What is the slope of the line that passes through the points (4, -7) and (9, 1)?

1 answer:

8 0

The slope of an equation passing though the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(4,-7) and (9,1)

slope=(1-(-7))/(9-4)=(1+7)/5=8/5
slope=8/5

pshichka [43]

Answer:

x = 10 , -12

Step-by-step explanation:

Solution:-

- The given quadratic equation is to be solved using the quadratic formula. The general form of a quadratic equation is:

$ax^2 + bx + c =0$

Where, [ a , b and c are constants ]

- The quadratic formula is given as:

$x = \frac{-b+/-\sqrt{b^2 - 4*a*c} }{2a}$

- The given equation is:

$x^2 + 2x - 120 = 0$

Where, a = 1 , b = 2 , c = -120

- Solve using quadratic formula:

$x = \frac{-2+/-\sqrt{2^2 - 4*1*(-120)} }{2*1}\\\\x = \frac{-2+/-\sqrt{4 + 480} }{2}\\\\x = \frac{-2+/-(22) }{2}\\\\\\x = 10 , -12$

PLEASE HELP ASAP! Find the area of quadrilateral ABCD in each case.

Arisa [49]

Answer:

The area is 5 units²

Step-by-step explanation:

∵ The area of the square of side length 3 which contains

the quadrilateral ABCD = 3 × 3 = 9 units²

∵ The area of the 4 triangles on the sides of the quadrilateral ABCD

= 1/2(2)(1) + 1/2(1)(2) + 1/2(2)(1) + 1/2(1)(2) = 4 units²

∴ The area of quadrilateral ABCD = 9 - 4 = 5 units²
