Hi :)

Let's remember some arithmetic w/ negative integers :

a+(-b)=a-b

a-(-b)=a-b

Now

8-(-9)=8+9=17

So the answer's 17

I hope this helps

Question on the image​
kodGreya [7K]

Let x,y be the legs of the triangle, with x[tex]\mathrm{area}_{\rm square} = y^2

\mathrm{area}_{\rm triangle} = \dfrac12 xy

The square has 3 times the area of the triangle, so

y^2 = \dfrac32 xy

Meanwhile, in the triangle we have

\tan(\theta) = \dfrac xy

Now,

y^2 = \dfrac32 xy \implies \dfrac23 = \dfrac xy \implies \boxed{\tan(\theta) = \dfrac23}

What is the x-value in the solution to the system of linear equations?
Scilla [17]

Answer: The value of x is  -2.

Step-by-step explanation:

y= 1/2x + 2

y= -3/2x-2

1/2x + 2  = -3/2x -2

         +2               +2

1/2x  + 4 = -3/2x

-1/2x            -1/2x

          4= -2x

   x= -2

I have 90% after about 75%
kkurt [141]

The lowest grade he could earn is 120% of the grade at the end of the semester.

The following statement is given:

I have 90% after about 75% of the semester.

We are asked to find the lowest grade by the end of this semester.

<h3>What is Percentage?</h3>

A percentage is a number expressed as a fraction of 100.

- 50% = 50/100 = 1/2

- 25% = 25/100 = 1/4

- 20% = 20/100 = 1/5.

We can write this statement "I have a 90% grade after about 75% of the semester" as:

90% grade  =  75% semester.............(1)


By the end of the semester means at 100% semester.

Multiplying equation (1) by 100/ 75 on both sides of the equation.

We get,

(100/75) x 90% grade = (100/75) x 75% semester

(100 x 90)/75 % grade = 100% semester

120% grade = 100%

Thus the lowest grade he could earn is 120% of the grade at the end of the semester.

List three real-world examples that can be modeled with a sinusoidal function.
Cloud [144]

Answer:

A sinusoidal function is like a sine function and it has few real life usages.

Step-by-step explanation:

1.The periodic rotations of a crankshaft in an engine.

2. The rotation of a Ferris wheel.

3. The fluctuating hours of daylight in a specific location throughout a calendar year

The sinusoidal wave is a curve that describes a smooth repetitive oscillation. In these 3 examples, we can plot the movement of the object in a graph paper and we will see a sine wave. That's why these are the real life example of sinusoidal wave.
