Answer: Second option: (4,0) and (-9,0)

f(x)=x^2+5x-36

The x-intercepts of the graph of a function f(x) are the values of the variable x that makes f(x)=y equal to zero. To find these values we only have to equal f(x)=y to zero:
f(x)=y=0
x^2+5x-36=0

Factoring the polynomial:
(x+9)(x-4)=0

Using that if a b=0, then: a=0 or b=0
with a=x+9 and b=x-4

x+9=0 or x-4=0

Solving for x:
x+9-9=0-9 or x-4+4=0+4
x=-9 or x=4

Then the x-intercepts are the poitns (x,y)=(x,0):
(4,0) and (-9,0)

Consider the following system of equations. -10x2-10y2=-300 5x2+5y2=150 Which statement describes why the system has infinite so
scoundrel [369]

Answer:

The equations represent circles that result in the same graph.

Step-by-step explanation:

we have

-10x^{2}-10y^{2}=-300

Divide by -10 both sides

x^{2}+y^{2}=30 -----> equation A

This is the equation of a circle centered at origin with radius r=\sqrt{30} \ units

and

5x^{2}+5y^{2}=150

Divide by 5 both sides

x^{2}+y^{2}=30 -----> equation B

This is the equation of a circle centered at origin with radius r=\sqrt{30} \ units

equation A and equation B are equal

therefore

The system has infinite solutions, because the equations represent circles that result in the same graph.

enot [183]

Answer:

D. Collinear

Step-by-step explanation:

Three points lying on a line are collinear because they share the same line.

the rest of the options can be ruled out because the points can not be congruent due to lack of distance information and the same goes for midpoint and equal.
