Why cant you ask your teacher thats what they are for
I being the intercenter of the triangle means that IA = BI= CI
CI = 52-2X
AI = 3X +7 ==> AI = IC ==> 3X+7 = 52-2X SOLVE FOR X
3X+2X = 52-7 ==> 5X = 45 & X =9
IF X = 9 THEN IC = 52-2(9) = 34. IC =34
Answer:
Step-by-step explanation:
First, we will eliminate the x, so we multiply the first one by 2.
4x+6y=4
4x-2y=4
So, we have y=0, and we put that in the equations, so x is 1
Answer:
yes
Step-by-step explanation:
y <= -4x + 12
(2,4) 4 <= -4*2 + 12 4<= 4 is true
Positive infinity and negative infinity
