Answer:
y = -x/4 + 7/2
Step-by-step explanation:
Find the slope
( -2 , 4) ( 6 , 2)
m = (y2 - y1)/(x2 - x1)
x1 = -2
y1 = 4
x2 = 6
y2 = 2
m = ( 2 - 4)/( 6 -(-2)
m = ( 2 -4)/(6 +2)
= -2/8
= -1/4
Using point slope form equation
y - y1 = m( x - x1)
Using the second point
( 6 , 2)
x1= 6
y1=2
m = -1/4
y - 2 = -1/4(x - 6)
y - 2 = -(x - 6)/4
Open the bracket with -
y - 2 = (-x + 6)/4
y = ( -x + 6)/4 + 2
LCM = 4
y =( -x + 6 + 8)/4
y = (-x + 14)/4
Rearrange using slope intercept form
y = mx + c.
y = -x/4 + 14/4
We can break 14/4 by dividing by 2
y = -x/4 + 7/2

Answer:
А.(x-6)(x2 + 6x + 36)
Step-by-step explanation:
Remember this formula for factorizing difference of 2 cubes:
a
3
−
b
3
=
(
a
−
b
)
(
a

+
a
b
+
b

)
In

,
a

=
216
a
=
3
√
x
3
=

Substitute
a

,
b
=

into the formula of
(
a

)
(
a

+
a
b

)
(
x

)
(
x

)
=
(
x

Well, the Pythagorean theorem is helpful.
Does 7^2+19^2=25^2?
no it desn't, so no it is not a right triangle
Triangle DEF is scalene
