19x+(1/2)ax=x+9 solve for x

Answers

Answer 1

Answer: 19x + ¹/₂ax = x + 9
- x - x
18x + ¹/₂ax = 9
x(18) + x(¹/₂a) = 9
x(18 + ¹/₂a) = 9
18 + ¹/₂a 18 + ¹/₂a
x = 9/(18 + ¹/₂a)

What is the equation of the graph that represents the parent function f(x^4) stretched vertically by a factor of 2, and then shifted up 3 spaces.A) g(x)= 2x^4+3

B) g(x)= 2(x^4+3)

C) g(x)= 2(x+3)^4

D) g(x)= 2x^4-3

Answers

The required transformed graph of parent graph f(x^4) is $2x^4+3$

The correct option is (A)

Transformation on Graph:

If we have a original graph of the function f (x) then

Vertical transformation by a unit = a f(x)

Horizontal compression by a unit = f(ax)

Vertical translation up a units = f(x) + a

How to find transformed graph?

Here we have given original function is f(x^4)

If the graph stretched vertically by 2 unit then transformed graph is

=2 $f(x^4)$

Also we have given the graph is shifted up 3 units

Therefore the graph will be = $2f(x^4)+3$

The correct option is (A)

This is the conclusion to the answer.

If it is 11:45 a.m., what will the time be 3 hours and 15 minutes later?4:15 p.m.
2:45 p.m.
3:15 a.m.
3:00 p.m.

Answers

If you would like to know what will the time be 3 hours and 15 minutes later, you can calculate this using the following steps:

11:45 a.m. + 3 hours and 15 minutes = 12:00 p.m. + 3 hours = 15:00 p.m. = 3:00 p.m.

The correct result would be 3:00 p.m.

In a port, the median weight of a container is 4,700 lbs, with a standard deviation of 500 pounds. 14% of the containers weigh more than 5,900 pounds.Why can't this data be represented by a normal distribution?

Because the containers are too heavy.
Because the standard deviation is too small.
Because the standard deviation is too big.
Because we don't know the number of containers.

Answers

A normal distribution works best for a very large sample size. Without knowing the number of containers, it's difficult to say whether or not it's an appropriate model for representing the distribution of container weights.

Answer:

Because the standard deviation is too small.

What is the solution to the system of equations?y = –5x + 3

y = 1

(0.4, 1)
(0.8, 1)
(1, 0.4)
(1, 0.8)

Answers

If you would like to know the solution to the system of equations, you can do this using the following steps:

y = –5x + 3
y = 1
_______________
1 = –5x + 3
5x = 3 - 1
5x = 2 /5
x = 2/5 = 0.4

(x, y) = (0.4, 1)

The correct result would be (0.4, 1).
