Answer:
Equation:
2(a+9) = a/2
Solve:
The umber is:
-12
Step-by-step explanation:
Equation:
2(a+9) = a/2
Solve:
2*a + 2*9 = a/2
2a + 18 = a/2
2a - a/2 = -18
4a/2 - a/2 = -18
3a/2 = -18
a = -18*2/3
a = -12
Check:
2(-12+9) = -12/2
2(-3) = -12/2 = -6
Original price = final price/(1-discount)
=75.39/(1-0.43)
=132.26
Answer:
The lenght of one side= 6
Step-by-step explanation:
The cost of fencing around the field for one meter = 15
The total cost = 360
The perimeter = 360 / 15 = 24 m
The lenght of one side= 6
( p = 4S)
so .... (s = p /4 )
24 = 4s
so .... s = 24/4 = 6
I hope it's right !!!!!
Pick any point and then plug the domain and range into x (domain value) and y (range value).
Answer:
y=-5/9x+7
Step-by-step explanation:
1. Use the two points and plug them into the slope formula to figure out the slope.
y2-y1/x2-x1
2-7/9-0 = -5/9
2. Pick one of the coordinates and use the x and y points and the slope to put them into point-slope form
y-y1=m(x-x1)
y-7=-5/9(x-0)
3. Distribute and simplify.
y-7=-5/9x-0
y=-5/9x+7
