Answer:
Step-by-step explanation:
<u>Given equation of the line:</u>
<u>Use two points from the graph of the second line to find its equation:</u>
<u>Use double intercept form to find the equation:</u>
- x/a + y/b = 1
- x/ (-6) + y/(- 2) = 1
- 2x + 6y = - 12
Now we have the system, solve it by elimination.
<u>Multiply the first equation by 2 and the second equation by 3 and add up:</u>
- 2(- 3x - 9y) + 3(2x + 6y) = 2*18 + 3*(- 12)
- -6x - 18y + 6x + 18y = 36 - 36
- 0 = 0
All terms are cancelled, it means the equations are same, the lines overlap and there is infinite number of solutions.
Answer:
8km
Step-by-step explanation:
if he took 20km in 20min how about 1h
do cross multiplication( use 60min instead of 1h)1h = 60min
Answer:
B= 168
G=56
Step-by-step explanation:
3x+x= 224
4x=224
x=56
3x56=168
Well, let's see. First we would need to find how much money he earns each DAY. To find THAT, we would need to multiply 760 times 1.5, which would be $1,140. Now, in order to find out how many DAYS it will take to make $3,420, you would divide 3,420 divided by 1,140, which will be 3. So it will take 3 days to earn $3,420.
I hope I helped! =D
