RS + ST = RT
3x + 1 + 2x - 2 = 64
5x - 1 = 64
5x = 64 + 1
5x = 65
x = 65/5
x = 13 <==
Answer:
(-2,-6)
-2
Step-by-step explanation:
To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have
-2
this is the x coordinate of the vertex.
Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)
This is the y coordinate
which means we have (-2,-6)
the axis of symmetry is just the x coordinate of the graph
which is -2
Answer:
Answer to first question is:
You can convert all fractions to decimals. The decimal forms of rational numbers either end or repeat a pattern. If the fraction is a mixed number, change it to an improper fraction. Divide the numerator by the denominator. If the division doesn't come out evenly, round the decimal off.
Answer to second question is: 0.222222
Answer to third question is: Yes
Step-by-step explanation:
Well the way I think of it is:
3/9 as a fraction is 1/3... so 1 divided by 3 equals 0.333333 repeating. You can even write it as:
_
0.3 with the fraction bar over it because it keeps repeating.
This goes for 2/9. All you have to do is do 2 divided by 9 and you get 0.222222 repeating. You can even write it as:
<h3>
_</h3>
0.2 with the fraction bar over it because it keeps repeating.
Hope this helps, have a good day. c;
Answer:
Step-by-step explanation:
Let x be the width of the jewellery box
Given:
Length of the box is twice its width
Length of the box = 
Length of the box = 
depth of the box is equal to 2 inches less than its width.
depth of the box = 
depth of the box = 
The volume of the box is 64 inches.
Solution:
We know that the formula of the volume is.
Now we substitute all known value in above.
Therefore, the equation of the volume of the box is.
Answer:
x = 5√5
Step-by-step explanation:
x² + 10² = 15²
x² + 100 = 225
x² = 125
x = √125
x = 5√5
