Answer:

x = -24

a = 11

Step-by-step explanation:

So for the first one:

-\frac{1}{4} x+6=\frac{2}{3} x+28

Multiply both sides of the equation by 12

-3x+72=8x+336

Subtract 8x from both sides

-11x+72=336

Subtract 72 from both sides

-11x=264

Divide both sides by -11

x=-24

And the second one...

2(a-2)=3(a-5)

Distribute the 2 to the (a - 2) and the 3 to (a - 5)

2a-4=3a-15

then add 15 to both sides

2a+11=3a

Subtract 2a from both sides

11 = a

Which of the following graphs could be the graph of the function f(x) = x4 + x3 – x2 – x?
vitfil [10]

<u> Solution-</u>

The given function is,

f(x) = x^4+ x^3-x^2-x

     = x^3(x+1)- x(x+1)

     = (x+1)(x^3-x)

     = (x+1)x(x^2-1)

     = (x+1)x(x+1)(x-1)

     = {(x+1)}^2x(x-1)

Therefore, at x=0, -1, 1 , f(x) will be 0 . Hence, 0, -1 ,1 are the x-intercepts.

Plotting the graph on desmos, the graph will be as in the attachment.

Whats the slope for 11x=2y-5
zhannawk [14.2K]
11x = 2y - 5
11x + 5 = 2y
2y = 11x + 5                    (<u>a</u>x + b form)
y = (11x + 5)/2
y = 11x/2 + 5/2

The slope is <u>11/2</u>

To rent a moving truck there is a fee of $150 and each mile you drive costs an extra $1.75 per mile, where R(x) is the total cos
abruzzese [7]

Answer:

$318

Step-by-step explanation:

First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be R(x)=. Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.

R(x)=150+1.75x

The problem tells us that we are driving 96 miles, so we can plug in 96 for x and solve.

R(x)=150+1.75(96)\\R(x)=150+168\\R(x)=318

The total cost of the rental is going to $318.

Hope this helps!
