40 points to whoever can answer for me!
luda_lava [24]

Answer:

x≤-3      2 ≤x<7  

Step-by-step explanation:

(x^2+x-6) /(x-7) ≤0

Factor the numerator

(x+3)(x-2) / (x-7)≤0

Critical points are

X =-3  X =2  X=7

We need to check the values when

x≤3  -3 ≤ x≤2           2 ≤x<7   x>7  

(x cannot be 7 because then the denominator is zero)

and see when it is less than 0

Substitute a value in and see if factor is positive or negative

x≤-3

(negative)(negative) / (negative) =   negative

-3 ≤x≤2    

(positive)(negative) / (negative) = positive  this range does not work

      2 ≤x<7  

(positive)(positive) / (negative) = negative

x>7

(positive)(positive) / (positive)

The scatter plot shows the time spent watching TV, x, and the time spent doing homework, y, by each of 23 students last week.
malfutka [58]

Answer:

(a)\ y = -0.75x + 26

(b)\ y = 14.75

Step-by-step explanation:

Given

See attachment for scatter plot

Required

Equation of the line of best fit

Pick any two points on the line

(x_1,y_1) = (24,8)

(x_2,y_2) = (8,20)

Calculate the slope (m)

m =\frac{y_2 -y_1}{x_2 -x_1}

m =\frac{20-8}{8-24}

m =\frac{12}{-16}

m =-0.75

The equation is then calculated using:

y = m(x - x_1) + y_1

So, we have:

y = -0.75(x - 24) + 8

y = -0.75x + 18 + 8

y = -0.75x + 26

Solving (b): y, when x = 15

y = -0.75x + 26 becomes

y = -0.75*15 + 26

y = -11.25 + 26

y = 14.75
