The answer is Ms Hernandez can bring up to 6 people to the zoo.
x - <span> the number of people that she can bring to the zoo
</span><span>The parking will cost $7: a = 7
</span><span>Admission tickets will cost $15.50 per person: b = 15.50x
She can spend on parking and admission tickets </span><span>$100:
a + b </span>≤<span> 100
a = 7
b = 15.50x
7 + 15.50x </span>≤<span> 100
15.50x </span>≤<span> 100 - 7
15.50x </span>≤<span> 93
x </span>≤<span> 93 / 15.50
x </span>≤ 6
Answer:
Here are the answers and walkthrough to Stupid Test Level 19 Question 12 – Carrie has 0.125 more than Larry and Larry has 3/4 more than Harry. Between them Harry, Larry and Carrie have 151. How many does Harry have? Carrie=63, Larry=56, Harry=32.
Step-by-step explanation:
9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9
This is a bad question. It should really be asking about the solutions of f(x)=0 (an actual equation) or the <em>zeros </em>of f(x).
The zeros of a function f(x) are the xs where f(x)=0. That means where the curve intersects the x axis. That's (-4,0) and (2,0) on the graph.
Answer: C (-4,0), (2,0)
-79, -55, 18, 44, 101, 143
