Answer:
9/10, 80, and 16
Step-by-step explanation:
If 0.9 is what it was (can't read it lol) then that's like 9/10
And just multiply 16 by 5 is 80 so it's 20% of 80
And the last one is 16$
Answer:
42.5
Step-by-step explanation:
x 15
_ _
85 100
15x85=1275
1275/100=127.5
127.5-85=42.5
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
