Answer:
y = -5x/3 + 18
Step-by-step explanation:
The points can be written as;
(x,f(x))
where f(x) is same as y
So the points we have are;
(6,8) and (9,3)
We start by finding the slope or the line connecting the points
m = y2-y1/x2-x1 = (3-8)/(9-6) = -5/3
So now we have the general form of a linear equation as
y = mx + b
where m is slope and b is y intercept
We already have slope and we want to calculate y-intercept
Simply substitute one of the points
(9,3) in this case
9 for x and 3 for y
we have ;
y = -5x/3 + c
3 = -15 + c
c = 18
So the line equation is;
y = -5x/3 + 18
To find the measure of an interior angle of any regular polygon, we use the formula:
180 * (n-2) / n,
where n is the number of sides in the regular polygon.
Therefore, if there are 15 sides in the regular polygon, your answer would be
180 * (15-2) / 15,
or when simplified,
180 * 13 / 15
2340 / 15
156 degrees.
Thus, the measure of an interior angle of a regular polygon with 15 sides is 156 degrees.
I dont know if his is what you mean exactly but...
10, 20, 30, 40, 50, 60, etc..
<span> x = 3y - 8
</span>
Plug this in for variable x in equation [2]<span>
</span><span><span> [2] 3•(3y-8) + 2y = 31
</span><span> [2] 11y = 55
</span></span>
Solve equation [2] for the variable y
<span><span> [2] 11y = 55</span>
<span> [2] y = 5</span> </span>
// By now we know this much :
<span><span> x = 3y-8</span>
<span> y = 5</span></span>
<span>// Use the y value to solve for x
</span>
<span> x = 3(5)-8 = 7 </span>Solution :<span><span> {x,y} = {7,5}</span>

Question asks to estimate.
So do 300/40 to get 7.5
