Answer:

f^-1/2(x)=x/1/2-7/2

Step-by-step explanation:

Replace f(x) with y

Y=1/2x+7

Interchange the variable

X=1/2y+7

Solve For y

Rewrite the equation as

1/2y+7=x

Add -7 to both side

1/2y+7-7=x-7

1/2y=x-7

Divide each term with 1/2

1/2y/1/2=x/1/2-7/1/2

Y=x/1/2-7/2

Solve for hand replace with f^-1/2(x)

f^-1/2(x)=x/1/2-7/2

A karate studio charges $35 for the first course and $22. 50 for each course after that, even if the student leaves the course e
VashaNatasha [74]

The Cena can take 7 courses

We have given that the karate charges $35 for the first course and $22.50 for each course after that. Our total is $170.

<h3>What is the condition we can write here?</h3>

22.50x + 35 = 170

for solving this linear equation

First, subtract 35 from both sides.

22.50x = 135

isolate x so divide both sides by 22.50.

x=\frac{135}{22.50}

Therefore we get x = 6

Remember to add the additional class, so x is actually 7.

So,the Cena can take 7 courses.

Q7 Q26.) Find the quotient of the complex numbers and leave your answer in polar form.
irina [24]

To divide complex numbers in polar form, divide the r parts and subtract the angle parts. Or

</span></span></span>

z1/z2

= 3/7 (cos(π/8-π/9) + i sin(π/8 - π/9))

= 3/7 (cos(π/72) + i sin(π/72))

Hatshy [7]

Answer:

parallel

Step-by-step explanation:

Parallel lines have equal slopes.

Calculate the slopes m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 3)

m = \frac{3-2}{2+1} = \frac{1}{3}

Repeat with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1)

m = \frac{1-0}{3-0} = \frac{1}{3}

Since slopes are equal then parallel
