Answer:

$10+6(−9−4x)=10(x−12)+8=10−54−24x=10x−120+8=−44−24x=10x−112=−24x−10x=−112+44=−34x=−68x=−34−68x=2$

The area of a square quilt is 196 square inches. There is a smaller square patch on the quilt with an area of 49 square inches.

Makovka662 [10]

To find your answer you would find the perimeter of the small square which is 28.

You would then find the perimeter of the big square which is 56.

Next, you subtract 56 from 28 and get 28.

So the difference is 28 inches.

Hope this helps!!

Sketch the graph of y=x^2-4x+3

NISA [10]

Answer:

see attached graph

Step-by-step explanation:

Given equation: $y=x^2-4x+3$

Standard form of a quadratic equation: $y=ax^2+bx+c$

where $c$ is the y-intercept

If $a > 0$ then the parabola opens upwards.

If $a < 0$ then the parabola opens downwards.

Therefore, the y-intercept of the graph is (0, 3)

To find the x-intercepts, factor the equation:

$y=x^2-4x+3$

$\implies y=x^2-x-3x+3$

$\implies y=x(x-1)-3(x-1)$

$\implies y=(x-3)(x-1)$

Therefore, the x-intercepts of the graph are (3, 0) and (1, 0)

To determine the vertex, differentiate the equation:

$\implies \dfrac{dy}{dx}=2x-4$

Set to zero and solve for x:

$2x-4=0 \implies x=2$

Substitute $x=2$ into the original equation and solve for y:

$\implies y=(2)^2-4(2)+3=-1$

Therefore, the vertex (or turning point) is at (2, -1)
