Answer:
1.5 times
Step-by-step explanation:
450=30 minutes
450*2=900=60 minutes
150=15 minutes
150*4=600=60 minutes
900/600=1.5 times
PB = 12 (P=1, B=2) Numerical values are assigned to each letter and each letter takes on a single number.
Consider the form x^2+bx+c. Find a pair of integers whose product is c and whose sum is b. In this case, whose product is 36 and whose sum is 20.
2, 18
Write the factored form using these integers.
(x+2)(x+18)
Answer:
Step-1 : Multiply the coefficient of the first term by the constant 1 • -8 = -8
Step-2 : Find two factors of -8 whose sum equals the coefficient of the middle term, which is -18 .
-8 + 1 = -7
-4 + 2 = -2
-2 + 4 = 2
-1 + 8 = 7
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
2 • (x2 - 18x - 8)
Its D.
First you find the slope which is (picking any points)
y2-y1/x2-x1
0-4/2-1....slope is -4
using the
y = mx+b plug in points
0 = -4(2) + b
0 = -8 +b
b = 8
