PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE HELP ME!!!!!!!! THATS ALL. I WILL GIVE POINTS, FAN, MEDAL. PLEASE, I AM SO BAD AT MATH

dezoksy [38]

Please try leaving out the "I'm so bad at math" part. It doesn't help.

The given inequality is 4x + y > −6. Because of the > symbol, we must use a dashed line, not a solid one. Let's solve this for y: y > -4x - 6.

This (dashed) line has a slope of -4 and a y-intercept of (0,-6).

Plot (0,-6). Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down. Plot a new point there, at (1, -10). Draw your dashed line thru those 2 pts. Then, because we have y > -4x - 6, shade the area ABOVE this line. Done.

Answer:

The first step is to subtract 4 to both sides. Next we must multiply both sides by 2. The answer is - 20

To find the solutions to an equation of the form ax2+bx+c , use the quadratic equation: x=−b±b2−4ac√2a . What are the two soluti

lidiya [134]

Answer:

1.686

Step-by-step explanation:

Given is an quadratic equation as

$2x^2-x-4=0$

Also we are given the formula for general equation

$ax^2+bx+c$ as

$\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

Here in our equation we have

$a=2\\b=-1\\c=-4$

Hence solution would be

$\frac{1+\sqrt{1+32} }{4} ,\frac{1-\sqrt{1+32} }{4} \\\frac{1+\sqrt{33} }{4} ,\frac{1-\sqrt{33} }{4}$

Greater would be the one with positive square root

$\frac{1+\sqrt{33} }{4} \\=1.6861\\=1.686$

Which best describes the transformation that occurs from the graph of f(x)=x^2 to g(x)=(x+3)^2+4?

guajiro [1.7K]

If you have a graph of the function $f(x)=x^2$ , then you should do such transformations to get graph of the function $g(x)=(x+3)^2+4$ :
1. translate the graph of the function $f(x)=x^2$ 3 units left, then you get the graph of the function $y=(x+3)^2$ ;
2. translate the graph of the function $y=(x+3)^2$ 4 units up, then you get the graph of the function $y=(x+3)^2+4$ .
