Answer: y = x + 1

Step-by-step explanation:

y = 1x + c

-7 = 1(-8) + c

-7 = -8 + c

-7 + 8 = c

1 = c

y = 1x + 1 or

y = x + 1

Write the first five terms of the sequence defined by the explicit formula

denis-greek [22]

<u>Answer:</u>

The correct answer option is: 19, 13, 3, -11, -29.

<u>Step-by-step explanation:</u>

We are given the following explicit formula for an arithmetic sequence:

$a_n=21-2n^2$

So to find the first five terms of this sequence, we will substitute the values of $n$ (num here in the given formula:

$a_1=21-2(1)^2\\\\a_1=19$

$a_2=21-2(2)^2\\\\a_2=13$

$a_3=21-2(3)^2\\\\a_3=3$

$a_4=21-2(4)^2\\\\a_4=-11$

$a_5=21-2(5)^2\\\\a_5=-29$

Therefore, the first five terms of the sequence defined by the explicit formula $a_n=21-2n^2$ are 19, 13, 3, -11, -29.

Please help ill give brainiest answer!

1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.

$58 + 58 + x = 180$

$116 + x = 180$

$x = 64$

1. m{t}°=64 m{I}°=58

2. This one is easy because algebra is the key.

$100 - x + 30 + 4x + 7x = 180$

Add like-terms.

$130 +10x = 180$

$10x = 50$

$\frac{50}{10} = x = 5$

x=5

The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
