Find the fourth term of the sequence given by the rule tn= -2(2)^n-1 A) 32 B) -32 C)-1 6 D) 16
BartSMP [9]
<h2>Answer: C)-16</h2>

Step-by-step explanation:

We have a sequence with the following rule:

t_{(n)}=-2(2)^{n-1}

This gives us the n term of the sequence. Now, if we want to find the fourth term, we have to substitute n by 4:

t_{(4)}=-2(2)^{4-1}

t_{(4)}=-2(2)^{3}

t_{(4)}=-2(8)

Finally:

t_{(4)}=-16 This is the fourth term of the sequence

Substitue the expression 5-3x into the second equation
Rina8888 [55]

Answer:

<h2><u>X= 1</u></h2>

Step-by-step explanation:

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

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

you substitute for y since you know what y equals.

so, it will then be

5x -4(5 -3x) = -3

you then multiply -4 by everything in the parenthesis

so then it will be

5x - 20 + 12x = -3

Then combine like terms

5x + 12x = 17x

then the new equation is

17x -20 = -3

the next step is to and 20 to both sides since it is negative you do the opposite.

17x - 20 = -3

<u>      + 20     +20</u>

17x = 17 divide 17 by both sides sice 17 is being multiplied by x you do the opposite and divide and you get 1.

<h2><u>so, X = 1</u></h2>

What is the measure of the missing angle?​
goblinko [34]

Answer:

<u>The missing angle measures also 110°</u>

Step-by-step explanation:

Let's recall that If the transversal cuts across parallel lines (apparently, this particular case) then those alternate exterior angles have the same measure (.∠ 110° and ∠?) So in the figure given, the two alternate exterior angles measure the same.

<u>The missing angle measures also 110°</u>

Ratling [72]

Answer:

(2, 11)

Step-by-step explanation:

So, we have to make them equal to each other.

5 = 2x + 16

Subtract 5 from both sides

y = 2x + 11
