Given:
The graph of a polynomial.
To find:
The number of roots of the polynomial lie between x = -4 and x = 3.
Solution:
From the given graph it is clear that the graph is a downward U-shaped curve. It means the given graph represents a quadratic polynomial.
The graph of the polynomial is below the x-axis immediate before x=-2 and above the x-axis immediate after x=-2. It means the graph intersect the x-axis at x=-2.
The graph of the polynomial is above the x-axis immediate before x=2 and below the x-axis immediate after x=2. It means the graph intersect the x-axis at x=2.
Since the graph of the polynomial divides the x-axis two times between x = -4 and x = 3, therefore the two roots of the polynomial lie between x = -4 and x = 3.
Answer:
x (number of glass of milk) =11, and y (number of snack bar) =12
Step-by-step explanation:
4x+3y=80
3x+4y=81
Answer:
-11a
Step-by-step explanation:
To get the answer, you must combine these terms because they are like terms. -5a+a = -4a, and -4a-7a = -11a. Therefore, the answer is -11a.
To solve the given operation firat we take LCM for both terms.
As denominator of first term is 3 and second term is
Therefore, the Lcm is
Now solving and making same denominator for each term
On multiplying we get
Now solving other term
On multiplying we get
Now solving the expression by putting the values
On solving we get
There denominator of the expression is
