I cant really show you how to graph this but i can try to explain it. you would make a 4 quadrant graph and do rise over run.
1)start by making the graph
2) on the line of the graph marked Y is where you would put -4
3) From -4, you would go up (rise) by 2 and go over to the right 1 where you end is the slop
Answer:
42.25
Step-by-step explanation:
65*35%=22.75
65-22.75=42.25
Answer:
0.84
If you're looking for a percentage it'd be 84%
Step-by-step explanation:
The number of hours that it'll take both printers to do the job is 2.4 hours.
<em>Number of hours used by printer A = 6 hours</em>
<em>Number of hours used by printer B = 4 hours </em>
<em />
Therefore, the number of hours that'll be used by both printers will be calculated thus:
1/6x + 1/4x = 1
Using 12 as the LCM
2x + 3x = 12
5x = 12
Divide both side by 5
5x/5 = 12/5
x = 2.4 hours

Answer:
220
Step-by-step explanation:
Now, I'm not sure if 220 is correct, but I'll explain my reasoning.
We know three angles of a triangle add up to 180 degrees.
So, the smaller triangle has 70 degrees and <em>a</em><em> </em>and <em>b</em><em> </em>variables. By virtue, <em>a</em><em> </em>+ <em>b</em><em> </em>+ 70 = 180.
So, <em>a</em><em> </em><em>+</em> <em>b</em><em> </em>= 110.
Likewise, when you look at the whole triangle, 70 degrees is also one of the angles while <em>c</em><em> </em>and <em>d</em><em> </em>are unknown.
So, <em>c</em><em> </em>+ <em>d</em> + 70 = 180.
This means <em>c</em><em> </em>+ <em>d</em><em> </em>= 110.
So, <em>(</em><em>a</em><em> </em>+<em> </em><em>b</em><em> </em>) +<em> </em><em>(</em><em>c</em><em> </em>+<em> </em><em>d</em><em> </em><em>)</em><em> </em><em>=</em><em> </em>
110 + 110 =
220 degrees.
I hope this helps!
