Answer:
an = -9 -3(n -1)
Step-by-step explanation:
The explicit formula for an arithmetic sequence with first term a1 and common difference d is ...
an = a1 +d(n -1)
Putting your numbers into the formula gives ....
an = -9 -3(n-1)
Answer:
the system has no solutions
Step-by-step explanation:
the systems are shaded in different directions with no part of them intersecting
this means that there are no solutions
Answer:
10 units²
Step-by-step explanation:
Convert to slope intercept form (y=mx+b).
2x-4y=8
subtract 2x from each side
2x-2x-4y=-2x+8
-4y = -2x+8
divide by -4
y = -2/-4 x +8/-4
y = 1/2 x -2
it is now in slope intercept form
