Answer
<h2>4</h2>Step-by-step explanation:
Given,
r = 10
Let's create an equation,
plugging the value of r
Multiply the numbers
Move 5s to L.H.S and change its sign
Similarly, Move 30 to R.H.S and change its sign.
Calculate
The difference sign ( - ) should be cancelled on both sides
Divide both sides of the equation by 5
Calculate
The value of s is 4.
Hope this helps..

Table (A) represents the parabola y = x² - 6x in which the parabola opens and the y-intercept is (0, 0) table (A) is the correct choice.
<h3>What is a parabola?</h3>It is defined as the graph of a quadratic function that has something bowl-shaped.
We have the tables shown in the picture.
We know the quadratic form of a parabola is:
y = ax² + bx + c
If a > 0 the parabola opens
In the equation:
y = x² - 6x
1 > 0 the parabola opens and y-intercept is:
y = 0 (plug x = 0 in the given equation)
a = 1, b = -6, and c = 0
Thus, table (A) represents the parabola y = x² - 6x in which the parabola opens and the y-intercept is (0, 0) table (A) is the correct choice.
