This equation shows how the length of Rob's essay depends on the number of hours he spends writing this week. p = h + 11 The variable h represents the number of hours he spends writing this week, and the variable p represents the total number of pages that have been written. How many hours will Rob have to spend writing this week in order to have written a total of 16 pages?

Answers

Answer:

Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.

Step-by-step explanation:

From the information given, you can use the formula p=h+11 and solve for h. Then, you have to replace p with 16 to get the amount of hours that Rob will have to spend writing this week in order to have written a total of 16 pages:

p=h+11

h=p-11

h=16-11

h=5

According to this, the answer is that Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.

Answer:

y = -1/4x-6

Step-by-step explanation:

y=mx+b

Use slope equation m = (y1 - y2) / (x1 - x2)

b is the y intercept : -6

Answer:

y=-1/4x+(-6)

Step-by-step explanation:

Slope intercept form is y=mx+b. To find the slope, pick 2 points the line crosses through and divide the rise by the run. You can see the y-intercept on the graph. Therefore the equation should be y=-1/4x+(-6).

17 What are the x-intercept to the function f(x)=2x-31+2 ?
A {0}
B{-5/2,5/2}. C{ } D{-5/2,-1/2}

Answers

Answer:

See below

Step-by-step explanation:

It seems to be a typo.

[tex]f(x)=2x-31+2[/tex]

[tex]f(x)=2x-29[/tex]

The x-intercept is when the function is equal to zero. Once the function is linear, there will be one x-intercept.

[tex]0=2x-29[/tex]

[tex]x=\dfrac{29}{2}[/tex]

Once there are alternatives with two values, your function  is probably a quadratic function.

[tex]f(x)=2x^2-31x+2[/tex], but the roots are not in the alternatives.

Given that 7x - 3y = 23
Find when y = -2
Give your answer as an improper fraction in its simplest form.​

Answers

7x - 3(-2) = 23
7x - - 6 = 23 (two minuses make a plus)
so it’s gonna be 7x + 6 = 23
Now you have isolate you x, so move everything else to the other side, but remember to change your sign when transferring to the other side

7x = 23 - 6
7x = 17
To isolate x in this multiple, you divide by 7 (because the inverse of multiplication is division)
x = 17/7

If f(x)=13x3−4x2+12x−5 and the domain is the set of all x such that 0≤x≤9 , then the absolute maximum value of the function f occurs when x is

Answers

The correct format of the question is

If f(x)= [tex]\frac{1}{3}x^3 -4x^2+12x -5[/tex] and the domain is the set of all x such that 0≤x≤9 , then the absolute maximum value of the function f occurs when x is

Answer:

The absolute maximum value of the function F(x) occurs when x is 9

Step-by-step explanation:

F'(x) = [tex]x^2 -8x +12= 0[/tex]

      = (x-6)(x-2) = 0

      x = 2,6

so we have boundary points 0 , 9 and 2,6

The value of function at these four points

  x =     0    2       6     9

F(x) =  -5    17/3   -5     22

So the absolute maximum value of the given function is x = 9 and F(x) is 22.

The absolute maximum value of the function f occurs when x is 9 and this can be determined by differentiating f(x) and then equating it to zero.

Given :

[tex]\rm f(x)=\dfrac{1}{3}x^3-4x^2+12x-5[/tex]The domain is the set of all x such that 0≤x≤9

In order to determine the absolute maximum value of function f(x), differentiate f(x) and then equate it to zero.

[tex]\rm f'(x)=\dfrac{1}{3}\times(3x^2)-8x+12[/tex]

Now, equate the above equation to zero.

[tex]x^2-8x+12 = 0[/tex]

Factorize the above quadratic equation.

[tex]x^2-6x-2x+12=0[/tex]

x(x - 6) - 2(x - 6) = 0

(x - 6)(x - 2) = 0

Now, determine the value of f(x) at x = 0, 2, 6, 9

f(0) = -5

f(2) = 1/3.(8) - 4(4) + 12(2) - 5

f(2) = 17/3

f(6) = 72 - 144 + 72 - 5

f(6) = -5

f(9) = 243 - 324 + 108 - 5

f(9) = 22

So, the absolute maximum value of the function f occurs when x is 9.

Answer: -3 for the exponent box

Step-by-step explanation: Hi there! Let's get started.

We know that a negative exponent is going to decrease by a power of 10 every time for example 10 x 10^-1 = 1 because the -1 says we need to move the decimal point one to the left.

So with this we take 2.345 x 10^-3 = 0.002345.

We moved the decimal point 3 to the left from 2.345 to get 0.002345.

step one:

given data

we are told that 2 1/4( 2.25 pound) of candy cost $8

let us find the cost of 1 pound first

so

2.25 pound cost  #8

1 pound will cost x

cross multiply

x=8/2.25

x=$3.55 for one pound.

step two:

Hence  if 1 pound cost $3.55

4 pound will cost = 3.55*4= $14.22
