Solve the following System Of Equations Using Substitution or Elimination Methods. Show Work.
Ostrovityanka [42]

Answer:

There are two pairs of solutions: (2,7) and (-1,4)

Step-by-step explanation:

We will use substitution.

y = x^2 + 3

y = x +5

Since the second equation is equal to y, replace y in the first equation with the second equation.

y = x^2 + 3

x + 5 = x^2 + 3

Rearrange so that one side is equal to 0.

5 - 3 = x^2 - x

2 = x^2 - x

0 = x^2 - x - 2

You may use quadratic formula or any form of factoring to find the zeros (x values that make the equation equal to 0).

a = 1, b = -1, c = -2

Zeros = \frac{-b + \sqrt{b^{2}-4ac }  }{2a} and \frac{-b - \sqrt{b^{2}-4ac }  }{2a}

Zeros = 2 and -1

Now that you have your x values, plug them into the equations to find their corresponding y values.

y = x^2 + 3

y = (2)^2 + 3

y = 7

Pair #1: (2,7)

y = x^2 + 3

y = (-1)^2 + 3

y = 4

Pair #2: (-1,4)

Therefore, there are two pairs of solutions: (2,7) and (-1,4).

b. How much money will they make if they sell it all is $62.50

a. Calculation to determine How many quarts did they make.

Given: 1 gallon =5 quarts

Hence:

5 gallons of lemonade=5×5 quarts of lemonade

5 gallons of lemonade=25 quarts of lemonade

b. Calculation to determine how much money will they make if they sell it all

Given: 1 quarts=$2.50

Hence:

25 quarts=25 ×$2.50

25 quarts=$62.50

I NEED HELP ASAP write an equivalent unit rate to running 5/4 a mile in 9 minutes
svetlana [45]

Answer:

The unit rate is 0. 14 miles per minute.

Hence, option a is correct.

Step-by-step explanation:

Given

Running of 5/4 a mile in 9 minutes.

To determine

The unit rate = ?

Given that the running 5/4 a mile in 9 minutes.

i.e.

Miles covered in 9 minutes = 5/4 or 1.25 miles

Miles covered in 1 minute = 1.25/9

                                           = 0. 14 miles per minute

Therefore, we conclude that:

The unit rate is 0. 14 miles per minute.

Hence, option a is correct.

Domain of the function of a graph with coordinates (-3,-2)
olga2289 [7]

Answer:

Domain is -3

Step-by-step explanation:

Given that coordinate of a graph is (-3, -2)

We have to find out the domain.

We know that if A and B are two sets, a mapping from A to B is the subset of cartesian product AxB.

Domain is the set of values of A which have images in B.

Use the above definition.

We have A = {-3,...} and B = {-2,....}

The mapping is from -3 to -2

Hence domain is -3
