Step-by-step explanation:
<u>Point -slope form is:</u>
By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.
<u>How to find the slope?</u>
Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2
<u>Use the formula:</u>
<u>Example:</u>
- m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
Answer:
(7a-3a)+(2a-a)=16
4a+a or 1a =16
5a=16
5a/5=16/5
a =16/5 or a=3.2
Step-by-step explanation:
solving like terms or substract are same
you only have to find value of uknown value which was "a" question
Answer:
50
Step-by-step explanation:
Arc AT the center = angle at the center = 50
Answer:
50%
Step-by-step explanation:
First, find the difference between the two values
1.8-1.2=0.6
Then divide the original value by the difference
difference/original value
0.6/1.2=0.5
0.5*100=50
So, the amount of iron increased by 50%
Hope this helped! :)
