10) Inconsistent

    [tex]\boxed{\begin{aligned}4x&+2y=6\\4y&=-8x+4\end{aligned}}[/tex]

11)  Solution: (3, 0)

12)  Solution: (-2, 1)

Step-by-step explanation:

[tex]\hrulefill[/tex]

The graph shows a single line, so the system is consistent and dependent.

Find the equation of the line by calculating its slope (m) and y-intercept (b), and then inputting these into the slope-intercept formula, y = mx + b.

The line passes through the points (0, -2) and (2, 0).

Input these points into the slope formula to calculate the slope of the line:

[tex]\textsf{Slope ($m$)}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-(-2)}{2-0}=\dfrac{2}{2}=1[/tex]

The y-intercept is b = -2.

Therefore, the slope-intercept equation of the line is:  

[tex]y=x-2[/tex]

Rearrange this by subtracting x from both sides:

[tex]-x+y=-2[/tex]

Therefore, the correct set of equations for the given system is:

[tex]\boxed{\begin{aligned}3x-3y&=6\\-x+y&=-2\end{aligned}}[/tex]

[tex]\hrulefill[/tex]

The graph shows two lines that intersect at a single point, so the system is consistent and independent.

One of the lines passes through the origin (0, 0).

The only set of equations where y = 0 when x = 0 is the set with the equation x + y = 0.

Therefore, the correct set of equations for the given system is:

[tex]\boxed{\begin{aligned}x+y&=0\\-x+y&=-8\end{aligned}}[/tex]

[tex]\hrulefill[/tex]

The graph shows two parallel lines, so the system is inconsistent .

Find the equation of one of the lines by calculating its slope (m) and y-intercept (b), and then inputting these into the slope-intercept formula, y = mx + b.

The first line passes through the points (0, 1) and (0.5, 0).

Input these points into the slope formula to calculate the slope of the line:

[tex]\textsf{Slope ($m$)}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-0}{0-0.5}=-2[/tex]

The y-intercept is b = 1.

Therefore, the slope-intercept equation of the line is:  

[tex]y=-2x+1[/tex]

Multiply all terms by 4:

[tex]4y=-8x+4[/tex]

Therefore, the correct set of equations for the given system is:

[tex]\boxed{\begin{aligned}4x&+2y=6\\4y&=-8x+4\end{aligned}}[/tex]

[tex]\hrulefill[/tex]

The solution to the graphed consistent and independent system is the point where the two lines intersect.

From observation of the given graph, the point of intersection of the two lines is (3, 0).

Answer:

  about 4.03 units

Step-by-step explanation:

The incircle of a triangle is tangent to each of the sides. The points of tangency from a given vertex are the same lengths. In a right triangle, the points of tangency from the right angle are equal in length to the radius of the incircle. These facts let us write an equation for the perimeter of the triangle in terms of the incircle radius and the side lengths:

  2(r) +2(a -r) +2(b-r) = a +b +c

  2a +2b -2r = a +b +c . . . . . simplify

  a +b -c = 2r . . . . . . . . . . . add 2r -a -b -c

  r = (a +b -c)/2 . . . . . radius of the incircle

For our triangle, with a=5, b=12, c=13, the radius is ...

  r = (5 +12 -13)/2 = 2

In our diagram, if point C is the origin, the coordinates of the incenter (D) are (2, 2). The circumcenter (E) is the midpoint of the hypotenuse, so will have coordinates (b/2, a/2) = (6, 2.5).

The distance formula can be used to find the distance between D and E:

  d = (√((6 -2)² +(2.5 -2)²) = √16.25

The distance between the incenter and circumcenter is √16.25 ≈ 4.0311.

Additional comment

In the attached diagram, we used angle bisectors to locate the incenter. This was done before we realized how simple it was to calculate its location.

Step-by-step explanation:

+++++++++++++++++++++++++++++++++++++

Answer:

30

Step-by-step explanation:

There is no remainder. You can do 84/28, which is 3, but since it is tens place, 30. You can not divide 0 to 28, so it is 0. 30+0=30

Answer:

840 28 = 30

30 = 300 to the nearest tenth

30 = 30 to the nearest hundredth

30 = 30 to the nearest thousandth

= 0 to the nearest tenth

Answer:

  (a)  1232 m²

Step-by-step explanation:

The surface area is the total of the areas of the two triangular ends and the three rectangular faces.

Each triangle area is ...

  A = 1/2bh

  A = 1/2(24 m)(7 m) = 84 m²

The sum of the areas of the rectangular faces is ...

  A = LW . . . for each of the 3 faces

  A = (19 m)(24 m) +(19 m)(7 m) +(19 m)(25 m) = (19 m)(24 +7 +25 m)

  A = (19 m)(56 m) = 1064 m²

Then the total surface area is ...

  A = lateral area + base area

  A = 1064 m² + 2(84 m²) = 1232 m² . . . . total surface area

Step-by-step explanation:

Composite functions are functions of functions. The needed composite function for given context is: [tex]P(J(y)) = \dfrac{2}{3}J(y) - 2[/tex]

Function of function, as the name suggests, are functions applied over functions themselves. This is also called function composition.

We have input. We apply one function on that input. Then we apply another function on the output obtained by the first function. This whole function application on first input is called function of functions. The resultant function which maps the input x to the final output is called function of function.

If first function is g( and the other function is f, then we can write the resultant function of function as  [tex](f\circ g)(x)[/tex]input to first function.

Thus, we have;

[tex](f\circ g)(x) = f(g(x))[/tex]

For the given case, it is given that:

To evaluate how many paintings Jojo completes in a year, we need [tex]P(J(y))[/tex]  (since, we need number of paintings and input is year, so we convert year to number of weeks by function J, and then give the output to P function to evaluate number of paintings)

Thus,

[tex]P(w) = \dfrac{2}{3}w - 2\\\\P(J(y)) = \dfrac{2}{3}J(y) - 2[/tex]

Thus,

The needed composite function for given context is: [tex]P(J(y)) = \dfrac{2}{3}J(y) - 2[/tex]

Answer:

B)  P' (-4, -4) and Q' (-1, -2)

Step-by-step explanation:

From inspection of the graph:

P = (-4, 4)

Q = (-1 ,2)

If the line PQ is reflected across the x-axis, then the x-coordinates of the points do not change, and the y-coordinates of the points become negative.  

Therefore,

P' = (-4, -4)

Q' = (-1, -2)

Reflected over x axis so x co-ordinates remains constant.

The line is present in Quadrant 2 so it will be shifted to quadrant 3.

So the rule is (x,-y)

The co-ordinates are

Answer:

According to the given Attachment

we know sum of all angles in a triangle is 180° .

On substituting the given value we obtain

➥ x + 61° + 70° + 61° = 180°

➥ x + 192° = 180°

➥ x = 180° - 192°

➥ x = -12°

So, the value of x is -12°

Step-by-step explanation:

[tex]x + 61 + 70 + 61 = 180(sum \: of \\ \: triangle) \\ \\ x + 192 = 180 \\ \\ x = 180 - 192 \\ \\ x = - 12[/tex]

Composite functions are function of functions. The unit of measurement for the composite function s(W(h)) is number of seashells collected per hour.

Functions which are formed by composing two or more functions in a way that one's input is another's output unless its the last and first function is called composite functions.

Since we're given that:

s(t) = function approximating number of seashells collected per hour

W(h) = number of hours per week spent by Mario

Thus, W(h) outputs number of hour (the time t) and when we do s(W(h)), we give s the time t.

The function s then outputs the speed (the rate of number of seashell collected per hour)

Thus, output of s(W(h)) is the rate of number of seashells collected per hour.

Thus,

The unit of measurement for the composite function s(W(h)) is number of seashells collected per hour.
