Solution,
y = -x-4......(i)
3x + y =- 16.......(ii)
Now,
Substituting the value of y in equation (ii)
or, 3x + (-x-4)= -16
or,3x - x - 4 = -16
or, 2x= -16 +4
or, x = -12/2
: x = -6
Then,
Substituting the value of x in (i) equation;
or,y= -(-6) - 4
or,y= 6 - 4
: y =2
Answer:
its a square, so all sides similar
28. SV = RT/2 = 5.7/2 = 2.8
29. RT^2 = RQ^2 + QT^2
--> RT = √
(4^2 + 4^2)
RT = √32 =5.7
30. perimeter of RVS = 2.8 + 2.8 + 4 = 9.7
The slope formula is
=2−1/2−1
For the first one it would be:
-17-(-18)/0-(-13)=1/13
m=1/13
Second one:
m=−16−−9/−17−−18= -7/1
m=-7
For the there one:
Slope =−12−−13/6−−1=1/7
m=1/7

99% = 99 / 100 = 0.99
79.9 is 99% of what
= 79.9 / 99
=79.9 / 0.99

Answer:
The slope of the line is 1.3.
Hint: Click on the point (0,0) on the graph. Drag all the way up to (7,9) and stop. This should automatically create your graph that represents the relationship.
