Identify the type of function represented by f(x)=4.3^x

Suppose a least-squares regression line is given by modifyingabove y with caret equals 4.302 x minus 3.293. what is the mean value of the response variable if xequals20?

Ineed with angles and the measure of them i have abc a is 65 and b is (3x-10) and c is (2x) find the value of x

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a> 1
