Answer:
n=-2
Step-by-step explanation:
1−(2n+9)=4(1−2)
1+−1(2n+9)=4(1−2)
1+−1(2n)+(−1)(9)=4(1−2)
1+−2n+−9=4(1−2)
1+−2n+−9=−4
(−2n)+(1+−9)=−4
−2n+−8=−4
−2n−8=−4
−2n−8+8=−4+8
−2n=4
Divide both sides by -2
-2n/2=4/-2
n=-2
15, if you plot the points, then seperate the x and y into two seperate lines, you can create a 3,4,5 triangle to find the distance between the points.

<em>Only y= x - 2 intercepts x-axis at 2 and y-axis at -2. Thus meaning that they intercept oppositely.</em>
<em>Find if both graphs are parallel, that means the equation must be false.</em>

<em>Multiply whole equation by 2 to get rid of the fractional 2.</em>

<em>Well, that doesn't seem to be parallel. This is called one solution answer. Both graphs intercept at (2,0). There are no linear graphs that intercept at (2,-2) except for y = x-2 so there are no graphs with (2,-2) that are parallel to the equation y = -5x/2+5 </em>
Answer:
C
Step-by-step explanation:
It usually works best to use the polynomial with fewer terms as the multiplier. A row of partial products is written for each term of the multiplier, so the fewer terms will result in fewer rows of partial products.
In order to keep like terms together, it is preferable to allocate a separate column of the multiplication tableau to each power of the operands or product. This means we want to make note of the fact that the cubic multiplicand has a coefficient of 0 for its x^2 term.
The best setup is the one shown in the attachment.
