Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
Answer:
The sum of three times a number and 4
Y=mx+b
m=slope
slopes of parallel lines are the same
y=3/4x+2
the slope is 3/4
the slope of a line parallel to that is 2/3
Answer:
2 2/3
Step-by-step explanation:
hope this helps :)
don't be afraid to ask questions
Recall the angle sum identities:
Now,
Divide through numerator and denominator by 
to get
Next, we use the fact that 
lie in the first quadrant to determine that
So we then have
Finally,
