x=√11
Answer: I think it’s D
Step-by-step explanation:
it’s because 8^2 + 13^2 equals 233 and when square rooted equals 15.26 not 20 so no.
Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the carbon dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.
I believe the answer would be C. u subtract the 5 from both sides and divide by the -4 and flip the inequality. it has to be greater than than 13/4.
Answer:-10
Step-by-step explanation: The slope-intercept form is
y
=
m
x
+
b
y
=
m
x
+
b
, where
m
m
is the slope and
b
b
is the y-intercept.
y
=
m
x
+
b
y
=
m
x
+
b
Find the values of
m
m
and
b
b
using the form
y
=
m
x
+
b
y
=
m
x
+
b
.
m
=
−
6
m
=

6
b
=
−
10
b
=

10
The slope of the line is the value of
m
m
, and the y-intercept is the value of
b
b
.
Slope:
