First we need to isolate the variable so we add 15 to both sides which is
w/4=43  then we need to multiply by 4 to both sides so its 4w=172
then divide by 4 which is 43 so the answer is w=43

Step 1
- w/4 + 15 = 28
-15 -15 (1st)
-----------------------------
(4) -w/4= 13(4) (2nd)
-w=52
Divide both side by -1 to isolate w and you get
W = -52 (Answer)

If we take 24 h, and think that 150 bolts are produced during 1 hour,

then during 24 hours we will get 150*24 = 3600 bolts.

So, y = 150x represent the number of bolts the machine can produce in x hours.

150 bolts/h, and y =150bolts/h *24 h = 3600 bolts

Answer is B.

Is this answer correct?
hodyreva [135]

Answer:

No

Step-by-step explanation:

How to solve :

(a-4)/(a^2+8a+12)*(a^2-2a-48)/(a^2+4a-32)

Factor:

a^2+8a+12 = (a+6)(a+2)

a^2-2a-48 = (a-8)(a+6)

a^2+4a-32 = (a+8)(a-4)

simplify a+6, and a-4

you are left with (a-8)/(a+2)(a+8) = (a-8)/(a^2+10x+16)

What would be the answer to this question. PLEASE EXPLAIN.
Rzqust [24]

You can describe the domain by every possible x value in the function, since that function has a vertical intersection line which means the x value will never pass it on the negative side, the domain would be from -2 to all the postive numbers, X > -2 or (-2,∞).

For the range, simply it's all the possible y values. In that function it's impossible to go under 0 or negative value. That means the range would be Y>0 or (0,∞).

If you want to know if it's a function or not you could try the vertical line test, select any x value and draw straight line on it, if the line crosses 2 y points in the same x value it wont be a function, In your case each x value has it's own Y value.

So the answer is Domain x>-2; Range y>0; Yes, it is a function
