Answer:
Step-by-step explanation:
domain is the input, or the x values, range is the output, or y values
x goes from 0 to 40 so that's the domain
y goes from 0 to 4 so that the range
A = 180 - 143 = 37
b = 143
c = a = 37
e = a = 37
f = 90 - 37 = 53
d = 180 - 85 - 37 = 58
g = 48
h = 180 -48 -48 = 84
k = 180 -84 = 96
m = 180 - 58 - 96 = 26
p = 180 - 26 - 85 = 69
r = 180 -69 = 111
s = p = 69
I’m pretty sure there’s not supposed to be a second parenthesis after the - 6
You would subtract 1/5 on the side with x and do the same to the other side so x would 11 + 1/5 so 11.20 i think
The value of the function when x = 1/2 is r(1/2) = 3 2/3
<h3>How to evaluate the function?</h3>
The equation of the function is given as:
r(x) = -2/3x + 4
The equation r(x) = r(1/2) means that
x = 1/2
Substitute x = 1/2 in r(x) = -2/3x + 4
r(1/2) = -2/3 * (1/2) + 4
Evaluate the product
r(1/2) = -1/3 + 4
Evaluate the difference
r(1/2) = 3 2/3
Hence, the value of the function when x = 1/2 is r(1/2) = 3 2/3
