It is 13.5 Simiply multiply nine times 1 1/2. An easier way to did this might be making one half into a decimal 1.5
x - y = - 11 .............( 1 )
y + 7 = - 2x ...............( 2 )
from equation ( 1 )
x - y = - 11
x = -11 + y ...........( 3)
putting x in equation ( 2 )
y + 7 = - 2 x
y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7
3 y = 15 y = 15 / 3
putting value of y in equation 3
x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)
x = -17 / 5
check
x = -11 + y
- 17 / 5 = -11 + 13 / 5
-17 /5 = -17 / 5
n = {2, 5, 0} holds true for 2n - 3 < 9
<em><u>Solution:</u></em>
Replacement set is the set of values that may be substituted for the variable.
Plug in each value from the replacement set and evaluate both sides of the inequality
If the inequality is true for a certain value, that value belongs in the solution set.
<em><u>Given equation is:</u></em>
2n - 3 < 9
<em><u>Substitute n = 2</u></em>
2(2) - 3 < 9
4 - 3 < 9
1 < 9
1 is less than 9 is true
Thus n = 2 is a solution to equation
<em><u>Substitute n = 5</u></em>
2(5) - 3 < 9
10 - 3 < 9
7 < 9
7 is less than 9 is true
Thus n = 5 is a solution to equation
<em><u>Substitute n = 0</u></em>
2(0) - 3 < 9
0 - 3 < 9
-3 < 9
-3 is less than 9 is true
Thus n = -3 is a solution to equation
Given :
A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame.
To Find :
The length of the frame.
Solution :
We know, perimeter of the rectangle is given by :

Now, it is given that 18 feet of wood is used.
So,

Therefore, length of frame is given by 3x = 6.75 feet.
Hence, this is the required solution.
Answer:
B
Step-by-step explanation:
rotate 180 --> translate up by 4: (x,y)--> (-x,-y) --> (-x,-y +4)
