Solving this system of equations without a CAS: $4=a+c$, $5=d+ac+b$, $4=ad+bc$, $4=bd$ 2

Let $A,B,C,D$ be the vertices of a four sided polygon taken in anti clockwise. Given $|AB|=|BC|=3,|AD|=|CD|=4,|BD|=5$ , Find $|AC|$ 1

Find $ad - bc$ if $ac = 18$ and $bd = 50$ 2

1-2+3-4+5-6+..+99-100.
aliya0001 [1]
-50

So you want to pair them up
(1-2)+(3-4)+(5-6)..+(99-100)
And write the answer for each pair
(-1)+(-1)+(-1)..+(-1)
When looking at this you can see that each pair equals -1
So you divide 100 by 2 and multiply that by the -1
100/2=50
50*-1=-50
Answer is 50


You would use the same method if you were going up to a number like a 500
The answer would be -250

AURORKA [14]
DONT CLICK ON THE LINKS! It’s 8.750 BY THE WAY the radius is half the diameter so just add the radius by itself or multiply by 2

Slope intercept y = 2/3x + 4. plz explain how i find x
White raven [17]
The equation: y = 2x/3 + 4 is a line with infinite values for x. So unless you have a y-value to plug in to find the corresponding x-value all you can do is write the equation in terms of y.

x = 3(y-4)/2

The slope and intercepts on the other hand can be determined from the given equation. y= mx + b is slope-intercept form of a linear equation. "m" is the slope and "b" is the y-intercept. Plug in y = 0 to find the x-intercept.
