The first thing you would do is switch the x and y (B).
For example, to find the inverse of y = 2x + 8:
1. Swap x and y
x = 2y + 8
2. Solve for y (set the equation equal to it):
x - 8 = 2y
y = (x - 8) ÷ 2
= 1/2x - 4
Answer:
A
Step-by-step explanation:
<span><span /><span>In this problem, it is stated that Darcy uses
block in order to show the value of the number.
Place value blocks are commonly used to help or support the students to
investigate the place value of the given number. It would be easy for Darcy to
use a material to know the number she’s looking for.
It says here that she used 4 thousand blocks and 500 hundred blocks.
Thus, the number she’s looking for is:
=> 4thousand + 5hundred
=>4000 + 500
=> 4500</span></span>
Area = 80 sq yards
height = 10 yards
80 = .5* 10 * base
base = 16
