HELP Solve the following systems using the elimination method. 5x+2y = -16 4x-2y = 16

velikii [3]

Answer:

x= 0 , y= -8

Step-by-step explanation:

Add the 2 equations together, you would get:

9x = 0

Divide both sides by 9:

x = 0/9

x=0

Substitute the value of x in one of the equations to get the value of y, I picked the first one (5x+2y = -16)

5(0) +2y = -16

0+2y = -16

2y = -16

Divide both sides by 2:

y = -8

Find the area of the circle with the following dimension diameter = 4 cm

Elis [28]

Answer:

$A = 12.56 cm^{2}$

Step-by-step explanation:

When you want to find area out of diameter. These are the steps you follow:

1. Convert diameter to radius

2. Solve for area

First step:

When you need to convert diameter to radius, you just need to divide by 2

$d = 4cm / 2cm$

$==> 2cm$

Second step:

Use formula $A = \pi * r^{2}$

A = $\pi * 2cm^2$

A = $\pi * 4cm$

A= $12.56cm$
