Answer:
yes
Step-by-step explanation:
its a straight line
Step-by-step explanation:
2.5x+12=32
We move all terms to the left:
2.5x+12-(32)=0
We add all the numbers together, and all the variables
2.5x-20=0
We move all terms containing x to the left, all other terms to the right
2.5x=20
x=20/2.5
x=8
Answer:
-48
Step-by-step explanation:
36/-3 = -12
-12 + 2(27/3 * -2)
27/3 = 9
-12 + 2(9 * -2)
9 * -2 = -18
-12 + 2(-18)
2 * -18 = -36
-12 + -36 = -12 - 36
-48
Answer:
2kx+4y=20 ⇒ kx+2y=10
3x+6y=30 ⇒ x+2y= 10
k is the coefficient of x, so it is the slope of the line
- when k=1, both equations will be same, then there are many solutions
- when k=0 there is one solution
- when k is anything different, then the lines will be parallel, so no solutions
