-11
Step-by-step explanation:
<u><em>Answer:</em></u>
The slope of the line that passes through (-1, -7) and (3, 5) is 3
<u><em>Explanation:</em></u>
<u>The slope of the line is calculated using the following rule:</u>
<u>We are given the following points:</u>
(3 , 5) representing (x₁ , y₁)
(-1 , -7) representing (x₂ , y₂)
To get the slope, we will simply substitute with the givens in the above equation
<u>This is done as follows:</u>
You haven't attached the table for the second part. However, follow the same procedure. Pick two points from the table, substitute with them in the above equation and you'll get the slope
Hope this helps :)
Answer:
The significant figure of the result is 138.8
Step-by-step explanation:
24.78*(37.3 - 31.72)
Solving the bracket first:
37.3 - 31.72 = 5.58
A zero is added to 37.3 before the substraction, so;
37.3 - 31.72 = 37.30 - 31.72 = 5.58
Following the rule of significant figure; we have the answer of the substraction as 5.6 since the least number of significant is one decimal place.
The new expression will be:
24.78 * 5.6 = 138.768
Therefore, the result of our expression 138.8 by following the rule of significant figure
Answer:
Step-by-step explanation:
A and B are along a straight line
(3x - 20) + 2x = 180
5x = 200
x = 40
3(40) - 20 = 100°
Answer:
360°
Step-by-step explanation:
The exteriors angles of a pentagon are (m + 5)°, (2m + 3)°, (3m + 2)°, (4m + 1)° and (5m + 4)° respectively. Find the measure of each angle. Hints: The sum of all exterior angles of a polygon is 360°.
