5 0

Answer:

1st one)

y = 4

2nd one)

y = -12.5

Step-by-step explanation:

5y - 20 = 0

add 20 on both sides:

⇒ 5y - 20 + 20 = 0 + 20

⇒ 5y = 20

divide 5 on both sides

⇒ \frac{5y}{y} = \frac{20}{5}

⇒ y = 4

2y + 25 = 0

subtract 25 on both sides

⇒ 2y + 25 - 25 = 0 - 25

⇒ 2y = -25

divide 2 on both sides:

⇒ \frac{2y}{2} = \frac{-25}{2}

⇒ y = -12.5

Find the equation of the quadratic function f whose graph is shown below.<br> (-4,-1)<br> (-3,-3)
Cerrena [4.2K]

The equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

Find the diagram attached.

First, we need to get the zeros of the required function. The point where the curve cuts the x-axis is the zeros.

According to the graph, the curve cuts the x-axis at x = -2 and x = -4.1

The required factors will be (x+2) and (x+4.1)

Taking the product of the factors

f(x) = (x+2)(x+4.1)

f(x) = x²+4.1x+2x +8.2

f(x) = x² + 6.1x + 8.2

Hence the equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

ankoles [38]
I'm a little confused as to how you wrote out each of the equations, but if there are 2 ounces of fruit cremes, and the box weighs 8 ounces, then there would be 6 ounces of caramels in the box.
