Evaluate the difference quotient for the given function. Simplify your answer. f(x) = 1 x , f(x) − f(a) x − a
Answer:
[tex]\frac{f(x) - f(a)}{x - a}=\frac{-1}{xa}[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \frac{1}{x}[/tex]
Required
Evaluate [tex]\frac{f(x) - f(a)}{x - a}[/tex]
We have:
[tex]f(x) = \frac{1}{x}[/tex]
Next, we calculate f(a)
Substitute a for x in [tex]f(x) = \frac{1}{x}[/tex]
[tex]f(a) = \frac{1}{a}[/tex]
Substitute values for f(x) and f(a) in [tex]\frac{f(x) - f(a)}{x - a}[/tex]
[tex]\frac{\frac{1}{x} - \frac{1}{a}}{x - a}[/tex]
Take LCM of the numerator
[tex]\frac{\frac{a - x}{xa} }{x - a}[/tex]
Split:
[tex]\frac{a - x}{xa} /{x - a}[/tex]
Convert / to *
[tex]\frac{a - x}{xa} *\frac{1}{x - a}[/tex]
Express a - x as -(x-a)
[tex]\frac{-(x - a)}{xa} *\frac{1}{x - a}[/tex]
Divide numerator and denominator by x - a
[tex]\frac{-1}{xa} *\frac{1}{1}[/tex]
[tex]\frac{-1}{xa}[/tex]
Hence:
[tex]\frac{f(x) - f(a)}{x - a}=\frac{-1}{xa}[/tex]
Roberto rented a truck from the Super Truck Company for 9 hours. There was a rental fee of $50. Allison rented a truck from Trucking America for 4 hours. She paid a $110 rental fee. Both Roberto and Allison spent the same amount and both companies have the same hourly rental fee. Write and solve an equation to determine the hourly rental fee.
Answer:
Hence, the hourly rental fee is [tex]\$\: 12[/tex].
Step-by-step explanation:
Time for which Roberto rented the truck [tex]=9[/tex] hours.
Rental fee [tex]=\$ \:50[/tex]
Time for which Allison rented the truck [tex]=4[/tex] hours.
Rental fee [tex]=\$ \:110[/tex]
Both companies have the same hourly rental fee.
Let the hourly rental fee of both the companies be [tex]x[/tex].
Both spent the same amount.
So, according to the question,
[tex]\Rightarrow 50+9x=110+4x[/tex]
[tex]\Rightarrow 9x-4x=110-50[/tex]
[tex]\Rightarrow 5x=60[/tex]
[tex]\Rightarrow x=\frac{60}{5}[/tex]
[tex]\Rightarrow x=12[/tex]
Hence, the hourly rental fee is [tex]\$\: 12[/tex].

Step-by-step explanation: OK, so look there are four people wanting to run for president and vice presdent so Todd and Jenna are running for a school club Todd has a higher chance of getting one of the two positions because if people vote enough for Todd to get the president position and has a change of getting vice president so If Jenna get lots of vote for (P) then she will run for (P) but if not flip flop Todd and Jenna positions and one of them go to get some position or if not the candidates move up a step.
A railroad car container can hold 66,000 pounds. Mr. Evans wants to ship 80 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers could be shipped in the container. Each oven
weighs
300 pounds
Answer:
70 freezersStep-by-step explanation:
Each oven weights 300 pounds and there 80 ovens:
80*300 = 24000 poundsWeight left for freezers:
66000 - 24000 = 42000 poundsNumber of freezers could be added:
42000/600 = 70What is M - 3 > -2???
Answer:

Which expression shows the area of the shaded part of the grid? A hundred grid model showing a 7 4 array shaded blue. A. 0.04 × 0.07 B. 0.5 × 0.7 C. 0.4 × 0.7 D. 0.3 × 0.6
Answer:
[tex]C.\ Area = 0.4 * 0.7[/tex]
Step-by-step explanation:
See attachment for grid
From the attachment:
There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.
This implies that, the measurement of each cell is:
[tex]Each\ Cell = \frac{10}{10 * 10}[/tex]
[tex]Each\ Cell = \frac{1}{10}[/tex]
[tex]Each\ Cell = 0.10[/tex]
The horizontal axis has 7 selected cells.
This measures
[tex]Horizontal = 7 * 0.10 = 0.70[/tex]
The vertical axis has 4 selected cells.
This measures
[tex]Vertical = 4 * 0.10 = 0.40[/tex]
So, the selected area is:
[tex]Area = Vertical * Horizontal[/tex]
[tex]Area = 0.40 * 0.70[/tex]
or
[tex]Area = 0.4 * 0.7[/tex]

B. 4(2x + 2)(x - 1)
O C. 4(2x + 3)(x - 1)
D. 4(2x + 1)(x-8)
Answer:
A. [tex]4(2x+1)(x-2)[/tex]
Explanation:
[tex]8x^{2} -12x-8[/tex]
1. You can factor out a 4.
[tex]4(2x^{2} -3x-2)[/tex]
2. Factor [tex](2x^{2} -3x-2)[/tex].
X-Method:
1. Draw an X
2. Multiply ac (2(-2)=-4) then put it in the top part of the X
3. Then put b, -3, in the bottom part of the X
4. On the two sides of the X find out what added together equals b, -3,
and multiplied equals ac, -4.
5. -4(1)=-4 & -4+1=-3
6. If the quadratic has a coefficient then you must divide the two sides
of the X by that coefficient, 2.
7. -4/2=-2 & 1/2 can't be evenly divided into, so in this case the
coefficient remains.
8. When you write this out it will be (2x+1)(x-2)
3. Put it together to get your answer.

In this exercise we have to use the knowledge of parabolas to describe the value, in this way we have to:
Letter C
In this exercise we are dealing with a parabola and we can solve it just by looking at the values and the graph, so:
When we have a parabola, its peak relates to the highest profit value on the Y axis, so we find the profit of 150 dollars when the X axis represents the value of the toy in 6 dollars.See more about parabola at brainly.com/question/8495504
Please help!!! Geometry
Answer:
x=26
Step-by-step explanation:
We can use the Pythagorean theorem for this answer.
Pythagorean Theorem: a^2 +b^2 = c^2
We can see that both triangles are right triangles. We should first find the hypotonus of the bottom triangle.
So, we plug in the values.
6^2 +8^2 = c^2
36 +64 = c^2
c^2= 100
c= square root of 100
c=10
The hypotonus for the bottom triangle is equivalent to the base of the top triangle. Therefore, we can use the Pythagorean Theorem again.
10^2 +24^2= c^2
100+576+c^2
c^2 = 676
c= square root of 676
c= 26
The answer to the problem is 26.
Factorise 2xsquared X 7x +3
Answer:
(-2x - 1) • (x + 3)
Step-by-step explanation:
3.2 Factoring 2x2 + 7x + 3
The first term is, 2x2 its coefficient is 2 .
The middle term is, +7x its coefficient is 7 .
The last term, "the constant", is +3
Step-1 : Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2 : Find two factors of 6 whose sum equals the coefficient of the middle term, which is 7 .
-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 6
2x2 + 1x + 6x + 3
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x+1)
Add up the last 2 terms, pulling out common factors :
3 • (2x+1)
Step-5 : Add up the four terms of step 4 :
(x+3) • (2x+1)
Which is the desired factorization
chance rolls a 1-6 number cube. What is the probabilty that he will roll a prime number
Answer:
B
Step-by-step explanation:
There are six numbers altogether. 2 3 and 5 are prime. One is odd, but it is not considered prime.
So P(prime) = 3/6 = 1/2
As a percent, this is 1/2 * 100 = 50%
Which equation matches the hanger?
O X+3=6
0 3x = 6
0 6 = 3x +1
2x = 6
Answer:
B. 3x = 6
Step-by-step explanation:
The left side of a hanger is on the left side of the equation, and the right side of a hanger is on the right side of the equation.
There are 3 x's on the left side, so the left side is 3x
The right side shows 6 unit boxes, so the right side is (1 * 6), or 6.
As a result, the equation is 3x = 6, which is B.
