n - 2 = -6 × -3

n - 2 = 18

n = 18 + 2

If x=47 , find the measures of angles 1,2 and 3​

Answers

Angle x and 2 are congruent so angle 2 is also 47 degrees.

Angle x and angle 1 are supplementary so angle x and angle 1 adds up to 180 degrees.

180-47=133. Angle 1 is equal to 133.

Angle 1 and angle 3 are congruent as well so angle 3 is also 133 degrees.

what is the x and y intercept of 18x-3y=15

18(0) -3y = 15

-3y=15

now divide-3 from both sides

y= 15/-3

reduced is -5

y int = (0,-5)

18x-3(0)=15

18x=15

divide the 18 from both sides

x=15/18

reduced is 5/6

x int = 5/6

Find f(0) and f(6)

f(x)= x^2+10x+72/x^2-12x+36

Answers

Answer:

f(0) = 2     f(5) = 147

Step-by-step explanation:

f(0) = (0²+10·0+72)/(0²-12·0 + 36)   Substitute 0 for x and solve.

      = 72/36

       = 2

f(5) = (5²+10·5+72)/(5²-12·5 + 36)      Substitute 5 for x and solve.

     = (25 + 50 + 72)/(25 - 60 +36)

     = 147/1

      = 147

Write the equation in function form:
8x + 4y = 20

Answers

The answer is f(x) = 5 - 2x

Function form means just replace y with f(x).

So given 8x + 4y = 20:

Subtract 8x
4y = 20 - 8x

Divide both sides by 4
y = 5 - 2x
