1. Coach Jensson wants to celebrate the final win of the
katovenus [111]
Let’s take x as the price of a taco and y as the price of a serving of nachos.
22x + 17y = 71.05. First order
10x + 5y = 27.25. Second order
Multiply the first order by 5 and the second order by 11
110x + 85y = 355.25
110x + 55y = 299.75
Subtract
30y = 55.5
y = 1.85
So 10x + 5x1.85 = 27.25
10x = 27.25 - 9.25 = 18
x = 1.8

So each taco cost $1.80 and an order of nachos cost $1.85

If a line passes through points(-2,-4) and (3,-2), the equation of the line is y +2 = 2/5(x-_____)
Otrada [13]
We have the formula: (y+4)/(-2+4) = (x+2)/(3+2);
Then, (y+4)/2 = (x+2)/5;
y+4 = (2/5)(x+2);  / - 2
y+2 =(2x)/5 + 4/5 - 2;
y + 2 = (2x)/5 - 6/5;
y + 2 = (2/5)(x - 3) is the equation of the line;
