Write the slope-intercept form of the equation of each line.
gregori [183]

Greetings!

Answer:

2y = x - 6

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -2x, the slope of this line is -2

When finding the slope of a line perpendicular, you need to find the \frac{-1}{slope}

So, in this case it is:

\frac{-1}{-2}

The negatives cancel out which leave \frac{1}{2}

So the gradient is \frac{1}{2}


Now, to find the equation of a line, you need to use:

y - y1 = m(x - x1)

Where ya and x1 are the values in the coordinates (2 , -2)

So y1  = -2, x1 = 2, and m is a half. Plug these values in:

y - - 2 = \frac{1}{2}(x - 2)

We need to get rid of the half so we multiply the whole equation by 2:

2y - - 4 = (x - 2)

The minus and the negative turn into a positive:

2y + 4 = x - 2

And now simply move the +4 over to the other side, making it a negative:

2y =  -2 - 4 + x

Simplify:

2y = x - 6

<h3>So the equation of the line is 2y = x - 6</h3>

Dora drove 80 km in 40 minutes then 120 km in 1 hour and then the final 200km took him 1 hour 20 minutes. what is his average sp
bonufazy [111]

9514 1404 393

Answer:

  133 1/3 km/hour

Step-by-step explanation:

Average speed is computed as ...

  average speed = (total distance)/(total time)

  = (80 km +120 km +200 km)/(2/3 + 1 + 1 1/3 hour) = 400 km/(3 hour)

  = 133 1/3 km/hour

nadya68 [22]

Answer:

x = 9

Step-by-step explanation:

7x - 1 = 62

add  on to each side and you get 7x = 63

Which of the following is equal to the function below? (7/4)^11
solmaris [256]

Answer:

Therefore the correct option is A. 7^11/4^11

(\dfrac{7}{4})^{11}=\dfrac{7^{11}}{4^{11}}

Step-by-step explanation:

Given:

(\dfrac{7}{4})^{11}

Solution:

We know the Identity For Law of Indices

(\dfrac{x}{y})^{a}=\dfrac{x^{a}}{y^{a}}

So here we have,

x = 7

y = 4

a = 11 , then

(\dfrac{7}{4})^{11}=\dfrac{7^{11}}{4^{11}}

Therefore the correct option is A. 7^11/4^11

(\dfrac{7}{4})^{11}=\dfrac{7^{11}}{4^{11}}
