y + 2 > 8 <em>subtract 2 from both sides</em>
y > 6
<h3>Answer: D. 7 > 6</h3>
3.
6 > z(10 - z)
A. z = 0 → 6 > 0(10 - 0) → 6 > 0 CORRECT
B. z = 1 → 6 > 1(10 - 1) → 6 > 1(9) → 6 > 9 FALSE
C. z = 2 → 6 > 2(10 - 2) → 6 > 2(8) → 6 > 16 FALSE
D. z = 3 → 6 > 3(10 - 3) → 6 > 3(7) → 6 > 21 FALSE

Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109
Answer:
c^2 = 6^2 -8
Step-by-step explanation:
The square of c is c^2; the square of 6 is 6^2. for the former to be 8 less than the latter, we must have ...
c^2 = 6^2 -8
