1. A=(2x)^2-2x*x/2 -2x*x/2=4x^2-x^2-x^2=2x^2

2. A=7x*5x- 4x*3x/2=35x^2-6x^2=19x^2,
    V(5x)^2 - (4x)^2= V(25x^2-16x^2)=V9x^2=3x
3. A=3x*2x-2x*x/2-x*x/2=6x^2-x^2-x^2/2=5x^2-x^2/2=(10x^2-x^2)/2=9x^2/2 =  4.5x^2
4. h=V(5x)^2- (3x)^2/4= V 25x^2-9x^2/4=V100x^2-9x^2/4=V91x^2/4=xV91/2
A=3x*h/2+3x*h/2=6x*h/2=6x/2* xV91/2=6x^2V91/4

Find the equation of a line that contains the points (−2,2) and (−6,−5). Write the equation in slope-intercept form, using fract
mamaluj [8]

Answer:

y = (4/7)X + 22/7

Step-by-step explanation:

Moving from (-2, 2) to (-6, -5), we see that x (the "run") decreases by 4 and y (the "rise") decreases by 7 (from 2 to -5).  Thus, the slope is m = rise / run =

-4/(- 7) = 4/7.  The slope intercept form y = mx + b takes on the specific values 4/7 for m, 2 for y and -2 for x:

2 = 4/7(-2) + b, or 14 = -8 + 7b.  Thus, 22 = 7b, and b = 22/7.

The desired equation is y = (4/7)X + 22/7.
