[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]

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]

i think the answer is A but it might be D

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%.

The possible values of the expression 2 - a are -5, -6, and -7.

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.

Answer:

A. 10,000

B. 10,000,000,000

C. 10

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.

Answer:

x = 50

51

Step-by-step explanation:

Question 7

This is an isosceles triangle, you can identify this, by its little tick marks on two sides of the triangle. So that means there are two 35 angles. by the rule of triangles, all angles added all together must be 180°

35 + 35 + 2x + 10 = 180

Combine like terms

70 + 10 + 2x = 180

80 + 2x = 180

2x = 180 - 80

2x = 100

2x/2 = 100/2

x = 50

Question 8

First, we need to find x to find angle Y. This is a right triangle as we can see from the square at the corner of the triangle. So, that means, that Angle Z is 90°. We know that all angles of a triangle will add up to 180 no matter what.

3x + 2x + 5 + 90 = 180

Comebine like terms

3x + 2x = 5x

90 + 5 = 95

5x + 95 = 180

5x = 180 - 95

5x = 85

5x/5 = 85/5

x = 17

Angle Y = 3x

3x

3(17)

51°

It says "Enter the value only without the degree symbol" so, 51

Step-by-step explanation:

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.

Answer:

30

Step-by-step explanation:

Given the equation;

n/10 + 7 = 10

We are to find the value of n

Subtract 7 from both sides

n/10 + 7 - 7 = 10 - 7

n/10 = 3

Cross multiply

n = 10 * 3

n = 30

Hence the solution to the equation is 30
