Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
The question ask to choose among the choices that states the truth about the triangle ABC and triangle CDE which is they are similar. The statement that tells the truth is letter C. Triangle ABC is congruent to triangle CDW and also D. Side AC is congruent it side CE. I hope this will help

Answer:
a) y=-1
Step-by-step explanation:
Graph is intersecting y-axis at (0,-1)
So equation of the graph is y = - 1
f(x - n) - shift n units to right
f(x + n) - shift n units to left
f(x) + n - shift n units up
f(x) - n - shift n units down
Look at the picture.
