Determine the discriminant for the quadratic equation 0=-2x2+3. Based on the discriminant value, how many real number solutions
nekit [7.7K]

Answer:

Option D.

The discriminat is equal to 24 which

Step-by-step explanation:

The quadratic equation is

-2x² + 3 = 0

Discriminat in quadratic equation tells us the number of solution a quadratic equation has.

For example, the quadratic equation

Ax² + bx + c = 0 will have a discriminat of b² - 4ac.

b² - 4ac is equal to the value of the discriminat and equal to the number of solutions the quadratic equation has.

In our question, we have -2x² + 3 = 0

A = -2

B = 0

C = 3

b² - 4ac = 0

Substitute the values into the above equation.

0² - 4(-2 ×3) = 0

0 + -4 × -6 = 0

24 = 0

The discriminat of the equation is 24

One coastal cholla cactus can house the nest of the cactus wren containing two adults and up to five young. Six cholla cacti are
saveliy_v [14]

Answer:

The maximum number of wren that could nest in the area based on the number of cholla cacti is:

  • <u>42 wrens</u>.

Step-by-step explanation:

The information provided by the text mentions that each cholla cactus can house a nest in which two adults and a maximum of five young will live (seven in total per nest), so this information can be represented as follows:

  • Maximum number of wrens = number of cholla cactus * 7

Since six cholla cacti are counted in the area, this value is replaced in the created equation:

  • Maximum number of wrens = 6 * 7
  • <u>Maximum number of wrens = 42 </u>

The area could house <u>a maximum of 42 wrens, where 12 would be adults and 30 would be young at most</u>.

Write an equation to match this graph.
Gekata [30.6K]

Answer:

y - 5 = 5(x - 1)

Step-by-step explanation:

Two points on the graph are (1, 5) and (7, 35).  Going from the first to the second, we see x (the 'run') increasing by 6 and y (the 'rise') increasing by 30.  Hence the slope of this line is m = rise / run = 30/6, or 5.

Using the point-slope equation, we get

y - 5 = 5(x - 1)
