Answer:
f(x) = (x - 10) (x + 10)
Step-by-step explanation:
The equation looks like the difference of squares so 5 and 20 are out
-10 x -10 = 100
-10 x 10 = - 100
so (x - 10) (x + 10)
69.78+26.73-100 just use your calculator and you will out and that a hint
Answer:
y = -3/4x + 11/2
Step-by-step explanation:
y2 - y1 / x2 - x1
1 - 4 / 6 - 2
-3 / 4
-3/4
y = -3/4x + b
4 = -3/4(2) + b
4 = -3/2 + b
11/2 = b
