Answer:

x=25.61

Step-by-step explanation:

To determine the smallest amount, in dollars , that you can charge and make a profit of atleast $415, you need to find the value of x that gives p=415.

Substitute p=415 in the given quadratic equation and solve it for x.

415=-0.5x^{2} +36x-179

x^{2} -72x+1188=0

x=\frac{-(-72)+\sqrt{(-72)^{2}-4(1)(1188)} }{2(1)}

on solving we get x=25.61

The smallest amount you could charge and make a profit of $415 is $25.61

1. −4n−8=4(−3n+2)<br> 2. a−15=4a−3<br><br> what is the solution for 1 and what is the solution for 2
Contact [7]

Answer:

n = 2 and a = - 4

Step-by-step explanation:

(1)

- 4n - 8 = 4(- 3n + 2) ← distribute parenthesis

- 4n - 8 = - 12n + 8 ( add 12n to both sides )

8n - 8 = 8 ( add 8 to both sides )

8n = 16 ( divide both sides by 8 )

n = 2

(2)

a - 15 = 4a - 3 ( subtract a from both sides )

- 15 = 3a - 3 ( add 3 to both sides )

- 12 = 3a ( divide both sides by 3 )

- 4 = a

Which of the following is the equation of a line that passes through (-2,1) and (-4,-3)?
stich3 [128]

Answer:

The equation is y= 2x+5

Step-by-step explanation:

Lets find the slope of the line through the points (-2,1) and (-4,-3).

where x1 = -2,  y1= 1,  x2= -4,  y2 = -3.

Now apply slope formula:

m= y2-y1/ x2-x1

m= -3-1/-4-(-2)

m = -4/-4+2

m= -4/-2

Divide the term by 2:

m = 2

Now we will apply point slope formula:

y-y1 = m (x-x1)

Now substitute the values in the formula:

y-1=2(x-(-2))

y-1 =2(x+2)

y-1=2x+4

Now combine the constants:

y= 2x+4+1

y=2x+5

So the equation is y= 2x+5 ....
