ANSWER:

y = x - 4.

Plugging the respective value,

6 = 10 - 4

16 = 20 - 4

26 = 30 - 4

36 = 40 - 4

Hence, verified.

Gwar [14]

Answer:

(a) x > 4   (b) y < -2

Step-by-step explanation:

Domain is referring to the x-values while the range is referring to the y-values.

Since the function (the line) has a circle at the point (4, -2), the function will be exclusive at that coordinate.

The line goes to infinity for the x-values from 4, so you write x > 4 or ∞ > x > 4.

Similarly, the line goes to infinity for the y-values from -2, so you write y < -2 or -∞ < y < -2.

May someone please help me with this question
Cloud [144]

Answer:

2+i or 2-i (D)

Step-by-step explanation:

First you use the quadratic formula.  X= (-b +/- \sqrt{b^{2}-4ac })/2a

a=1

b=-4

c=5

X= (4 +/- \sqrt{16-20})/2

X=(4 +/- \sqrt{-4})/2

The square root of -4 is 2i.  i=√-1.  Therefore 2i= 2√-1 .If you simplify that, it becomes  √-4i.  

X= (4+/- 2i)/2

X= 2+/-i

X= 2+i or 2-i

what equation would represent the same linear relationship for the points (40,80) (80,115) (120,140) (160,165)
tiny-mole [99]
You can use the formula y1-y2=m(x1-x2)

to find m, you just do (y2-y1)/(x2-x1) so....

(115-80)/(80-40)= 35/40= 7/8

then plug it into the point slope equation:

y-115=7/8(x-80)

y-115=7/8x-70
y= 7/8 x + 45

Is the z score corresponding to a number or score below the mean always negative?
rusak2 [61]

Answer:

Yes

Step-by-step explanation:

The z-score corresponding to a number or score can be calculated using:

z =  \frac{x -  \mu}{ \sigma}

Where x stands for the individual scores, and

\mu

stands for the mean.

Since

x \:  \:  <  \:  \mu

for all numbers or scores below the mean, the difference will always be negative these values below the mean.

This will always result in a negative z-score for all numbers below the mean.
