Answer:

40 girls

Step By Step Explanation:

assume boys = y girls = x

y = 1/2x + 10

y = 30

30 = 1/2x + 10

1/2x = 20  

x = 20 *2 = 40

girls is  40   boys is 30

The scatterplot shows the number of minutes spent reading (x) and the number of pages read (y) by each of seven students last ni
Andreyy89
Though you did not post the scatter plot, I was able to figure out the scatter plot.

From the scatter plot, the labelled points are (32, 23) and (43, 30).

The equation of a line passiong through the points (32, 23) and (43, 30) is given by:

\frac{y-y_1}{x-x_1} = \frac{y_2-y_1}{x_2-x_1}  \\  \\ \Rightarrow \frac{y-23}{x-32} = \frac{30-23}{43-32} = \frac{7}{11}  \\  \\ \Rightarrow y-23= \frac{7}{11} (x-32)= \frac{7}{11} x- \frac{224}{11}  \\  \\ \Rightarrow y=\frac{7}{11} x- \frac{224}{11}+23=\frac{7}{11} x+ \frac{29}{11}

Therefore, the equation that represents the linear model is

y=\frac{7}{11} x+ \frac{29}{11}

X+3y=9. graph using slope and y-intercept
timama [110]
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-intercept
I
in order to do that, you must change this equation.

x+3y=9

-x     -x
----------
3y=9-x

Then, rewrite it as: 

3y=-x+9
_______
3      3

simplify to  

y=-x/3 +9

Find the equation of the line shown.
Ymorist [56]

Answer:

y= -2x+9

Step-by-step explanation:

The equation will be written this way :

y= m*x+c

  • m is the slope
  • c is a constant
  • m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
  • y = -2x+c
  • replace x and y by the coordinates of a point to get c
  • 1= -2*4+c
  • c = 9

y = -2x+9
