4/5, because to simplify a decimal, you can divide the numerator by the denominator. 4 divided by 5 is 0.8

Answer:

4/5

Step-by-step explanation:

4/5 = 0.8

1/7 = 0.14285714

17/13 = 1.30769231

19/6 = 3.16666667

Hope this helps! In order to convert a fraction to a decimal, you just divide the numerator by the denominator. :)

Answer:

21/4 = 5.25

Step-by-step explanation:

You want the sum of the x-values that are solutions to ...

21x -4x² = 5

4x² -21x +5 = 0 . . . . . subtract the left side, rearrange to standard form

x² -(21/4)x +5/4 = 0 . . . divide by 4

In this form the sum of the x-values that solve this equation is the opposite of the x-coefficient. That sum will be 21/4 = 5.25. (The attached graph confirms this result.)

Consider a quadratic with roots p and q. It factors as ...

(x -p)(x -q) = 0 = x² -(p+q)x +pq

That is, the x-coefficient is the opposite of the sum of the roots p and q.

Sketch the graph of the given function. Then state the function’s domain and range. f(x)= 1/2(5)^x+3

balandron [24]

Answer:

Graph of the following function is attached with the answer.

Domain : ( - ∞ , + ∞ )

Range : ( 3 , + ∞ )

Step-by-step explanation:

$f(x)=\frac{1}{2}x^{2}+3$

Domain of any quadratic equation is from negative infinity to positive infinity under no restrictions.

So, Domain : ( - ∞ , + ∞ )

The Range of any function can be calculated easily if there is just one term with variable. The method to find Range by that method is explained with the example as follows:

Range of x : ( - ∞ , + ∞ )
Range of $\textrm{x}^{2}$ : [ 0 , + ∞ ) as every square number is more than or equal to zero.
Range of $\frac{1}{2}\textrm{x}^{2}$ : [ 0 , + ∞ ) as 0/2 = 0 and ∞/2 = ∞.
Range of $\frac{1}{2}\textrm{x}^{2}+3$ : [ 3 , + ∞ ) as 0 + 3 = 3 and ∞ + 3 = ∞.
