If ax + y=23, 3x - y = 9, and x =8, what is the value of a ?
inna [77]

Answer:

a = 1

Step-by-step explanation:

x = 8

3x - y = 9

3(8) - y = 9

24 - y = 9

-y = 9 - 24

-y = -15

y = 15

ax + y = 23

a(8) + 15 = 23

8a = 23 - 15

8a = 8

a = 8/8

a = 1

Mr. Perkins wants to rent a car for a day. It will cost the daily fee of $75 plus $0.55 per mile driven, which expression shows
Alla [95]

Answer:

B. 75 + 0.55m

Step-by-step explanation:

We know that the constant is $75. You only pay this once.

Whereas $0.55 you pay per mile. Which means that you will multiply 0.55 by how many miles you drive.

This means that the equation will look like:

75 + 0.55m

Hope this helps! :)

A certain vibrating system satisfies the equation u'' + γu' + u = 0. Find the value of the damping coefficient γ for which the q
ArbitrLikvidat [17]

Answer:

The value of the damping coefficient γ is (6/19)√29, which is approximately 1.70058.

Step-by-step explanation:

Given that a certain vibrating system satisfies the equation

u'' + γu' + u = 0

We wish to find the value of the damping coefficient γ for which the quasi period of the damped motion is 90% greater than the period of the corresponding undamped motion.

The period of the undamped motion T is 2π

The quasi period T_d is (4π)/√(4 - γ²)

Since the quasi period is 90% greater than the period of the undamped motion, we have

T_d = 1.9T

So that we can finally obtain

γ as 1.70058.

Graph y = x² + 1 by plotting the points for x = -1,0, 1 and drawing the curve.
kirza4 [7]

Answer: The points are

(-1,2)

(0,1)

(1,2)

The graph is below

=========================================================

Explanation:

The idea is to replace x with the values mentioned (one at a time) and find the paired y value

For example, if x = -1, then...

y = x² + 1

y = (-1)² + 1

y = 1 + 1

y = 2

So (-1,2) is one point on the parabola. Follow similar steps to find the other points (0,1) and (1,2)

I used GeoGebra to make the graph shown below.
