Answer:
The last graph.
Step-by-step explanation:
The first thing we look for is the y-intercept at -2. The only graphs where the line passes through the y-intercept at this point are the first and the last.
The slope of the line we want is -2/3. This means the line decreases; the first graph increases, not decreases, so it must be the fourth one..
Checking the fourth graph, from the y-intercept, we go down 2 and over 3 to find the next point; this means the slope is -2/3 and this is the correct line.
W = 20
<span>l = 2w = 40 </span>
<span>if l is increased by x, w is increased by 1/2x </span>
<span>A = l x w = (40 + x)(20 + 1/2x) = 1/2(40 + x)(40 + x) </span>
<span>A = (40+x)²/2</span>
Answer:
e
Step-by-step explanation:
5+3n=21-n////5=21+2n////-16=2n////-8=n, but you need to find the absolute value, so yo get n=8
