To solve this problem yu must apply the proccedure shown below:

 1. You have that the <span>focus of the parabola is located at (0,–2) and the directrix is represented by y=2. Therefore, you have:
</span>
 √(x0-0)²+(y0-(-2))²=|y-2|

 2. By simplifying and clearing x², you obtain:

 (√x0²+(y0+2)²)²=(y0-2)²
 x0²+(y0+2)²=(y0-2)²

 { Note: x0²=x and y0=y)

 x²=-8y

 The answer is: x²=-8y

Hey there! :)

Answer:

56.7 kg.

Step-by-step explanation:

Use the density formula to solve for the mass:

D = m/V.

Rearrange in terms of mass, or 'm':

DV = m.

Solve for the volume:

0.06 × 0.9 × 1.5 = 0.081 m³.

Plug this into the equation along with the density:

700 × 0.081 = 56.7 kg.

Solve each system of equation by substitution y=-x+5 x+2y=2​
Likurg_2 [28]

Answer:

x = 8

y = -3

Step-by-step explanation:

Given :

y = -x + 5 ...................... equation 1

x + 2y = 2 ........................ equation 2

solving the system of linear equation by substitution method , substitute equation 1 into equation 2 , that is

x + 2(-x+5) = 2

x - 2x + 10 = 2

-x + 10 = 2

collect the like terms

10 - 2 = x

therefore :

x = 8

substitute x = 8 into equation 1 to find the value of y , that is

y = -8 + 5

y = -3

Therefore :

x = 8

y = -3

yuradex [85]
You can first distribute the number into the parenthesis: 3n + 2 - 8n. Now, combine the like terms (n): -5n + 2. It can either be -5n + 2 or 2 - 5n.
