ok hi 4___________$_______
Which equation does the graph below represent?
I kinda really need help with this lol
Thanks :)
Answer:
y-intercept, where the graph crosses y-axiss is 0. that means in the equation: y = mx + b
b = 0
the m, is slope. looking at the graph you can see the points on the line are connect up 4 right 1. rise/run = slope = 4
y = 4x

Solve the 5 questions. I beg you T_T (90 points!!!)
Answer:
8) Consistent and Dependent
[tex]\boxed{\begin{aligned}3x-3y&=6\\-x+y&=-2\end{aligned}}[/tex]
9) Consistent and Independent
[tex]\boxed{\begin{aligned}x+y&=0\\-x+y&=-8\end{aligned}}[/tex]
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:
System of equationsA consistent and dependent system has infinitely many solutions. When graphed, the equations will result in overlapping lines, forming a single line.A consistent and independent system has a unique solution. When graphed, the equations will result in two lines that intersect at a single point.An inconsistent system has no solution. When graphed, the equations will result in two parallel lines that never intersect.[tex]\hrulefill[/tex]
Question 8The 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]
Question 9The 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]
Question 10The 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]
Question 11The 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).
[tex]\hrulefill[/tex]
Question 12The 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 (-2, 1).

What is the quotient of 840 divided by 28 with a remainder?
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
= 0 to the nearest hundredth
= 0 to the nearest thousandth

Solve for x. The problem is in the picture!!
Answer:
According to the given Attachment
we know sum of all angles in a triangle is 180° .
Sum of all angles in ∆ = 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]

Jojo likes to paint. She estimates the number of paintings she completes using the function P of w equals two thirds times w minus two, where w is the number of weeks she spends painting. The function J(y) represents how many weeks per year she spends painting. Which composite function would represent how many paintings Jojo completes in a year? P of J of y equals J times the quantity two thirds times w minus two P of J of y equals two thirds times J of y minus two J of P of w equals two thirds times J of y minus two J of P of w equals J times the quantity two thirds times w minus two.
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]
What are function of functions and how are they represented?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:
[tex]P(w) = \dfrac{2}{3}w - 2[/tex][tex]J(y)[/tex]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]

A triangle with sides of 5, 12, and 13 has both an inscribed and a circumscribed circle. What is the distance between the centers of those circles
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.

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:
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
