SAT Lines, angles, and triangles Question

Note: Figure not drawn to scale. Triangle TUV is dilated by a scale factor of $\frac{1}{2}$ to obtain triangle TUV'(not shown), where T corresponds to T' and U corresponds to U. What is the measure, in degrees, of angle V? B90 $${\mathrm{f}(\mathrm{x})=4x}^2+16\mathrm{x}+22$$ The function is defined by the given equation. The function h is defined by $h(x)=f(x)+9$ . What is the minimum value of $h(x)$ ? (A)31 (B)15 (C)7 $$7(5\mathrm{x})+9(8\mathrm{y})=189\text{\hspace{1em}(D)6)}$$ $$7(5\mathrm{x})-9(8\mathrm{y})=-819$$ The solution to the given system of equations is(x,y).What is the value of $5x+8y$ ?
