Answer:
0 solutions
Step-by-step explanation:
-6x+3y=18
y=2x-2. so substitute y in the first equation
-6x+3(2x-2)=18 distribute and combine like terms
-6x +6x-6=18 and we end up with
-6=18 witch is never true so the system of equation has 0 solutions
Steps:
y2-y1/x2-x1
(7-3)/(5-3)= 4/2=2
[2 is the slope]
Now to find the the y-intercept
-take a random point I chose (3,3)
3=2(3)+c
3=6+c
3-6=c
-3=c
y-intercept is -3
Substitute and the answer is:
y=2x-3

<u><em>Answer: -2/5+1/5i</em></u>
Explanation:
complex rule.
(-3*7+1*1)+(1*7-(-3)*1)i/7²+1² ← as the fractions
then refine and rewrite the problem down.
-20+10i/50 ← as the fractions shown.
-20+10i/50=-2+i/5
you can also rewrite the problem down in standard complex form.
-2+i/5=-2/5+1/5i
<u><em>=-2/5+1/5i</em></u>
Hope this helps!
Thanks!
Have a great day!
Let say
e=number of english teachers
m=number of math teachers
3 more english tahn math
e=m+3
ratio if e to m is 6:5
e:m=6:5
e/m=6/5
e=m+3
(m+3)/m=6/5
times 5m both sides
5(m+3)=6m
5m+15=6m
minus 5m both sides
15=m
e=m+3
e=15+3
e=18
