Please help me with this

Answer:

Option c

Step-by-step explanation:

A system of equations are given to us. And we need to solve them . The given system is

$\begin{cases} y = 2x - 3\dots 1 \\ y = x^2 - 3\dots 2 \end{cases}$

We numbered the equations here . Now put the value of equation 1 in equation 2 that is substituting y = 2x - 3 in eq. 2 .

$\implies y = x^2 - 3 \\\\\implies 2x - 3 = x^2 - 3 \\\\\implies x^2 - 2x = 0 \\\\\implies x(x-2) = 0 \\\\\implies\red{ x = 0 , 2 }$

We got two values of x as 0 & 2 . Alternatively substituting these values we have ,

$\implies y = 2 x - 3 \\\\\implies y = 2(0)-3 \qquad or \qquad y = 2(2)-3 \\\\\implies y = 0-3 \qquad or \qquad 4 - 3 \\\\\implies \red{ y = -3 , 1 }$

Thefore the required answer is ,

$\red{Option\:c} \begin{cases} (0,-3) \\ (2,1) \end{cases}$

myrzilka [38]

Answer:

a² + 4a + 4

Step-by-step explanation:

(a + 2) ² = (a + 2) ( a + 2)

= a ( a + 2) + 2 ( a + 2)

= a² + 2a + 2a + 4

= a² + 4a + 4

Find the number of vertices of a prism whose cross-section is a 60-sided polygon

pychu [463]

Answer:

A prism whose cross-section is a 60-sided polygon has 120 vertices.

Step-by-step explanation:

A polygon has the same quantity of sides and vertices, as a prism has two poligonal faces, the number of vertices is double the quantity of vertices of the 60-sided polygon. That is:

$x = 2 \cdot (60)$
