The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?

Answers

Answer:

One number is 4.2, the other is 18.8

Step-by-step explanation:

1.) x+y=23

(x+6y)x2=4

2.) (x+6y)x2=4 = 2x+12y=4

3.)Use elimination/substitution to solve

2x+12y=4 = x+6y=2 = x=2-6y

2-6y+y=23

4.)Solve for y

2-5y=23 -> -5y=21 -> y=4.2.

5.)Solve for x

x+4.2=23

x=18.8

Can someone please help? f(x) = |x − 2| − 4 and g(x) = 1/2x − 2 solve algebraically for x.

Answers

Answer:

x = 8, x = 0 intercepts: (8,2) (0,-2)

Step-by-step explanation:

|x − 2| is a positive value, x can be x ≥ 2 or x ≤ 2

when x≥2, then

y = x-2-4 =x-6 and y = 1/2x - 2

x-6 = 1/2x-2

1/2x=4

x = 8

When x≤2

y = -(x-2)-4 = -x - 2

y = 1/2x - 2

-x - 2 = 1/2x - 2

x = 0

solve -2(x + 4) + 9 < -11 then graph.

Answers

Answer:

-2x-8+9<-11

-2x+1<-11

-2x<-11-1

-2x<-12

divide both sides by -2

A company needs to take 10 sample sensor readings. If the sensor collects data at 1/2
of a sample per second, how long will it take the company to take all 10 samples?

Answers

It would take 20 seconds. Because it says 1/2 a sample per second, it would take 2 second to produce 1.

10 (the amount of sensors)
2 (seconds it takes to create a full sensor)

10 x 2 = 20. Therefore, your answer is 20.

Answers

Answer:

14.0°

Step-by-step explanation:

Reference angle = x

Hypotenuse = 27

Adjacent = 26.2

Apply trigonometric function, CAH:

Cos x = Adj/Hyp

Cos x = 26.2/27

Cos x = 0.97037037

x = Cos^{-1}(0.97037037)

Joanna is reading a storybook. The ratio of the number of pages she read to
the pages that remain to be read is 7:3. If the book contains 500 pages in all,
how many pages did Joanna read and how many pages remain to be read?

Answers

Answer:

The amount of pages that remain to be read is 150 pages

Step-by-step explanation:

Okay if we know it's in 7:3 ratio we can easily add them both to get 10, then divide 10 by 500 to get 50. SO we now know that 50 is 1 unit and since the ratio says 3 units is the answer, we multiply 50 by 3 to get 150.

An airplane is flying overhead at a constant elevation of 405 ft. A person is viewing the plane from a position 3040 ft from the base of a radio tower. The airplane is flying horizontally away from the person. If the plane is flying at the rate of 640 ft/s, at what rate is the distance between the person and the plane increasing when the plane passes over the radio tower? At the moment the plane passes over the tower, the distance between the person and plane is changing at a rate of ________ft/s

Answers

Answer:

δL/δt = 634,38 ft/s

Step-by-step explanation:

A right triangle is shaped by ( y = distance between aircraft and ground which is constant and equal to 405 f ) a person who is at ground level 3040 f away from the tower distance x = 3040 f and the line between the aircraft and the person. Then we can use Pythagoras theorem and write

L ( distance between aircraft and person )

L² = x² + y² or L² = x² + (405)²

Taken partial derivatives with respect to t we get:

2*L*δL/δt = 2*x*δx/t + 0

Then L*δL/δt = x*δx/dt

At the moment of the aircraft passing over the tower

x = 3040 ft δx/δt = 640 ft/s and L = √ ( 3040)² + (405)²

So L = √9241600 + 164025 L = √9405625 L ≈3066,9 ft

Then:

δL/δt = 3040*640/ 3066,9 units [ ft * ft/s / ft ] ft/s

δL/δt = 634,38 ft/s

Find the value of x that will make A||B
A-
2x + 50
5x - 80
B-
x = [?]

Answers

Answer:

Step-by-step explanation:

If A||B then the sum of given angles must be equal to 180°

2x + 50 + 5x - 80 = 180 add like terms

7x - 30 = 180 add 30 to both sides

7x = 210 divide both sides by 7

x = 30
