hi,
you must replace x by the number between parenthese.
I show you with the first one and let you do the second one
p(x) = 11x^5 -11x^4 - 5x^2 +15x-8
p(-4) = 11 (-4)^5 - 11 (-4)^4 -5(-4)² +15(-4) -8
p(-4) = 11 ( -1024- 256) - 5*16 -60-8
p(-4) = 11 ( -1280) -80-60-8
p(-4) = - 14080 - 148
p(-4) = - 14 228
Answer:
x = -1/2, 3/4
Step-by-step explanation:
Step 1: Isolate everything to 1 side
8x² - 2x - 3 = 0
Step 2: Factor
(4x - 3)(2x + 1) = 0
Step 3: Find roots
4x - 3 = 0
4x = 3
x = 3/4
2x + 1 = 0
2x = -1
x = -1/2
Answer:
150
Step-by-step explanation:
75% of 200 is 150.
75*200=15000
15000/100=150
Each ticket is $35 because you have to divide 175 by 5 and that's how to find the unit rate per ticket.
