"planar notions": points in the same plane are coplanar intersecting lines with exactly one point in common.
Answer:
2x⁴ - 11x³ + 7x² + 5x - 3
Step-by-step explanation:
(2x²-3x+1) * (x²-4x-3) = 2x⁴ - 8x³ - 6x² - 3x³ + 12x² + 9x + x² - 4x -3
= 2x⁴ - 11x³ + 7x² + 5x - 3
Answer:
y=−2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6y+2(3y−5)=−34
6y+(2)(3y)+(2)(−5)=−34(Distribute)
6y+6y+−10=−34
(6y+6y)+(−10)=−34(Combine Like Terms)
12y+−10=−34
12y−10=−34
Step 2: Add 10 to both sides.
12y−10+10=−34+10
12y=−24
Step 3: Divide both sides by 12.
= 
y=−2
Answer:
b 5.2 *10-4
Step-by-step explanation:
.00052
We are moving the decimal 4 places to the right to make it in scientific notation. This puts it in the form a* 10^b a must be between 1 and less than 10 and b is the number of places we moved it. It we move it to the left it is positive and to the right it is negative.
5.2 *10-4
If the lines were parallel they would have the same slope. if the lines were perpendicular then the slope would be the negative reciprocal slope. The answer to your question would be -3/7.
