I need to know how to write this expression forty-three less than twice a number, n

Sindrei [870]

N= a number
2n= twice a number

If it's 43 less, then it would be 2n-43.

2n-43 is the answer.

Hope this helps! :)

Answer:

The equation will be " $y=-2.8 x+75$ ".

Step-by-step explanation:

The given values are:

Started with,

= 75 gallons

After 15 hrs,

Tank has,

= 33 gallons

Now,

The slope will be:

= $\frac{33-75}{15}$

= $\frac{-42}{15}$

= $-2.8$

Thus,

The equation is " $y=-2.5x+75$ ".

(6+√-64)(3-√-16) Multiply. This is urgent, please explain this to me!

romanna [79]

Answer:

Step-by-step explanation:

$\sqrt{-64}$ and $\sqrt{-16}$ can be expressed in complex form, with $\sqrt{-1}$ = i

$\sqrt{-64}$ = $\sqrt{64(-1)}$ = $\sqrt{64}$ × $\sqrt{-1}$ = 8i

$\sqrt{-16}$ = $\sqrt{16(-1)}$ = $\sqrt{16}$ × $\sqrt{-1}$ = 4i

the factors can then be expressed as

(6 + 8i)(3 - 4i) ← expand using FOIL

= 18 - 24i + 24i - 32i² [ i² = ( $\sqrt{-1}$ )² = - 1 ]

= 18 - 24i + 24i + 32 ← collect like terms

= 18 + 32 + 0

= 50
