The value of the expression for the given values of a and b is -1
<h3>Evaluating an expression</h3>
From the question, we are to evaluate the given expression for the given values of a, b, and c
The given expression is
a + b
The given values are
a = 4,
b = -5,
and
c = -8
To evaluate the given expression for the given values of a and b, we will put the values of a and b into the expression,
That is,
a + b becomes
4 + -5
= 4 -5
= -1
Hence, the value of the expression for the given values of a and b is -1

Step-by-step explanation:
Given:
Amount = £399
Ratio of amount gets Ann to Bill = 2 : 9
Chloe and Dave get 2.5 times the amount Ann gets.
To find:
The amount of money that Bill gets.
Solution:
Let Ann, Bill, Chloe and Dave gets 2x, 9x, 2.5 × 2x and 2.5 × 2x.
![2x + 9x + (2.5 \times 2x) + (2.5 \times 2x) = 399](https://tex.z-dn.net/?f=2x%20%2B%209x%20%2B%20%282.5%20%5Ctimes%202x%29%20%2B%20%282.5%20%5Ctimes%202x%29%20%3D%20399)
![2x + 9x + 5x + 5x = 399](https://tex.z-dn.net/?f=2x%20%2B%209x%20%2B%205x%20%2B%205x%20%3D%20399)
![21x = 399](https://tex.z-dn.net/?f=21x%20%3D%20399)
Divide by 21 on both sides.
![$\frac{21x}{21} =\frac{399}{21}](https://tex.z-dn.net/?f=%24%5Cfrac%7B21x%7D%7B21%7D%20%3D%5Cfrac%7B399%7D%7B21%7D)
x = 19
Amount that Bill gets = 9x
= 9 × 19
= 171
The amount of money that Bill gets £171.

Step-by-step explanation:
Answer:
The easiest method is to find the x-intercepts of the quadratic function by substituting y=0 in the function and solving it to find the possible values of x. The number of all possible values of x is the number of x-intercepts of the graph.
