Find the zeros of the following

julia-pushkina [17]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

13 ) Go...

$f(x) = {x}^{2} - 2x$

$0 = {x}^{2} - 2x$

${x}^{2} - 2x = 0$

Factor x

$x(x - 2) = 0$

$x = 0 \: \: \: or \: \: \: x - 2 = 0$

$x = 0 \: \: \: \: or \: \: \: \: x = 2$

These are the zeroes.

14 ) Go...

$f(x) = {x}^{3} + 9x + 11x - 21$

$0 = {x}^{3} + 9 {x}^{2} + 11x - 21$

${x}^{3} + 9 {x}^{2} + 11x - 21 = 0$

$(x - 1)(x + 3)(x + 7) = 0$

$x - 1 = 0 \: \: or \: \: x + 3 = 0 \: \: or \: \: x + 7 = 0 \\$

$x = 1 \: \: \: or \: \: \: x = - 3 \: \: \: or \: \: \: x = - 7 \\$

These are the zeroes.

$60 is saved in electricity bill for every 2 panels

Model, y

Amount saved, y = amount saved per panel * number of panels

Let number of panels = x

Hence, total amount saved, y ;

y = $30x

Ratio of panels to money saved :

Number of panels : amount of money saved

2 : $60

Serjik [45]

Answer:

m arc NP = 151°

Step-by-step explanation:

m arc MN = x

m arc NP = y

5x + 6 = y

x + y = 180, I will solve with substitution

x + (5x + 6) = 180

6x + 6 = 180

6x = 174

x = 29

y = 151
