Solve the system by substitution. y=x2 – 2x+1 y= 2x+1

Mathematics
1 answer:
mafiozo [28]3 years ago
6 0

Answer:

(0 , 1), (4, 9).

Step-by-step explanation:

y = x2 – 2x+1

y = 2x+1

Substitute y = 2x + 1 into the first equation.

2x + 1 = x^2 - 2x + 1

x^2 - 2x - 2x  = 0

x^2 - 4x = 0

x(x - 4) = 0

x  = 0, 4.

When  x = 0, y = 1.

When x = 4, y = 8 + 1 = 9.

Write the equation 9y = 12x + 0.2 in standard form. Identify A, B, and C.
uysha [10]

Answer:

A = -12, B = 9 and C = .2

Step-by-step explanation:

So it just looks like we need to use algebra to move everything around to get it in the form Ax + By = C

So, let's start with 9y = 12x + 0.2.  From standard form we have all terms wth variables on one side, so let's do that.  the right sie has both a variable term and non variable term, so let's get rid of the variable term.  The variable term is 12x, so to get rid of it you subtract 12x from both sides.

9y = 12x + 0.2

9y - 12x = 0.2

To make it exactly in standard form just rarrnge.

-12x + 9y = 0.2

So now we have A = -12, B = 9 and C = .2
