Answer:
<h2>4</h2>
Step-by-step explanation:
From first piece -6 < x ≤ 0.
From second piece 0 < x ≤ 4.
Therefore -6 < x ≤ 4 → x ∈ (-6, 4]
-7 ∉ (-6, 4]
-6 ∉ (-6, 4]
4 ∈ (-6, 4]
5 ∉ (-6, 4]
Answer:
4(x+2) / 5(x-1)
Step-by-step explanation:
We have given two expressions.
2x / x-1 expression I
5x / 2x+4 expression II
we have to find the quotient of expression I and expression II.
(2x / x-1 ) ÷ (5x / 2x+4)
Applying following rule:
a ÷ b = a× 1/b
(2x/x-1)×( 2x+4 / 5x)
(2x)(2x+4) / (x-1)(5x)
(2)(2)(x+2) / (x-1)(5)
4(x+2) / 5(x-1) which is the answer of given question.
All of them are correct . Number six is 0.28 as a decimal
7 x 4
-- = 28; 0.28 is the answer
25 x 4
F(x) = 4x + 8
Find x in terms of f(x):-
4x = f(x) - 8
x = (f(x) - 8 ) / 4
replace x by h(x) and f(x) by x
h(x) = (x - 8 ) /4
I cant get any of the choices
(7^x)^4 is equal to 7^(4x).
7^2 * 7^3 is equal to 7^(2+3) which is equal to 7^5.
7^5 / 7^(3x) is equal to 7^(5 - 3x).
you wind up with 7^(4x) is equal to 7^(5 - 3x)
this is true if and only if 4x = 5 - 3x.
