A. (2,6)(5,0)
slope = (0 - 6) / (5 - 2) = -6/3 = -2

y = mx + b
slope(m) = -2
(2,6)..x = 2 and y = 6
sub and find b, the y int
6 = -2(2) + b
6 = -4 + b
6 + 4 = b
10 = b

so line A , equation is : y = -2x + 10
============================
B. (0,2)(6,6)
slope = (6 - 2) / (6 - 0) = 4/6 which reduces to 2/3

y = mx + b
slope(m) = 2/3
(0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 2/3(0) + b
2 = b

LIne B, equation is : y = 2/3x + 2
=========================
so we have :
y = 2/3x + 2
y = -2x + 10

2/3x + 2 = -2x + 10 ..multiply by 3
2x + 6 = -6x + 30
2x + 6x = 30 - 6
8x = 24
x = 24/8
x = 3

y = -2x + 10
y = -2(3) + 10
y = -6 + 10
y = 4

solution is (3,4).....3/4 is the solution to both lines <===

Find the conjugate of the complex number, use division:<br> 2+i<br> ——<br> 1+i

Fittoniya [83]

I assume you mean divide using the conjugate to rationalize the denominator and express the result in standard rectangular form.

$\dfrac{2+i}{1+i} = \dfrac{2+i}{1+i} \cdot \dfrac{1-i}{1-i} = \dfrac{2(1)-i^2-2i+i}{1^2+1^2} = \frac 3 2 - \frac 1 2 i$

A problem states: "There are 9 more children than parents in a room. There are 25 people in the room in all. How many children a

Dmitrij [34]

To work out who the unknowns in the room are, we can establish that c = p+ 9
c + p = 25. The unknowns in the room are there the total number of parents in the room, and the total number of teachers in the room.

X= 0 Find the slope of a line parallel and perpendicular

Llana [10]

Answer:

Step-by-step explanation:

x=o . so the line is parallel to x-axis.

So the line parallel to the line : x = 0

As the perpendicular line will be parallel to y-axis. so the slope of the line parallel to y-axis is undefined.

Wich of the following expressions are equivalent to - 2/3 ? select all that apply

MrRa [10]

Answer:

A, C and E

Step-by-step explanation:

Simplify each expression to lowest terms. Equivalent expressions will be any expressions which are equal after simplifying to lowest terms.

A. -1/9 * 6 = -6/9 = -2/3

B. -15/10 = -3/2

C. 12/-18 = -2/3

D. -3/4 * 2/1 = -6/4 = -3/2

E. -8/9 * 3/4 = -24/36 = -2/3
