<h3>Answer: B) -4</h3>

=========================================================

Explanation:

Point Q is located at (0,w). We see that x = 0 and y = w.

So we'll replace x with 0 and y with w. Then we solve for w.

2x+3y = -12

2(0)+3(w) = -12

0+3w = -12

3w = -12

3w/3 = -12/3

w = -4

In the second to last step, I divided both sides by 3 to undo the multiplication of 3. Saying 3w means "3 times w".

Side note: The point Q is the y intercept as this is the location where the diagonal line 2x+3y=-12 crosses the vertical y axis.

In figure 2, find x if the perimeter is 4. Does each answer make sense? Why or why not?

The value of x is equal to 1.5.

It is required to find x.

<h3>What is quadratic equation?</h3>

Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.

Given that:

So for the triangle, the perimeter would be:

$(x^{2} +x+3)+(x^{2} +2x-2)+(x^{2} +2x-9)=4$

By solving in above equation, we get

$(x^{2} +x+3)+(x^{2} +2x-2)+(x^{2} +2x-9)=4\\\\\\\2x^{2}+5x-8=4\\\\2x^{2}+5x-12=0\\\\2(x + 4)(x - 1.5)=0\\\\ x=-4\\\\ x=1.5$

So, we take x= 1.5 and neglect -4 because we can't take negative roots of the quadratic equation.

Hence, the value of x is equal to 1.5.

Rudik [331]

Answer:

AC < BC < AB

Step-by-step explanation:

Given: BC = 118

AB = 63*2 = 126

AC = 360 - (BC+AB)

AC = 360 - (118+126) = 116

Two fields at a state park are 1,000 maters from each other. On a map, the two fields are 8 centimeters apart. what scale is the

marshall27 [118]

Answer:

$\frac{1cm}{125 meters}$

Step-by-step explanation:

To find the scale, we write a ratio of $\frac{map}{real world}$ and simplify.

We know $\frac{map}{real world}=\frac{8cm}{1000 meters}$ .

We simplify to $\frac{1cm}{125 meters}$
