Because there is a +e and a -e in the two equations we can simply add them together to solve for d...
2d+e+d-e=8+4 combine like terms
3d=12 divide by 3
d=4, now use this d in either original equation to solve for e...<span>d–e=4 so
4-e=4 subtract 4
-e=0
e=0
So the solution, where the lines intersect graphically, is the point (4, 0)</span>
As AB is a diameter, then m∠CBA=180^{0}-75^{0}=105^{0}.
∠CBA is a central angle, so its measure multiplied by radius is the length of arc AC.
Note that
and
. Then
and length of the arc is
.The correct answer is 22 in.
Answer:6y-7.5
Step-by-step explanation: open the bracket first. Then you will have this
3y+3y-7.5
Final and =6y-7.5
Answer: The system will succeed when the first alarm rings or when the first one fails, but the second one rings. The probability of this is 0.98
The probability of system failure is 1-(probability of success)= 1-0.98= 0.02
Step-by-step explanation:
$1200 multiplied by .10=120, So 1200 minus 120 will give you your answer
