Answer:

1 or -9, depends on the problem, see below.

Step-by-step explanation:

-11--7+5

Two negatives make a positive so our new equation is:

-11+7+5

-11+7 is -4, so:

-4+5

And this leaves us with:

But I saw there was a parentheses, was it misplaced or was one not added? If one was not ended to the end, then the answer would be different.

(-11)-((-7)+5)

-7+5 is negative 2, so:

-11-(-2)

Once again, two negatives make a positive, so our new equation would be:

-11+2

Which gets us:

-9

Please help! Quadratic equations!

Alexeev081 [22]

Answer:

$x^2 -2x - 35 =0$

Step-by-step explanation:

Assume that the quadratic term of this equation has no coefficient. One can set the equation up in factored form using the given roots. Then expand the equation and simplify the equation to convert to standard form.

The equation in factored form is the following,

$(x+5)(x-7)=0$

Expand, multiply every term in one of the parenthesis by every term in the other,

$(x+5)(x-7)=0\\\\(x)(x)+(5)(x)-(7)(x)+(-7)(5)=0$

Simplify,

$x^2 +5x -7x -35 =0\\\\x^2 -2x -35=0$

O. Find the distance between P (10,-7) and Q (7,- 10). Leave your answer in radical form.

mr Goodwill [35]

Answer:

$\sqrt{18}$ or $3\sqrt{2}$ units.

Step-by-step explanation:

To find the distance between two points, we can use the Distance Formula.

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given:

P (10, -7) ⇒ x₁ = 10, y₁ = -7

Q (7, -10) ⇒ x₂ = 7, y₂ = -10

Substitute the given values into the formula and simplify.

$\\\implies d=\sqrt{\bold{(7-10)}^2+\bold{(-10-(-7))}^2}\\\\\implies d=\sqrt{\bold{(-3)}^2+\bold{(-10+7)}^2}\\\\\implies d=\sqrt{9+\bold{(-3)}^2}\\\\\implies d=\sqrt{\bold{9+9}}\\\\\implies d=\sqrt{\bold{18}}\\\\\implies d=\sqrt{\bold{9}\times2}\\\\\implies d=3\sqrt{2}$

The distance between points P and Q is $\sqrt{18}$ or $3\sqrt{2}$ units.
