Answer:
Option D that is y=-2(x+1) is the correct choice.
Explanation:
Given equation:
We have to find another equation which has only one solution.
Standard form of equation:
Condition for one solution.
We have to arrange other equation in the form of 
Mark all the options as a,b,c and d.
Now from the above options we can see that option 
are not providing the desired result.
So
can be obtained from the last option.
As
Option D that is 
is the equation from where we can obtained only one solution.
Answer:
Zeros Calculator. The zeros of a polynomial equation are the solutions of the function f(x) = 0. A value of x that makes the equation equal to 0 is termed as zeros. It can also be said as the roots of the polynomial equation. Find the zeros of an equation using this calculator.
Step-by-step explanation:
Please mark me the brainiest if I got it right
Answer:
Jackie runs for 
minutes and dances for 
minutes.
Step-by-step explanation:
Let the time she dances be 
and the time she runs for be 
minutes respectively.
Use the substitution method here ,
Therefore Jackie runs for minutes and dances for minutes.
Y = 3x - 4 . . . (1)
9x - 3y = 14 . .(2)
Putting (1) into (2) gives
9x - 3(3x - 4) = 14
9x - 9x + 12 = 14
12 = 14
Therefore, there is no solution.
