Consider the function f(x)= (x+4)(x-2) what is the equation of the axis of symmetry

Mathematics

8 0

if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation

\bf 0 = (x+4)(x-2)\implies \begin{cases} 0=x+4\implies &-4=x\\ 0=x-2\implies &2=x \end{cases}

now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.

well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys

-4------------(-1)------------2

so the vertex is at x=-1, namely the axis of symmetry is x = -1.

10+x &gt; 17 solving one step inequalities
pogonyaev

Answer:

x > 7

Step-by-step explanation:

you move over the 10 to the left and it becomes negative.

x > 17 - 10

so then you subtract the 17 - 10 and you would get 7.

x > 7

Please give me the correct answer!!!
Neko [114]

Answer:

Step-by-step explanation:

this one is tricky    so b/c the lines are at 90 degees we know that the arcs are similar so set up the parts of the arcs equal to 360 degrees

360 = 130  + 130  + x + x

see each part of the circle ?

then use your mad algebra skilz

100 = 2x

50 = x  

:)  nice.. when I do the math , it seems easy , huh :DDD
