F (x) = x+3/x-5 I think that’s right I’m not sure :)
any number larger than 1 or less than -1 will result enlargment (with center at (0,0)
so answers are:
10: enlargement
11: 2/5 = 0.4 reduction
12: redusction
13: 1 isometric
14: enlargment
15: reduction 16: scale is 1.5
17: scale is 0.5
18: scale is 0.5 19 triangles are not scaled. ther are different .
Algebraic equations include "variable" which are unknowns that you have to solve the equation to find out their value
Answer:
C: {−5, 1)
Step-by-step explanation:
Starting with −2|−2x−4|=−12, divide both sides by -2:
|−2x−4| = 6
Reduce this by dividing all terms by 2:
|-x - 2| = 3
This is equivalent to x + 2 = 3 and x + 2 = - 3
Solving thse two equations, we get x = 1 and x = -5
And so the solution set is C: {−5, 1)
Answer:
Step-by-step explanation:
RT = sqrt(20^2 - 16^2)
RT = sqrt(400 - 256)
RT = sqrt(144)
RT = 12
SR/ST= QR/QT
SR/12 = 20/16
SR = 12 x 20 / 16
SR = 240/16
SR = 15
answer is C.
15 Units
