Answer:
y=4x-8
Step-by-step explanation:
Slope= y1-y2/x1-x2
Slope = 4- (-16)/3-(-2)=4+16/3+2=20/5=4
Equation: y=4x+b
Let y=4 and x=3
4=12+b
b= -12+4
b=-8
Therefore: y=4x-8
Step-by-step explanation:
First of all, we need to Reduce or Simplify the fractions to do this problem.
18/56 simplified is 9/28.
12/56 simplified is 3/14.
So our equation now is 9/24 divided by 3/14. (You do not need common denominators for dividing fractions.)
To find the answer of this problem, we follow a formula, Keep, Change, Flip.
You keep it the same.
Change the division sign to multiplication sign.
Then Flip the second fraction's numerator and denominator.
For example: 3/8, flipped is 8/3.
For example: 14/6, flipped is 6/14.
So we keep the problem the same:
9/28 / 3/14.
Change the division sign to multiplication sign:
9/28 x 3/14.
Then Flip the second fraction:
9/28 x 14/3 = ?
9 x 14 = 126,
28 x 3 =84.
Our answer is 126/84.
We should reduce our answer to get the proper results.
Reduced is:
3/2
Our final answer is 3/2.
Good luck on testing!
Answer:
number of students who like only iphone is 36...
Step-by-step explanation:
100 is the total number..
from that 40 like both so we subtract..
100-40=60..
60 = 2x + 3x..
60 / 5 = 12..
so numbet who like iphone is 3x which is 3 * 12=36..
Answer: y= 1/8x - 1

Answer:
115°
Step-by-step explanation:
● DAG is equal to 180°
● DAG = DAH + HAG
● HAG IS 130°
● DAG = DAH + 130° => DAH + 130° = 180°
● DAH = 180° - 130° = 50 °
■■■■■■■■■■■■■■■■■■■■■■■■■■
ADH is a triangle
● ADH + DHA + HAD = 180°
● ADH + DHA + 50° = 180°
DHA shares the same vertex with CHE. They are opposite angles so they have the same size (35°)
● ADH + 35° + 50° = 180°
● ADH + 85° = 180°
● ADH = 180° - 85°
● ADH = 95°
■■■■■■■■■■■■■■■■■■■■■■■■■■
BDA equals 180°
● BDA = 180°
● BDH + ADH = 180°
● BDH + 95° = 180°
● BDH = 180° -95°
● BDH = 85°
■■■■■■■■■■■■■■■■■■■■■■■■■■
BDE is a traingle
● BDH+ DEB + EBD = 180°
● 85° + DEB + 30° = 180°
● DEB + 115° = 180°
● DEB = 180° - 115°
● DEB = 65°
■■■■■■■■■■■■■■■■■■■■■■■■■■
CEF equals 180°
● CEF = 180°
● DEB + x° = 180°
● 65° + x° = 180°
● x° = 180° - 65°
● x° = 115°
