Answer:
I think it would be 40?
Step-by-step explanation:
I think 40 because if I recall correctly, to find the range you must subtract the max from the min, the max being 100 and the min being 60 in this case.
Answer:
The simplified version of that equation would be .
Step-by-step explanation:
Since and have the same exponent and variable, we can combine them normally.
- =
Answer:
multiple each side by x - 1
2 = -4(x-1)
2 = -4x + 4
-2 = -4x
x = 1/2
If the line is perpendicular to y = 1/2x + 3, the slope will be the opposite sign of the reciprocal.
1/2 → opposite sign is (-) reciprocal is (2) → slope of ⊥ = -2
Now let's find the b → by substituting the values for y, m, and x in y = mx + b
1 = -2(9) + b
1 = -18 + b
19 = b
The equation is y = -2x + 19
or 2x + y = 19
