Answer:
-7
Step-by-step explanation:
use X to represent the unknown number
(x-16) -6=-138
-138/6= -23
(x-16)=-23
add 16 to both sides
x= -7
Julio's number is -7
you can also plug it back into the formula to prove it is right
Answer:
Reflection about y=2
Step-by-step explanation:
Triangle A should be reflected about y=2 to map it onto Triangle B.
Answer: it should be 10!
Step-by-step explanation:
the area of a triange is a=bh/2, so if you plug in your base and height, you get ten!
Mean=0.48
standard deviation=0.01
thus using the z-score:
P(x>0.5) we shall have the following:
z=(0.5-0.48)/0.01=2
thus
P(x>0.5)
=1-P(x<0.5)
=1-P(z<2)
=1-0.9772
=0.0228
<span>Since it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem. For the same reason, if m∠B < m∠C, then AC < AB. This is a contradiction to what is given. Therefore, it can be concluded that
Answer: Angle (B) is Congruent to Angle (C)
