Step-by-step explanation:

according to the drawing,

the domain = -2< x ≤ 3 => (-2 , 3]

the range = -5 ≤ y ≤ 4 => [-5, 4]

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and

ser-zykov [4K]

For this case we have the following equation:
$7x - 10y = 3
$
From here, we must substitute ordered pairs of the form:
(x, y)
If the ordered pair satisfies the equation, then it belongs to the line.
We have then:

For (8, 5):
We substitute the following values:
$x = 8

y = 5

7 (8) - 10 (5) = 3

56 - 50 = 3

6 = 3$
We observe that the equation is not satisfied and therefore, this point does not belong to the line.
Since one of the points does not belong to the line, then the equation is not a good model.

Answer:
It is not a good model. One of the points does not belong to the line.

Solve and check. 73/4=X/8 A 1/4 B 62 C 1/62 D 4

Bingel [31]

In the given question the equation given has only one variable and that is "x". So it is possible to find the exact value of x.
73/4 = X/8
We can write the given equation in an easier way for proper solving.
4 * X = 73 * 8
4X = 584
X = 584/4
= 146
The value of X comes out to be 146. So the options given here cannot be the correct options.

Consider a wire of length 12 ft. The wire is to be cut into two pieces of length x and 12−x. Suppose the length x is used to for

Marat540 [252]

Answer:

x = 8

Step-by-step explanation:

When cutting the wire we will get two pieces

x and 12 - x

If we build a circle whith x , the lenght of the circle will be x, and if we look at the equation for a lenght of a cicle 2*π*r = x

then r = x/2π

and consequentely A₁ = area of a circle = πr² A₁ = π*x/2π

A₁ = x/2

With the other piece 12 - x we have to make an square so wehave to divide that piece in four equal length

side of the square = s

s = 1/4 ( 12 - x ) and the area is A₂ = [1/4 ( 12 - x)]²

A₂ = ( 12 - x )²/16

Then A₁ + A₂ = A(t) and this area as fuction of x

A (x) = x/2 + 1/16 ( 144 + x² -24x) A (x) =[ (8x + 144 + x² -24x)]/16

Taken derivatives in both sides

A´(x) = 8 + 2x - 24 = 0

2x -16 = 0 x = 8 and s = 12 - 8 s = 4
