To effectively determine the correct answer, it would be helpful to write this into an algebraic expression. We let x as the number. We do as follows:
<span>Four times the square of a certain number increased by 6 times the number equals 108.
4x^2 + 6x = 108
The numbers can be either of the following since the equation generated was a quadratic equation which has two roots.
x = 4.5
x = -6 </span>
A hole occurs when both numerator and denominator of a rational function have the same factor.
<u>Step-by-step explanation:</u>
While graphing rational function, it has to be converted into the lowest terms by factoring the numerator and denominator. If the numerator and denominator has the same factor, a hole is said to have occurred and to solve the rational function, you have to set the common factor to zero.
After you set it to zero and solve, you obtain the x value which can be then used to find out the value of y.
4. To simplify the expression, multiply J by 1 + the rate:
The expression would be j(1.05)
New price = 35(1.05) = 36.75
5. multiply the cost of each ( t-shirt and cd) by the number of cds bought:
Total = 12x + 7.50x
Simplify by adding the price of each together:
Total = 19.5x
Answer:
D
Step-by-step explanation:
By looking at this scatter plot we can see that the points generally go down when looking at the graph from left to right.
This somewhat straight line that is created is going in a negative direction.
That means that it is not only a linear finction, but is also negative.
