0.12 because all the other ones have .00's behind them and .0= nothing so 12.00= 12 12.0= 12 and 0.12=0.12.
Hello,
Perpendicular sloop m is : 4*m=-1==>m=-1/4
Equation 's line is y-3=-1/4(x-8) or y=-x/4+5
The cost of each order of fried crab claw is $4.5 and cost of each cup of gumbo is $3.5
Step-by-step explanation:
Let,
Cost of each fried crab claw = x
Cost of each gumbo = y
According to given statement;
4x+4y=32 Eqn 1
2x+y = 12.5 Eqn 2
Multiplying Eqn 2 by 2
Subtracting Eqn 3 from Eqn 1
Dividing both sides by 2
Putting y=3.5 in Eqn 2
Dividing both sides by 2
The cost of each order of fried crab claw is $4.5 and cost of each cup of gumbo is $3.5

Let's first write each step of the procedure:
Step 1:
group the x terms together and the terms and together, and move the constant term to the other side of the equation:
x² + 12x + y² + 2y = 1
Step 2:
determine (b ÷ 2) 2 for the x and y terms.
(12 ÷ 2) 2 = 36
and
(2 ÷ 2) 2 = 1
Step 3:
add the values to both sides of the equation.
x2 + 12x + 36 + y2 + 2y + 1 = 1 + 36 + 1
Step 4:
write each trinomial to binomial squared, and simplify the right side.
(x + 6) 2 + (y + 1) 2 = 38
Answer:
the last step is:
(x + 6) 2 + (y + 1) 2 = 38
Answer:
x= -2, y = -3
Step-by-step explanation:
1. substitute x = 4+2y in the first equation:
simplify it :
2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->
3. solve for y: 5y = -15 --> y = -15/5 --> y= -3
4. solve for x: x = 4 + 2y
x = 4 + 2(-3)
x = 4 + (-6)
x = -2
