Help this type of work confuses me

Mathematics
1 answer:
Dmitrij [34]3 years ago
6 0

Answer/Step-by-step explanation:

Given:

-x + 3x + 1 + 4(x + 2) = 54

To solve, first open the bracket by applying the distributive property. Multiply every term you have in the bracket by 4

-x + 3x + 1 + 4x + 8 = 54

Add like terms together

6x + 9 = 54

Subtract 9 from each side

6x = 54 - 9

6x = 45

Divide both sides by 6

x = 45/6

x = 7.5

Which of the following is an extraneous solution of startroot 4 x 41 endroot = x 5? x = –8 x = –2 x = 2 x = 8
Gnom [1K]

The extraneous solution of startroot 4 x 41 endroot = x 5 will be A. -8.

<h3>What is an extraneous solution?</h3>

It should be noted that an extraneous solution simply means a root of a transformed equation which isn't part of the original equation.

✓4x + 41 = x + 5

Square both sides

4x + 41 = x² + 10x + 25

x² + 6x - 16

x(x + 8) - 2(x + 8) = 0

x + 8 = 0

x= 0 + 8 = 8

suppose X has amean of 5 and standard deviation of 2, what are the mean and standard deviation of ((3x)+4)​
skad [1K]

If you apply a linear transformation

aX+b

to a random variable X, the mean and standard deviations change as follows:

\mathbb{E}(aX+b)=a\mathbb{E}(X)+b

\sigma(aX+b)=a\sigma(X)

So, the new mean is

3\cdot 5+4=15+4=19

and the new standard deviation is

3\cdot 2=6

Rainbow [258]

Answer:

<h3><em>315 red flowers</em></h3><h3><em>420 white flowers</em></h3><h3><em>315 yellow flowers​</em></h3>

Step-by-step explanation:

1050 flowers

3/10 of them are red=> 3/10 *1050=3*105=315 red flowers

2/5, (or 4/10),  are white =>4/10 * 1050=4*105=420 white flowers

=> 1050-(315+420)=1050-735=315 yellow flowers​
