The answer to your question is C. -b/a
Answer: No
Step-by-step explanation:
No, because 4^2 is 16, 8^2 is 64, 10^2 is 100 and 16+64 = 80 and 80≠100
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve
Start by changing both into improper fractions.
Multiply the denominator and whole number, the add the numerator.
2 x 2 + 1= 5
2 1/2= 5/2
1 x 4 + 3= 7
-1 3/4= -7/4
Now do 5/2 multiplied by the reciprocal of -7/4 which is -4/7.
5/2 x -4/7= -20/14
Simplify to -10/7 by dividing by 2
Change it to a mixed number
Answer is -1 3/7
