Help me for 10 points!!

1 answer:

6 0

-2y + 2

Explanation

We have (x - y + 1) - (x + y - 1)

Let’s expand the Parentheses

= x - y + 1 - x - y + 1

Then let’s group the like terms

= (x - x) + (- y - y) + (1 + 1)

= 0 - 2y + 2

= 2y + 2

Find RA, 90: (2,5) given that point A is located at (-3, -3).

Anna71 [15]

Answer:

The value of RA is " 9.43".

Step-by-step explanation:

In the given question there is some typing mistake so, the points are:

R =(2, 5)

A= (-3, -3)

Find:

RA= ? where it is a distance (D).

Formula:

$D= \sqrt{(x_2-x_1)^2+ (y_2-y_1)^2} \\\\\ compare \ the \ value \\\\x_1 = 2\\y_1=5\\x_2=-3\\y_2= -3$

put the value in the formula:

$\Rightarrow D =\sqrt{(-3-2)^2+(-3-5)^2} \\\\\Rightarrow D =\sqrt{(-5)^2+(-8)^2} \\\\\Rightarrow D =\sqrt{25+64} \\\\\Rightarrow D =\sqrt{89} \\\\\Rightarrow D = 9.43\\$

Solve the inequality(s)<br> 2c > 2 <br> d/6 ≥ 1 <br> r + 9 ≤ 23

tatiyna

Divide both sides by 2 for the first one.
2c/2>2/2
c>1
simplify both sides for the second 1
1/6d>=1
6*(1/6d).=(6)*(1)
d>=6
For the last one
subtract 9 from both sides
r+9-9<=23-9 so that r<=14
Hope this helps!
