The solution is x = 8 and y = 2

<em><u>Solution:</u></em>

<em><u>Given are the system of equations</u></em>

2x + 3y = 22 -------- eqn 1

-2x + 5y = -6 ----- eqn 2

We can solve the system of equations by elimination method

Eqn 1 + Eqn 2

2x + 3y -2x + 5y = 22 - 6

0x + 3y + 5y = 16

8y = 16

Divide both sides of equation by 8

Substitute y = 2 in eqn 1

2x + 3(2) = 22

2x = 22 - 6

2x = 16

Thus the solution is x = 8 and y = 2

Answer:

Hello,

Step-by-step explanation:

y-intercept: x=0 ,f(0)=-10

$x^3-8x^2+17x-10\\\\=x^3-5x^2-3x^2+15x+2x-10\\\\=x^2(x-5)-3x(x-5)+2(x-5)\\\\=(x-5)(x^2-3x+2)\\\\=(x-5)(x^2-x-2x+2)\\\\=(x-5)(x(x-1)-2(x-1))\\\\=(x-5)(x-1)(x-2)\\$

x-intercepts are: 5,1,2.

A fishing hook is at an elevation of −12 m relative to sea level. Half an hour later, the fishing hook's elevation increases by

yulyashka [42]

Answer:

$-12m + 12m =0$

Step-by-step explanation:

Given

$Initial\ Position = -12m$

$Rise = 12m$

Required

Represent as an equation

The new position of the hook is calculated by:

$New\ Position = Initial\ Position + Rise$

This gives:

$New\ Position = -12m + 12m$

$New\ Position = 0$

Hence, the equation is:

$-12m + 12m =0$
