Terms from greatest to least:
1. 4x3 + 3x2 - x - 4 has four terms
2. 18x2 + 5ab - 6y has three terms
3. X + 2xyz has two terms
4. 9x2yz has one term
96. 120 - 24 = 96. hope i’m not wrong
Answer:
D
Step-by-step explanation:
Given a polynomial f(x) with roots say x = a and x = b, then the factors are
(x - a) and (x - b) and f(x) is the product of the roots, that is
f(x) = (x - a)(x - b)
Here the roots are x = - 4, x = 0 and double root at x = 7
Thus factors are (x - (- 4)), (x - 0), that is (x + 4) and x
Given a double root at x = 7 the factor is (x - 7)², thus polynomial is
y = x(x + 4)(x - 7)² → D
Answer:
y= 28/17
x= 57/17
Step-by-step explanation:
5x + 2y = 22
-2x + 6y = 3
(2)(5x + 2y = 22)→ 10x + 4y = 44
(5)(-2x + 6y = 3)→ -10x +30y = 15
Add this last eq → 34y=56 → y= 28/17
Replace this in any equation
-2x + 6(28/17) = 3 → x= - (54/17-168/17)/2 = 57/17
Answer:
a. 4/13, b. 1/2, c. 3/52, d. 8/13
Step-by-step explanation:
a.
aces in a deck: 4
face cards in a deck: 12
(4+12)/52 = 16/52 = 4/13
b.
even numbers in a deck: 26
26/52 = 1/2
c.
only 3 face cards that are diamonds
3/52
d.
reds in a deck: 26
face cards in a deck: 12
face cards that are red: 6
(26+12-6)/52 = 32/52 = 8/13
