On all of them? Which numbers?
Answer:
Proved CA=CB
Step-by-step explanation:
Given,
In ΔABC, CP is perpendicular to AB.
And CP bisects AB.
So, AP=PB and ∠CPA=∠CPB=90°
The figure of the triangle is in the attachment.
Now, In ΔACP and ΔBCP.
AP = PB(given)
∠CPA = ∠CPB = 90°(perpendicular)
CP = CP(common)
So, By Side-Angle-Side congruence property;
ΔACP ≅ ΔBCP
According to the property of congruence;
"If two triangles are congruent to each other then their corresponding sides are also equal."
Therefore, CA = CB (corresponding side of congruent triangle)
CA = CB Hence Proved
These are known as simultaneous equations,,
2x + y= -3 take this as 1st equation
x-2y=-4 take this as 2 nd equation
therefore x - 2y= -2 should be multiplied by 2 inorder to cut off 2x and 2x from the first and second equations.
by multiplying we get 2x - 4y = -4
therefore 3rd equation should be substracted from 1st equation...
now, 2x -4y - 2x -y = -4-(-3)
therefore, -2x and +2x is cut.
as a result -5y= -1
therefore y = 1 /5
then let us find x
2x + y = -3
::: 2x + 1/5= -3
therefore 2x= -3-1/5
finally, x= -16/5÷2
then x= 8/5
The first one, the y intercept is -3
Answer:
$860
