Answer:
320 pound
Step-by-step explanation:
Ratio is decently easy after u understand the concept
So... This is what the question gave
Jupitar : earth
8 : 3
In other words, if u weigh 8 pound on Jupitar, u would weigh 3 pounds on earth
Therefore now they say on earth, the person weighs 120 pound, so let's just put in this value
Jupitar : earth
8 : 3
? : 120
Now its called ratio bcuz the increase at the same pace
So now look at the earth part, u got to find out how did 3 become 120, so just divide them
120/3 = 40 , so 3 x 40 = 120
So if they multiplied the right ( earth) by 40, u do the exact same on the left ( Jupitar)
8 x 40 = 320
Thats your answer my friend
(a) how much potting soil he bought last week
(b) 28 = 2p + 4
(c) 28 = 2p + 4....subtract 4 from both sides
28 - 4 = 2p...simplify
24 = 2p...divide both sides by 2
24/2 = p....simplify
12 = p......12 solves the equation
(d) He bought 12 lbs of potting soil last week
Not sure sorry I will look at it again though
Answer:
- The instantaneous rate of increase of f(x) at
is 3. - One possible equation of this line is y = 3x - 16.
- The line is tangent to the graph of y = f(x). The slope of the line is the same as the instantaneous rate of increase of f(x) at .

In other words, the graph of y = f(x) passes through the point (3, -7) where 
.
The point-slope form of a line in a cartesian plane is:
.
For this line,
is the point on the line, while
is the slope of the line.
The equation of this line will thus be
.
That's equivalent to
.
<h3>3.</h3>
Refer to the diagram attached. The line touches the graph of y = f(x) at x = 3 without crossing it. The line here is thus a tangent to the graph of y = f(x) at x = 3. The slope of the line represents the instantaneous rate of increase of f(x) at .
