-2x + 3y = 1

Mathematics
1 answer:
Andre45 [30]3 years ago
6 0

Answer:

-2x+3y =1.......(1)

y=3x-9........(2)

Now,

putting the value of y in equation (1),

-2x+3(3x-9)=1

or,-2x+9x-27=1

or,7x-27=1

or,7x=28

x= 4

Now putting the value of X in equation (2),

y=3×4-9

= 12-9

=3

(x,y)=(4,3)

The ratio of the perimeters of two similar triangles is 3:7. Find the ration of the areas! Please help, I am really not sure. An
PIT_PIT [208]
I don't have a visual I can provide, but the ratio of the areas is the square of the ratio of the perimeters of a 2D figure.

Intuitively, you can imagine that the triangle is simply being "scaled up" by a factor of 7/3, so the base scales up to 7/3 its original length and the height becomes 7/3 its original height.

Therefore, the new ratio is the square of the ratio of the perimeters, which is 9:49.

Must list steps! 15 Points! Will mark brainliest! Find the roots for f(n)=n^2-6n-16
Alex_Xolod [135]

f(n)= n^2 -6n - 16

Set f(n) =0

n^2 -6n-16=0

Factor it

(n-8)(n+2)=0

Solve for n

n-8=0 n+2=0

n=8 and n =-2

Which of the following pairs of functions are inverse’s of each other?
liubo4ka [24]

The answers in C are inverses of each other.


In order to find the inverse of any equation, you simply switch the x and f(x) values and then solve for the new f(x). What it will result in is your new inverse function. If we do this for each of the problems above, only one will produce the second equation properly. See the work below for how to do it for C.


f(x) = 11x - 4 ---> Switch the x and f(x)

x = 11f(x) - 4 ----> Add 4 to both sides

x + 4 = 11f(x) ----> Divide both side by 11

\frac{x+4}{11} = f(x) ----> Now put in the correct order

f(x) = \frac{x+4}{11}


Since our inverse matches the g(x) function, this means that C is the correct answer.

What sets does radical 12 belong to
adoni [48]

Step-by-step explanation: The square root of 12 is represented in the radical form as √12 which is equal to 2√3. Since, 2√3 cannot be further simplified, hence such roots are called surds.
