Answer:

y = 3

Explanation:

Any equation of a line that is written as x = # (meaning x equaling whatever number) is vertical on the graph. Therefore, x = -1 is a vertical line. And since x equals -1, all the points on the graph must have an x-value of -1.

We need to find a line that is perpendicular to it - and what would be perpendicular to a vertical line would be a horizontal line. Horizontal lines are represented by the equation y = # (meaning y equaling whatever number). Whatever number is written there is the y-value of all the points the horizontal line intersects.

We know that the line has to pass through (2,3). Therefore, take the y-value of that point - which is 3 - giving us y = 3.

Answer:

$\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7$

Step-by-step explanation:

Given

$\frac{3x^6}{6x^{-1}}$

Required

Solve

In laws of indices, we have:

$\frac{x^m}{x^n} = x^{m-n}$

So, the expression becomes:

$\frac{3x^{6 - (-1)}}{6}$

$\frac{3x^{6 +1}}{6}$

$\frac{3x^7}{6}$

Divide 3 and 6 by 3

$\frac{1x^7}{2}$

$\frac{x^7}{2}$

This can be rewritten as:

$\frac{1}{2}x^7$

Hence:

$\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7$

Can someone show me at least trial one

GenaCL600 [577]

Pick a number: 5
Add 7: 5+7=12
Triple the result: 12*12*12=1728
Add 9= 1728+9=1737
Divide by 3 = 1737/3=579
Subtract original number = 579-5=574

Now pick a different number a do the same process

Hope that helps

A quadratic function has one zero (x-intercept) at x = -5 and another zero at x = 3. What is the equation of the axis of symmetr

liraira [26]

Answer:

x = - 1

Step-by-step explanation:

The axis of symmetry is a vertical line located at the midpoint of the zeros.

Equation is then

x = $\frac{-5+3}{2}$ = $\frac{-2}{2}$ = - 1 , that is x = - 1

Carver jogs four times a wee. Last week, his distances were 4 1/3, 3 1/2, 3 5/6 and 4 1/6, all measured in miles. What was Carve

nevsk [136]

First, it have to change them so that they have common denominators. You would change the denominators to 6.
Your new fractions are:
4 2/6, 3 3/6, 3 5/6, 4 1/6.
Now you add them all together. When you add all of them, you end up with: 14 11/6. You would have to change this to 15 5/6.
Therefore, his average distance was 15 5/6 ( I think? ).
