Answer:
Explanation:
<u>Given Expression</u>:
Use the Quadratic Formula:
<u>insert coefficients</u>
A. The number of fabric-pattern-color combinations is 4 * 13 * 9 = 468
B. P(1st choice) = no of novels / total books = 3/6 = 1/2
P(2nd choice) = no of remaining novels/ total remaining books = 2/5
P(both novels) = 1/2 * 2/5 = 1/5 (without replacement assumed)
C. P(1st choice) = no of biographies / total books = 2/6 = 1/3
P(2nd choice) = no of remaining biographies/ total remaining books = 1/5
P(both biographies) = 1/3 * 1/5 = 1/15 (without replacement assumed)
D. P(1st choice) = no of history books / total books = 1/6
P(2nd choice) = no of novels/ total remaining books = 3/5
P(a history, then a novel) = 1/6 * 3/5 = 1/10 (without replacement assumed)
Answer: YES
<u>Step-by-step explanation:</u>
8p - 2q = 14
8(1) - 2(-3) = 14
8 - -6 = 14
8 + 6 = 14
14 = 14
TRUE
Answer:
7y+5x=76
Step-by-step explan
A (-4,8) and B (6,3)
First find the slope;
m= (y2-y1)/(x2-x1)
m=(3-8)/(3+4)
m=-5/7
now using equation of line
y-y1= m(x-x1)
y-8=-5/7 (x+4)
y-8=(-5x+20)/7
7(y-8)= -5x+20
7y-56=-5x+20
7y+5x=20+56
7y+5x=76
