Answer:
<h3>
x = 1/2</h3>
Step-by-step explanation:
-3x + 1 + 10x = x + 4
-1 -1
7x = x + 3
-x -x
6x = 3
÷6 ÷6
x = 1/2
Rectangle definitely not a parallelogram
Answer:
(h o g)(-1)) = 50
Step-by-step explanation:
Here, the functions are defined as
g(x) = 5x -2

Now, (h 0 g) (x) is defined as the function h of g(x).
⇒ (h 0 g) (x) = h(g(x))
now, by definition of both functions:
h(g(x)) = h(5x-2) = 
⇒
Putting x = -1 in the above expression,

Hence, h(g(-1)) = 50 or
(h o g)(-1)) = 50
