Step-by-step explanation:

Case 1 :

$3x + 2y = 6 \\ 4x + y = 2 \\ 3x = 6 - 2y \\ x = \frac{6 - 2y}{3} = \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) + y = 2 \\ 8 - \frac{8y}{3} + y = 2 \\ - 1.67y = - 6 \\$

$y = 3.59 \\ x = 2 - \frac{2y}{3} \\x = 2 - \frac{2 \times 3.59}{3} \\ \\ x = - 0.39$

Case 2 :

$3x + 2y = 6 \\ 4x - y = 2 \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) - y = 2 \\ 8 - \frac{8y}{3} - y = 2 \\ - 3.67y= - 6 \\ y = 1.63$

$x = 2 - \frac{2y}{3} \\ x = 2 - \frac{2 \times 1.63}{3} \\ x = 2 - 1.087 \\ x = 0.913$

If ABC company make 95 million a year how much money would it make in 9 days

faust18 [17]

1. Divide 95 million by the amount of days in a year

95 million divided by 365 = $260273.97

$260273.97 is made in a day.

Multiply it by 9.

So, 260273.97 x 9 = $2342465.75

$2342465.75 is made in 9 days.

Answer:

First angle: 27

Second angle: 135

Third angle: 18

Draw a triangle with one obtuse angle and 2 acute angles.

Step-by-step explanation:

Determine the variables:

first angle: f

second angle: s

third angle: t

Write an equation for the second angle:

s=5f

Write an equation for the third angle:

t=2/3f

Write an equation for the total angle measurements:

s+t+f=180

Substitute them and solve

5f+2/3f+f=180

f=27

5(27)=135=s

2/3(27)=18=t

First angle: 27

Second angle: 135

Third angle: 18

Find the zeros of the function. f(x) = 4x3 - 12x2 - 40x

mote1985 [20]

First take out the GCF which is 4x

4x (x^2 - 3x - 10) = 0

4x(x - 5)(x + 2) = 0

4x = 0 so x = 0

x - 5 = 0 so x = 5

x+2 = 0 so x = -2

zeros are -2, 0 and 5
