Answer:
C
Step-by-step explanation:
Angle in a triangle add up to 180
since this is an isosceles triangle two angles are the same
180-(47+47)=86
Opposite angles are equal
Angles around a point add up to 360
360-(86+86)=188
188/2=94
94 degrees
C
Answer:
the slope is flatter
the line is shifted 7 down
Step-by-step explanation:
First you have to leave your y alone so you want to move the -1. Since you are moving it to the other side it will now become a +1. It will be +1-9 which will equal to -8. Now you have -8=-2y. You want to permanently leave the y alone so now you divide by 2. (-8/-2=-2y/-2) It should be 4=y. That means that 4 is your answer. Remember to make your answer a positive number because it is a negative divided by a negative!
Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.
