In section C it seems that the car is Slowing down.

In the graph you see the 0 in the corner the numbers going up are getting higher and the numbers going to the side are going higher up. In section be he is going constantly the same speed, which is also the fastest he goes. Then he starts going slower in section C.

Therefore the answer is his car is slowing down
Hope this helps!!! :)

For any value of x, the sum <br> 3<br> ∑ k(2x-1) <br> k=0<br> is equivalent to

MArishka [77]

The equivalent value of the sum for any value of "x" is 12x - 6

<h3>How to find the sum of functions?</h3>

Given the sum of the expression as:

∑ k(2x-1)

k=0

We need to take the sum of the function at the point where k = 0 to 3

∑ k(2x-1) = 0(2x-1) + 1(2x - 1) + 2(2x-1) + 3(2x - 1)

k=0

∑ k(2x-1) = 2x-1+4x-2+6x-3

k=0

∑ k(2x-1) = 12x - 6

k=0

Hence the equivalent value of the sum for any value of "x" is 12x - 6

Factorise:b+√b-12<br>An easy one.

aalyn [17]

Answer:

Step-by-step explanation:

If you let b = x^2 the problem becomes a whole lot easier. Note that x = √b

x^2 + x - 12

Now factor this trinomial.

(x + 4)(x - 3)

Now put b back into the equation

(√b + 4)(√b - 3)

Hannah was asked to make d the subject of the formula<br> d-7=4d+3/e<br> Finish her question.

tigry1 [53]

Answer:

$d = \frac{-1}{e} - \frac{7}{3}$

Step-by-step explanation:

In order to make d the subject of the formula, you need to isolate it.

- You started with d-7 = 4d + 3/e

- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...

d - 7 = 4d + 3/e This will leave you left with -3d - 7 = 3/e

-4d -4d

- Then move over the -7 by adding 7 to both sides...

-3d - 7 = 3/e This will leave you left with -3d = 3/e + 7

+7 +7

- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...

$d = \frac{3}{-3e} -\frac{7}{3}$

- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be

$d = \frac{-1}{e} - \frac{7}{3}$
