3× + y = 8, 4× - 3y=2​

Answers

Answer 1

Answer:

x=2

y=2

Step-by-step explanation:

You can use the process of elimination

x can't be 3 because than the first question would be 9+y=8 which is even bigger than the answer.

So now, we try 2. x=2

6+y=8 which =

6+2=8

So y must be two

Then we try it on the

Second one.

8-6=2 which makes sense.

Hope it helps

Answer 2

Answer:

x = 2

y = 2

Step-by-step explanation:

3x + y = 8..…...(1)× -3

4x - 3y = 2......(2)× 1

-9x - 3y = -24.......(3)

4x - 3y = 2..…..........(4)

Cancel -3y - 3y

-9x - 4x = -24 - 2

-13x = -26

Divide both sides by -13

x = 2

Substitute for the value of y

3x + y = 8

3(2) + y = 8

6 + y = 8

y = 8 - 6

y = 2

the side of a square is 32/5, what is the area of the square

Answers

Answer: 1,024/25 or 40.96

Step-by-step explanation:

The length of one side of a square is 32/5, and all sides of a square have the same length, then all sides of the square have 32/5 as the length.

In order to get the area of the square, you need to multiply one side by another.

32/5 * 32/5 = 1,024/5 (fraction form)

32/5 = 6.4

6.4 * 6.4 = 40.96 (decimal form)

[tex]cos(150^o)=-\frac{\sqrt{3} }{2}[/tex]

Step-by-step explanation:

Recall that the value of the cosine of an angle in the unit circle is the horizontal value (x-coordinate) read-out for the point on the circle's circumference that represents the given angle.

in this case, notice that [tex]150^o[/tex] corresponds to an angle in the second quadrant, and the actual coordinate values for it are given to you. therefore, use the value you read for the x-coordinate: [tex]-\frac{\sqrt{3} }{2}[/tex]

An online company lets you download songs for $0.99 each after you have paid a $5 membership fee. Which domain would be most appropriate to calculate the cost to download songs? *

A.rational numbers greater than zero
B.whole numbers greater than or equal to one
C.integers less than or equal to zero
D.whole numbers less than or equal to one

Answers

Answer:

I assume that songs are $0.99 each.  Let x represent the number of songs you download.  Then the total cost of downloading x songs would be

C(x) = $5.00 + ($0.99/song)x

and ONLY integers = to or greater than 0 make sense here.  The domain is [0,  100) assuming you cannot buy more than 100 songs.

Personally I'd give the answer as "2, whole numbers more than or equal to zero."  However, IF you don't pay the membership fee until ready to actually order one or more songs, then "2, whole numbers greater than or equal to one" makes sense.  You'd pay $5 plus $0.99 for one song, in that case.

What is the slope and y intercept of the following linear equation:y=1/3×-2

Answers

Answer:

Step-by-step explanation:

The general formula for slope-intercept form is y = mx + b

We can see that m (slope) equals 1/3 here. We can also see that the y-intercept (b) is -2. Another way to find the y intercept is to make x equal to 0. You get 0 - 2 which equals -2

Note:

If youre ever asked for the x-intercept, make y equal to zero and solve for x.

Answers

Answer:

c = 20d + 15

Step-by-step explanation:

answer choices may help if the answer is not one of the choices; but here is the answer that it should be:

20 dollars per day is 20 times the length of rental.

15 is a cost that is added and does not change.

c = the total cost therefore:

c = 20d + 15
