Answer:

x = - 1/6 + √-119/6, and, - 1/6 - √-119/6

Step-by-step explanation:

Using the quadratic formula which is: - b ± √b² - 4ac / 2a

a = 3, b = 1, c = 10

- 1 ± √1² -4 * 3 * 10 / 2 * 3

- 1 ± √1 - 120 / 6

-1 ± √-119 / 6

= -1/6 + √119/6, or - 1/6 - √-119/6

Answer:

20 crocus
40 daffodil

Step-by-step explanation:

Let d represent the number of daffodil bulbs you buy. Then 60-d is the number of crocus bulbs. The total cost will be ...

0.45(60 -d) +0.65(d) = 35.00

27 +0.20d = 35

0.20d = 8 . . . . . . . . . subtract 27

d = 40 . . . . . . . . . . multiply by 5

60 -40 = 20 . . . . . crocus bulbs

You can buy 20 crocus bulbs and 40 daffodil bulbs for $35.

Answer:

Step-by-step explanation:

Given the equation model 4x+(-4) = -2x+8

To find the value of x, the following steps must be followed

$4x+(-4) = -2x+8\\4x-4 = -2x+8\\subtracting\ 8\ from\ both\ sides\\4x-4-8=-2x+8-8\\4x-12=-2x\\4x+2x=12\\6x=12\\x=\frac{12}{6}\\ x = 2$

The value of x is 2

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

tangare [24]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =-2\\y_{1} =4\\x_{2} =6\\x_{1} =-2$

^^^Plug these numbers into the formula for slope...

$\frac{-2 - 4}{6 - (-2)}$

$\frac{-6}{8}$

^^^Can be further simplified to...

$\frac{-3}{4}$

^^^This is your slope

Hope this helped!

Which must be true of a quadratic function whose vertex is the same as its y-intercept? The axis of symmetry for the function is

zmey [24]

Answer: The axis of symmetry is x = 0
This is basically saying that the axis of symmetry is the vertical y axis

The vertex is either the highest point or the lowest point on the parabola, depending on what the value of 'a' is. If the vertex is the y intercept, then the vertex is on the y axis. The axis of symmetry goes through the vertex.
