ANSWER:

The 1st one: -3x + y = 5

ABOUT STANDARD FORM:

Ax + By = C
A & B & C are integers
A & B are both non - zero
This form is good to use when wanting to find the x & y intercepts of a line

y - 2 = 3(x + 1) --- IN POINT SLOPE FORM

y - 2 = 3x + 3

+ 2 + 2

y = 3x + 5 --- IN SLOPE INTERCEPT FORM

-3x -3x

-3x + y = 5 --- STANDARD FORM

Hope this helps you!!! :)

Select the two figures that are similar to the 5 by 10 figure that is shown.

Lapatulllka [165]

Answer:

Figure (i) and (iv)

Step-by-step explanation:

Given:

Optional figure is given in attached file.

We need to find two figures that are similar to the 5 by 10 figure.

All the given figure are $m\times n$ form.

Where m represent the number of rows and n represent the number of columns.

Solution:

Observe that in the given figure 5 by 10, the number of rows is 5 and number of columns is 10, that is, the number of columns is double of that the number of rows.

So we need to find two such figures whose number of columns is double of the number of rows.

From the given figures, figure (i) the number of rows is 2 and number of columns is 4, which is double of number of rows. so it is similar to 5 by 10 figure.

Similarly in figure (iv), the number of rows is 4 and number of columns is 8. so the number of columns is double the number of rows, so it is similar to the figure 5 by 10.

Therefore, the two figures that are similar to 5 by 10 figure are given in attached file such as (i) and (iv).
