vova2212 [387]3 years ago
3 0

Answer:

x=1

y=1

Step-by-step explanation:

-3x+4=3x-2

-3x+3x+4=3x+3x-2

4=6x-2

4+2=6x-2+2

6=6x

x=1

y=3(1)-2

y=1

Y = x^2 - 4x + 4<br> Find the discriminant.<br> Determine the number<br> of real solutions.
weqwewe [10]

Answer:

The discriminant is 0

There is 1 real solution

Step-by-step explanation:

Use the discriminant formula, D = b² - 4ac

In the equation y = x² - 4x + 4, a is 1, b is -4, and c is 4.

Plug in these values into the formula:

D = b² - 4ac

D = (-4)² - 4(1)(4)

D = 16 - 4(4)

D = 16 - 16

D = 0

So, the discriminant is 0.

With a discriminant of zero, there is one real solution.

So, the number of real solutions is 1.

((-1)+3)(7) = 14
(2)(7) = 14
14 = 14
True
B is a solution.

((10)+3)(-2) = 14
(13)(-2) = 14
-26 = 14
False
C is not a solution.

((11)+3)(1) = 14
