Answer:
-21 is the correct answer
Step-by-step explanation:
-7.5 - 5 - 8.5 = -21
The only 5-digit numbers that do the job are 21,143 and 28,847 .
So, either
a = 1 and
b = 3
or
a = 8 and
b = 7 .
The sum of the values that 'a' can have is (1 + 7) = <em>8</em> .

Answer:
The perpendicular line would be y = -3x - 7
Step-by-step explanation:
To find the equation of the line, we first need to solve the original line for y.
-x + 3y = 9
3y = x + 9
y = 1/3x + 3
Now we know the slope of the original line to be 1/3. Since perpendicular lines have opposite and reciprocal slope, we know the new line to have a slope of -3. We can then use that along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
