The domain is the set of x-values of a function. The range is the set of y-values of a function.
You are told that the domain, or x-values, are -8, -6, -3, -2, and 2. To find the range, you just need to plug in each of the x-values into the function <span>y = -3x + 7 and find the value of y.
1) When x = -8:
</span><span>y = -3x + 7
y = -3(-8) + 7
y = 24 + 7
y = 31
2) When x = -6
</span>y = -3x + 7
y = -3(-6) + 7
y = 18 + 7
y = 25
3) When x = -3
y = -3x + 7
y = -3(-3) + 7
y = 9 + 7
y = 16
4) When x = -2
y = -3x + 7
y = -3(-2) + 7
y = 6 + 7
y = 13
5) When y = 2
y = -3x + 7
y = -3(2) + 7
y = -6 + 7
y = 1
The range is {31, 25, 16, 13, 1}.

Answer: {31, 25, 16, 13, 1}
Answer:
its no solutions
Step-by-step explanation:
because u solve the 1st varibles in one of the equations,then subsitute the results into the other equations
-4/7 (decimal form (.571))
1/2(5-7x)=8-4x+6
-7/2x+5/2=-4x+14 Simplify both sides
1/2x+5/2=14 Add 4x to both sides
1/2x=23/3 Subtract 5/2 on both sides
2*(1/2x)=2*(23/2) Multiply both sides by 2
x=23 - Final Answer

Answer:
12.8 km
Step-by-step explanation:
1mile = 1.6 km
To get to 8 miles you would times the 1.6 by 8
1.6*8=12.8 Kilometers
