What is the solution to the equation represented by the model below?

Verizon [17]

Left side:

x+x+x+1+1+1+1+1+1+1+1 = 3x + 8

Right side:

x+x+x+x++1+1+1+1+1+1

Left side = Right side to solve x

3x + 8 = 4x + 6

Subtract 4x from both sides

3x + 8 - 4x = 4x + 6 - 4x

Simplify

-x + 8 = 6

Subtract 8 from both sides

-x + 8 - 8 = 6 - 8

Simplify

-x = -2

Multiply both sides by (-1)

-x * (-1) = -2 * (-1)

Simplify

x = 2

Answer

C. x = 2

Tamiku [17]

Answer:

Step-by-step explanation:

$2(x + y) + (2x - 2y) \\ = 2x + 2y + 2x - 2y \\ = 2x + 2x + 2y - 2y \\ = 4x + 0 \\ = 4x$

Find the value of i77.<br> A) 1 <br> B) i <br> C) −1 <br> D) −i

Colt1911 [192]

assuming you mean $i^{77}$ where $i=\sqrt{-1}$

ok, notice a pattern in the exponent

$i^1=i=\sqrt{-1}$

$i^2=-1$

$i^3=-\sqrt{-1}=-i$

$i^4=1$

$i^5=i=\sqrt{-1}$

hum, so it goes 1,2,3,4, then repeats

ok, so every 4, the cycle repeats

how far up is 77 from a multipule of 4?

4*19=76

76 is 1 away from 77

so $i^{77}=(i^{76})(i^1)=$

$(i^4)^{19}(i)=(1)^{19}i=i$

the answer is B
