Answer:

its (7,6)

Step-by-step explanation:

2x + y = 20

2(7) + 6 = 20

14 + 6 = 20

20 = 20

6x - 5y = 12

6(7) - 5(6) = 12

42 - 30 = 12

12 = 12

Answer:

$y=0.46591x+7.71591$

Step-by-step explanation:

Labelled points are $(21,\: 17.5)=(x_1,\:y_1) \: \&\:(43,\: 27.75)=(x_2,\:y_2)$

Slope of line (m) $=\frac{27.75-17.5}{43-21} =\frac{10.25}{22} =\frac{41}{88}$

Equation of line in point - slope form is given as:

$y-y_1 = m(x-x_1)$

$\therefore y-17.5= \frac{41}{88} (x-21)$

$\therefore y= \frac{41}{88} x-\frac{861}{88}+17.5$

$\therefore y= \frac{41}{88} x+17.5-\frac{861}{88}$

$\therefore y= \frac{41}{88} x+\frac{1,540-861}{88}$

$\therefore y= \frac{41}{88} x+\frac{679}{88}$

$\therefore y=0.465909091x+7.71590909$

$\therefore y=0.46591x+7.71591$

The number of problems assigned as homework by a savvy math professor is a function of the length of the class on a particular d

uysha [10]

Answer:f(t)=4/9t — 12

Step-by-step explanation:

1. 4 is being multiplied by t first then divided by 9 not by 4/9 so there shouldn’t be any parentheses.

2. 12 is being subtracted from this so it should be 4/9t—12.

3. Final answer: f(t)= 4/9t — 12
