{x + 8y = -16<br> {x-3y = -5

Anna007 [38]

Answer: y= -1 and x=-8

x+8y=-16

x=-8y-16

so x-3y=-5

-8-16-3y=-5

-11y-16=-5

-11y=-5+16

-11y=11

y=-1

x-3y=-5

x+3=-5

x=-8

Solve the system algebraically.<br> y = – 4x + 6<br> y = – 4x + 5

Nana76 [90]

Answer:

We conclude that -1 = 0 is false, therefore the system of equations has no solution.

Step-by-step explanation:

Given the system of equations

y = – 4x + 6

y = – 4x + 5

solving the system of the equations

$\begin{bmatrix}y=-4x+6\\ y=-4x+5\end{bmatrix}$

Substitute y = -4x+5

$\begin{bmatrix}-4x+5=-4x+6\end{bmatrix}$

Refine – 4x + 5 = – 4x + 6

-1 = 0

FALSE!

NO SOLUTION!

We conclude that -1 = 0 is false, therefore the system of equations has no solution.

Natalka [10]

R = 6 in;
60° = 1/6 · 360°
The area of the slice of pie:
A = 1/6 · r² · π
A = 1/6 · 6² · 3.14 = 18.84 in²
