The y intercept in this graph is (0,1) ad the only equations that fit this are a and c.
To figure out whether it is a or c, find the slope. The line of the equation is going up, so he slope is positive. Equation c has the positive slope.
EQUATION C
Answer: r+7
Whatever his age is now, we add 7 to it. So we simply add 7 to r getting r+7.
Example: Say he is 10 years old now
r = 10
r+7 = 10+7 = 17
meaning he will be 17 seven years from now
Answer:
25.3
1_ draw a triangle
the shortest side is a which will be 8(bunnies)
diagonal will be c ( what you need to find )
the last side will be b.
so the equation is a2+b2=c2 ( 2=squared)
that means..... 8x8+24x24=c
8x8=64
24x24=576
then add
576+64=640
the find square root
√640=25.2982212813
simplify to 25.3
you know your answer is correct because c is always the biggest side
The student went wrong in step three. the solutions should have been -3 and 5
