Answer:
The inverse is 5x+3
Step-by-step explanation:
y = (x-3) /5
Exchange x and y
x = (y-3)/5
Solve for y
Multiply each side by 5
5x =(y-3)/5 *5
5x = y-3
Add 3 to each side
5x+3 =y-3+3
5x+3 =y
The inverse is 5x+3
Slope = rise/run
the ladder "rises" to 13 feet above the ground
the ladder "runs" 3 feet from the base of the ladder to the tree
so: slope = rise/run = 13/3
Answer:
x-1
Step-by-step explanation:
Area= x^2+4x-5
Width= x+5
Area= Length*breadth
x^2+4x-5=length*x+5
Length=x^2+4x-5/x+5
Therefore, length= x-1
Answer:
The best buy is the 0.74 kg box
Step-by-step explanation:
Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store.
We find the unit price for 1 box
a) The 0.425 kg box was on sale for $3.59
= 1 kg = $3.25/0.425
= $7.6470588235
b) the 0.74 kg box was on sale for $4.88,
1 kg = $4.88/0.7$
= $6.5945945946
c) the 0.95 kg box was on sale for $7.29.
1 kg = $7.29/0.95
= $7.6736842105
Which box of cookies was the best buy?
The best buy is the 0.74kg box because 1kg of this box has a lesser price compared to the others.
