Answer:
Hot dog:155 calories Cottage cheese: 200 calories
Step-by-step explanation:
Make 2 equations ---->(y=cottage cheese, x=hot dog) 2x+3y=910, 5x+2y=1,175---> solve for one variable---> x+1.5y=910---> x=605-1.5 y-----> do for both-----> x=155, y=200

Answer: 2</h3>
=========================================================
Explanation:
The function f(x) = -4x+1 is the same as y = -4x+1 where y = f(x)
Compare this to y = mx+b and we see the slope here is m = -4
---------
Now let's find the slope of g(x)
use the slope formula with any two rows you want. I'll pick on the last two rows.
m = (y2-y1)/(x2-x1)
m = (21-9)/(3-1)
m = 12/2
m = 6 is the slope of g(x)
---------
From here, we add the two slope values
(slope of f)+(slope of g) = -4+6 = 2
I^2 = (sqrt-1)^2 then the square cancels out so the answer is just
-1
