Answer:
A. 3x+50 ≤ 100; 16 people
Step-by-step explanation:
If x represents the number of people at Berta's party, then the cost of food is 3x. Added to the $50 cost of room rental, the total charge Berta must pay will be ...
3x +50
She wants this to be at most $100, so her inequality is ...
3x +50 ≤ 100
Berta can solve this by subtracting 50, then dividing by 3.
3x ≤ 50
x ≤ 16 2/3
Since x represents a number of <em>people</em>, and it is not possible (or desirable) to have 2/3 of a person show up, the maximum number of people that can attend Berta's party is 16.
-50 meters would be the answer.
Answer:
7.05 seconds
Step-by-step explanation:
X intercept = -1, y = 0 (-1, 0)
<span>y intercept = 2, x = 0 (0, 2)
</span>
slope between (-1, 0) and (0, 2):
slope = (2 -0)/(0 - -1) = 2/1 = 2, m = 2
Using point (-1, 0) x₁ = -1, y₁ = 0
y - y₁ = m(x - x₁)
y - 0 = 2*(x - -1)
y = 2(x + 1)
y = 2x + 2
