Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smalle

Rus_ich [418]

Answer:

y = negative four-thirds x + StartFraction 31 Over 3 EndFraction

y = 2 x + 7

Step-by-step explanation:

Let x represent the smaller number and y represent the larger number.

Four times a number added to 3 times a larger number is 31.

It is translated as:

4x + 3y = 31

Then, solving for y:

4x + 3y=31 ⇒ 3y= -4x+31 ⇒ y= (-4x+31)/3 = - 4/3x + 31/3

⇒ y= - 4/3x + 31/3

Correct answer choice for this equation:

y = negative four-thirds x + StartFraction 31 Over 3 EndFraction

Seven subtracted from the larger number is equal to twice the smaller number.

It is translated as:

y-7= 2x

Then, solving for y:

y-7= 2x ⇒ y= 2x+ 7

Correct answer choice for this equation:

y = 2 x + 7

How was this answered? i don't know how, pls. help

ratelena [41]

Answer:

see explanation

Step-by-step explanation:

Using $\sqrt{-1}$ = i, then i² = ( $\sqrt{-1}$ )² = - 1

and i³ = i² × i = - 1 × i = - i

also

$i^{4}$ = i² × i² = - 1 × - 1 = 1

We can surmise that i raised to any multiple of 4 will equal 1

Given

$i^{35}$ ( note 35 = 32 + 3 and 32 is a multiple of 4 ), thus

= $i^{32+3}$

= 1 × i³ = - i
