Answer:
A. The graph has two zeroes.
Step-by-step explanation:
A <em>zero of a polynomial</em> is a value of x that makes the polynomial equal to zero.
In other words, it is <em>an x-intercept</em>.
The graph crosses the x-axis twice, so there are two zeroes.
Answer: -10x+7.5
Step-by-step explanation:
First multiply -2.5(4x)= -10x and then -2.5x-3= 7.5 it should be -10x+7.5
400 children and 600 adults bought tickets.
Step-by-step explanation:
Given,
Cost of one child ticket = $14
Cost of one adult ticket = $32
Total attendance = 1000
Revenue generated = $24800
Let,
x be the number of children.
y be the number of adults.
According to given statement;
x+y=1000 Eqn 1
14x+32y=24800 Eqn 2
Multiplying Eqn 1 by 14

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 18

Putting y=800 in Eqn 1

400 children and 600 adults bought tickets.
