Answer:
The answer is B.thus 7.4*10^9
Step-by-step explanation:
This is because,in scientific notation, we deal with numbers which are in the standard form
And <em>from</em><em> </em><em>alt</em><em> </em><em>A-D</em><em> </em><em>,</em><em> only</em><em> </em><em>the</em><em> </em><em>alt</em><em> </em><em>B</em><em> </em><em>is</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>stan</em><em>dard</em><em> </em><em>form</em><em>.</em><em> </em><em>the</em><em> </em><em>res</em><em>t</em><em> </em><em>are</em><em> </em><em>no</em><em>t</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>stan</em><em>dard</em><em> </em><em>form</em><em> </em><em>hen</em><em>ce</em><em> </em><em>cann</em><em>ot</em><em> </em><em>be</em><em> </em><em>consi</em><em>dered</em><em> </em><em>them</em><em> </em><em>as</em><em> </em><em>wri</em><em>tten</em><em> </em><em>In</em><em> </em><em>sci</em><em>entific</em><em> </em><em>nota</em><em>tion</em><em>.</em>
Answer:
sometimes
Step-by-step explanation:
always and never would not make sense since saying it is possible that it is true or false.
1/5 or -1/9 would both be correct
Answer:
x = 36
Step-by-step explanation:
The angles 3x - y and 2x + y form a straight angle and are supplementary, so
3x - y + 2x + y = 180
5x = 180 ( divide both sides by 5 )
x = 36
-----------------------------------------------
5y and 3x - y are vertical angles and congruent, hence
5y = 3x - y ( add y to both sides )
6y = 3x ← substitute x = 36
6y = 3 × 36 = 108 ( divide both sides by 6 )
y = 18
Answer:
there are no signs between the x and y and constant
it could be
2x+5y=15
2x+5y=-15
-2x+5y=15
2x-5y=15
for ax+by=c, the equation of a line paralell to that is
ax+by=d where a=a, b=b, and c and d are constants
(for this answer, I'm going to use 2x+5y=15)
given 2x+5y=15, the equation of a line paralell to that is 2x+5y=d
to find d, subsitute the point (4,-2), basically put 4 in for x and -2 for y to get the constant
2x+5y=d
2(4)+5(-2)=d
8-10=d
-2=d
the eqaution is 2x+5y=-2 (Only if the original equation is 2x+5y=-15
