If (ax - 4)(bx + 7) = 10xsquared + cx – 28
for all values of x, and a + b = 7, then
there are two possible values of c.
what is one of those two possible values of c ?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

answer: it's upside down and i can't read it

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
