Answer:
C. In step 2, Cindy should have multiplied both sides of the equation by 2.
Step-by-step explanation:
I'll go through the equation correctly, and then point out what would have happened.
3 = x/2 - 5
Add 5 to both sides. -5 and 5 cancel out.
8 = x/2
What Cindy should have done here is multiply by 2, not divide by 2. It is important to remember that you do the INVERSE operation to cancel out a number.
What would have happened here is that we have an extra step (though either way we still end up with x being 16.)
Correct Step 2:
Multiply both sides by 2. x/2 and 2x cancel out.
x = 16
Incorrect Step 2:
8/2 = (x/2)/2
4 = x/4
Multiply both sides by 4 (this would be the extra step!).
16 = x

Answer:
Step-by-step explanation:
To find f(a), replace x with a: f(a)=6−1a+15a^2
To find f(a+h), replace x with (a+h): f(a+h) = 6 -(a + h) + 15(a+h)^2
To find f(a+h)−f(a), expand f(a+h) as given above, and then subtract f(a):
f(a+h)−f(a) = 6 -a - h + 15(a^2 + 2ah + h^2) - [6 - a + 15a^2]
6 - a - h + 15a^2 + 30ah + 15h^2 - [6 - a + 15a^2]
This simplifies to: f(a+h)−f(a) = - h + 30ah + 15h^2
Answer:
Trombolysis
Step-by-step explanation:
Etymology is the study of the history of the words, the origin of them. In medical terminology roots, suffices and prefixes in Latin and ancient greek are commonly used to describe symptoms, deceases, etc.
Prefixes don't require further modification to be added to a word root because the prefix normally ends in a vowel or vowel sound, suffixes are attached to the end of a word root to add meaning such as condition, disease process, or procedure.
Considering this we look for the Latin of destruction, desintegration, "lyse", and then modify it as a termination suffix "-is", obtaining the termination "-lysis", and finally, we unify both words into one:
Trombolysis

Answer:
x = 4
y = 2
Step-by-step explanation:
The triangles being similar means the side ratios are the same.
AB/FD = BC/DE and AB/FD = CA/EF
12/3 = (3x+8)/5 and 12/3 = 28/(y+5)
Multiplying by 5, the first equation becomes ...
20 = 3x +8
12 = 3x . . . . . . subtract 8
4 = x . . . . . . . . divide by 3
__
Multiplying by (y+5)/4, the second equation becomes ...
y +5 = 28/4
y = 2 . . . . . . . . subtract 5
