Answer:
Step-by-step explanation:
To solve this we should use the Euclidean division :
- Our polynomial function is 16-2x³-6x²+x+9=-2x³-6x²+x+9
- we should divided by : 4+3x-2=3x+2 and see the rest
Here is a picture with the operation
- the rest is 47/9 so the number I SHOULD SUBSTACT IS 47/9
Answer:
y=-x+
Step-by-step explanation:
First, calculate the slope of the line that is perpendicular to the equation of line we are asked to find
m=(y2-y1)/(x2-x1)
=(2-(-4))/(-2-1)
=6/-3
=-2
in this equation the slope is 2, and to find the first equation, use y=mx+b
use the point (1, -4) to find b
-4=(2)(1)+b
-4=2+b
b=-6
the first equation of the line is y=2x-6
to find the x intercept of that line substitute 0 for y
0=2x-6
2x=6
x=3
the slope of a line perpendicular to this would be the opposite reciprocal of the slope which would be equal to -1/2
for the second equation of the line to pass thorugh the x-intercept of the first line, it must pass through (3, 0), so substitute and solve for b
y=mx+b
0=(-1/2)(3)+b
b=3/2
thus the equation of the line that is perpendicular to the line through (1,-4) and (-2, 2) and passes through the x intercept of that line is y=-x+3/2
That's the diagram..
(12×3) + 3(0.67×7) = 50.07inches²
≈ 50inches²
