I would start by saying how much I enjoyed this lesson and how it has helped me in many ways I would also like to state how it was difficult at first but once I started to understand it, it became really easy and would like to thanks the teacher for teaching it.
The measure of B’C’ is 18 inches
Answer:
Solution x = - 1
Step-by-step explanation:
3 / (2x+1) = 9 / 3x
Cross multiply
3(3x) = 9(2x + 1)
Distributive property
9x = 18x + 9
Subtract 18x from both sides
-9x = 9
Divide both sides by -9
x = -1
Answer:
-25
Step-by-step explanation:
(1) y = -2x²
(2) y = 2x² + k Subtract (1) from (2)
0 = 4x² + k Subtract 4x² from each side
k = -4x²
The parabolas are <em>symmetrical about the y-axis.</em>
Segment AB = 5, so x = +2.5 and x = +2.5.
k = -4(±2.5)² = -4 × 6.25 = -25
