Answer:
Yes, it is linear. y=-1/2x+3/4
Step-by-step explanation:
To put it in standard form, you need to get the y by itself.
4y=-2x+3
Divide by 4.
y=-1/2x+3/4
For his long distance phone service, Ravi pays a $2 monthly fee plus 12¢ per minute. Last month, Ravi's long distance bill was $12.68. For how many minutes was Ravi billed?
Answer:
[tex]89\ \text{minutes}[/tex]
Step-by-step explanation:
Let the number of minutes Ravi spoke for be [tex]x[/tex]
The fixed monthly fee is $2
Per minute Ravi is charged 12¢ = $0.12
The charge in a month will be
[tex]y=2+0.12x[/tex]
In one month Ravi was billed $12.68. So [tex]y=12.68[/tex]
[tex]12.68=2+0.12x\\\Rightarrow x=\dfrac{12.68-2}{0.12}\\\Rightarrow x=89\ \text{minutes}[/tex]
So, Ravi spoke for [tex]89\ \text{minutes}[/tex] that month.
In two or more complete sentences, explain how to solve the cube root equation, vx-1+3=0.
Answer:
(b) Along the straight line from (0, 0, 0) to (0, 1, 1), x = 0, y = 0, dx = 0, dy = 0, while z ... 6(1)(1)}dx + {2(1)+3x(1)} + {1 – 4x(1)(19°30 = S (3x' – 6)dx=-5 ... (c) The straight line joining (0,0,0) and (1, 1, 1) is given in parametric form by x = 1, y = 1, z = 1. ... From this it follows that the line integral around any closed path in R is zero, ...

Answer:
B
Step-by-step explanation:
Plug the coordinates in the answer choices to see if they give you 18.
Option A: 5(5) - 2(3) = 25- 6 = 9. Not it
Option B: 5(4) - 2(1) = 20 - 2 = 18. Works.
It has to be B because we've already tested (5,3) in option A and it wasn't correct.
A sunken ship is resting at 3,000 feet below sea level. Directly above the ship, a whale is swimming 1,960 feet below sea level. Directly above the ship and the whale is a plane flying at 8,500 feet above sea level.
Select the true statement.
a. The distance between the heights of the whale and the plane is -10,460 feet.
b. The difference in height between the whale and the plane is 10,460 feet.
c. The difference in height between the whale and the ship is -1,040 feet.
d. The distance between the heights of the whale and the ship is 1,040 feet.

Answer:
Step-by-step explanation:
we know that UPR is a straight line so QPR and QPU equals 180 degrees
since we have QPR already we just have to do 180 - 70 = 110
so 110 is our answer

c. 18
Step-by-step explanation:
What is the rectangular form of z= 40(cos(7pi/6)+ i sin(7pi/6))
a. z= 20-20i rt3
b. z= 20rt3 -20 i
c. z= -20rt3 -20 i
d. z= -20-20 i rt3
Answer:
C. [tex]z = -20\sqrt{3}-i\,20[/tex]
Step-by-step explanation:
The rectangular form of a complex number is represented by the following formula:
[tex]z = a+i\,b[/tex] (1)
Where each coefficient can be determined as function of the polar components:
[tex]a = r\cdot \cos \theta[/tex] (2)
[tex]b = r\cdot \sin \theta[/tex] (3)
Where:
[tex]r[/tex] - Magnitude of the complex number, dimensionless.
[tex]\theta[/tex] - Direction of the complex number, measured in radians.
If we know that [tex]r = 40[/tex] and [tex]\theta = \frac{7\pi}{6}[/tex], then the rectangular form of the number is:
[tex]a = 40\cdot \cos \frac{7\pi}{6}[/tex]
[tex]a = -20\sqrt{3}[/tex]
[tex]b = 40\cdot \sin \frac{7\pi}{6}[/tex]
[tex]b = -20[/tex]
The rectangular form of [tex]z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right)[/tex] is [tex]z = -20\sqrt{3}-i\,20[/tex]. The correct answer is C.

which function is the inverse of function f?
Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
That's the correct answer because for example if you plug in 1 for x + 2/7, you will get 3/7. But if you plug in 3/7 for 7x -2, you will get 1.
The x equals y.
Hope it helped! The answer is expert verified.

Micah is 6 years younger than Raul.
Write an expression to show how to find Micah's age when Raul is 14.
Answer:
Micah age = x - 6
Micah age is 8 when Raul is 14
Step-by-step explanation:
Let
Raul age = x
Micah is 6 years younger than Raul.
Micah age = x - 6
Find Micah age when Raul is 14.
Micah age = Raul age(x) - 6
= 14 - 6
= 8
Micah age = 8 years
Micah age is 8 when Raul is 14.

If you can read 20 pages in 45 minutes, how many pages can you read in 18 minutes
Answer:
[tex]8[/tex] pages
Step-by-step explanation:
First, we can find the reading speed per minute before finding how many pages can be read in 18 minutes.
[tex]s=20pages/45minute[/tex] ([tex]s[/tex] refers to reading speed)
[tex]s = \frac{4}{9}pages/minute[/tex] (divide both sides by [tex]45[/tex])
Pages read in 18 minutes [tex]= \frac{4}{9}\times18[/tex]
[tex]=8[/tex] pages
Hope this helps :)

What is 2 to the 3rd Power
Answer:
8 is the answer.
Step-by-step explanation:
Let's break down what is being asked.
2 to the third power means 2 times 2 times 2, or simply 2 times itself 3 times.
To solve, do 2 * 2 * 2.
4 * 2 = 8
2 to the third ([tex]2^{3}[/tex]) is equal to 8.
