y= 3x –4
3x + y = –4
3x + (3x –4) = –4
3x+3x – 4 = – 4
6x = – 4 +4
6x=0 —> x= 0/6 —> x=0
x = 0y = 3x – 4 —> y = 3(0) – 4 = – 4
y = – 4So; (x , y) —> (0 , – 4 )I hope I helped you^_^
Answer:
(0,-4)
Step-by-step explanation:
3x + y = -4
3x + (3x - 4) = -4
3x + 3x - 4 = -4
6x = 0
x = 0
y = 3(0) - 4
y = -4

y-3 = 2(x+1)
fiind the missing value ?
Step by step process:
Let's solve for x.
y−3=2(x+1)
Step 1: Flip the equation.
2x+2=y−3
Step 2: Add -2 to both sides.
2x+2+−2=y−3+−2
2x=y−5
Step 3: Divide both sides by 2.
2x/2=y−5/2
x=1/2y+(−5/2)
Answer: x=1/2y+(−5/2)
Let's solve for y.
y−3=2(x+1)
Step 1: Add 3 to both sides.
y−3+3=2x+2+3
y=2x+5
Answer:
y=2x+5

Answer:
[tex]y = - 5[/tex]
Step-by-step explanation:
[tex] - 5(y - 3) - 10 = - 6y[/tex]
➡️ [tex] - 5y + 15 - 10 = - 6y[/tex]
➡️ [tex] - 5y + 5 = - 6y[/tex]
➡️ [tex] - 5y + 6y = - 5[/tex]

The profitability, P, of a popular restaurant franchise can be modeled by the function P (t) = t4 – 9t3 + 24t2 – 20t, where t is the number of months since the restaurant opened. How many months after the franchise opens will it begin to show a profit?
5 months
3 months
2 months
1 month
Replace t with the months given as choices to see which one gives a positive value as an answer.
P(1) = 1^4-9(1)^3 + 24(1)^2-20(1) = -4
P(2) = 2^4-9(2)^3+24(2)^2-20(2) = 0
P(3) = 3^4 -9(3)^3+24(3)^2-20(3) = -6
P(5) = 5^4-9(5)^3+24(5)^2-20(5) = 0
P(6) = 6^4-9(6)^3+24(6)^2-20(6) = 96
It shows a profit in month 6 so it would start showing a profit in month 5.
The answer is 5 months
