Answer:
make a graphical representation for our case do we have infinite lines pass through a point M?
Step-by-step explanation:
If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
Answer:
Step-by-step explanation:
First distribute. -2•x and -2•3
This will give you y-4=-2x+-6
(You could also write it y-4=-2x-6)
Then add 4 to both sides.
y=-2x-2
Sample Response: The object will hit the ground after 5 seconds. You can rewrite the quadratic function as a quadratic equation set equal to zero to find the zeros of the function 0 = –16t2 + 80t + 0. You can factor or use the quadratic formula to get t = 0 and t = 5. Therefore, it is on the ground at t = 0 (time of launch) and then hits the ground at t = 5 seconds

I Rewrite the quadratic function as a quadratic equation set equal to zero: 0 = –16t2 + 80t + 0.
Use the quadratic formula to solve for the zeros.
Factor to solve for the zeros.
t = 0 and t = 5 seconds.
The object will hit the ground after 5 seconds.
Answer:
Let , the constant factor be x so 3 X + 5 x + 7 x = 180
Step-by-step explanation:
Find out the value of x
7x+3x+5x=180
15x=180
x=180/15
x=12
now,
x=3 multiplied by 12=36
x=7 multiplied by 12=84
x=5 multiplied by 12=60
brainliest pls if u wannna
The answer is A. 50
2x + 40 = 140
2x = 140 - 40
2x = 100
x = (100 / 2 )
x = 50
