(3,-1)(4,3)
slope(m) = (3 - (-1) / (4 - 3) = 4/1 = 4
y = mx + b
slope(m) = 4
use either of ur sets of points....(4,3)...x = 4 and y = 3
now sub and find b, the y int
3 = 4(4) + b
3 = 16 + b
3 - 16 = b
-13 = b
so ur equation is : y= 4x - 13 <==
Answer:
C. C is the only one that is rational out of all of them. The rest are irrational
Answer:
They are all right
Step-by-step explanation:
The price of this more expensive book was $90.00 ($150 - $60) based on the date acquired from the question above. This problem can be solved using a simple algebra equation which consisted of one variable. The equation is stated as $150 = x + 1.5x (x = $150/2.5 = $60) where x is the price of the cheaper book and 1.5x is the price of the more expensive books because it has 50% higher price than the cheaper book<span>.</span>
First thing to note, QR + RS = QS
#1, RS = 44.6 and SQ = 68.4
Plug in to the equation I wrote above
QR + 44.6 = 68.4
QR = 23.8
#2, RS = 33.5 and RQ = 80
QR + 33.5 = 80
QR = 46.5
