In order to solve this problem, We need to substitute the first four numbers (1,2,3,4) for n. After this we calculate:
First item:
a1= -2*1 + 4=-2+4=2
Second item:
a2= -2*2 + 4 =-4+4=0
Third item:
a3= -2*3 + 4 =-6+4=-2
Forth item:
a4= -2*4 + 4 =-8+4=-4

So the first 4 items are: 2,0,-2,-4..

Answer:

D. Graph D

Step-by-step explanation:

The "y <" tells you two things: (1) shading will be below the line, where y-values are less than those on the line, and (2) the line will be dashed, because the "equal to" case is not included.

Only one graph has a dashed line with shading below: Graph D.

6. Given that ABCD is a quadrilateral with A(-2,-2), B(1, 1),

Answer:

it is a parallelogram

Step-by-step explanation:

so first plot out points and then you find the slope for each of the corresponding lines.

First lets find the slope for AB. you must subtract them and make it -2-1/-2-1. it ends up having a slope of 1.

Then find the slope of the corresponding side(CD). this we will subtract -2-1/3-6. this will have a slope of 1 and will be parallel to AB.

Next you find the slopes of the other two sides starting with AC. we will subtract -2-(-2)/-2-3. this will be a vertical line which means it has a slope of 0.

finally the last step is you see if BD has an equal slope to AC. you then subtract 1-1/1-6. this is also a vertical line so the slope is 0 just like AC so they are both parallel.

in conclusion there are two sets of parallel lines so you have a parallelogram
