We know that
<span>a) the slope-intercept form of the line---------------> y=mx+b
b) </span><span>if two lines are parallel both have the same slope
</span>then
<span>passes through the point (1,0) and is parallel to x-y=7
Step 1
Find the slope
</span>x-y=7------------> y=x-7------------> m=1
Step 2
Find the slope-intercept form of the line---> y=mx+b
point (1,0) m=1
0=(1)*(1)+b------> b=-1
y=(1)*x-1--------> y=x-1
the answer is
y=x-1
using a graph tool
see the attached figure
8*40 = 320 * 2 = $640 for the 2 workers
640/2000 = 0.32
labor cost is 32% of the revenue
For this case we must express the number "423" in a radical way.
We have to, we can rewrite it as:
So, we have to:
By definition of properties of powers and roots we have:
So:
Answer:
Answer:
x=3 and y=2
Step-by-step explanation:
(3X-Y=7)×4
x+4y=11
then
12x-4y=28
x+4y=11
now 13x=39
x=3
when you put on 1 equation you got y= 2
hopefully it works for you
