1 answer:

7 0

Answer:

${ \tt{12 {y}^{2} + 12y - 3 {y}^{3} = 124 - (y + 5)}} \\ 3 {y}^{3} - 12 {y}^{2} - 12y = - 124 + (y + 5) \\ {3y}^{3} - 12 {y}^{2} - 12y = - 124 + y + 5 \\ { \tt{3 {y}^{3} - {12y}^{2} - 11y + 119 = 0 }}$

Answer:

an = -6n + 5.

Step-by-step explanation:

This is an arithmetic sequence with first term a1 = -1 and common difference d = -6

an = a1 + d(n-1)

an = -1 + -6(n - 1)

an = -1 -6n + 6

an = -6n + 5.

A right triangle has legs that measure 7 cm and 6 cm. What is the length of the hypotenuse in meters?

Answer:

$\sqrt{85} or 9.22$

Step-by-step explanation:

You need to remember the following equation:

$a^{2} + b^{2} = c^{2}$

Where a and b is the lengths of the two sides and c is the hypotenuse.

So simply plug these values into this:

$6^{2} + 7^{2} = h^{2}$

36 + 49 = h^2

36 + 49 = 85

So the hypotenuse is the square root of 85:

$\sqrt{85} = 9.22$

58 = 7/4x well, basically I am really bad with fractions, and I'm supposed to do this on a computer, I don't have a calculator I

KiRa [710]

58=7/4x
Multiply both sides by 4 so the fraction cancels out:
232=7x
Divide both sides by 7:
x=33.14 (rounded)

Hope this helps :)
