Answer:

(1,-5)

Step-by-step explanation:

The given system of inequalities are;

y\:

and

y\:

The point that is a solution will satisfy the two inequalities.

Checking for (1,-5)

-5\: and -5\:

-5\:: True -5\: : True

This point lies in the solution region.

Checking for (1,5)

5\: and 5\:

5\:: False 5\: : False

This point does not lie in the solution region.

Checking for (5,1)

1\: and 1\:

1\:: False 1\: : True

This point does not lie in the solution region.

Checking for (-1,5)

5\: and 5\:

5\:: True 5\: : False

This point does not lie in the solution region.

Plug the values and check if they return a true statement or not:

Plugging (x,y) = (1,-5) we have

-5 < -3 -15 < 1 + 2 \iff -5 < -18 < 3 which is false

Plugging (x,y) = (1,5) we have

5 < -3 +15 < 1 + 2 \iff 5 < 12 < 3 which is false

Plugging (x,y) = (5, 1) we have

1 < -15 + 3 < 5 + 2 \iff 1 < -12 < 7 which is false

Plugging (x,y) = (-1, 5) we have

5 < 3 +15 < -1 + 2 \iff 5 < 18 < 1 which is false

So, all of the options seem wrong.

What methods do you know that can be used to solve a quadratic equation?
zhuklara [117]

Answer: If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q)(mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x2 is 1.

Example 1 - Solve x2+7x+12=0

Step-by-step explanation:

that's the only one I remember

Question 57 need help
prisoha [69]
Okay so first we need to find the height ofn one hay barrel. To do this we must use the equations v= h×w×l

We already know 3 out of the 4 variables in the equations, in this case we are given the volume so we must work backwards.

The equation will look like this:
10 \frac{2}{3}    = h \times (1  \frac{1}{3} ) \times 4
First we must mulitpy 4 and 1 1/3 to get 16/3. The equation will now look like:
10 \frac{2}{3}  = h \times  \frac{16}{3}
Next divide 16/3 from h then from 10 2/3 to get :
2 = h
The height is 2ft. Finally multiply 2 by the number of hay barrels (8) placed upon each other becuase we're finding the height and you will get your answer of 16 ft in height.

There is a 50% chance a coin lands on heads and a 50% chance the coin lands on tails what is the probability that the coin lands
Olegator [25]

Since the probability of the coin landing leads is 1/2, simply cube 1/2 to arrive at your answer: 1/8.


You cube 1/2 because you must land heads three times in a row and each flip is independent from other flips.
