Answer: -2, -1
Step-by-step explanation:
It's where they intersect
Answer:
it has no solution
Step-by-step explanation:
first of all if we want to know that how many solutions does it the system we can know easly
- if a1/a2=b1/b2=c1/c2 then the system has infinite solution
- if a1/a2=b1/b2≠c1/c2 the system has no solution
- if a1/a2≠b1/b2 the system has no solution
so in this system a1=2,a2=4,b1=3,b2=6,c1=4&c2=4
so 2/4_3/6_4/4=(to becomfortable to compare we have to find the denominators LCM.LCM(4,6)=12
6/12=6/12≠12/12.
so the system has no solution.
&you can also solve by this way
2x+3y=4 (multiply by ‒2 to be y=0)
4x+6y=4
‒4x‒6y=‒8
4x+6y=4
= 0+0=‒4(error)
so it has no solution
i think it is clear & i hope it helps you.
Answer:
q=8/5 r
Step-by-step explanation:
Step 1: add -3q to both sides
-7q+12r+-3q=3q-4r+-33
-10q+12r=4r
Step 2: Add -12r to both sides
-10q+12r+-12r=-4r+-12r
-10q=-16r
Step 3: Divide both sides by -10.
-10q/-10=-16r/-10
q=8/5r
The area of the circle formula --> 
≈ 3.14
- r: length of radius --> 7km
<em>Length of radius is half of diameter which is 14km long</em>

Hope that helps!
140 is ur answer…
Im not really sure but I think this is it
Really hope this helps
