The required reference angle of angle 192 is 12. OPtion C is correct.
Given that,
An angle of 192°
Reference angle to be determined.
The angle can be defined as the one line inclined over another line.
Angel over angle is of 360° and angle over line is 180°
The function in mathematics to operate and diagnose the function to make the function simple or more coherent is called simplifying and the process is called simplification.
Since in the question, An angle is given of 192° its corresponding and relatable angle is to be determined.
Here, a standard measure of an angle is 180, So let the reference angle b x, for reference angle the angle must be more or less than 180. So,
x = 192 - 180
x = 12
Thus, the required reference angle of angle 192 is 12. Option C is correct.

5x = y +6
5x + 2y = 3
I forgot how to solve it I need help
Answer:
Y=3
X=9/5
Step-by-step explanation:
(1) 5x=y+6
(2) 5x+2y =3
Replace (1) to (2) => (y+6)+2y=3 => y=3
Replace y=3 to (2) => 5x = 3+6 => 5x=9 => x=9/5
9x - 6y = -21 and 6x - 12y = -6 How would I solve by substitution?
Answer:
(-3,-1)
Step-by-step explanation:
6x-12y=-6
6x=12y-6
x=2y-1
9(2y-1)-6y= -21
18y-9-6y=-21
12y= -12
y=-1
6x-12(-1)=-6
6x+12= -6
6x=-18
x=-3
Answer:
x = -3 ; y = -1
Step-by-step explanation:
Let 9x - 6y = -21 be eqn.1 & let 6x - 12y = -6 be eqn.2 .
Lets find the value of x from eqn.1
[tex]9x - 6y= -21[/tex]
[tex]=> 3(3x - 2y) = -21[/tex]
[tex]=> 3x - 2y = \frac{-21}{3} = -7[/tex]
[tex]=> x = \frac{2y - 7}{3}[/tex]
Now , lets put the value of x (which we got from eqn.1) in eqn.2 :-
[tex]6x - 12y = -6[/tex]
[tex]=> 6(x - 2y) = -6[/tex]
[tex]=> x - 2y = \frac{-6}{6} = -1[/tex]
(Putting x here)
[tex]=> \frac{2y - 7}{3} - 2y = -1[/tex]
[tex]=> \frac{2y - 7 - 6x}{3} = - 1[/tex]
[tex]=> -4 y - 7 = -1 \times 3 = -3[/tex]
[tex]=> -4y = 7 - 3 = 4[/tex]
[tex]=> y = \frac{-4}{4} = -1[/tex]
Now , lets find the value of x.
[tex]x = \frac{2y - 7}{3}[/tex]
Putting y = -0.5 gives ,
[tex]x = \frac{[2 \times (-1)] - 7}{3}[/tex]
[tex]=> x = \frac{-2 - 7}{3} = \frac{-9}{3} = -3[/tex]
At dinner, the meal cost $24 and the sales tax was $1.32. What was the tax rate? Write your answer as the percent with no % sign
Answer:
5.5
Step-by-step explanation:
Sales tax = tax rate × Cost of meal
Sales tax = $1.32
Tax rate = x%
Cost of meal = $24
Sales tax = tax rate × Cost of meal
1.32 = x% × 24
1.32 = x/100 × 24
1.32 = 24x/100
1.32 * 100 = 24x
132 = 24x
x = 132/24
x = 5.5%
= 5.5
Janice rolls a fair number cube sixty times. She rolled the number four 12 times.
What is the experimental probability of rolling the number four?
Answer:0.5
Step-by-step explanation:
60➗12
Probability of an event is the measure of its chance of occurrence. The experimental probability of Janice rolling the number four is 0.2
What is experimental probability?Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]
where, [tex]P_e(E)[/tex] is denoting experimental probability of occurrence of E.
For this case, we're specified that:
The event in consideration is "Rolling the number 4"
The times she rolled the number 4 is: 12
She got four 12 times in 60 rolls of the considered cube.
Thus, we have:
E = Rolling the number 4 on the considered cubeNumber of times E occured = 12Number of times experiment was done = 60Thus, we get:
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}} = \dfrac{12}{60} = \dfrac{1}{5} = 0.2[/tex]
Thus, the experimental probability of Janice rolling the number four is 0.2

The graph of y = f(x) is the solid black graph below. Which function represents the dotted graph?
Answer:
C (The lower left one)
Step-by-step explanation:
I saw that the vertex was equal to (-1,1) and that is the only answer that makes sense
The graph of the function y = x shifted 1 unit up and moved 1 unit to the left
so the new function is now y = (x + 1) + 1.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
By observing the figure we conclude that it shifted 1 unit up and moved 1 unit to the left.
If the original graph was y = x now it is y = (x + 1) + 1.

Suppose y varies at a constant rate of change of 0.5 with respect to x (so that Δ y = 0.5 ⋅ Δ x ), and y = 1.5 when x = 3 .
Answer and explanation:
Given the above, we find y in terms x
change in y change in x = 0.5
The formula for a straight line is y= mx+b where m is slope of the line and b is the y intercept
We substitute given values above in the straight line equation:
y=mx+b
1.5= 0.5×3+b
1.5=1.5+b
b= 0
y in terms of x for the line is therefore given by the formula :
y=0.5x+0
