Answer:

answer is 9

Step-by-step explanation:

p - ( q - (m +q) )

make m = 4

p = 5

q = 3

5 - ( 3 - ( 4+3) )

5 - ( 3 - 7 )

5 - - 4

= 9

Answer:

Step-by-step explanation:

This might look a bit confusing but its really simple when you break it down...

So what they're asking is to evaluate the problem (in other words, solve the problem.)

Step 1: Substitute the variables m = 4, p =5 and q = 3

P - (9 - (m+q)) OR

5 - (9 - ( 4 + 3)

Step 2 : Order of operation, solve in parenthesis first.

5 - (9 - ( 4 + 3))

( 9 - 7)

5 - ( 2 )

Step 3 : Solve

5 - 2 = 3

Graph the line given by 2x+y=1 and the circle given by x²+y²=10.Find all solutions to the system of equations. Verify your resul

Aleksandr-060686 [28]

Answer:

(1.8, -2.6) and (-1, 3)

Step-by-step explanation:

$2x+y=1$

$x^2+y^2=10$

From the first equation

$y=1-2x$

Applying to the second equation

$x^2+(1-2x)^2=10\\\Rightarrow x^2+1+4x^2-4x=10\\\Rightarrow 5x^2-4x-8=0$

Solving the equation we get

$x=\frac{-\left(-4\right)+\sqrt{\left(-4\right)^2-4\cdot \:5\left(-9\right)}}{2\cdot \:5}, \frac{-\left(-4\right)-\sqrt{\left(-4\right)^2-4\cdot \:5\left(-9\right)}}{2\cdot \:5}\\\Rightarrow x=1.8, -1$

At x = 1.8

Applying in first equation

$2\times 1.8+y=1\\\Rightarrow y=1-3.6\\\Rightarrow y=-2.6$

At x = -1

Applying in first equation

$2\times -1+y=1\\\Rightarrow y=1+2\\\Rightarrow y=3$

∴ The circle and line intersect at points (1.8, -2.6) and (-1, 3)

Honestly it's fun and people need to stop hating on it just because most of the people are toxic and weird. I don't play it, but It's really not worth the hate. People just hate just to hate about it.

Same with ro blox.

Which of the following functions shown in the table below is not an exponential function?

kramer

Answer:

B. f(x)

D. h(x)

Step-by-step explanation:

An exponential function will have a common ratio.

We check and see if the consecutive terms has a common ratio.

For f(x),

$\frac{5}{2} \ne \frac{10}{5}$

This is not an exponential sequence.

For g(x), we have:

$\frac{2}{1} = \frac{4}{2} = \frac{8}{4} = 2$

For h(x),

$\frac{1.25}{1} \ne \frac{1.5}{1.25}$

This is not an exponential sequence

For k(x),

$\frac{16}{64} = \frac{4}{16} = \frac{1}{4} = \frac{0.25}{1}$

The length of time it takes to get through the security checks at a very large urban airport is a random variable with mean μ =

gregori [183]

A) The population and sample mean are always the same ... in this case, it is 20.6 minutes.

b) First convert the data to z-values: 

P(X<18) = P(z < (18-20.6)/8.4) = P(z< -0.3095) 

Now, using a Standard Normal table, look up z= -0.3095 

P(X<18) = 0.3785 

Hope that helps
