Answer:

A) X + Y = 12

B) 10Y + x = 10x + Y -18

B) 9Y = 9x -18 multiplying A) by -9

A) -9Y = 9x - 72  adding A and B we get

0 = 18x -90

x = 5

The number is 75

Double-Check

7 + 5 = 12

75 -57 = 18

The equation (x + 6)^2 + (y + 4)^2 = 36 models the position and range of the source of a radio signal. Describe the position of
Ilia_Sergeevich [38]

Answer:

position: (-6, -4)

range: 6

Step-by-step explanation:

The equation is that of a circle centered at (-6, -4) with a radius of √36 = 6. We presume that the "position" is that of the circle's center, and the "range" is the radius of the circle.

___

The standard form equation of a circle with center (h, k) and radius r is ...

(x -h)^2 +(y -k)^2 = r^2

Matching parts of the equation, we find ...

h = -6, k = -4, r = √36 = 6.

What is the slope of the line passing through the points (-1,-7) and (-9,-2)?
nalin [4]

Answer: m = -5/8

Step-by-step explanation:

The general equation for slope is rise over run, also known as:

m=(y2-y1)/(x2-x1)

From the points (x, y), we can get all the variables we need.

(-1, -7) gives us x1 = -1 and y1 = -7

(-9, -2) gives us x2 = -9 and y2 = -2

If we plug all the values in, we get:

m = (-2 - (-7))/(-9 - (-1))

m = (-2 + 7)/(-9 + 1) the negatives cancel

m = (5)/(-8)

m = -5/8

Let XXX and YYY be the following sets: X = \{9, 25\}X={9,25}X, equals, left brace, 9, comma, 25, right brace Y = \{1, 4, 9,16,25
Dmitry_Shevchenko [17]

Answer:

The answer is "\bold{ \{\phi\}}"

Step-by-step explanation:

Given value:

\ Set\ X  = \{9, 25\} \\\\\ Set \ Y = \{ 1,4,9,16,25 \}\\\\Find: \\\\Set (X- Y) \\\\

When we subtract set X - Y it means, that it will give only, that value which is not available on the set Y.

\{X-Y\} = \{\phi\}

Can some one please help on number 8
Greeley [361]

X=13 1/3


So first  you have to add 16 +4 = 20. Then, simplify 3/2 to 1.5. Finally divide 20 by 1.5 = 13.333333333, or 13 1/3
