What's the square root of 10 ?
   3²=9 and 4²=16
   So √10 is somewhere between 3 and 4 .

What's the square root of 47 ?
   6²=36 and 7²=49
   So √47 is somewhere between 6 and 7 .

The integers between √10 and √47 are 4, 5, and 6 .

Their sum is (4 + 5 + 6) = 15 .

First estimate the square root of 10, about 3.16
and then the square root of 47, about 6.85
now what are the integers in between 3.16 and 6.85:
4,5,6
now add them all
4+5+6
=15
Hope this helps.

Answer:

first person has a chance of 7/28 or 1/4

The second = 6/27 or 2/9

The third = 5/26

And the fourth = 4/25

multiplying these together you get 4 / 2340=

The solution of x in -6 + 3x - 9x^2 = -16 is $x = \frac{3 \pm \sqrt{369}}{18}$

<h3>How to solve the equation?</h3>

The equation is given as:

-6 + 3x - 9x^2 = -16

Add 16 to both sides

10 + 3x - 9x^2 = 0

Rewrite as:

9x^2 - 3x - 10 = 0

Solve for x using the quadratic formula

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

So, we have:

$x = \frac{3 \pm \sqrt{(-3)^2 - 4 * 9 * -10}}{2 * 9}$

Evaluate

$x = \frac{3 \pm \sqrt{369}}{18}$

Hence, the solution of x in -6 + 3x - 9x^2 = -16 is $x = \frac{3 \pm \sqrt{369}}{18}$

12) x-intercept: -18
y-intercept:-16

13) x-intercept: 6
y-intercept:10

Sorry I can't graph it for you but here are the equations in the slope-intercept form

11)y=-2/3x+8
12)y=-8/9x-16
13)y=-5/3x+10

Write the equation of the line in slope-intercept form.

finlep [7]

Answer
y=mx+b
y=2x-7

Explanation
m = the “common difference” between two points
In this graph, it’s 2 because every time the line moves across the x axis by 1, it increases in 2 in the y axis

b = the point that intercepts the y axis; the y-intercept
In this graph, the point intercepts the y axis at -7 (the y-intercept is -7)
