What are the solutions on the following system?
Oksana_A [137]
2x+y = -5.  Solve this for y.  We get y = -2x - 5.  Find y^2:  4x^2 + 20x + 25.  Substitute 4x^2 + 20x + 25 for y^2 in the first equation:

x^2 + 4x^2 + 20x + 25 = 25

Then 5x^2 + 20x = 0, so that x = 0.  Subst. 0 for x in the 2nd eqn and find the value of y.  Write your solutions as shown above:  (  ,  ) and (  ,  ).

Find the value of expression when b=9, c=5, d=1/2; expression is 1/2d + c^3 - b​
Step2247 [10]

Answer:

115 3/4

Step-by-step explanation:

\frac{1}{2} * \frac{1}{2} Because d=1/2. 1/2*1/2=1/4

C=5 so, C^3=5x5x5

C=125

Next, b=9

Then, you put everything together.

1/4+125-9=125 1/4-9

115 3/4

115 3/4+9 1/4
