Answer:

You end up at point (7,5).

Step-by-step explanation:

Starting point:

The coordinates of the starting point are: x = 4, y = 6.

(4,6).

Move 3 units right:

Moving 3 units right is adding 3 to the x-coordinate. So

x = 4 + 3 = 7

(7,6).

Move 1 unit down:

Moving 1 unit down is subtracting 2 from the y-coordinate. So

y = 6 - 1 = 5.

You end up at point (7,5).

Find an explicit formula for the following sequence, an which starts with a1=−1. −1,1/2,−1/3,1/4,−1/5,…

Dimas [21]

Answer:

The sequence can be represented by the formula of its nth term:

$a_n=\frac{(-1)^n}{n}$

Step-by-step explanation:

Notice that we are in the presence of an alternate sequence (the values alternate from negative to positive. Therefore we need to take into account that there should be a factor "-1" raised to the "n" value for the sequence. Also, given that the sequence looks in absolute value like the harmonic sequence, we conclude upon the following general form for the "nth" term of the sequence:

$a_n=\frac{(-1)^n}{n}$

Simplify 24-(6+9)÷3+42÷2

OLEGan [10]

Answer:

The answer when solving this problem would be 40, but to simplify I am not exactly sure. I would defenitely use photomath if you could. Math is not my strong suit so this answer could very well be all sorts of wrong. Photomath helps to explain how to do the problem thoroughly. When typing the answer into this app be sure to include simplify.

Step-by-step explanation:

PEMDAS. (solve)

24-(6+9)/3+42/2

24-(15)/3+42/2

24-(5)+42/2

24-(5)+21

19+21

Factorise (x+1)^2 + 4(x+1)

mafiozo [28]

Answer:

(x + 1)(x + 5)

Step-by-step explanation:

Given

(x + 1)² + 4(x + 1) ← factor out (x + 1) from each term

= (x + 1)(x + 1 + 4)

= (x + 1)x + 5)
