Carlos is using the quadratic formula to find the solutions of y=3x^2-5x-2. Which of the following will simplify to the correct

Nana76 [90]

Answer:

$Fx=\frac{5\pm\sqrt{25+24} }{6}$

Step-by-step explanation:

A quadratic equation in one variable given by the general expression:

$ax^2+bx+c$

Where:

$a\neq 0$

The roots of this equation can be found using the quadratic formula, which is given by:

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

So:

$y(x)=3x^2-5x-2=0$

As you can see, in this case:

$a=3\\b=-5\\c=-2$

Using the quadratic formula:

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}=\frac{-(-5)\pm\sqrt{(-5)^2-4(3)(-2)} }{2(3)}=\frac{5\pm\sqrt{25+24} }{6}$

Therefore, the answer is:

$Fx=\frac{5\pm\sqrt{25+24} }{6}$

Point H is on line segment GI. Given GH = x + 6, HI = x + 5, and

Vaselesa [24]

Answer:

Step-by-step explanation:

If Point H is on line segment GI, then GH+HI = GI

Given the following parameters

GH = x + 6,

HI = x + 5, and

GI = 3x + 8

To determine the length of GH, we need to get the value of x first. To get x we will substitute the given parameters into the formula as shown;

x+6+(x+5) = 3x+8

2x+11 = 3x+8

collect like terms;

2x-3x = 8-11

-x = -3

divide both sides by -1;

-x/-1 = -3/-1

x = 3

Since GH = x+6

GH = 3+6

GH = 9

Hence the numerical length of GH is 9

A student expressed a sum of two whole numbers as 5x(8+3). What were the two whole numbers?

Semmy [17]

I believe 5x(8+3) is equal to 40x + 15x meaning those two numbers are the whole numbers you are looking for.
