Answer:
7/2 and 3
Step-by-step explanation:
using quadratic formula
{-(-13) +- √(-13)^2 - 4(2)(21) } /2(2)
-(-13)+1 / 4 = 7/2
-(-13)-1 / 4 = 3
Answer: x = 7/2 and 3
Step-by-step explanation: Rewrite and factor
2x² —13x + 21 = 0
(2x - 7)(x - 3) = 0
2x - 7 = 0. x = 7/2
x - 3 = 0 x = 3

Answer:
Problem 1: No
Problem 2: Yes
Step-by-step explanation:
Problem 1:
{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}
This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.
Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.
Problem 2:
{(0, 2), (3, 4), (-3, -2), (2, 4)}
In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.

The next term in the sequence is obtained by subtracting 4 from the previous term:
13 = 17 - 4
9 = 13 - 4
5 = 9 - 4
and so on.
Recursively, we can describe the n-th term in the sequence (denoted a(n)) as a function of the (n - 1)-th term:
a(n) = a(n - 1) - 4
starting with a(1) = 17. So we have, for instance,
a(2) = a(1) - 4 = 17 - 4 = 13
We want to find an explicit formula for a(n), meaning we want a way to determine the n-th term only as a function of n, and not any other known term in the sequence. We can iteratively apply the recursive rule above:
a(n) = a(n - 1) - 4
a(n - 1) = a(n - 2) - 4
→ a(n) = (a(n - 2) - 4) - 4 = a(n - 2) - 2×4
a(n - 2) = a(n - 3) - 4
→ a(n) = (a(n - 3) - 4) - 2×4 = a(n - 3) - 3×4
a(n - 3) = a(n - 4) - 4
→ a(n) = (a(n - 4) - 4) - 3×4 = a(n - 4) - 4×4
and so on, down to
a(n) = a(1) - (n - 1)×4
The first term is a(1) = 17, so
a(n) = 17 - 4 (n - 1) = 21 - 4n

If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring
Answers
Answer:
50 percent
Step-by-step explanation:
It is given that one of the parent with a dominant trait have brown eyes and the other parent with a recessive trait has blue eyes. They produce a twin boy with eyes that is blue in color. So the probability of the fraternal twin to transmit his allele of blue eye to his or her offspring is 50 percent.
And also the probability of the offspring to pass the allele on to his or her offspring is 50 %.
The product rule is used : 0.5 x 0.5 = 0.25 or 25%.

Hence , correct option is Option B i.e. Mel did pass the class.
How to Solve:The statement says that Mel scored C+ is Chemistry.
We will approach our answer logically by examining each option.
Option A says Mel does not like chemistry. This Cannot be true because maybe Mel likes chemistry but he just has scored less or maybe this C+ is an achievement for Mel.
Option B says that Mel did pass the class. This is possible because a student is considered as not qualified if he/she scores D or below, but Mel has scored C+ which is above the qualifying criteria.
Option C says that Mel did not achieve a passing grade for the class which is false because C+ is a passing grade scored by Mel.
Option D is Mel took math this semester which doesn't makes any sense.
hence, Option B is correct.

X-intercept is (2,0)
Y-intercept is (0,-2)
Step-by-step explanation:
The x intercept is the point at which the line hits the x-axis
in this picture, you can see that the given line hit the x-axis at (2,0)
The y intercept is the point at which the line hits the y-axis
so in this case you can see the the line hits the y-axis at (0,-2)
Bonus: if a line is horizontal it will not have an x intercept, and if a line is vertical, it will not have ay intercept
