Hello there!
8 - 2x = -8x + 14
Let's start by subtracting 8 to both sides
8 - 2x - 8 = -8x + 14 - 8
-2x = -8x + 6
Let's add 8x to both sides
-2x + 8x = -8x + 6 +8x
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
The correct answer is option D
I hope this helps!
For elimination, multiply one whole equation by negative one (-1), then add or subtract according to your signs. After that, it will be a one-step equation.
3x + 4y = 19 3x + 4y = 19 3x + 4y = 19 -2y = -14 y = 7
3x + 6y = 33 -1 (3x + 6y = 33) -3x - 6y = -33 -14 / -2
Then you would go back and substitute the value of (y) back into either equation and then solve for the remaining variable (x). Finally, use both values to make an ordered pair.
3x + 4y = 19 3x = -9 x = -3 (-3 , 7)
3x + 4(7) = 19 (-9 / 3)
3x + 28 = 19
Good Luck
The answer is 18^8 because u add exponents
f(x) increase by a factor of 3
Explanation:
Given that f(x)= 3* and the interval is x=4 to x=57
Now we put the value for x is 4 to 57 then value of f(x) increase with the multiply of 3.
Because the x is multiplied with 3 i.e., 3*
So f(x) increase by a factor of 3.
If we put x=4, then f(x)= 12 (∵ 3×4=12)
If we put x=5, the f(x)= 15 (∵ 3×5=15)
If we put x=6,the f(x)= 18 (∵ 3×6=18)
similarly., values of x= 7,8,9,...155.
Then,
If we put x=56, the f(x)=168
This process will continue until f(x)=171 for x=57.
For this question we can solve it by setting up a proportion:
Now we can solve for x to find the total distance between the towns. Let's cross multiply and solve for x:
So now we know that
the total distance between the towns is 42.5 miles.
