Let x be the mass of the paperbacks and y be the mass of the textbook.
20x + 9y = 44.4 ----------- (1)
25x + 10y = 51 -------------(2)
(1) x 10:
200x + 90y = 444 --------(1a)
(2) x 9:
225x + 90y = 459 --------(2a)
(2a) - (1a):
25x = 15
x = 0.6 -------- sub into (1)
20 (0.6) + 9y = 44.4
12 + 9y = 44.4
9y = 44.4 - 12
9y = 32.4
y = 3.6
So the paperback's mass is 0.6 pounds and textbook is 3.6 pounds
Answer:
56 times (This is still assuming 1 isnt an option)
Step-by-step explanation:
0,2,3,4,5,6,7,8
There are 8 options, 3 of which are greater than 5
3/8
3/8 = x/150
3*150 = 450
8 * x = 8x
8x = 450
450/8 = 56.25

Answer:
Step-by-step explanation:
given a point
the equation of a line with slope m that passes through the given point is
or equivalently
.
Recall that a line of the form
, the y intercept is b and the x intercept is
.
So, in our case, the y intercept is
and the x intercept is
.
In our case, we know that the line is tangent to the graph of 1/x. So consider a point over the graph
. Which means that 
The slope of the tangent line is given by the derivative of the function evaluated at
. Using the properties of derivatives, we get
. So evaluated at
we get 
Replacing the values in our previous findings we get that the y intercept is

The x intercept is

The triangle in consideration has height
and base
. So the area is

So regardless of the point we take on the graph, the area of the triangle is always 2.

Answer:
552
Step-by-step explanation:
23x + 4y when x=20 and y=23
if x=20 and y=23 all you have to do is replace the numbers and solve
23(20) + 4(23)
Multiply 23*20 which is equal to 460
Then you multiply 4*23 which is equal to 92
The problem is now 460 + 92
add it, and you get 552.
Hope this helps!!
