Answer:

x^2 + y = 4
x/2 - y^3 = 1

Step-by-step explanation:

Any equation with a product of variables, or with a variable in an exponent or denominator, is <em>not a linear equation</em>. Here, "product of variables" includes powers and roots—any expression with an exponent other than 1, or a total of exponents other than 1.

Find the area of a circle with diameter 10 cm . Use the value 3.14 for π , and do not round your answer. Be sure to include the

NemiM [27]

Formula for the area of a circle:

A = πr² [A = area r = radius]

The radius is $\frac{1}{2}$ (half) the diameter. Since the diameter = 10cm, the radius = 5cm.

You know:

r = 5cm Substitute/plug this into the equation

A = πr²

A = π(5)²

A = 25π -> A = 25(3.14)

A = 78.5cm²

sineoko [7]

Answer: 375 feet

Step-by-step explanation:

From the question, we are given the information that Sunni is riding a raft down a stream that is moving at a rate of 75 feet per minute.

To calculate how far downstream that she can travel in 5 minute, we have to multiply the distance covered per minute by 5. This will be:

= 75 feet × 5

= 375 feet

If you need to provide a wrap for a rice and meat mixture, you would most likely use cabbage or _______ leaves.

taurus [48]

You would most likely use lettuce leaves, because grapes are little orbs of fruit with no leaves, zuchini are funny shaped veggies, and hibiscus is a type of tree. So, the most logical answer would be lettuce leaves.
