Evaluate 2a+5fora=5

2. evaluate z/5+2 for z =10

3. solve 3b+7=-2

solve these because i have a f in the class

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots

100 points, hi, i’m not sure how to get the equation from the graph and table.

Let f(x)=2x and g(x)=2x. graph the functions on the same coordinate plane. what are the solutions to the equation f(x)=g(x) ?me asap
