14+ 13y - 13y = 20y - 13y -21 (taking away the smallest y value from both sides)
14 = 7y - 21
14 + 21 = 7y - 21 +21 (+21 on both sides to remove -21 if we do -14 then we will have nothing on other side)
35 = 7y
35/7 = 7y/7 (dividing 7 on both sides)
5 = y
answer is 100% correct no doubts. hope it helped you.
Answer:
25.1cm
Step-by-step explanation:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer:
0.75%
Step-by-step explanation:
Convert the fractions and then multiply by 100.
You determine whether the parabola opens upward, with a positive x^2. It opens downward with a negative x^2.
f(x) is a maximum
g(x) is a minimum
