Answer:

It would be 4:15

Step-by-step explanation:

You would take 20 and 75 and put them in a ratio that would look like this 20:75, then they are divisable by 5 so you reduce them, when you reduce them you get 4:15

What is the slope of the line through the points (-2,-1) and (8,-3)?

RSB [31]

Answer:

- 1/5

Step-by-step explanation:

Slope of a line passing through two points can be calculated as:

$\text{slope}=\frac{\text{rise}}{\text{run}} \\\\ \text{slope}=\frac{\text{Difference of y coordinates}}{\text{Difference of x coordinates}}$

The given points are (-2, -1) and (8, -3). Using the values in above formula, we get:

$\text{slope}=\frac{-3-(-1)}{8-(-2)}\\\\ \text{slope}=\frac{-3+1}{8+2}\\\\ \text{slope}=\frac{-2}{10}\\\\ \text{slope}=\frac{-1}{5}$

Thus the slope of the line through the given points is -1/5. So 2nd option gives the correct answer

Doss [256]

Answer:

The initial value corresponds to the y value when x = 0

Step-by-step explanation:

Since the graph is given, it is unnecessary to "finish the line." It is only necessary to read the value of y from the graph where x=0.

What set of reflections and rotations would carry rectangle ABCD onto itself? Parallelogram formed by ordered pairs A at negativ

pickupchik [31]

Each of the 4 choices has been drawn step by step as follows:

the first transformation is drawn in light grey
the second transformation is drawn in dark grey
the third transformation is described as how it should be.

Choice I, picture I:
Rotate 180°, reflect over the x-axis, reflect over the line y=x

the last transformation should be : reflect with respect to the y-axis

Choice II, picture II:
Reflect over the x-axis, rotate 180°, reflect over the x-axis

the last transformation should be : reflect with respect to the y-axis

Choice III, picture III:
Rotate 180°, reflect over the y-axis, reflect over the line y=x

the last transformation should be : reflect with respect to the x-axis

Choice IV, picture IV:
Reflect over the y-axis, reflect over the x-axis, rotate 180°

the last transformation should be : rotate 180° CORRECT!

Answer: Reflect over the y-axis, reflect over the x-axis, rotate 180°
