P-6+2<-5 solve each inequality and graph its solution, i am lost

DerKrebs [107]

Answer:

P < -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

$P - 6 + 2 < -5$
$P - 4 < -5$

Step 2: Add 4 to both sides.

$P - 4 + 4 < -5 + 4$
$P < -1$

Therefore, the answer is P < -1! (Also, the graphed solution is below.)

Find the distance between R(–1, 1) and S(–4, –5) to the nearest tenth.

Bond [772]

$\text{The formula of a distance between two points}\\\\A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\\\\text{We have}\ R(-1;\ 1);\ S(-4;\ -5)\\\\\text{substitute}\\\\|RS|=\sqrt{(-4-(-1))^2+(-5-1)^2}=\sqrt{(-3)^2+(-6)^2}\\\\=\sqrt{9+36}=\sqrt{45}\approx6.7\\\\\text{Answer: 6.7}$
