We are going to solve for x=-2, y=2/3x+3, y=2/3(-2)+3, y=5/3. Therefore, x=-2 and y=5/3

Answer:

x=-2,y=\frac{5}{3}

Step-by-step explanation:

The given system of equations is

y=\frac{2}{3}x+3...(i)\\\\x=-2...(ii)

Plugging the value of x from (ii) in equation (i) and find the value of y

y=\frac{2}{3}\times(-2)+3\\\\y=\frac{-4}{3}+3\\\\y=\frac{5}{3}

Therefore, the solution of the system of equations is

x=-2,y=\frac{5}{3}

Write the numbers 23,643 and 23,987 so they line up by place value. Explain how to line them up
weqwewe [10]

Consider the numbers 23,643 and 23,987.

Since both the given numbers have same digits at ten thousands and thousands place.

So, we can'not compare the numbers on the basis of ten thousands and thousands digit.

So, let us consider the number 23,643

Consider the place value of digit at the hundreds place. Since, the digit at hundreds place = 6.

The place value of 6 = 600

Now, let us consider the number 23,987

Consider the place value of digit at the hundreds place. Since, the digit at hundreds place = 9.

Te place value of 9 = 900

Since, 900 > 600

So, 23,643 > 23,987

Therefore, the number 23,987 is greater than the number 23,643.

8.1 liters to meters
Wittaler [7]

The US equivalent of "liters to meters" would be something like
"quarts to yards", which is equally meaningless.

Liters and meters don't even measure the same thing.  Liters describe
volume, whereas meters describe length or distance.    They don't convert
to each other .

If volume units could be converted to length units, then you (or somebody
with a slightly better grasp of his math) would be able to figure out how many
inches of gas he put into his car last week, and the cost of a foot of milk.

Hello from MrBillDoesMath!

Answer:

See Discussion below

Discussion:

A function f is even if f(-x) = f(x)


f(x)                               f(-x)                                  Are they equal?

----------------------------------------------------------------------------------------

-x^8 + 2x^6-5x           -(-x)^8 + 2(-x)^6 + 5x         No

3 abs(x) - 4                 3 abs(-x) -4                       Yes

log5 x^2                     log5 (-x)^2                        Yes

(6x)^ (1/7)                     (-6x)^(1/7)                          No

e^(x^2-x)                     e^( (-x)^2+x)                      No

(x^8 +5x^2)^(-1)           ( (-x)^8 + 5 (-x)^2) ^(-1)      Yes


Answers with Yes, above are even functions.

Regards,  

MrB

P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
