Answer:
x = 12.1
Step-by-step explanation:
20 − (z + 7) = 0.9
Distribute the minus sign
20 -x -7 = .9
Combine like terms
13 -x = .9
Subtract 13 from each side
-x = -12.1
x = 12.1
Solve for l.
p=2(l+w)
Flip the equation.
2l+2w=p
Add -2w to both sides.
2l+2w+−2w=p+−2w
2l=p−2w
Divide both sides by 2.
2l/2=p−2w/2
l=1/2p−w

B is the answer.
Hope it helps!
The relation that is also a function is described as follows:
A nonlinear function on a coordinate plane vertex at (minus 3, minus 2) passes through (minus 7, 0), and (minus 6, minus 4).
<h3>When a relation is a function?</h3>
A relation is a function if each value of the input is mapped to only one value of the output.
In this problem, we have that:
- For the dot plot graph, input 2 is mapped to -3 and -4, hence it is not a function.
- In a circle graph, each value of x is mapped to two values of y, hence it is not a function.
Hence a function is given by:
A nonlinear function on a coordinate plane vertex at (minus 3, minus 2) passes through (minus 7, 0), and (minus 6, minus 4).
