y). The total cost has to be less than 110.
