Answer:
x ≥ 7
Step-by-step explanation:
multiply both sides of the equation by 4
2x - 6
4 × ---------- ≥ 2 × 4
4
2x - 6 ≥ 8
2x ≥ 8 + 6
2x ≥ 14
2x 14
-------- ≥ ---------
2 2
x ≥ 7
Answer:
60 : 28, 90 : 42, 120 : 56, 150 : 70
here are some of the ratios equivalent to 30:14
give me brainliest please
multiple 30:14 or divide it by 2 to get the equivalent
A. Write a function f(x) to represent the price after the 80% markup.
<span>b. Write a function g(x) to represent the price after the 25% markdown. </span>
<span>c. Use a composition function to find the price of an item after both price adjustments that originally costs the boutique $150. </span>
<span>d. Does the order in which the adjustments are applied make a difference? Explain.
</span>
answers
<span>a) f(x) = 1.8x
b) f(x) = 0.75(1.8x)
c) f(150) = 0.75(1.8(150) = $202.50
d) No, it doesn't matter. The result is the same.

Answer:
A
Step-by-step explanation:
Note that
x² + 12x + 36 is a perfect square → (x + 6)², hence
= 
= (x + 6)
Hence
f(x) × g(x)
= (x + 6)(x³ - 11)
= 
- 11x + 6x³ - 66
= + 6x³ - 11x - 66 → A
Answer:
Step-by-step explanation:
Since, x-coordinate is negative and y-coordinate is positive, point will lie in the 2nd quadrant.
Answer is point P.
(-3, 6)
Point L represents the given coordinates.
Point P represents the given coordinates.
Since, x and y coordinates are positive, point will lie in the 1st quadrant.
Point Q represents the given coordinates.
Since, both x and y coordinates are negative, point will lie in the 3rd coordinate.
Point R represents the given coordinates.
