Answer:
Step-by-step explanation:
You will use the FOIL method, which is very similar to the distributive property.
In order to do multiply correctly, multiply the y by 3x, 5y, and -2. You should get:
Then multiply the -4 by 3x, 5y, and -2 where you should get:
By using the foil method, you got rid of the parentheses. Now you can simply combine like terms and get your final answer:
I hope this helps you!
Angle DFB = (1/2)*[(arc CE)+(arc BD)]
Angle DFB = (1/2)*(84+38)
Angle DFB = (1/2)*122
Angle DFB = 61
(Angle DFB) + (angle DFE) = 180
angle DFE = 180 - (Angle DFB)
angle DFE = 180 - 61
angle DFE = 119 degrees
---------------------------------------
Final Answer is choice D) 119 degrees
The absolute value sign makes it so that k+7 could be either -3 or +3 and the result would still be 3. This means there are two possible answers for k. The one that makes k+7=-3 and the one that makes k+7=+3. Just solve these two equations:
k+7=-3
k=-3-7
k=-10
k+7=3
k=3-7
k=-4
So the possible answers are -4 and -10. B is the correct choice.

Answer:
-3x > -30
Step-by-step explanation:
The graph can be described simply as ...
x < 10
If we multiply the equation by -3, we have to reverse the inequality symbol. Then we get ...
-3x > -30
