Answer:
x=4 (solution) x=-14 (extraneous solution )
Step-by-step explanation:
|x+5|=9 -------original equation
Equation can be equal to +9 and -9
x+5 =9 x+5 =-9
x= 9-5 x=-9-5
x=4 (solution) x=-14 (extraneous solution )
for checking
x+5 = 9 x + 5=9
4+5= 9 -14+5=9
9=9 -9=-9

Answer:
12 questions left.
Step-by-step explanation:
Answer: A
Explanation: using the common ratio we can solve this. 24:8 = x:4
24 divided by 8 is 3.
Therefore x divided by 4 should be 3 too.
4 multiplied by 3 is 12, so x = 12.
For y:
When triangles are similar, the angles are always the same. So y is simply 40 degrees.
Answer:
7/3
7 is increased by 11 so you decrease it by 11
7-11= -4
3 is decreased by 1 so you increase it by 1
3+1= 4
-4/4
