Answer:
x+y = 3
3x-y = 5
Step-by-step explanation:
x+y = 3
3x-y = 5
This system of equation will give the points(2,1).
Lets substitute the values x=2 and y = 1 in the equations:
x+y=3 equation 1
2+1 =3
3=3
3x-y=5 equation 2
3(2)-1=5
6-1=5
5=5
Lets solve the system:
Add the equations to eliminate y from the system:
x+y = 3
3x-y = 5
_______
4x = 8
Now divide both the sides by 4
4x/4 = 8/4
x=2
Now substitute the value of x in equation 1:
x+y=3
2+y=3
Combine the constants:
y=3-2
y=1....
Answer:
11.781 cubic inches (round accordingly)
Step-by-step explanation:
The formula for the volume of a cone is:
where r is the radius and h is the height.
For our ice cream cone:
d = 3 inches
r = 1.5 inches (the radius is half of the diameter)
h= 5 inches
So all we have to do is plug in our values and solve for the volume:
So our final answer is around 11.8 cubic inches.
Answer: 6x+8
Step-by-step explanation: the number, which is the letter can be any letter you want, that doesn’t matter. So when it says six times a number, I just used x as an example. Once you have that just add a +8 because increased means add.
4(4)-7
16-7
9
