Answer:
Sofias solution is correct.
Step-by-step explanation:
First of all you do not need two sets of the same equation.
y=-1.5x + 5.7
y = 0.5x + 0.3
If you graph the y-intercepts first then graph the slope for the equation then you will get the right answer.
1) Graph 5.7 on the y-axis. | Then graph -1.5x going down on the y-axis and then go to the right on the x-axis.
Do the same for the other equation and you will get a solution of (2.7, 1.65) since they will intersect there.

Answer: 58 1/3 yards
Step-by-step explanation:
From the question, we are informed that a football team has a net yardage of −28 1/3 yards on a series of plays and that the team needs a net yardage of 30 yards to get a first down.
The number of yards that they have to get on their next play to get a first down would be calculated as:
= 30 - -28 1/3
Note that minus × minus = plus
= 30 + 28 1/3
= 58 1/3 yards
The answer is 4,000 ft squared because since the sides are 100 ft and 80ft then we need to multiply them which is 8,000 then divide that by 2 since it’s a triangle which is 4,000 ft squared.
