Answer:

This is a really simple question!

Step-by-step explanation:

What you need to do in order to identify the sequence is, subtract the number after the first. So an example is, 19-12=7, then 26-19=7, and 33-26=7, so on so on. But every time you do that you should get 7 every time! So in order to find the next term you would have to add 7 to 47 (The last number) Which would give you, 54! Lastly to check your answer, you can solve 54-47, which is 7!

Identified sequence: +7

Next term: 54

I hope this helps! Stay safe and good luck! :)

Answer:

The next term is 54.

Step-by-step explanation:

Look carefully, and you will find that each number increases by 7.

12 + 7 = 19.

19 + 7 = 26.

26 + 7 = 33...

...and so on.

Therefore, the next term is 54 since 47 + 7 = 54.

Hope this helped!

How many solutions 2x+3y=-3 and 3x + 5y = -9

Sunny_sXe [5.5K]

Since the slopes of the two lines are the not equal, they will have only one solution. The solution will be a point and can be found using the method given below.

We can find the solutions by simultaneously solving the two equations.

From first equation, the value of y comes out to be:

$2x+3y=-3 \\ \\ 
3y=-3-2x \\ \\ 
y= \frac{-3-2x}{3}$

Using this value of y in second equation, we get:

$3x+5( \frac{-3-2x}{3} )=-9 \\ \\ 
9x-15-10x=-27 \\ \\ 
-x=-27+15 \\ \\ 
-x=-12 \\ \\ 
x=12$

Using this value of x, we can find y:

$y= \frac{-3-2x}{3}= \frac{-3-24}{3} =-9$

Therefore, there is only one solution to the given equations is which is (12, -9)

an verage person has 6x10^2 times as many red bloods cells as white blood cells. A small sample of blood has 7x10^3 white blood

m_a_m_a [10]

Answer:

4.2 x 10⁶

Step-by-step explanation:

The problem says that there are 6x 10² times as many red blood cells as white blood cells. This means that you will need to multiply the given number of white blood cells, which is 7 x 10³ by 6x 10².

To do this, first you multiply the coefficients:

7 x 6 = 42

Next you combine the exponents of the 10s, because their bases are the same, we just add the exponents when you multiply them and copy the base:

10² x 10³ = 10⁵

So the result would be:

42 x 10⁵

However the following the form of scientific notation, you need to move the decimal one more time so that means you add one more to the exponent of 10.

4.2 x 10⁶

trapecia [35]

The answer is 3x^2-19x+1

(-4x+3)-(7x-3x^2-1)
-12x+7x+3x^2+1

Combine like terms:
3x^2+(-12x+-7x)+1
= 3x^2+-19x+1
