Answer:
B. F(x) = 2(x -4)² +4
Step-by-step explanation:
The graph opens upward, so has a positive leading coefficient. (Eliminates choices A and C.)
The graph is translated right 4 units, so x in x² has been replaced by (x-4). (Eliminates choice D.)
The transformed graph is of the equation ...
F(x) = 2(x -4)² +4
-4(7a+5)= —160
distribute the -4 on the left hand side
-4* 7a + -4*5 = -160
-28a +-20 = 160
-28a -20 = -160
add 20 to each side
-28a-20+20 = -160 +20
-28a = -140
divide by -28 on each side
-28a/-28 = -140/-28
a = 5
Answer: a=5
It would be 9 flowers because 4 times 9 equals 36 which means that each arrangement would have an even amount.
Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.
Answer:
7a+b-9c+17d
Step-by-step explanation:
-5 ( a-2b+3c -4d) - (-3) (4a -3b+2c-d)
Distribute
-5a+10b-15c+20d+12a-9b+6c-3d
Combine like terms
7a+b-9c+17d
