Answer:

y = 2x - 1

Step-by-step explanation:

y2 - y1 / x2 - x1

-5 - (-3) / -2 - (-1)

-2/-1

= 2

y = 2x + b

-3 = 2(-1) + b

-3 = -2 + b

-1 = b

Simplify the expression x^2+x-2/8x^2+4x/3x^2+10x+8

irina [24]

Answer:

Step-by-step explanation:

x² + x - 2 = x² - x +2x -2 = x(x - 1) + 2*(x-1) = (x-1)(x+2)

8x² + 4x = 4x ( 2x + 1)

3x² + 10x + 8 = 3x² + 6x + 4x + 4*2 =3x * (x + 2) + 4 * ( x + 2) = (x + 2)(3x + 4)

A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the

Alexeev081 [22]

Answer:

Answer choice A) About 38.47 square units

Step-by-step explanation:

Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:

$\dfrac{22}{2\pi}\approx 3.503$

Since the area of a circle is $\pi r^2$ , the area of this circle is:

$\pi \cdot 3.503^2= 3.14\cdot 12.271\approx 38.47$

Hope this helps!
