A
Step-by-step explanation:
idk i cant see anything
We have to determine if the sets of quadratics are equivalent:
A ) x² - 10 x - 14 = 0 and ( 2 x - 10 )² = 156
( 2 x - 10 )² - 156 = 0
4 x² - 40 x + 100 - 156 = 0
4 x² - 40 x - 56 = 0 / : 4
x² - 10 x - 14 = 0 T ( True )
B ) ( x - 10 )² = 68 and x² - 20 x = - 32
( x - 10 )² = 68
x² - 20 x + 100 = 68
x² - 20 x = 68 - 100
x² - 20 x = - 32 T ( True )
C ) x² - 6 x = 247 and ( x - 3 )² = 256
( x - 3 )² = 256
x² - 6 x + 9 = 256
x² - 6 x = 247 T ( True )
D ) ( x + 5 )² = 65 and x² = 90 - 10 x
( x + 5 )² = 65
x² + 10 x + 25 = 65
x² = 65 - 25 - 10 x
x² = 40 - 10 x F ( False )
Answer:
$70
Step-by-step explanation:
1 - ⅙ - ¼ = (12 - 2 - 3)/12 = 7/12
7/12 × 480 = 280
280/4 = 70
Answer:
Step-by-step explanation:
The slope-intercept form is
y
=
m
x
+
b
, where
m
is the slope and
b
is the y-intercept.
y
=
m
x
+
b
Find the values of
m
and
b
using the form
y
=
m
x
+
b
.
m
=
5
b
=
0
The slope of the line is the value of
m
, and the y-intercept is the value of
b
.
Slope:
5
y-intercept:
0
with this context we can only assume it would be z-5
