Answer:
10x^4-15x^3+17x^2-13x+17
Step-by-step explanation:
P-2Q
Replace P and Q with the given values,
4x^4-3x^3+x^2-5x+11-(2(-3x^4+6x^3-8x^2+4x-3)
4x^4-3x^3+x^2-5x+11-(-6x^4+12x^3-16x^2+8x-6)
4x^4-3x^3+x^2-5x+11+6x^4-12x^3+16x^2-8x+6
10x^4-15x^3+17x^2-13x+17
Answer: 2x + 40 = 150
Step-by-step explanation:
Jane has 150 feet of fencing. 40 feet will go for the portion opposite the house, The remaining fencing will go for the two sides of equal length x. That makes 2x for both. So:
<u>2x + 40 = 150</u>
[x = 55 feet]
ANSWER
D. Ellipse;
EXPLANATION
The given equation is
Dividing through by 9 gives
This is the equation of an ellipse centered at the origin.
If this ellipse has been translated, so that its center is now at (-1,3), then the equation of the translated ellipse becomes
We multiply through by 9 to get,
Expand to obtain;
Expand to obtain;
Regroup and equate to zero to obtain;
The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20
I reccomend that you add an image or better explain what you want us to do.
