Answer:

B , C ,E

Step-by-step explanation:

Open the brackets

= -8+6x+5x-2

= -8+11x-2

= 11x-10

options. E, C and B respectively

Answer:

(B). 11x - 10 ; (C). - 8 + 11x - 2 ; (E). - 8 + 6x + 5x - 2

Step-by-step explanation:

- 2(4 - 3x) + (5x - 2) = - 8 + 6x + 5x - 2 = - 8 + 11x - 2 = 11x - 10  

Answer:  -3 bc the exponent is adding -1 each time

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.

Hope this helps! :)

A: Speed is Independent as it can be anything with no restrictions. Gas mileage is dependent as it relies on the value of speed for its value to be decided.

B: The first letter of speed is "S" so it can represent the variable. The first letter of mileage is "M" so the variable can be represented by that letter. It really can be any letter.

C: no context

D: no context

A: Speed is pretty cool becuase speed has no restrictions.

B: It can be any number.

Answer: $52.41

Step-by-step explanation:

Cost before tax = $42.20

Sales tax = $2.21

Tip = $8

The total amount spent by Mrs Smith at Red Lobster will be:

= Cost before tax + Sales tax + Tip

= $42.20 + $2.21 + $8

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.

Answer:

the answer is BE

Step-by-step explanation:

skews are lines that dont intersect or arent parallel to each other

in that case BE or CF are correct but BE is the only answer choice that works... hope it works

The line segment skew to GH is BE.

Skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron.

Given is a rectangular prism, with vertices, A, B, C, D, E, F, G and H

We are asked to identify a line segment which is skew to GH,

In the given options, EF, AD are BC are parallel to GH hence not skew, but line segment BE is neither parallel nor perpendicular to GH.

Hence, the line segment skew to GH is BE.

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).

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.

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 :

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.

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
