Answer:
(m) increased, (b) unchanged. g(x)
(m) decreased, (b) unchanged. m(x)
(m) unchanged, (b) increased. h(x)
(m) unchanged, (b) decreased. n(x)
f(x): m = -1/2 b = 2
g(x): m = 1/3 b = -3
h(x): m = 2 b = 0

Answer:
The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch
Step-by-step explanation:
Let
x ----> the number of bags of hardwood mulch sold
y ----> the number of bags of pine bark mulch sold
we know that
A local boys club sold 136 bags of mulch and made a total of $400
so
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
Using a graphing tool
The solution is the point (52,84)
see the attached figure
therefore
The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch
In the equation 50/3=75/x
multiplying both sides by x we get:
50x/3=75
multiplying both sides by 3 we get
50x=225
this implies that the mistake that Joanie made was that she forgot to multiply 75 by 3.
thus
50x≠75.
Answer:
11 > n > 4
Step-by-step explanation:
Given any two sides of a triangle, we now that the sum of such sides MUST be greater than the measure of the remaining side. This is, given the three sides a, b and c, it must be that:
a + b > c
a + c > b
b + c > a
For our case:
7 + 4 > n (1) ---> 11>n
7 + n > 4 (2)
4 + n > 7 (3)
The 1 inequality says that the n side MUST be less than 11.
Now, pick the (3) inequality and subtract 4 in both sides:
4 + n -4 > 7 - 4
n > 3
So, the n side must be grater than 3.
Thus, the solution is:
11 > n > 3
As we are working with integers we now that the grater integer larger than 3 is 4, and the greater integer less than 11 is 10. So, the side must be equal or greater to 4 and equal or less than 10:
10 >= n >= 4
