Answer:
f(-1) = 7
Step-by-step explanation:
Put -1 where x is and do the arithmetic.
f(-1) = 2(-1) +9 = 7
ASA because when you look at the corners it marks the angles and then a line for the side in between it. That’s how I always looked at it
Answer:
The proof is explained step-wise below :
Step-by-step explanation:
Given : ∠C and ∠R are supplementary. Also, ∠C and ∠R are congruent
To Prove : ∠C and ∠R are right angles ⇒ ∠C = ∠R = 90°
Proof : Given ∠C and ∠R are congruent and the congruent angles are equal in measure.
⇒ m∠C = m∠R .........(1)
Now, ∠C and ∠R are supplementary
⇒ ∠C + ∠R = 180°
⇒ ∠C + ∠C = 180° ( From equation (1) )
⇒ 2∠C = 180°
⇒ ∠C = 90°
Hence, ∠C = ∠R = 90°
⇒ ∠C and ∠R both are right angles.
Hence Proved.
Answer:
25%
Step-by-step explanation:
The answer would be 25% because to get your answer you have to
first subtract the original amount by the newest amount which in this case is
96-72=?
After you have subtracted this you will get you answer of 24
96-72=24
Ans than what you do is take the number of how many people left and put it on top of the original amount like this
24/96 so in other words dividing
Than you will get your answer of 25%
