The heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) according to the equation |x –

Viktor [21]

Answer: 68.5°F and 76.5°F

Step-by-step explanation:

Given: The heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) .

According to the given absolute inequality equation, where x is the temperature of house

|x – 72.5| = 4

it gives x – 72.5 ≥ -4 and x – 72.5 ≤ 4

⇒ -4 ≤ x – 72.5 ≤ 4

Adding 72.5 on both the sides, we get

⇒ -4+72.5 ≤ x ≤ 4+72.5

⇒68.5 ≤ x ≤ 76.5

Thus the minimum temperature is 68.5° F and the maximum temperature is 76.5° F.

AB and BC form a right angle at point B if A = (-3,-1) and B = (4,4) what is the equation if BC

sergejj [24]

Answer:

$7x+5y-48=0$

Step-by-step explanation:

Refer the attached figure .

We are given a line AB

Point A $=(x_1,y_1) = (-3,-1)$

Point B $=(x_2,y_2) = (4,4)$

Formula for slope 'm' when two points are given :

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting thew values

$m=\frac{4-(-1)}{4-(-3)}$

$m=\frac{5}{7}$

Since we are given that AB is perpendicular to BC

So, By property - perpendicular slopes are negative reciprocals of each other.

$\Rightarrow m_1\times m_2 =-1$

$\Rightarrow \frac{5}{7}\times m_2 =-1$

$\Rightarrow m_2 = \frac{-7}{5}$

So, Slope for line BC : $m_2 = \frac{-7}{5}$

Point B = (4,4)

Formula of equation of line : $y-y_1=m(x-x_1)$

$y-4=\frac{-7}{5}(x-4)$

$5(y-4)=-7(x-4)$

$5y-20=-7x+28$

$7x+5y-20-28=0$

$7x+5y-48=0$

Hence the equation of line BC : $7x+5y-48=0$
