When solving using the quadratic formula, what does the discriminant tell you about the nature of the roots?

1 answer:

5 0

The discriminate is the part under the square root of the formula and gives you the amount of solutions

If the discriminate is positive there are 2 solutions, if it is 0 there is a single solution and if it is negative then there is no solution (in the real numbers), because the root is not defined for negative numbers

Answer:

x = 11

Step-by-step explanation:

ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.

Angles in an equilateral triangle are all 60°.

Thus, ∠L = 60°.

=> 3x + 27 = 60

=> 3x = 33

=> x = 11

At the local store, the cost of 1 pair of jeans is $24 and the cost of 3 pairs is $24 × 3 = $72. At the online store, the cost o

Juli2301 [7.4K]

Complete question :

Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and

ignore any taxes.

Answer:

$24, $72

$50

Step-by-step explanation:

From the table :

At local store :

2 pair of jeans cost $48

Cost of a pair :

Cost of 2 pairs / number of pairs

$48 / 2 = $24

Cost of 3 pairs :

Cost per pair * number of pairs :

$24 * 3 = $72

At online store :

Cost of Jean include a fixed fee of $6

Cost of one pair of Jean = $28

Actual cost of Jean :

$28 - $6 = $22

Hence, cost of 2 pair of jeans:

($22*2) + $6

$44 + $6 = $50

Yeah because he was at least 80% and when you add the grain and carbon that was total. Then divide the carbon. It will be 80%

Course Activity: Relationships Betwee

Alenkinab [10]

Answer:

yes

Step-by-step explanation:

A rational number is in the form p/q where p and q are both integers and the denominator q is not equal to zero. This means that the set of all real numbers are rational numbers.

Since q can be any integer apart from zero, it means that all integers are rational numbers i.e for q = 1.

Hence 2 which can be written as fraction as 2/1 is a rational number since the denominator (q = 1) is a non zero number
