Question 10(multiple choice worth 5 points)

(03.07a lc)

a system of two equations is shown below:

equation c: a = 2b + 7
equation d: a = 5b − 3

what value of a can be substituted into equation d to solve the system of equations?

a 2b
b 5b
c 5b − 3
d 2b + 7

The graph of f(x), shown below, resembles the graph of g(x) = x2, but it has been changed somewhat. which of the following could be the equation of f(x)?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
