Answer:
y = 2x + 13
y = –x – 2
Step-by-step explanation:
The options are:
y = 2x + 13
y = -x - 2
y = 3x - 5
y= -(1/2)x + 6
y = -2x - 2
The graph is shown in the figure attached. There, point (-5, 3) is shown. Replacing it into the equations we get:
y = 2(-5) + 13 = 3 (so, it is a solution)
y = -(-5) - 2 = 3 (so, it is a solution)
y = 3(-5) - 5 = -20 ≠ 3 (so, it isn't a solution)
y= -(1/2)(-5) + 6 = 8.5 ≠ 3 (so, it isn't a solution)
y = -2(-5) - 2 = 8 ≠ 3 (so, it isn't a solution)
Answer:
The money he can save by buying them at Big 5 is $76.80.
Step-by-step explanation:
Given:
Footballs sell for $27.99 each at Sporting Goods.
Footballs sell for $21.59 each at Big 5.
The coach buys a dozen footballs.
Now, to find the amount he save by buying them at Big 5.
So, first we find the cost of footballs at Sporting Goods and at Big 5.
1 Dozen = 12 pieces.
Thus, the cost of footballs at Sporting Goods =
And, the cost of footballs at Big 5 =
Now, to get the amount coach can save by buying them at Big 5, we subtract both the cost as the cost of Sporting Goods is more than the Cost of Big 5:
The amount coach can save by buying them at Big 5 =
Therefore, the amount he can save by buying them at Big 5 is $76.80.
