1 answer:

7 0

The equation for slope between two points is (y1-y2)/x1-x2
Plug the points into the equation

-5-(-10)/-2-3
5/5
m=1
To find the equation, use y-y1=m(x-x1)
y-(-5)=1(x-(-2))
y+5=x+2
y=x+2-5
y=x-3

X - Y = 11 2x + Y = 19 where do the lines cross

katen-ka-za [31]

Just solve the equations:
A) X - Y = 11
B) 2x + Y = 19
Multiply A) by -2

A) -2X +2Y = -22 then add to B)
B) 2x + Y = 19
3Y = -3
Y=-1

A) X - -1 = 11
x = 10

2) For which value of P and W is P + W a rational number? P = 1/(sqrt(3)) And W = 1/(sqrt(6)) 2) P = 1/(sqrt(4)) and w = 1/(sqrt

fenix001 [56]

Answer:

P = 1/(sqrt(4)) and w = 1/(sqrt(9))

Step-by-step explanation:

Only the roots of perfect squares are rational numbers. 2, 3, 6, and 10 are not perfect squares, so their roots are irrational. Both 4 and 9 are perfect squares, so their roots are rational. The sum of rational numbers is a rational number.

$\dfrac{1}{\sqrt{4}}+\dfrac{1}{\sqrt{9}}=\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{5}{6}\quad\text{a rational number}$
