Answer:
The value of 'x' is 1 and 'y' is 2. So, the point is (1, 2).
Step-by-step explanation:
Given:
The given pair of linear equations are:
In order to solve by elimination method, we have to eliminate any one variable using mathematical operations. Let us eliminate 'y'.
Multiplying the first equation by 2 and adding the result to the second equation. This gives,
Now, the value of 'y' can be calculated by plugging in 1 for 'x' in the first equation. This gives,
Therefore, the value of 'x' is 1 and 'y' is 2.
The solution is (1, 2).
Answer:
a=-2
Step-by-step explanation:
Let me know if you need the steps tho.
So using the formula for the volume of a cone:
r^2pi x h/3
The height is always 4 times the radius, so:
h=4r
Now putting the values into the original formula:
r^2pi x 4r/3
Now to see how much the radius increases per second:
r^2pi x 4r/3=300pi
r^2 x 4r/3=300
r^2 x 4r=900
r^2 x r=225
r^3=225
The radius increases by the cubic square root of 225 cm per second.
f(s)= 225^1/3 cm
Answer:
B=48 white flowers
Step-by-step explanation:
For 3 pink flowers=2 white flowers
1 pink flower=2/3 white flowers
Now
72 pink flower=(2/3)×72 white flowers
72 pink flowers=2×24 white flowers
72 pink flowers=48 white flowers
