Answer:
X= -3
Y= 7
a= -6
b = -28
C = 9
D= -7
Step-by-step explanation:
2x – 4y = -34
-3x - y = 2
2x – 4y = -34
-12x - 4y = 8
-14x = 42
X= 42/-14
X= -3
-3x - y = 2
-3(-3) -y = 2
9-y = 2
9-2= y
Y= 7
a = 2x
a= 2*-3
a= -6
b = -4y
b = -4*7
b = -28
C= -3x
C= -3*-3
C = 9
D= -y
D= -7
Answer: x= (2/3,0) y=(0,2)
X=(4,0) y=(0,8)
X=(-3,0) y=(0,-3)

Answer: 0.11
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
So we can think of 11% as the ratio 11 to 100 or 11 divided by 100.
Dividing by 100 moves the decimal point 2 places to the left so 11 divided by 100 would move the decimal point 2 places to the left which would give us <em>.</em>11 or 0<em>.</em>11.
So 11% can be written as the decimal 0<em>.</em>11.

Answer:
$31.104
Step-by-step explanation:
Given :
Regular price = $36
Discount on sale = 20%
Discounted price = (100-20)%*36=0.8*36 = $28.8
Sales tax rate = 8% ;
Tax on sale = 8% * $28.8 = 2.304
Final amount that will have to be paid :
Discounted price + tax on sale
$28.8 + $2.304
= $31.104
