1 gallon = 4 quarts.
2 gallons = 4 x2 = 8 quarts
She needs 8 quarts total and has 3 quarts.
8-3 = 5
She needs 5 more quarts.
Answer:
<u>y</u><u> </u><u>is</u><u> </u><u>5</u><u>.</u>
Step-by-step explanation:
Introduce log base 10:
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
The answer
y=−x^2−2x-24 is like the form of y=ax² +bx +c, to find the vertex we use the formula:
the x intercept according to the vertex is x=-b/2a, and the vertex V is a point such that V [-b/2a, f(-b/2a)]
the x intercept is x= -(-2) / 2(-1) =-1, and f(-1)= -1 +2 -24= -23
the vertex is V(-1, -23)
