Answer:
7+x=9
Step-by-step explanation:
if you subtract 7 from both sides of this you will get x=2 so the pen is $2
Answer:
3.5
Step-by-step explanation:
Let the number be x.
x × 4 - 3 = 11
4x - 3 = 11
Add 3 on both sides.
4x - 3 + 3 = 11 + 3
4x = 14
Divide both sides by 4.
4x/4 = 14/4
x = 14/4
x = 7/2
Answer:
D
Step-by-step explanation:
change minutes to degrees
60minutes=1degree
47 mutes=?
47/60=0.78333333°
Add to 52°
52° + 0.78333333°
52.78333333°
so sin 52.7833 =0.7963540136
Answer:
48 - 3X
Step-by-step explanation:
( 52+2) - 3x - 6
54 - 3x - 6 So first we deal with the numbers in brackets and that is 52 + 2 giving us 54.
54 - 6 - 3x Then you simplify the expression that is collecting like terms so then we subtract 6 from 54
48 - 3x This is the final expression after simplifying

Answer:

Step-by-step explanation:
General equation of a parabola that opens up is
, a>0
So equation becomes
which implies option A and option B can never be true for this parabola.
Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.
So, the equation of parabola will be of the form 
Hence, option 4 that is
is correct.
