jek_recluse [69]2 years ago
3 0

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

                     y-(12*x^2-9*x+4)=0 

Step by step solution :<span>Step  1  :</span><span>Equation at the end of step  1  :</span><span> y - (((22•3x2) - 9x) + 4) = 0 </span><span>Step  2  :</span><span>Equation at the end of step  2  :</span><span> y - 12x2 + 9x - 4 = 0 </span><span>Step  3  :</span>Solving a Single Variable Equation :

<span> 3.1 </span>    Solve  <span> <span>y-12x2+9x-4</span> </span> = 0 

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Which of the following could not be a value of n? side lengths of 9 and 13
daser333 [38]
The correct answer here would be D. And that is because, in a triangle, the sum of 2 of the sides has to be greater than the third side for all sides.  If we add 22 and 13 we get 35, and 35 is greater than 9, for sure. But if we add 13 and 9 we get 22 which is not greater than the third side length of 22; it would be collinear with the side length and it has to be greater than the side length.

Adult tickets to an amusement park cost x dollars. Children's tickets cost y dollars. The Henson family bought 3 adult and 1 chi
Alex787 [66]

Henson's cost: 3x+y=203

Garcia's cost: 2x+3y=189

Step-by-step explanation:

Given,

Cost of each adult ticket = x dollars

Cost of 3 adult ticket = 3x

Cost of 2 adult ticket = 2x

Cost of each child ticket = y dollar

Cost of 3 child ticket = 3x

Henson's cost;

3 adult tickets + 1 child ticket = $203

3x+y=203

Garcia's cost;

2 adult tickets + 3 child tickets = $189

2x+3y=189

Henson's cost: 3x+y=203

Garcia's cost: 2x+3y=189
