Answer:
rational
Step-by-step explanation:
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
Percentage of trumpet =16/64×100
=100/4
: =25%
The easiest way to to this it to make 75% a decimal. To do that you have to divide by 100 making it .75. After you have .75 just multiply it to 18 and you get...13.5
