Rewrite the expression by using the distributive property and collecting like terms 1/5(5x-15)-2x

Mathematics

Answer:

-x-3

Step-by-step explanation:

First, you need to distribute the 1/5 to both the term 5x and the term -15, which requires multiplication. This gives you 1x-3. The -2x can then be added on to this equation, which gives you 1x-3-2x. Combining the like terms of 1x and -2x gives you -x. The entire expression is then -x-3.

The endpoints of CD are C(−2, 0) and D(4, 9).<br> The coordinates of the midpoint M of CD are?
jenyasd209 [6]

Answer:

<em>1, 4.5</em>

Step-by-step explanation:

for midpoint

x₁ = -2, y₁ = 0

x₂ = 4, y₂ = 9

for midpoint

(x₁+x₂)/2 , (y₁+y₂)/2

(-2+4)/2 , (0+9)/2

2/2 , 9/2

1, 4.5

Hello from MrBillDoesMath!

Answer:

See Discussion section below

Discussion:

2x^2 + 5x + 3  = (2x+3)(x+1) which is Choice 3


3x^2+10x+4  =-1/3 (-3 x + sqrt(13) - 5) (3 x + sqrt(13) + 5)

I don't think any of the provided choices are right!


8x^2+10x-3 = (2x+3)(4x-1) which is Choice 2


6x^2-7x-4 = -1/24 (-12 x + sqrt(145) + 7) (12 x + sqrt(145) - 7)

I don't think any of the provided choices are right!


2x^2+x-28  =  (2x-7)(x+4) which is Choice 2


Thank you,

MrB

Nuno set up a series of dominoes. he starts by knocking over 10 dominoes. every second after that, the number of dominoes that a
vesna_86 [32]
It will take 8 seconds for all of the dominoes to fall over.

This will be an exponential function.  To find the growth rate, we can write out the terms of the sequence that goes along with it:  10, 20, 40, ...

"Growth rate" is the same as percent of increase or decrease.  We find the amount of increase and divide by the original amount:  20-10 = 10 increase; 10/10 = 1.

The exponential function is of the form
f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods.  Using the variables given to us in the problem along with this information, we have:

d(s)=10(1+1)^s&#10;\\&#10;\\2560=10(2)^s

Divide both sides by 10:
\frac{2560}{10}=\frac{10(2)^s}{10}&#10;\\&#10;\\256=2^s

We will use logarithms to solve this:
\log_2 256=s&#10;\\8=s
