Answer:
C.) -7/5
Step-by-step explanation:
To subtract fractions, we need to have common denominators. So first, we will change -1 1/5 to -6/5.
Now we will change the denominator of both -6/5 and 1/2 to 10.
We now have:
5/10 and -12/10
5-12=-7
So the answer would be -7/5
If we want to use the number line, we would first find 5/10 (1/2) on the graph and count down (to simulate subtraction) 12 units since we are subtracting by 12. :))
The problem in the picture would be
x^2+10x+21
A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.
Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b
-2 = (3/4)*(12) + b
You'll get b= -11
So the equation of the parallel line intersecting the point given is y= 3/4x -11.
I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.
C is correct answer I think :)
