Okay so you out them into the form of y=mx+b. since equation 2 is already like that you need to do it to equation 1. which is y=-4x+4. graph both equations. if it has a solution (1 point where the two lines meet) it is consistantly and independent. if they are parallel lines and the solution is 0 the system is inconsistent and the lines are dependent. if it's the same line they are consistent and dependent. the line is not the same since the y intercept is different. the slope is the same though which tells us its parallel. so the system has a solution of 0 and is inconsistent and the lines are independent.

What is the answer i'm having trouble :( click the picture
Vikentia [17]

Step-by-step explanation:

So 2 pints = 1 quart

She need 3 quart

so 2 pints × 3 = 1 quart × 3

6 pints = 3 quart

...

The she need 6 pints which is

2 cups = 1 pint

She need 6, so mutiply with 6

2 cups × 6 = 1 pint × 6

12 cups = 6 pints

Then this is the answer, you got

12 cups = 6 pints = 3 quart

She need 12 cups of water to make fruit punch

The base diameter and the height of a cone are both equal to x units.
HACTEHA [7]

By definition, the volume of a cone is given by:

V = (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)

Where,

r: cone circular base radius

h: height of the cone

Substituting values we have:

V = (\frac{1}{3}) * (\pi) * ((\frac{x}{2}) ^ 2) * (x)

Rewriting the equation we have:

V = (\frac{1}{3}) * (\pi) * (\frac{x^2}{4}) * (x)

V = (\frac{1}{12}) * (\pi) * (x ^ 3)

Answer:

An expression that represents the volume of the cone, in cubic units is:

V = (\frac{1}{12}) * (\pi) * (x ^ 3)

Note: rewrite the options again.
