    for the function, h(x) = bx - 22, b is a constant and h(-5) = -7. Find the value of h(5)

    h(-5) = -5b - 22

    Since we're given h(-5) = -7, we have:
    -5b - 22 = -7

    Typing this equation into our search engine, we get:
    b = -3

    So our h(x) equation is now:
    h(x) = -3x - 22

    The problem asks for h(5):
    h(5) = -3(5) - 22
    h(5) = 15 - 22
    h(5) = -37
