Answer: The number 0
x^2 + 8x - 4 = x^2 + 8
8x - 4 = 8 ... subtract x^2 from both sides
8x = 12 .... add 4 to both sides
x = 12/8 .... divide both sides by 8
x = 3/2 ... reduce
x = 1.5 .... convert to decimal form
Now plug x = 1.5 into the expression 2x-3 and simplify
2x-3 = 2*1.5-3 = 3-3 = 0 which is the answer
$153.37 x 4 = $613.48
$613.48 / 7 = $87.64
i believe $87.64 is your answer
Answer:
{2, 4, 6}
Step-by-step explanation:
the domain is the interval or set of valid x (input) values.
the range is the interval or set of valid y (result) values.
all we need to do is use the given x values in the functional definition and collect the result values. that is the range.
x = -1
y = 2×-1 + 4 = 2
x = 0
y = 2×0 + 4 = 4
x = 1
y = 2×1 + 4 = 6
X= 3 y=3
(3)2x+y=9
4x-3y=3
6x+3y=27
4x-3y=3
——————
10x=30

x=3
2(3)+y=9
6+y=9
-6. -6
y=3
