Algebraic Derivations

Please see the attached sheet with 4 equations. From these 4 equations, I am to get expressions for B/A and C/A. The hint I get is to express F and G in terms of C from the last 2 equations, and use this to obtain relations between B/A and C/A. But I'm having particular trouble in expressing F and G in terms of C..


1.) which quadrant or axis would this lie in? X+2Y=1:(0, ? ), (-2, ? ), (2, ? ) 2.) what is the slope and y intercept for this? y= -x+5 3.) what would this look like on a graph? x=9 4.) What is the equation if it is written in standard form using only intergers as the coefficients? the line through ( -

Solve the following for x

Solve the following for x: 4(2^x)=56 in the order of operations Pemdas requires that exponentation takes precedence over multiplication, so we cannot multiply 4*2 without first evaluating 2^x, but we could divide both sides by 4. Also remember x is an exponent and we have to take logarithmic of both sides to bring the exponent
