[tex]\boxed{\boxed{\pink{\bf \leadsto Hence \ the\ correct \ option \ is \ B \ \bigg\{ x | x \in R , x \leq 7\dfrac{5}{6}\bigg\} }}}[/tex]
Step-by-step explanation:A inequality is given to us and we need to find the solution set . The inequality given to us is :-
[tex]\bf \implies x - 6\dfrac{1}{3} \leq 1\dfrac{1}{2} \\\\\bf\implies x \leq 6\dfrac{1}{3} + 1\dfrac{1}{2} \\\\\bf\implies x \leq \dfrac{19}{3} + \dfrac{3}{2}\\\\\bf\implies x \leq \dfrac{38+9}{6} \\\\\bf\implies x \leq \dfrac{47}{6} \\\\\bf\implies\boxed{\red{\bf x \leq 7\dfrac{5}{6}}} [/tex]
This means that x belongs to Real Numbers. Hence final answer would be :-
[tex]\boxed{\red{\bf \bigg\{ x | x \in R , x \leq 7\dfrac{5}{6}\bigg\}}}[/tex]
Hence option C is correct.Determine the equation of the line that goes through points (1.1) and (3.7).
Answer:
The equation of the line that goes through points (1,1) and (3,7) is [tex]\mathbf{y=3x-2}[/tex]
Step-by-step explanation:
Determine the equation of the line that goes through points (1,1) and (3,7)
We can write the equation of line in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=1, y_1=1, x_2=3, y_2=7[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{7-1}{3-1}\\Slope=\frac{6}{2}\\Slope=3[/tex]
We get Slope = 3
Finding y-intercept
y-intercept can be found using point (1,1) and slope m = 3
[tex]y=mx+b\\1=3(1)+b\\1=3+b\\b=1-3\\b=-2[/tex]
We get y-intercept b = -2
So, equation of line having slope m=3 and y-intercept b = -2 is:
[tex]y=mx+b\\y=3x-2[/tex]
The equation of the line that goes through points (1,1) and (3,7) is [tex]\mathbf{y=3x-2}[/tex]

Simplify tan0 •sin 0+ cot0 •sin0
Answer:
0
Step-by-step explanation:
tan0 •sin 0+ cot0 •sin0 =
tan(0) • sin(0) + cot(0) • sin(0) =
(tan(0) × sin(0)) + (cot(0) × sin(0)) =
(0 × 0) + (0 × 0) = 0 + 0 = 0

There are 26 students in a class. 14 of them like chocolate, 10 of them like vanilla, and 2 of them like strawberry. What percentage of students like chocolate?
Answer:
87.5%
Step-by-step explanation:
The answer would be 87.5 because there are a total of 26 students and 14 of them like chocolate. So, you would set up the fraction of 14/26 and x/100. You would then multiply 14 times 100 and divide that by 26. The answer would be 87.5. And that would be 87.5%.

Type the correct answer in the box.
The equation of the line in the graph is y = ____x + ____
(Graph in photo)
Answer:
y = -x - 1
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
On the graph, the point on the y-axis is the y-intercept. That point is (0, -1). So the y-intercept is -1.
To find the slope, find two points and put it in the slope equation.
Point A: (0, -1)
Point B: (-1, 0)
m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x{1}}[/tex]
Point A: [tex](x_{1}, y_{1})[/tex]
Point B: [tex](x_{2}, y_{2})[/tex]
m = [tex]\frac{0 - (-1)}{-1 - 0}[/tex]
m = [tex]\frac{1}{-1}[/tex]
m = -1
y = -1x - 1
In other words, y = -x - 1
Hope this helped! <3
Answer: y = -1x - 1
This means -1 goes in the first box, and -1 goes in the second box.
y = -1x - 1 is the same as y = -x - 1
========================================================
Explanation:
The two points (0,-1) and (1,-2) are on the red diagonal line.
Let's use the slope formula to compute the slope
m = (y2-y1)/(x2-x1)
m = (-2-(-1))/(1-0)
m = (-2+1)/(1-0)
m = -1/1
m = -1
The slope is -1.
The y intercept is -1 because the red line crosses the y axis at -1.
Since the y intercept is -1, this means b = -1.
With m = -1 and b = -1, we go from y = mx+b to y = -1x + (-1). This is the same as y = -1x - 1
Furthermore, that equation simplifies to y = -x - 1.
Side note: the slope and y intercept aren't always the same value.

What is the GCF of 33 and 99?
Answer:
33
Step-by-step explanation:
33= 11 * 3
99= 11 * 3 * 3
Answer:
33.
Step-by-step explanation:
33 = 3*11
99 = 3*3*11
The common factors are 3 and 11 so the GCF = 3*11 = 33.

cosa/(1+sina)+cosa/(1-sina)=2seca
prove this:)
Answer:
Please check explanations
Step-by-step explanation:
Using the difference of two squares, the lowest common multiple becomes;
1-sin^2 a
Thus, we have that;
cos a (1-sin a) + cos a (1 + sin a) /1 - sin^2 a
1 - sin^2 a = cos^2 a
That means;
{cos a - cos a sin a + cos a + cos a sin a}/ cos^2 a
= 2cos a / cos^2 a
= 2/cos a
but 1/cos a = sec a
Thus;
2/ cos a = 2 sec a

Step-by-step explanation:
Which of these expressions is equal to cos x?
Oa) sin(x - 45°)
Ob) sin x
c) sin (45° - x)
d) sin (90° - x)
Answer:
[tex]\sin \left(90^{\circ \:}-x\right)=\cos \left(x\right)[/tex]
Hence, option D is correct.
Step-by-step explanation:
Given the expression
[tex]sin\:\left(90^{\circ }\:-\:x\right)[/tex]
Using the angle difference identity
[tex]\sin \left(s-t\right)=\sin \left(s\right)\cos \left(t\right)-\cos \left(s\right)\sin \left(t\right)[/tex]
so the expression becomes
[tex]sin\:\left(90^{\circ }\:-\:x\right)=\sin \:\left(90^{\circ \:\:}\right)\cos \:\left(x\right)-\cos \:\left(90^{\circ \:\:}\right)\sin \:\left(x\right)[/tex]
as sin 90° = 1
so sin 90° cos x = cos x
also
cos 90° = 0
so con (90°) sin x = 0
Thus, the expression becomes
[tex]\sin \:\left(90^{\circ \:\:}\right)\cos \:\left(x\right)-\cos \:\left(90^{\circ \:\:}\right)\sin \:\left(x\right)=\cos \:\left(x\right)-0[/tex]
[tex]= cos (x)[/tex] ∵ [tex]\cos \left(x\right)-0=\cos \left(x\right)[/tex]
Therefore,
[tex]\sin \left(90^{\circ \:}-x\right)=\cos \left(x\right)[/tex]
Hence, option D is correct.

Tell whether x and y show direct variation. True or False?
Solve the proportion: 35/8 = 105/x
Answer:
x=24
Step-by-step explanation:
It is known that 6 < a < 10. Find all possible values of the expression 2 - a. (Please help me, I don't remember how to solve these problems!)
The possible values of the expression 2 - a are -5, -6, and -7.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To find all possible values of the expression 2 - a, we need to use the information that is given in the inequality 6 < a < 10.
We know that a is a value between 6 and 10, but not equal to 6 or 10. So, we can substitute each of the values between 6 and 10 (excluding 6 and 10) into the expression 2 - a and find the result.
We can start with the smallest possible value for a, which is 6 + 1 = 7.
So, 2 - 7 = -5
Next, we can use the value of a = 8,
so, 2 - 8 = -6
And, we can use the value of a = 9,
so, 2 - 9 = -7
Therefore, the possible values of the expression 2 - a are -5, -6, and -7.
