8(2x - 4) = -4(-4x + 8) expand
16x-32 = 16x - 32
this shows x can be ANY value
2 L + 2W = 24 L = 1/3 W
2 (1/3 W) + 2W = 24
W = 9 cm Then L = 3 cm
Area = L * W = 27 cm2
6^(3t - 1) = 36^t.
6^(3t-1) = 6^2t
equate the exponents 3t-1 = 2t
solve fot 't'
Actually......these are " V " shaped graphs......one is inverted They do not intersect at all .
-199 all of the negatives from -98 to -1 cancel out the positives from 1 to 98 and you only have -100 + -99 = -199
Correct !
Pythagorean theorem for right triangle
d^2 = 1^2 + 4^2 solve for d
Initially : 1/4 (j-10) = s+10 or s = 1/4j -12.5
Then 1/2 ( j-34) = s+34 sub in the RED equation above for 's' then solve for j
If she gave away 150, that means there were 150 sets of 3
150 *16 = 150*16 = 2400 - 450*3 = 1050 (450 *3 is the cost of goods sold)
1235- 1050 = 185 at 5 profit each = 37 single copy buyers
