Answer:
b)
The point is (-1,5) and (0,0) also satisfies the given inequalities
The solution of the given inequalities
(x, y) = (4 , -2 )
Step-by-step explanation:
<em>Step(i):</em>-
Given system of equations are
3x + 2y < 8
-5x - 9y > -2
The solution of the given equations are
3x + 2y = 8 multiply '5'
-5x - 9y = -2 multiply '3'
15 x + 10 y = 40 ...(i)
-15x - 27 y = -6.....(ii)
Adding (i) and (ii) , we get
- 17 y = 34
y = -2
Substitute y = -2 in equation 3x + 2y =8
3x - 4 =8
3x = 12
x =4
The solution of the given system of inequalities
(x, y) = (4 , -2 )
<u><em>Step(ii)</em></u>:-
3x + 2y < 8
-5x - 9y > -2
The point is (-1,5)
-3 + 10 < 8
7 < 8
5 - 45 > -2
-40 > -2
The point (0,0) also satisfies the given inequalities
Final answer :-
The point is (-1,5) and (0,0) also satisfies the given inequalities

<h3>What is Sound intensity?</h3>
Sound intensity, serves as the power that is been carried by sound waves per unit area and this is usually in the direction perpendicular to that area.
we were given the function 
r represent the Distance from the source of sound
P represent the Power of the sound
when there is increase in the distance from the source the intensity moves to zero.
we can see that there is is an inverse proportion between the Intensity and the distance r which implies that The intensity decreases when the distance increases.

Answer:
<em>56 ounces </em>= <em>7 cups.</em>
Step-by-step explanation:
Y-3=1/2(x+2)
To find the y-intercept, we must first get the equation in slope intercept form. Start off by distributing 1/2 into the parentheses.
y-3= 1/2x+1
Add 3 to both sides
y= 1/2x+4
The slope is whatever is in front of x, in this case, 1/2. The y-intercept is the number after that which would be 4
