No its not a function :)
<span>to find the inverse function first expand those brackets </span>
<span>you'll get </span>
<span>f(x)= x^2 - 2x^2 - 2x^2 = 4x^2 </span>
<span>f(x)= x^2 - 4x^2 + 4x^2 </span>
<span>f(x)= x^2 or y=x^2 </span>
<span>to find the inverse, swap x and y around. then make y the subject again </span>
<span>y=x^2 </span>
<span>x=y^2 </span>
<span>Root of x=y </span>
<span>now put -1 into x </span>
<span>it wont work because roots cannot have negative numbers </span>
<span>answer is no</span>
6500 + 125.25t = 5292 + 200.75t
6500 - 5292 = 200.75t - 125.25t
1208 = 75.50t
1208 / 75.50 = t
16 = t
they both charge the same when using 16 tons
they both cost $ 8504
Step-by-step explanation:
let x be the another angle
so
x+40=90
x=90-40
x=50
The measure of missing angle is 50
hope it helps
