Answer:
- The range of the given function is [6, + ∞)
Step-by-step explanation:
It is assumed the function is:
We know the square root is non-negative, so:
- x - 8 ≥ 0 therefore the function gets values
We can show this as:
Answer: -8x
Step-by-step explanation: to get the answer you would multiply 4x and -2.
4x*-2= -8x
This should be a basic system of equations problem
-------------
12x + 4y = 152
32x + 12y =420
-----------------------
First solve 12x + 4y = 152 for x
Add -4y to each side
<span>12x+4y
+-4y</span>=<span>152
+-<span>
4y
</span></span>12x=-<span>4y+<span>152
</span></span>----------------------------
Divide each side by 12
12x ÷ 12 =
x = -1/3y + 38/3
============================================================
Substitute -1/3y + 38/3 for x in 32x+12y=<span>420
</span>32(-1/3y + 38/3)+12y=420
-------------
Simplify each side
4/3y + 1216/3 = 420
-------------------
Add -1216/3 on each side
4/3y + 1216/3
+ -1216/3 = 420
+ -1216/3
4/3y = 44/3
-------------------------
Divide each side by 4/3
4/3y ÷ 4/3 = 44/3 ÷ 4/3
y = 11
y = 11 is your answer
