Answer:
Step-by-step explanation:
One is given the following equation;
The problem asks one to find the roots of the equation. The roots of a quadratic equation are the (x-coordinate) of the points where the graph of the equation intersects the x-axis. In essence, the zeros of the equation, these values can be found using the quadratic formula. In order to do this, one has to ensure that one side of the equation is solved for (0) and in standard form. This can be done with inverse operations;
This equation is now in standard form. The standard form of a quadratic equation complies with the following format;
The quadratic formula uses the coefficients of the quadratic equation to find the zeros this equation is as follows,
Substitute the coefficients of the given equation in and solve for the roots;
Simplify,
Therefore, the following statement can be made;
A. 2.
A radical is an expression which implies the use of a root.
There are three components of a radical expression:
(i) The root "√".
(ii) The radicand √"a".
(iii) The degree or index of the radical , when index of the radical is not shown then it understood to be a index of 2.
The index is the number used to indicate the degree of the root.
For the example , 10 is the radican and the index is not shown so it understood is 2.
Answer:
Step-by-step explanation:
This is a linear equation, y= mx + b, where y is the amount of money he has to spend, the value of b is 275 (the cost of the system), and 39x represents the cost of each game is x number of games is bought. We fill in and solve for x:
400 = 39x + 275 and
125 = 39x so
x = 3.2
Since he can't buy 3.2 games, the max number of games he can buy is 3.
The value of h(8) in h(x)= 6x - 17 is 31

What are functions:
Functions relate input and output. Therefore, a function takes elements from a set (the domain) and relates them to elements in a set (range).
h(x)= 6x - 17
Let's find h(8)
h(8) = 6(8) - 17
h(8) = 48 - 17
h(8) = 31
