Answer:

Step-by-step explanation:

Triangles add up do 180 degrees, and you need all of the angles to get that amount

One angle is 29 degrees, the right angle is 90, and theres a

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 ,

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

WILL REWARD BRAINLIEST! The table below shows the cubes of different numbers: Number (x) 3 −3 5 −5 Cube of the number (y) 27 −27

Dmitrij [34]

f(3) = 3^3 = 27

f(-3) = (-3)^3 = -27

f(5) = 5^3 = 125

f(-5) = (-5)^3 = -125

f(6) = 27 * 6 + 18

f(6) = 180

$180 for 6 days
