Algebra 1 Writing Standard 1: Write arguments to support claims in an analysis of substantive topics or texts, using valid reasoning and relevant and sufficient evidence. Problem: f(x)=2(+ 5) - 4
Evaluate: Prove: f(-2)
When Kylie completed this problem, he did the following work: f(-2) = 2 (-22 + 5) - 4 f(-2) = 2(-4+5) - 4 f(-2) = 2(1) -4 f (-2) = 2 - 4 f(-2) = -2 Claim: Is Kylie correct? Yes or No Reasoning: Explain your answer by justifying how you determined if she was correct or not.​

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

the answer is b.
