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]

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

A jar is full of 100 coins. All of the coins are either nickels or dimes.
a. The value of the coins is $6.35. Write a linear system representing this equation.
b. Solve the system to determine how many of each type of coin is in the jar.
Answer:
73 nickels, 27 dimes
Step-by-step explanation:
x+y=100
5x+10y=635
x=100-y
5(100-y)+10y=635
500-5y+10y=635
500+5y=635
5y=135
y=27
5x+10(27)=635
5x+270=635
5x=365

73+27=100

PositiveWhat 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

HELP (0,-3) and (5,-5) what is the slope
Answer:
-2/5
Step-by-step explanation:
To find the slope, we use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -5 - -3)/( 5 - 0)
= ( -5+3)/( 5-0)
= -2/5
Hi! I can help you with joy! :)

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).

Step-by-step explanation:
So basically what's going on is that to be a function, the ordered pairs must not have the same x values. With that, it is pretty obvious choice B is correct. Please give brainliest would appreciae thanks!
Answer:
Option B
Step-by-step explanation:
As per definition of function
A relation is called to be a function if every domain of the relation has an unique range
or
f(x)=ywhere x is domain and y is range
Here
f(0)=0f(1)=2f(2)=4f(3)=4Hence it's a function

Step-by-step explanation:
I'll assume the equation is:
f(x) =x^2− 9 [assumes the "x2 is meant to be x^2]
f(x) =x^2− 9
f(24) = (24)^2 - 9

Factor out the GCF from the given polynomial.
14x - 2
Hi! I can help you with a smile! :)
First of all, the GCF stands for "Greatest Common Factor"So, what is the GCF of the polynomial?Well, 14 is divisible by 1, 2, 7, and 14.2 is only divisible by 1 and 2.Now, the GCF of both 14 and 2 is 2.So, let's factor 2.Remember, factoring looks like this:ab+ac=a(b+c)Now, let's factor our binomial (a polynomial with 2 terms)14x-2=2(7x-1)Answer:
2(7x-1)

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]
