Answer:

y = -2|x| + 1.

Step-by-step explanation:

We start with y = 2x which is a straight line passing through the origin with a slope of 2.

Taking the absolute value of x ( |x| ) gives a graph shaped like a letter V with the point at the origin.

Making that negative ( y = -2|x| ) inverts it vertically and then the + 1 translates it up 1 unit.

Answer:

$P=2(S-lw)/h$

Step-by-step explanation:

we have that

The formula for the surface area of the enclosed space is

$S=lw+0.5Ph$

Solve for P

That means ------> isolate the variable P

Subtract lw both sides

$S-lw=lw+0.5Ph-lw$

$S-lw=0.5Ph$

Multiply by 2 both sides

$2(S-lw)=(2)0.5Ph$

$2(S-lw)=Ph$

Divide by h both sides

$2(S-lw)/h=Ph/h$

$2(S-lw)/h=P$

Rewrite

$P=2(S-lw)/h$

Using complete square to slove for x in the equation (x+7) (x-9)=25

Brrunno [24]

Answer:

$x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}$

Step-by-step explanation:

Apply Distributive property:

$(x+7)(x-9)=25\\\\x^2-9x+7x-63=25$

Add like terms and then add 63 to both sides of the equation:

$x^2-2x-63=25\\\\x^2-2x-63+63=25+63\\\\x^2-2x=88$

Pick the coefficient of the x term, divide it by 2 and square it:

$(\frac{2}{2})^2=1$

Add it to both sides of the equation:

$x^2-2x+1=88+1$

Rewriting the left side as a squared binomial, we get:

$(x-1)^2=89$

Apply square root to both sides:

$\sqrt{(x-1)^2}=\±\sqrt{89}\\\\x-1=\±\sqrt{89}$

And finally we need to add 1 to both sides of the equation. Then we get:

$x-1+1=\±\sqrt{89}+1\\\\x=\±\sqrt{89}+1\\\\\\x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}$

Answer:

90°,60°&30°

Step-by-step explanation:

A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle). Because the angles are always in that ratio, the sides are also always in the same ratio to each other.
