5/15 simplified is 1/3
Welcome!
The ordered pair (-1, 6) is the solution to the system of equations.
Step-by-step explanation:
Given equations are;
3x+2y=9 Eqn 1
y=4x+10 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
Dividing both sides by 11
Putting x=-1 in Eqn 2
Solution: (-1, 6)
The ordered pair (-1, 6) is the solution to the system of equations.
Answer: D
Step-by-step explanation:
D = m/v
D*m = m/v * m (m's cross out)
Dm = v

$480-$120=$360
$360/24=15
Before we solve, let's define what a scale factor is. A scale factor is a certain number that can be multiplied or divided by to get a smaller or bigger image that's similar to the current image.
We have 48 by 36 as our original.
It has been reduced to an 8 by 6.
This means we must divide.
Before we get into any complicated ideas, if any, let's try a simple trick.
Divide 48 by 8 and 36 by 6. This should give us a scale factor if they give us the same quotients.
48 / 8 = 6
36 / 6 = 6
It turns out our scale factor is 1/6 (the same as dividing by 6).
The answer cannot be 1/8 because 36 / 8 doesn't give us 8 as a quotient.
The answer also cannot be 6 because we'd have to mutliply our current sides by 6 to get the new image, which it was the opposite.
By elimination and work shown, A.) 1/6 is the correct answer.
I hope this helps!
