I am pretty sure 52 degrees
A) 27, 81
b) -30,-15
c) -3, 1
d) -320, 1280
Y= 2.50 + 1.95( x)
27.46 = 2.50 + 1.95(x)
+2.50 -2.50
29.96 = 1.95(x)
/ 1.95 / 1 .95
x = 15.4 Miles total
we solve the second system: (it is more easy).
8x+9y=48
-8.5y=-51 ⇒y=-51/-8.5=6
8x+9(6)=48
8x+54=48
8x+54-54=48-54
8x=-6
x=-6/8=-3/4
Then; in te second system the solution is : x=-3/4; y =6
Now, we replace "x" by "-3/4" and "y" by "6", in the first systmen.
8x+9y=48
8(-3/4)+9(6)=-6+54=48. verified
12x+5y=21
12(-3/4)+5(6)=-9+30=21 verified
Therefore,
These two wystems are similar.
Answer:
Inverse of F does not exist
Step-by-step explanation:
2 different x values lead to 1 y value therefore it cannot be reversed
