Rates are used to show how a quantity measures over another.

Andy does not read at a constant rate.

The table is given as:

\left[\begin{array}{cccccc}x&10&20&30&40&50\\y&4&9&10&15&20\end{array}\right]

Pick any two points from the table:

(x_1,y_1) = (10,4)

(x_2,y_2) = (20,9)

The rate (m) is then calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

So, we have:

m = \frac{9-4}{20-10}

m = \frac{5}{10}

m = 0.5

Pick another point from the table

(x_1,y_1) = (10,4)

(x_2,y_2) = (30,10)

The rate (m) is then calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{10 - 4}{30 - 10}

m = \frac{6}{20}

m = 0.3

The rates calculated are not equal

<em>i.e. 0.3 and 0.5 are not equal</em>

This means that;

Andy does not read at a constant rate.

Assume each figure shown has the same orientation. Which figure is the image of square LMNP after a translation of
umka21 [38]

Figure 4 is the image of the square LMNP after the translation.

<u>Step-by-step explanation:</u>

Let us see the coordinates of the pre image LMNP as,

L (-3,1)

M(-1,1)

N(-1,-1)

P(-3,-1)

after translation of (x,y) → (x+5, y -3) the coordinates of the image obtained as,

L'(2,-2)

M'(4,-2)

N'(4,-4)

P'(2,-4) which matches the image 4.

I need help PLEASSEE
nadya68 [22]
We know that perpendicular lines have slopes which are negative inverses of each other. This means that the slope of the line we are going to need to find is 3.

Now, we can use the point-slope formula to find the actual equation of the line we are trying to find. The point-slope formula is (y - y_1) = m(x - x_1), where y_1 and x_1 are the coordinates of a point on the line and m is the slope. 

Thus, the equation of the line we are trying to find is:
(y - 7) = 3(x - 2)
y - 7 = 3x - 6
y = 3x + 1

However, this is not an answer choice. The answers given have the constant on the right side of the equation. Thus, we will make our answer have the constant on the right side:
y - 3x = 1
-3x + y = 1
3x - y = -1

This is an answer choice. B, or 3x - y = -1 is the correct answer.

X=4y+2 in slope intercept form
siniylev [52]
Answer:
The slope intercept form is y=mx+c
So,
x=4y+2 should also be made in that form
x-2=4y
y=(x-2)/4
That’s the final answer in slope intercept form
