Answer:
z = 0.9778x^2 / y.
Step-by-step explanation:
When z varies with the square of x the equation is z = kx^2 where k = a constant.
If it also varies inversely with y the equation is z = kx^2/y.
When z = 4.4 , x = 3 and y = 2 we have:-
4.4 = k * 3^2 / 2
Multiplying by 2:
8.8 = 9k
k = 8.8 / 9
= 0.9778.
So the required formula is z = 0.9778x^2 / y.
Answer:
x= 14, x=-14
Step-by-step explanation:
All you have to do is combine like-terms:
x-3=11
x=11+3, x=14
and,
-x-3=11
-x=11+3
-x=14 multiply by -1 so x can be positive,
x=-14

Answer:
The third graph is correct for the inequality 2x + 3y > -3
Step-by-step explanation:
The slope of the graph is –2/3.
The y-intercept is –1
The area above the dashed be line is shaded.
To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.
For example: (1,1)
2(1) + 3(1) > –3
2 + 3 > –3
5 > –3 True.
P = 10
Explanation:
Combine like terms: -0.25p = -2.5
Divide both sides: by -0.25
Solution: p = 10
