it does not pass through quadrant I.

Both the slope and Y value are negative.

Meaning this equation goes up to the left and down right.

(you can use a graphing calculator (if you have one.) and plug this equation into the GRAPH.) It will show you the line.

It doesn't passes because:

1) It has a negative gradient
2) It has a y-intercept of -5

Which equation has a constant of proportionality equal to 1? A. y=10/11x B. y= 7/8x C. y= 3/15x D. y=x

shtirl [24]

An equation is said to have a constant of proportionality if 'x' is a multiple of 'y' or 'y' is a multiple of 'x'.

Now, we have to determine an equation with constant of proportionality as '1'.

1. $y = \frac{10}{11}x$

This equation has constant of proportionality as ' $\frac{10}{11}$ '.

2. $y = \frac{7}{8}x$

This equation has constant of proportionality as ' $\frac{7}{8}$ '.

3. $y = \frac{3}{15}x$

This equation has constant of proportionality as ' $\frac{3}{15}$ '.

4. $y = x$

This equation has constant of proportionality as '1'.

Option D is the correct answer.

The graph of g(x) is the graph of f(x)=5x+15 compressed horizontally by a factor of 1/5 .

Vlad [161]

Consider the value of f at x=2.

f(2)=5*2+15=10+15=25. Thus, we have the point (2, 25) in the graph of f.

The graph of g is the graph of f compressed horizontally by a factor of 1/5.

So at 2, the y-coordinate is 25(1/5=5). That is, we have the point (2, 5).

All pairs (x, y) in f can be described by (x, 5x+15), thus, all pairs (x, y) in g can be described by (x, (5x+15)/5), that is (x, x+3). Thus, the rule for g is :

g(x)=x+3.

Answer: <span>A) g(x)=x+3</span>

Step-by-step explanation:

The given data : 4, 4, 4, 4, 6, 8

Number of data values : n= 6

The mean value of the given data will be :-

$\overline{x}=\dfrac{\sum_{i=1}^{6}x_i}{n}\\\\\Rightarrow\ \overline{x}=\dfrac{30}{6}=5$
