What is the x-coordinate of the point of intersection for the two lines below? (2x + y = -9
(2x - 5y =-3

From the graph, it is clear that the point of intersection is:

And the x-coordinate of the point of intersection for the two lines is:

Step-by-step explanation:

Given the system of equations

solving the system of equations

subtracting 2x+y = -9 from 2x-5y = -3

so

solving for y

Divide both sides by -6

Divide both sides by 2

Thus, the x-coordinate of the point of intersection for the two lines below will be:

Also, the graph is attached.

From the graph, it is clear that the point of intersection is:

And the x-coordinate of the point of intersection for the two lines is:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
