Answer:
slope = -5 ÷ 4
Step-by-step explanation:
The equation of line can be written as,
y = mx + c
where, m is slope
and c is intercept of line.
So, transforming the given equation in above standard equation.
5x + 4y - 1 = 0
⇒ 4y = -5x + 1
⇒
Now comparing this equation with standard equation. We get,
and
Hence, Slope =
The cafeteria sold 41 corn chips and 80 potato chips.
Step-by-step explanation:
Let,
Corn chips = x
Potato chips = y
Price of corn chips = $0.80
Price of potato chips = $0.60
According to given statement;
x+y= 121 Eqn 1
0.80x+0.60y=80.80 Eqn 2
Multiplying Eqn 1 by 0.80
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 0.20
Putting y=80 in Eqn 1
The cafeteria sold 41 corn chips and 80 potato chips.

Step-by-step explanation:
The problem is basically asking for the roots, or the x-intercepts. To do this, follow the quadratic formula:
b is the second coefficient(+13)
a is the first coefficient(5)
c is the third coefficient(-6)
When the formula is negative, it just means to flip the sign from a positive to negative or negative to positive. Plug in and simplify.
