Well to isolate the variable you should subtract 6 from both sides resulting in -4y > 16
Now just divide by -4, however, keep in mind that when you divide or multiply by a negative number when there is a sign, always switch the sign, so just divide by -4 and get y < 4

Find all real numbers z for which the equation (z-5)x^2-zx+5=0 only has one real solution. Please help!! I am giving Brainliest!
frutty [35]

Answer:

z = 5

x = 0

x = 1

Step-by-step explanation:

(z - 5)x^2 - (z - 5)x = 0          Take out z - 5 as a common factor

(z - 5)(x^2 - x)                        Take out x as a common factor

(z - 5)(x)(x - 1)                          Any one of these could equal 0. There are 3 solutons.

z - 5 = 0                                  Add 5 to both sides

z - 5 + 5 = 0 + 5

z = 5

===============

x = 0

===============

x - 1 = 0

x - 1 + 1 = 0 + 1    

x = 1

==============

What are the y-intercept and the slope of the line represented in the graph?
Artist 52 [7]

the correct answer is B. y-intercept = 4 and slope = -2

the y intercept is just where the line crosses the y axis and you can clearly see that happens at +4

The slope = Rise/run which in this case = -2
