Answer:
=============================
The horizontal line has same y- coordinate for each x- coordinate, and is parallel to the x-axis so it is:
The vertical line has same x- coordinate for each y- coordinate, and is parallel to the y-axis so it is:
<em>Refer to graphs.</em>
It's the parallelogram. Therefore
ML = JK, JM = KL, m∠L = m∠J, m∠M = m∠K and m∠M + m∠L = 180°.
ML = 21 → JK = 21
JM = 29 → KL = 29
m∠L = 127° → m∠J = 127°
m∠M + m∠L = 180° → m∠M + 127° = 180° → m∠M = 53°
m∠M = 53° → m∠K = 53°
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)
