Step-by-step explanation:
You would add the red marbles and green marbles together and which would be 7 the get the total marbles would be 9 so the answer would be 7/9 or 78%
Answer:
Value of a in term of x = 8/x
Step-by-step explanation:
Given:
14 = ax + 6
Find:
Value of a in term of x
Computation:
⇒ 14 = ax + 6
Step 1; Subtract 6 from both side
⇒ 14 - 6 = ax + 6 - 6
We get step 2
⇒ 8 = ax
Divide x from both side and we get step 3
⇒ 8 / x = ax / x
Step 4
⇒ 8/x = a
Step 5
⇒ a = 8/x
Value of a in term of x = 8/x
Answer:
B
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant.
Using the distance formula
= | y - 6 |
Squaring both sides
(x + 2)² + (y - 4)² = (y - 6)² ← distributing
x² + 4x + 4 + y² - 8y + 16 = y² - 12y + 36 ( subtract y² - 12y + 36 from both sides )
x² + 4x + 4 + 4y - 20 = 0 ( subtract x² + 4x + 4 from both sides )
4y - 20 = - x² - 4x - 4 ( add 20 to both sides )
4y = - x² - 4x + 16 ( divide through by 4 )
y = -
x² - x + 4, that is
f(x) = -
x² - x + 4 → B
