This is not always true. Consider $a=3$ . Then $3^2-3=9-3=6$ is even, but $a$ is odd.

PLEASE ANSWER ALL

Step-by-step explanation:

The axis of symmetry: is the line that makes the parabola split in exactly half and lines up with the vertex. For that parabola x=1 is the line of symetry.

The vertex is where the minimum of the graph is, on this graph you can eyeball it to be (1,-9)

The x-intercept is where y is 0 so that's where the lines intersex with the x-axis. (-2,0) and (4,0)

The y-intercept of the function is where x is 0 and where the parabola intersects with the y-axis. On this graph it would be (0,-8)

Hope that helps :)

Find the measure of the largest angle in the triangle shown . PLS HELP

Andre45 [30]

Answer:

72°

Step-by-step explanation:

So the three angles of a triangle always add up to 180°. This means that

$15x + 21x + 24x = 180$

This becomes:

$60x = 180$

And solves as:

$x = 3$

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

$24x = 24(3) = 72$

The measure of the largest angle in the triangle is 72°.
