4 + 2x = 7
2x = 7 - 4 = 3
x = 3/2 = 1.5 inches
B involves direct variation.
y and x are directly proportional.

C. (5, 3)
Step-by-step explanation:
this point is within the answer area... look below at the graph of both linear inequalities
Answer:60
Step-by-step explanation:
a=13 b=13 c=10
Perimeter of =a+b+c
perimeter of =13+13+10
Perimeter of =36
S=36 ➗ 2
S=18
Area=√s(s-a)(s-b)(s-c)
Area=√18(18-13)(18-13)(18-10)
Area=√18(5)(5)(8)
Area=√(3600)
Area of =60
