Answer:
when y=3,X=15
here X is five times the value of y
so now when y= 5 then the value of X will be 25
hope you understand......
360 - because a right angle is 90° and there are 4 right angles in a circle , 90 x 4 = 360
Finding the perimetre: 7x+4x-3+x=12x-3
Good luck!
Answer:
Step-by-step explanation:
When x=-1
Substitute into the given equation
3(-1)-5y=19
-3-5y=19
Add 3 to both sides
-5y=22
Divide both sides by-5
y=-22/5
When x=0
3(0)-5y=19
0-5y=19
-5y=19
Divide both sides by-5
y=-19/5
When x=1
3(1)-5y=19
3-5y=19
Substrate 3 from both sides
-5y=16
Divide both sides by-5
y=-16/5
Therefore when x=-1,y=-22/5
When x=0,y=-19/5
When x=1,y=-16/5
This is most easily done using the expanded form of the expression.
∫(9 -9t +t² -t³)dt = 9t -(9/2)t² +(1/3)t³ -(1/4)t⁴ +c
