X-intercepts
f(x) = 0
4x² - 15x - 4 = 0
4x² - 16x + x - 4 = 0
4x(x - 4) + 1(x - 4) = 0
(x - 4)(4x + 1) = 0 ⇔ x - 4 = 0 or 4x + 1 = 0
x = 4 or 4x = - 1 ⇒ x = - 1/4
Answer: -1/4 and 4.
Step-by-step explanation:
3k + 2k - 6 = 8k + 3
8k - 3k - 2k = - 6 - 3
8k - 5k = -9
3k = - 9
k = - 9/ 3
K = - 3

Step-by-step explanation:
A. 75 x 0.0016= .12 Has a value between 0 and 1
B. 3^5 / 3^-6 = 177147 Does not a value between 0 and 1
C. 1/4^3 x 1/4^2 = about 0.0009 Has a value between 0 and 1
D. -7^5 / -7^7 = about 0.02 Has a value between 0 and 1
Answer:
5000x^2 is the 4th term
Step-by-step explanation:
ok, 1 bionimial theorem coming right up
for a binomial expansion of (a+b)^n
the kth term is
means
n is 5
4th term
4-1=3
and a=2x
b=5
so
(10)(4x^2)(125)
5000x^2 is the 4th term
