Answer:
-2x²-2x+8
Step-by-step explanation:
To find the reciprocal of a mixed number, we first convert it to an improper fraction. 1 1/5 = 5/5 + 1/5 (remember that 1 whole would have the same numerator and denominator) = 6/5.
The reciprocal is this number flipped, so 5/6.
To find the sum of 1.25 and -1 3/4, we will convert the decimal to a fraction. 0.25 is read as "twenty-five hundredths," so the fraction would be 25/100. This will simplify to 1/4, so 1.25 = 1 1/4.
1 1/4 + -1 3/4 = -2/4 = -1/2.
Now we add 5/6 + -1/2:
Find the least common denominator (LCD). 6 is the first number that both 6 and 2 will divide into evenly. This gives us 5/6 + -3/6 (we multiply 2 by 3 to get 6, so we multiply the numerator, -1, by 3 as well). This equals 2/6 which simplifies to 1/3.

Answer:
y(x) = -2x -8
Step-by-step explanation:
using the hint, insert the points (x,y) in the equation:
-2 = -3m + b eq1
2 = -5m + b eq2
eq2 - eq1 :
4 = -2m ==> m = -2
insert m in eq1:
-2 = -3*(-2) +b ==> b = -8
I think the answer is: 1/50
