Refer to the image attached.
Given: 
and 
are congruent.
To Prove: 
ABC is an isosceles triangle.
Construction: Construct a perpendicular bisector from point B to Line segment AC.
Consider triangle ABD and BDC,
(given)
(By the definition of a perpendicular bisector)
(By the definition of a perpendicular bisector)
Therefore, 
by Angle Side Angle(ASA) Postulate.
Line segment AB is congruent to Line segment BC because corresponding parts of congruent triangles are congruent.(CPCTC)
Answer:
x = -1
Step-by-step explanation:
7(4x+1)−3x=5x−13
Distribute
28x +7 -3x = 5x -13
Combine like terms
25x+7 = 5x-13
Subtract 5x from each side
25x-5x +7 = -13
20x +7 = -13
Subtract 7 from each side
20x+7-7 = -13-7
20x = -20
Divide by 20
20x/20 = -20/20
x = -1
Answer:
n = 25
Step-by-step explanation:
Add to both sides.
n = 17 + 8 = 25
You'll have to adapt this problem statement to Brainly, as Brainly does not have the Segment Tool available.
"starts with 90 pencils" implies that the y-intercept is (0,90).
"gives away 15 pencils" implies a slope of -15 pencils per unit of time
Thus, the # of pencils Jabian still has is P(x) = 90 - (15 pencils / time unit)x
R=fixed rate
m=rate of miles
n= miless
T(n)=total amount per miles(n)
T (n) =mn+r
