Answer:

y-5=2.5(x-2)

Step-by-step explanation:

Since we know the slope, we know what x is. x is equal to 2.5. Therefore, the equation will be y=2.5x+?. The y-intercept on this graph is 0. This is because the only point on the y line is (0,0). Therefore, the y-intercept is 0. Therefore, the equation is y=2.5x.

What is the factorization of the trinomial below? 4x2 + 20x - 24

Ivenika [448]

Hey there!

$4x^{2} +20x -24$
We can first factor out the 4 (bring it outside the parenthesis)

$4( x^{2} +5x - 6)$
Now have a closer look between the parenthesis, because this expression can be factored as well. We're looking for two different numbers with a product of -6 and a sum of 5. Hence, we find the numbers 6 and -1

$4(x-1)(x+6)$
~ Hope this helps you!

PLS HELP <br> what would be the equation for this one?

____ [38]

Answer:

x^2 + y^2 = 25

Step-by-step explanation:

The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius.

We can see that the center is (0, 0) by looking at the graph, and the radius is 5 because it is marked. Plugging these in we get:

x^2 + y^2 = 25
