When 5 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.
wariber [46]

Answer:

-1

Step-by-step explanation:

You can write it as...

x^{2} -5=4x

Carry the 4x

x^{2} -4x-5=0

Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have

(4-\sqrt{16+20}) /2=\frac{4-6}{2}=\frac{-2}{2} =-1

Therefore our answer is -1

Y = 5-3x, Darw the graph of the function. Use the find the value of y when x=4, and when x = 5​
stellarik [79]

Answer:

The line passes through (4, -7) and (5, -10).

Step-by-step explanation:

When x = 4, y = 5 - 3(4), or 5 - 12, or -7.  Thus the point (4, -7) lies on the graph.  Similarly y = 5 - 3(5) = -10 when x  = 5.  Thus, the line also goes through (5, -10).  Plot these two points and draw a line through them.  Doing this will result in the desired graph.
