The answer to the first question of the attached document is option 1. We obtain the answer subtracting the term n from the series with the term n-1.For example:
 -3 - (- 5) = 2
 -1 - (- 3) = 2
  1 - (- 1) = 2
 So you can see that the common difference is the 2.

 The answer to the second question is option 3:
 y = | x + 7 |
 We can confirm it by substituting values in the equation.
 For example:
 if we do y = 0 then x = -7
 if we do x = 0 then y = 7.
 As corresponds in the graph shown.
 Remember also that as a general rule yes to the equationy = | x | whose vertex is in the point (0,0) we add a positive real number "a" of form y = | x + a | then the graph of y = | x | will move "to" units in the negative direction of x.

 The answer to the third question is option 4.
 The quotient of x and "and" is constant.
 k = y / x
 Rewriting:
 y = kx
 You can see that it corresponds to the equation of a line that passes through the origin, this means that and is proportional to x and both vary directly

How do you find x? and how do you round to the nearest tenth?
expeople1 [14]

Hey there!

In order to solve this problem, we can use the Pythagorean Theorem, which is c^2 = a^2 + b^2. Since the Pythagorean Theorem would find only half of the length of x, we'll need to double it in the end.

First, let's plug in what we know to the Pythagorean Theorem: 2.1^2 = 1.4^2 + b^2

Next, we'll simplify to that b^2 is by itself:

b^2 = 2.45

Then, we'll find the square root of 2.45, multiply that by 2 and round to the nearest tenth:

2(\sqrt{2.45} ) = 3.1

Therefore, x = 3.1 ft.


How to round to the nearest tenth:

In a decimal, the tenth is the first number after the decimal point. To round to the tenth, if the number in the hundredth place is less than 5, you keep the number as it is, but if the number in the hundredth place is more than 5, you increase the number in the tenth place by 1.


Hope this helps!! :)

Write (5,0) with a slope of 2 in slope-intercept form
tia_tia [17]
Y = mx + c
y = 2x + c
When x = 5 and y = 0,
0 = 2(5) + c
c = -10

y = 2x - 10
