Answer:
y = 4x + 3
Step-by-step explanation:
since we know how much he adds daily, we can put it next to 4, since we don't know how long he is going to save money. next you just add 3 as a checkpoint
The average rate of a function f(x) over an interval x = a and x = b is given by:
Given the function
The average rate of change from x = 1 to x = 2 is given by:
Idk if she's too young to learn cross multiply, but this is an easier method.
Multiply everything by 4 which cancels out the 4 on the left side.
36z-16/5 <= 7z + 2
Now multiply everything by 5, cancelling out the right side 5.
36z-16 <= 35z + 10
Solve the equation normally
z-16<=10
z<=36
1)
7/6d+4/3=-1/3
7/6d=-5/3
d=-5/3×6/7
d=-10/7
2)
5 1/2-u=9/4
11/2-u=9/4
22/4-u=9/4
13/4=u
3 1/4=u
3)
-m-7/8=-10
-m-7/8=-80/8
-m=-73/8
m=73/8 or 9 1/8
4)
2/7=4/5+9q
10/35=28/35+9q
-18/35=9q
q=-18/35×1/9
q=-2/35. Hope it help!
