Uh sure what type of cereal?
Answer:
(4,12)
(-1,-3)
Step-by-step explanation:
x^2 - y = 4
y = 3x
Use substitution. Substitute 3x for y in the first equation
x^2 - (3x) = 4
x^2 -3x =4
Subtract 4 from each side
x^2 -3x -4 = 4-4
x^2 -3x-4 =0
Factor
(x-4) (x+1) =0
Using the zero product property
x-4 =0 x+1 =0
x=4 x=-1
Now to find y for each x solution
x=4
y =3x = 3(4) =12
(4,12)
x=-1
y =3x = 3(-1) =-3

Answer:
The cost for making x banjos is c = $ 400 x
Step-by-step explanation:
Given as :
The making cost of each banjos = $ 250
The selling cost of each banjo = $ 400
Let The cost for making x banjos = c
Now,
∵ For making 1 banjos , the making cost = $ 250
∴ For making x banjos , the making cost = $ 250 × x
Again,
∵ The selling price of 1 banjos = $ 400
∴ The selling price of x banjos = = $ 400 × x
Hence The cost for making x banjos is c = $ 400 x . Answer
Answer:
y - 3 = - 2(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 2 and (a, b) = (1, 3) , thus
y - 3 = - 2(x - 1) ← in point- slope form
