Answer:
x=12
Step-by-step explanation:
1/2*x =1/2x
1/2*2 =1
you need to get the constants on one side so subtract 1 on all sides to get 6=1/2x, then divide by 1/2 on all sides to get x= 12
F(x) = 10 - 4x
You must know that f(x) is technically "y" (the right side of the ( not this place ,this place ) )
A) (2, -18)
f(x) = 10 - 4x
-18 = 10 - 4(2)
WRONG!!
B) (18, -2)
f(x) = 10 - 4x
-2 = 10 - 4(18)
WRONG!!
C) (-2, 18)
f(x) = 10 - 4x
18 = 10 - 4(-2)
18 = 10 + 8 (two negatives numbers multiplied together=positive number)
18 = 18
Correct!
your answer is <span>C

B) 12 miles and 12 gallons. The answer is B because gallons and miles are 2 completely different types of measurement. If you look at A, C, D, they all have the same measurements. I hope this helped!
Step-by-step explanation:
2 consecutive numbers is X+X+2
so X+X+2=-8
ad the X and 2
2x=-8 (divide by 2 as -8 can divide by 2)
X=-4
so the two numbers are both -4
