-2x^2+8x+5 is the standard form
first function 2nd function
slope =(y2-y1)/(x2-x1) slope =(y2-y1)/(x2-x1)
=(14-2)/(3-0) m = (-3--12/(3-0)
12/3 m=(-3+12)/3
4 m =9/3 =3
y = 4x+2 y = 3x+-12
set these two equations equal
4x+2 = 3x-12
subtract 3x
x+2 = -12
subtract 2 from each side
x = -14
y = 3x-12
y =3*(-14)-12
y = -42-12
y = -54
ChoiceD
The answer would be (-1,-4) because -1 is the z factor and -4 is the why then solve to make them equal the same thing.
Wesley will need 10 10-inch stones, and 9 5-inch stones.
Since he wants to begin and end the pattern with 10-inch stones, we put a 10 at the beginning and end.
10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10
10 x 10-inch = 100 inches
9 x 5-inch = 45 inches
100 + 45 = 145 inches
Answer:
not 100% but I think it's Step 1
