Answer:
x=13°
Step-by-step explanation:
If BE is an angle bisector, then it divides the angle into two equal angles. This means that
∠ABE=∠EBC
Since ∠ABE=2x+20 and ∠EBC=4x-6, we have
2x+20=4x-6
2x-4x=-6-20
-2x=-26
2x=26
x=13°
Answer:
C . Sample : 6 boy and 7 girls
Step-by-step explanation:
Data :
Boys = 150
Girls = 175
So ratio between boys and girls
175/150 = 1.67
So when boy is 6
6 ×1.667 = 7
Answer:
(-3, infinity)
Step-by-step explanation:
Range the y values, meaning up and down. The highest point is neverending therefore, infinity. The lowest point is -3.
I'm pretty sure this is correct.
Answer:
The root is x = -2
Step-by-step explanation:
1. Add 4 on both sides.
x^2 + 4r + 4 = 0
2. What two numbers, if added together and multiplied together, give 4?
2 and 2.
3. Factor
(x+2)(x+2)=0
4. Solve
x = -2 (There is only one root for this quadratic equation.)
