Answer:
Equation of line in 
Step-by-step explanation:
The intercept form of line is given as,
Where, line has x intercept as a and y intercept as b.
Given that x intercept as 
, so 
. Also y intercepts as 
, so 
.
Substituting the value in intercept form of line,
Since denominator are same,
Multiplying by c on both sides,
Given that point 
lies on the line. So 
and 
.
Substituting the value,
Substituting the value in
Therefore, equation of line in the standard form of equation of line is .
Given:
plot of land doubles in size.
original plot area 200 by 300 meters
Area = 200m * 300m
A = 60,000 m² original plot area
60,000m² x 2 = 120,000 m²
(200m + x)(300m + x) = 120,000 m²
60,000m² + 200m*x + 300m * x + x² = 120,000 m²
x² + 500x + 60,000 = 120,000
x² + 500x + 60,000 - 120,000 = 0
x² + 500x - 60,000 = 0
x = -b <u>+</u> (√b² - 4ac)/2a
a = 1 ; b = 500 ; c = -60,000
x = -500 + (√500² - 4(1)(-60,000)) / 2(1)
x = (-500 + (√250,000 + 240,000)) / 2
x = (-500 + 700)/ 2
x = 200 / 2
x = 100 meters
(200 + x)(300 + x) = 120,000
(200 + 100)(300 + 100) = 120,000
300 * 400 = 120,000
120,000 = 120,000
4. line them up least to greatest and the one in the middle is the median, which is 4.
Answer:
hi! you can use desmos graphing calculator to help you graph these- just look it up and plug the equation in. its nice for future use as well.
Step-by-step explanation:
and no , (5,10) isn't a solution to the equation because it falls under x≥2 but not under y<x+3. Hope this helps !
