Let Tritt's age = t & Jan's age = 2t - 3
if the sum of their ages equals 30 then..
combine terms and simplify
now simply divide
and to find Jan's age just plug 9 in
Jan's age = 15
Tritt's age = 9
I am confused, what is your question? It help me help you better if I know what the question is.
The graph of f(x) = x^2 has only one x-intercept since its vertex is at the origin, (0,0) and it opens up. When comparing the graph of <span>g(x) = -x^2 -5 with the graph of f(x) = x^2, g(x) is the graph of f(x) first reflected in the x-axis and then translated 5 units down. The graph of g(x) has no x-intercepts since its a parabola that opens downward (result of reflection in x-axis) and its vertex at (0,-5) is situated below the x-axis.</span>
Step-by-step explanation:
f(-5)=-5(-5)²+4
f(-5)=5(25)+4
f(-5)=125+4
f(-5)=129
