Answer:

<em>3</em>

Step-by-step explanation:

<em>Given </em><em> </em>

<em>f(</em><em>x</em><em>)</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>3x </em><em>+</em><em> </em><em>5</em><em> </em>

<em>f(</em><em>x</em><em>)</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>4</em><em> </em>

<em>-</em><em>3</em><em>x</em><em> </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>4</em><em> </em>

<em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>-</em><em> </em><em>4</em><em> </em><em>-</em><em> </em><em>5</em><em> </em>

<em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>-</em><em> </em><em>9</em><em> </em>

<em>x </em><em>=</em><em> </em><em>3</em><em> </em>

Answer and Step-by-step explanation:

8. HL theorem - Has a right angle and the legs.

9. ASA - Angle A is congruent to angle B because of interior angles theorem, side AM is congruent to side MB because of midpoint theorem, angle AMC is congruent to angle BMD because of vertical angles theorem.

10. SSS - The two sides are congruent, and the hypotenuse is shared, making it congruent.

11. SAS - The two sides are congruent, and the angle between the congruent sides are congruent.

Why is a sequence a function and how can you write a rule for a sequence?
statuscvo [17]
Certain sequences (not all) can be defined (expressed) in a "recursive" form. <span>
In a <span>recursive formula, </span>each term is defined as a function of its preceding term(s). <span>
[Each term is found by doing something to the term(s) immediately in front of that term.] </span></span>
A recursive formula designates the starting term,<span><span> a</span>1</span>, and the nth term of the sequence, <span>an</span> , as an expression containing the previous term (the term before it), <span>an-1</span>. 

<span><span>The process of </span>recursion<span> can be thought of as climbing a ladder.
To get to the third rung, you must step on the second rung. Each rung on the ladder depends upon stepping on the rung below it.</span><span>You start on the first rung of the ladder. </span><span>a1</span>
<span>From the first rung, you move to the second rung. </span><span>a<span>2
</span>    a2</span> = <span>a1 + "step up"
</span><span>From the second rung, you move to the third rung. </span><span>a3</span>
<span>    a3 = a2 + "step up"</span>
<span><span>If you are on the<span> n</span>th rung, you must have stepped on the n-1st rung.</span>    <span>an = a<span>n-1</span> + "step up"</span></span></span><span><span>Notation:<span> Recursive forms work with the term(s) immediately in front of the term being examined. The table at the right shows that there are many options as to how this relationship may be expressed in </span>notations.<span>A recursive formula is written with two parts: a statement of the </span>first term<span> along with a statement of the </span>formula relating successive terms.The statements below are all naming the same sequence:</span><span><span>Given TermTerm in front
of Given Term</span><span>a4a3</span><span>ana<span>n-1</span></span><span>a<span>n+1</span><span>an</span></span><span><span>a<span>n+4</span></span><span>a<span>n+3</span></span></span><span><span><span>f </span>(6)</span><span><span>f </span>(5)</span></span><span><span><span>f </span>(n)</span><span><span>f </span>(n-1)</span></span><span><span><span>f </span>(n+1)</span><span><span>f </span>(n)</span></span></span></span>


<span><span> Sequence: {10, 15, 20, 25, 30, 35, ...}. </span>Find a recursive formula.
This example is an arithmetic sequence </span>(the same number, 5, is added to each term to get to the next term).
