Write an equation in slope-intercept form, y = mx+b, using the given
likoan [24]

Answer:

y = \frac{-4}{3}x - 15

Step-by-step explanation:

with the point slope form, plug -9 (x coordinate) into x1, -3 (y coordinate) into y2, and -4/3 (slope) into m

y - y2 = m(x - x1)

y - (-3) = -4/3 (x - (-9))

y + 3 = -4/3 (x + 9)

y + 3 = -4/3 x + -12

y = -4/3 x - 12 - 3

y = \frac{-4}{3}x - 15

Need help with solving quadratics using the quadratic equation!
Charra [1.4K]
You need to solve the following equation:
-0.5x^2 +36x -161 = 451

Set right side to 0
-0.5x^2 +36x -612 = 0

Multiply by -2 to get rid of decimal and leading neg coefficient.
x^2 -72x + 1224 = 0

Use quadratic formula:
a = 1, b = -72, c = 1224

x = \frac{-(-72) \pm \sqrt{(-72)^2 -4(1)(1224)}}{2(1)} \\  \\ x = \frac{72 \pm \sqrt{288}}{2} \\  \\ x = 27.51, 44.49

Therefore the min price to have 451 profit is $27.51

What is y= -x^2-2x+3 in vertex form
IgorC [24]
           y = -x² - 2x + 3
      y - 3 = -x² - 2x + 3 - 3
      y - 3 = -x² - 2x
 y - 3 - 1 = -x² - 2x - 1
      y - 4 = -(x²) - (2x) - (1)
      y - 4 = -(x² + 2x + 1)
      y - 4 = -(x² + x + x + 1)
      y - 4 = -(x(x) + x(1) + 1(x) + 1(1))
      y - 4 = -(x(x + 1) + 1(x + 1))
      y - 4 = -(x + 1)(x + 1)
      y - 4 = -(x + 1)²
y - 4 + 4 = -(x + 1)² + 4 
           y = -(x + 1)² + 4

We have been given that you have 16 yellow beads 20 red beads and 24 orange beads to make identical bracelet. We are asked to find the greatest numbers of bracelets you can make using all the beads.

To solve our given problem, we need to find greatest common factor of 16, 20 and 24.

Factors of 16: 1, 2, 4, 8, 16.

Factors of 20: 1, 2, 4, 5, 10, 20.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.
