Answer:

They can buy up to 240 drinks.

Step-by-step explanation:

Let x = number of drinks

The price of 1 drink is 75¢ = $0.75

The price of x drinks is 0.75x

The store gives a discount of $100.

The rice of x drinks is

0.75x - 100

The total price of the drinks must be less than or equal to $80.

0.75x - 100 ≤ 80

Add 100 to both sides.

0.75x ≤ 180

Divide both sides by 0.75

x ≤ 240

Answer: They can buy up to 240 drinks.

a new line is drawn through the point (-3,6) and perpendicular to the line with x-intercept (3,0) and y intercept (0,3) . what i

Klio2033 [76]

Answer:

The equation of the new line is $y=x+9$ or $y-6=(x+3)$

Step-by-step explanation:

step 1

Find out the slope of the line with x-intercept (3,0) and y intercept (0,3)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{3-0}{0-3}=-1$

step 2

Find the slope of the new line perpendicular to the given line

we know that

If two lines are perpendicular,then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

$m_1*m_2=-1$

we have

$m_1=-1$ ----> slope of the given line

$m_2=1$ ---> slope of the new line

step 3

Find the equation of the new line in point slope form

$y-y_1=m(x-x_1)$

we have

$m=1$

$(x_1,y_1)=(-3,6)$

substitute

$y-6=(1)(x+3)$

$y-6=(x+3)$ ----> equation in point slope form

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y=x+3+6$

$y=x+9$
