(y - y1) = m (x -x1)
( y - 5/2) = -1/2 (x - -2)
(y - 5/2) = -1/2 ( x + 2)
y - 5/2 = -1/2 x - 1
y = -x/2 - 1 + 5/2
y = -x/2 - 2/2 + 5/2
y = -x/2 + 3/2
Answer:
1. 2x² - 8x - 7
2. x³+ x + 30
Step-by-step explanation:
Answer:
x +2y = 36
2x+3y =64
Step-by-step explanation:
x = price of a T-shirt
y = price of a puck
Adam buys a T-shirt and two souvenir pucks for $36.00
x +2y = 36
Luke spends $64.00 on two T-shirts and three pucks
64 = 2x+3y
Our system of equations is
x +2y = 36
2x+3y =64
C -20/27 because 5x-8= -40 and 9x6= 54 and u divide both numbers by two and get C
Answer:
P (arts) = 0.25
P (psychology) = 0.25
P (geology) = 0.5
Step-by-step explanation:
Let the probability of choosing art = x
As given that she is equally likely to choose art or psychology and twice as likely to choose geology.
So,
P (arts) = x = P (psychology)
P (geology) = 2x
The sum of the probability = 1
So,
P (arts) + (psychology) + P (geology) = 1
x + x + 2x = 1
<u>x = 0.25</u>
<u>P (arts) = x = 0.25</u>
<u>P (psychology) = x = 0.25</u>
<u>P (geology) = 2x = 2*0.25 = 0.5</u>
