Answer:

  • No, no, yes, yes

Step-by-step explanation:

–10.5 < 3a ⇒ -3.5 < a ⇒ a > -3.5

  • <u>no</u> as variable has positive coefficient

b/6 ≤ 7 ⇒ b ≤ 42

  • <u>no</u> as variable has positive coefficient

–4.5c > 9 ⇒ c < - 2

  • <u>yes </u>as variable has negative coefficient

–21/5 ≤ –5/2d ⇒ (-21/5)*(-2/5) ≥ d ⇒ d ≤ 42/25

  • <u>yes</u> as variable has negative coefficient

B is the midpoint of 2004-01-01-04-00_files/i0420000.jpg. Find the length of 2004-01-01-04-00_files/i0420001.jpg
damaskus [11]
You need to equate the two expressions to get the value of x. That is 3x - 5 = x + 3 and solve for x, you will get x = 4. Then get the length of line ZB and line BA by substituting the value of x you've got; hence line ZB = 3(4) - 5 = 7 and line BA = 4 + 3 = 7. Add the two lines to form a single line ZA, that is 7 + 7 = 14. So the answer is D.14

Help Please, anyone good at domain values of composite functions.
Delicious77 [7]

Answer:

second choice

Step-by-step explanation:

(f \circ g)(x) =

= f(g(x))

= f(-7x + 7)

= \sqrt{-7x + 7 + 3}

= \sqrt{-7x + 10}

Let x = 5:

(f \circ g)(5) = \sqrt{-7(5) + 10}

(f \circ g)(5) = \sqrt{-35 + 10}

(f \circ g)(5) = \sqrt{-25}

Since using x = 5 gives the square root of a negative number, 5 is not in the domain of the composition of the functions.

Answer: second choice
