Find the slope of the line that passes through (-24, 90) and (-23, 52).

Ostrovityanka [42]

Answer:

-38

Step-by-step explanation:

The slope is rise over run. You need to find out how far one point is from the other. To do this, use the equation for slope.

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }$

Plug in the points given into the equation and solve for slope (m).

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }\\m=\frac{90-52 }{-24-(-23) }\\m=\frac{90-52 }{-24+23 }\\m=\frac{38}{-1} \\m=-38$

The slope of the line is -38.

Sam has 12 black and white photos and 18 color photos.he wants to put the photos in equal rows so each row has either black and

yawa3891 [41]

The question is asking us to determine the number of rows in which Sam can arrange his 12 black and white and 18 color photos. Sam wants to put them in the equal rows so that each row has either black and white photos only or color photos only. We have to find the GCF ( the Greatest Common Factor ) of 18 and 12. GCF ( 18, 12 ) = 6. So there should be 6 photos in each row if they have to be equal ( the equal number of photos in every row ). 18 = 6 * 3 and 12 = 6 * 2. Therefore the number of the rows is : 3 + 2 = 5. Answer: Sam can arrange his photos in 5 rows.

What the answer to this problem I need the answer as soon as possible

DENIUS [597]

I am not that sure but I believe it would be 12 and 1/2 points since that would have brought him back up to 100%. Because if it was any other it would make his score lower than 100% or higher then 100%

What is the effect on the graph of the function f(x)= x when f(x) is replaced with f(-x)?

yuradex [85]

Answer:

Step-by-step explanation:

I will outside some translation and reflection rules below:

Let a function be f(x)

Then,

f(x) + a is the function shifted a units up
f(x) - a is the function shifted a units down
f(x-b) is the function shifted b units right
f(x+b) is the function shifted b units left

Now, reflection:

f(-x) is the original reflected across y-axis
-f(x) is the original reflected in x-axis

It says to replace f(x) with f(-x), according to our rules, it is:

horizontal reflection over y-axis, answer choice D.

If you take a function f(x) = x + 2, then make f(-x), it becomes:

f(-x) = -x + 2

Graphing, you will see that they are reflections over y-axis. (graph attached).

Note:

f(x) is red

f(-x) is blue

So, answer choice is D
