Its C. Add 3 and 15 which gives you 18. Then move the variable (4x) to the left. Then combine like terms which are the x’s and you should get 3x. Then divide both sides by 3. (18/3 = 6)

Answer:

y = 3/5x - 1

Step-by-step explanation:

The slope found from counting the units is 3/5, and the y-intercept is -1, hence 3/5x - 1

Using principle of mathematical induction prove that 6^-1 divisble by 5 .

salantis [7]

I suppose the claim is $5 \mid 6^n - 1$ for $n\in\Bbb N$ .

When $n=1$ , we have $6^1 - 1 = 6 - 1 = 5$ , and of course 5 divides 5.

Assume the claim holds for $n=k$ , that $5 \mid 6^k - 1$ . We want to use this to show it holds for $n=k+1$ , that $5 \mid 6^{k+1} - 1$ .

We have

$6^{k+1} - 1 = \left(6^{k+1} - 6\right) + \left(6 - 1) = 6\left(6^k - 1\right) + 5$

Since $5 \mid 6^k - 1$ , we can write $6^k - 1 = 5\ell$ for some integer $\ell$ . Then

$6^{k+1} - 1 = 6\cdot5\ell + 5 = 5(6\ell + 1)$

which is clearly divisible by 5. QED

Arrange the parabolas with respect tonthe postion of their vertices from left to right

agasfer [191]

Answer:

The correct answer for this question is this one:

If the x position of the vertex for f(x) is k then :

1. f(k) => 4x+3=k, x = (k-3)/4 = (k/4)-(3/4)

2. x = k+3

3. x = (k+1)/2 = (k/2)-(1/2)

4. x = 2(k+2) = 2k+4

5. x = k+7

6. x = k-3

7. x = k-2

So the order depends on the original position of the vertex k, e.g for k=0 the positions would be:

1. -3/4

2. 3

3. -1/2

4. 4

5. 7

6. -3

7. -2

So, therefore, the order would be 6 7 1 3 2 4 5

What is the slope of this line? y=4x+6

ruslelena [56]

Answer:

The slope is 4

Step-by-step explanation:

So the formula is y=mx+b. M is the slope and b would be your y intercept. So the slope is 4. (I just did this in class)
