Write the equation of the line that passes through (-1, 3) and is parallel to the line y = -x + 1.

ra1l [238]

Answer:

Step-by-step explanation:

y = -x + 1......same as y = -1x + 1.....in y = mx + b form, ur slope is in the m position....so the slope of this line is -1.

a parallel line will have the same slope.

(-1,3)...x = -1 and y = 3

slope(m) = -1

y = mx + b.....we have x,y, and m....now we need to find y int (b)

3 = -1(-1) + b

3 = 1 + b

3 - 1 = b

2 = b

so ur parallel equation is : y = -1x + 2...or just y = -x + 2

The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the numbe

FromTheMoon [43]

Answer:

Internal angle = $160^\circ$

Number of sides = 18

Step-by-step explanation:

Given that:

We have a regular polygon with number of sides unknown.

Measure of an exterior angle of the polygon = $20^\circ$

To find:

Measure of an interior angle and the number of sides of the polygon?

Solution:

Let us have a look at the relation of sum of external angles.

Sum of one internal angle and its corresponding external angle = $180^\circ$

Internal angle + external angle = $180^\circ$

Internal angle = $180^\circ$ - $20^\circ$ = $160^\circ$

Sum of all the external of a regular polygon = $360^\circ$

All the external angles will be equal because it is a regular polygon.

Let the number of sides = $n$

Therefore,

$n \times 20^\circ = 360^\circ\\\Rightarrow n = 18$

Therefore, the answers are:

Internal angle = $160^\circ$

Number of sides = 18

Products of two numbers 32.40 in that one number is 15.00 find the other number

Nataly_w [17]

Do inverse operation. Divide 15.00 from 32.40. You will get the answer of 2.16. That is the other factor. To check, just multiply 15.00 and 2.16. Your answer will be 32.40.
