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

⇒ y = \frac{-5}{4}x +\frac{1}{4}

Now comparing this equation with standard equation. We get,

m =\frac{-5}{4}

and c = \frac{1}{4}

Hence, Slope =  m =\frac{-5}{4}

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

0.80(x+y= 121)\\0.80x+0.80y=96.80\ \ \ Eqn\ 3

Subtracting Eqn 2 from Eqn 3

(0.80x+0.80y)-(0.80x+0.60y)=96.80-80.80\\0.80x+0.80y-0.80x-0.60y=16\\0.20y=16

Dividing both sides by 0.20

\frac{0.20y}{0.20}=\frac{16}{0.20}\\y=80

Putting y=80 in Eqn 1

x+80=121\\x=121-80\\x=41

The cafeteria sold 41 corn chips and 80 potato chips.

Can someone explain to me how to solve it?
lions [1.4K]

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.

Find the real zeros 4x²-16x + 2.5x​
Lapatulllka [165]

I am going to assume 2.5x is really 25x (typo).

First formulate the equality

4x^2-16x+25x=0 \\4x^2+9x=0 \\x(4x+9)=0 \\

Now two results emerge.

x_1=0, x_2=-\dfrac{9}{4}.

Hope this helps.
