Answer: x=3, y=2.

Step-by-step explanation:

y = - x + 4

y = x − 2

- x + 4 = x − 2

-x-x=-2-4

-2x=-6

x=(-6):(-2)=3

y=x-2=3-2=1

x=3, y=2.

Write the inverse of the function: f (x) = 2x+3
34kurt

Answer:

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

Step-by-step explanation:

To find the inverse of a function, simply 'switch' the x and y's and solve for y. y = 2x + 3 becomes x = 2y + 3. Now, solving for y, we get y = \frac{x - 3}{2}.

hope this helped! :)

Given: ∆AKM, R = 2, m∠A = 33°, O∈ AM . Find: perimeter of ∆AKM
Gwar [14]

Answer:

∆AKM is a right triangle for it is inscribed in semicircle O.

AM = diameter of semi-circle O = 2R = 2(2) = 4

%22AK%22%2F%22AM%22=cos%2833%5Eo%29

AK+=+AM%2Acos%2833%5Eo%29

AK+=+4cos%2833%5Eo%29

%22KM%22%2F%22AM%22=sin%2833%5Eo%29

KM+=+AM%2Asin%2833%5Eo%29

KM+=+4sin%2833%5Eo%29

The perimeter of a triangle is the sum of the three sides.

perimeter=AK%2BKM%2BAM

perimeter=4cos%2833%5Eo%29%2B4sin%2833%5Eo%29%2B4

Which of the following shows the division problem below in synthetic division
alexandr402 [8]

Answer:

The Answer is C

Step-by-step explanation:

Look at each coefficient next to the degree of the radical. When inputting that number for synthetic division (From greatest degree to least) you would get 8 1 and -5. The number that is the divisor is the 6, but you have to set (x - 6) to equal zero, which would get you a number of 6.
