Answer:

  • y1 = -x +5
  • y2 = 2x +14
  • (x, y) = (-3, 8)

Step-by-step explanation:

We notice that x=0 is halfway between x = -1 and x = 1, so the corresponding y-intercepts will be ...

  for y1, (6+4)/2 = 5

  for y2, (12+16)/2 = 14

Each step in x is +2. The steps in y1 are -2, so the slope is -2/2 = -1.

The steps in y2 are +4, so the slope is 4/2 = 2.

Now, we have the slopes and intercepts, so we can write the system of equations as ...

  y1 = -x +5

  y2 = 2x +14

__

The y-values are shown as equal in the table for x=-3, so the solution of the system of equations is ...

  (x, y) = (-3, 8)

The triangle shown below has an area of 20 units squared. Find the missing side if the height is 8
Anuta_ua [19.1K]

Answer:

<h3>5 units </h3>

Step-by-step explanation:

Lets keep the missing side as x

And we also know that the area of Triangle is,

\frac{1}{2} bh

So taking this into consideration we can write a linear equation like this,

\frac{1}{2} bh = 20

Where height is 8,

\frac{1}{2}  \times b \times 8 = 20 \\ 4 \times b = 20 \\ b =  \frac{20}{4}  \\ b = 5

So therefore the missing side is 5

Since you know the value of s, you can substitute/plug it into the equation to find A:

A = 18s²     Plug in 1/3 into "s" since s = 1/3

A=18(\frac{1}{3} )^2     Find (1/3)²

A =18(\frac{1}{3} )^2=18(\frac{1}{3}*\frac{1}{3} )= 18(\frac{1}{9})

A = 2 square inches

In a poultry farm, 50 hens give 200 eggs in 2 days. In how many days will 20 hens give 400 eggs?.
s344n2d4d5 [400]

The number of days is 10 if, in a poultry farm, 50 hens give 200 eggs in 2 days.

<h3>What is a fraction?</h3>

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

On a poultry farm, 50 hens give 200 eggs in 2 days.

It is required to find the number of days will 20 hens require to give 400 eggs:

Let x be the number of days:

(50×2)/200 = (20x)/400

x = 10

Thus, the number of days is 10 if, in a poultry farm, 50 hens give 200 eggs in 2 days.
