After solving the linear system, value of x=3 and value of y=2

Step-by-step explanation:

We need to find the solution to the linear system $x=-6y+15\,\,and\,\, -2y+5x =11$

$x=-6y+15\,\,\,\,(1)\\-2y+5x =11\,\,\,\,(1)$

Putting value of equation (1) x=-6y+15 in equation(2)

$-2y+5x =11\\-2y+5(-6y+15)=11\\-2y-30y+75=11\\-32y=11-75\\-32y=-64\\y=\frac{-64}{-32}\\y=2$

value of y=2

Now putting the value of y in equation (1)

$x=-6y+15\\x=-6(2)+15\\x=-12+15\\x=3$

value of x = 3

After solving the linear system, value of x=3 and value of y=2

Answer:

Step-by-step explanation:

h = √6 units

b = √9 units

A = b*h/2 = √6·√9 /2 = √(6·9)/2 = √(2·3·3·3)/2 = 3√3 /2 units ²≈ 2.6 units²

Jones Co. pays its employees on a graduated commission scale: 2% on first $30,000; 3% on sales from $30,000 to $60,000; and 5% o

Gnesinka [82]

We need to separate his total earnings out into the different categories:

Category 1 (2%): 30,000
Category 2 (3%): 60,000-30,000 = 30,000
Category 3 (5%): 92,000-60,000 = 32,000

To calculate a percentage we multiply by that percentage divided by 100.
Now we can work out the commissions:
1) 30,000*0.02 = $600
2) 30,000*0.03 = $900
3) 32,000*0.05 = $1600

Adding these together, we get $3100
