Solve the equation
(1/2)-sinx=1

Answers

Answer 1

Answer: #2. sin x (sin x + 1) = 0

sin x = 0 or sin x + 1 = 0

sin x = 0 or sin x = -1

Step-by-step explanation:

Answer 2

the value of x will be x = 210° and 330° for the given expression (1/2)-sinx=1.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given a equation (1/2)- sin x = 1

Simplifying the given expression

=>  (1/2)- sin x = 1

subtract 1/2 on both sides

=> -sin x = 1/2

=> sin x = -1/2

=> x = 210° and 330°

For all x = 0 to 360°

6≥−6(a+2) solve and find the awnser

Answers

Answer:

[tex] - 3 \geqslant a[/tex]

Step-by-step explanation:

[tex]6 \geqslant - 6(a + 2)[/tex]

distribute -6 inside the parentheses

[tex]6 \geqslant - 6a - 12[/tex]

add 12 to both sides

[tex]18 \geqslant - 6a[/tex]

divide by -6 to isolate the variable

[tex] - 3 \geqslant a[/tex]

Answer:

-3<=a

Step-by-step explanation:

1. Get the -6 away, so multiply everything by -6.  6*-6 >= -6*-6(a+2)

2. This becomes -1 <= a+2   Since if you multiply or divide anything by a negative number, you have to reverse the inequality sign.

3. Subtract 2 to get a by itself    -1-2 >= a

4. This becomes -3 >= a   which is the right answer.

(Just so you know >=  and <=  means less than or equal to and more than or equal to.)

Raina corre 7 millas en 50 minutos. A esta misma tasa, ¿qué distancia en millas correría en 75 minutos?

Answers

Responder:

10.5 millas

Explicación paso a paso:

50 / 7 = 0.14

0.14 * 75 = 10.5

Espero que esto ayude :)

Given parameters:

Distance covered by Raina = 7 miles

Time taken = 50 minutes

Unknown:

Distance covered in 75 minutes = ?

To solve this problem, we have to find the speed of Raina during the first 50 minutes.

   Speed is the distance covered with time.

      Speed  = [tex]\frac{distance}{time taken}[/tex]  

   Input the parameters and solve;

     Speed  = [tex]\frac{7 miles }{50 minutes}[/tex]   = 0.14miles/min

Now, to find the distance covered in the second run;

     Distance  = speed x time taken

                      = 0.14miles/min x 75min

                      = 10.5miles

The distance covered in miles is 10.5miles

For question 1:

Assuming that option B is [tex]x^3=1[/tex], it is not a linear function.

Linear functions have equations that do not have exponents.

For question 2:

[tex]y=-(-4)+5\\\\y=4+5\\\\\boxed{y=9}[/tex]

The option is D.

For question 3:

[tex]y=x+\frac{1}{4}\\\\ y=-\frac{1}{4}+\frac{1}{4}\\\\ \boxed{y=0}[/tex]

The option is B.

help find the slope of the line

Answers

Answer:

-3/5

Step-by-step explanation:

When finding the slope, think of it as rise/run.

Rise= up/down

run=left or right

So looking at the line, it is pointing towards -inf so the slope is negative

Then we look at 2 points.

i.e. (0,2) and (-5,5) and do the rise over run technique (or just subtract) and you get your answer!

Step-by-step explanation:

Answer:

Option A!

Step-by-step explanation:

Hey there!

To figure out the ratio of candies per packs, we divide 21 (candy) by packs (3) and we get 7. This means that there are 7 candies per pack! So, in 1 pack, there are 7 candies and when there are 35 candies, we divide 35 by 7 and get 5.

So, in one pack there are 7 candies and there are 35 candies in 5 packs.

Option A. Candy: 7 Packs:5

A function would be an equation that typically contains only non-negative integers (-) powers or even just positive integer (+) multipliers of variables, such as the quadratic function, cubed equation, and so forth, is considered as Polynomial functions.

According to the question,

The given function is:

f(x) = -3x - 9

By substituting "5" in place of "x", we get

→ f(5) = -3(5) - 9

By solving the bracket, we get

We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)

Step-by-step explanation:

Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)
