The answer is 7 1/3 hope it helps!
a) Since the corresponding y-value is -0.6, hence the point (-0.8, -0.6) is a solution to the system of equations
b) since the corresponding x-value is not 1/3, hence the point (1/3, 2) is not a solution to the system of equation
In order to show if the given point corresponds to the given function, we will have to substitute the value of x into the function to see if we will have its corresponding y-value
For the point (-0.8, -0.6), substitute x = -0.8 into both functions as shown:
f(x) = 2x + 1
f(-0.8) = 2(-0.8) + 1
f(-0.8) = -1.6 + 1
f(-0.8) = -0.6
Simiarly;
y = -3(-0.8)- 3
y = 2.4 - 3
y = -0.6
Since the corresponding y-value is -0.6, hence the point (-0.8, -0.6) is a solution to the system of equations
For the point (1/3, 2), substitute x = 1/3 into both functions as shown:
x = (y+2)/2
x = (2+2)/2
x = 4/2
x = 2
Simiarly;
x + 2 = 3
x = 3-2
x = 1
Since the corresponding x-value is not 1/3, hence the point (1/3, 2) is not a solution to the system of equations

Answer:
Tomas
Step-by-step explanation:
Let's use miles per hour
Maren:<em> 60 miles/hour</em> (It's given to us)
Safiya: 120 miles/3 hours
Let's divide both by three to get to miles/hour.
120/3=40
<em>40 miles/hour</em>
Tomas: 84 miles/1.2 hours
Let's divide both by 1.2 to get to miles/hour
84/1.2=70
<em>70 miles/hour</em>
Cam: 75 miles/1.5 hours
Let's divide both by 1.5 to get to miles/hour
75/1.5=50
<em>50 miles/hour</em>
After comparing all the speeds we can conclude that Tomas drove the fastest.
