Answer:
(-3,-43) and (3,107)
Step-by-step explanation:
input 25x+32 for y
25x+32=5x²+25x-13
32=5x²-13
-5x²=-45
x²=9
x=+-3
which means you separate the solution
x= -3
x= 3
then input the answers you got for x, in both equations. Then you'll get your y.
y=25(-3)+32
-43
Then check your answer.
Then input the other answer you got for x.
I may be wrong, but I tried and checked my answers.
Answer:
1100 and 300
Step-by-step explanation:
Step-by-step explanation:
area of equilateral ∆ =

here a = 3
area of ∆ = 3.9 in^2
area of circle

= 19.63 in^2
area of shared region = 19.63-3.9= 15.73 in^2
180-65=115°
that's the answer
When you reflect FGH across the y-axis, you are left with the vertices of F'G'H at (2, -1) (-2, 2) (-4, -3)
The correct answer is b.
Hope this helps =)
