You can do these questions by substitution
for the example1
y=3x+1
you need to find a number which is suitable for x and y
when x=1
y=3(1)+1
y=4
so (1,4) is on located on the equation
when x= -1
y=3(-1)+1
y=-2
so(-1,-2) is located on the equation
and now use a ruler to line up (1,4)and(-1,-2)
and that is the equation

Find the diameter of a cone that had a volume of 56.52 cubic inches and a height of 6 inches
bulgar [2K]

Answer: 5.98 inches


Step-by-step explanation:

1. You have that the formula for calculate the volume of a cone is:

V=\frac{r^{2}h\pi}{3}

Where V is the volume, r is the radius and h is the height.

2. By definition, the diameter is twice the radius. Therefore, you need to solve for the radius:

V=\frac{r^{2}h\pi}{3} \\3V=r^{2}h\pi\\r=\sqrt{\frac{3V}{h\pi}}

3. Substitute values:

r=\sqrt{\frac{3(56.52in^{3})}{(6in)\pi}}=2.99in

4. The diameter is:

D=2r\\D=2(2.99in)\\D=5.98in

How do i simplify 2a x 3b x 4c
AlekseyPX
In the expression <span>2a x 3b x 4c,
2, 3 and 4 are the coefficients and a, b and c are the variables.
When such a multiplications is given, multiply the coefficients together and the variables together.

So the product of coefficients = 2</span>×3×4 = 24
the product of variables = a×b×c = abc

Finally multiply the  product of coefficients and  product of variables.
Final product = 24×abc = 24abc

So <u>24abc</u> is the answer.
