For what values of m does the graph of y = 3x2 + 7x + m have two x-intercepts?

gizmo_the_mogwai [7]

So we see the leading coefient is positive (the 3 in the 3x^2 is positive) so the paraobola opens upward
so for it to have 2 x intercepts, we must have the vertex below the x axis
we must have the y value of the vertex negative

so

a hack is this
to move a function up c units, add c to whole function
also
for
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by subsituting that value for x

so

y=3x^2+7x+m
x value of vertex is
-7/(2*3)=-7/6
if we sub it in
y=3(-7/6)^2+7(-7/6)+m
y=49/12-49/6+m
we want the y value to be less than 0
so
0>49/12-49/6+m
0>49/12-98/12+m
0>-49/12+m
49/12>m

so it will have 2 x intercept for all m such that m<49/12

How many pairs of whole numbers have a sum of 40?

Alex_Xolod [135]

21 pairs

<h3>Further explanation</h3>

A whole number is one of the numbers set {0, 1, 2, 3, 4, ...}. They are a set of positive integers along with zero and don't include the fraction or decimal numbers.

We determine how many pairs of whole numbers have a sum of 40. Let us notice below.

(0, 40)
(1, 39)
(2, 38)
(3, 37)
(4, 36)
(5, 35)
(6, 34)
(7, 33)
(8, 32)
(9, 31)
(10, 30)
(11, 29)
(12, 28)
(13, 27)
(14, 26)
(15, 25)
(16, 24)
(17, 23)
(18, 22)
(19, 21)
(20, 20)

Hence, there are 21 pairs.

The next setting is a repeat pair. Remember, because the order in pairs does not have an effect so that $\boxed{ \ (a, b) \ is \ equal \ to \ (b, a) \ }$ , vice versa. Exactly like this:

(21, 19) ⇔ (19, 21), (22, 18) ⇔ (18, 22)

and so forth, until (39, 1) ⇔ (1, 39), (40, 0) ⇔ (0, 40)

Note, we can use the principle of finding many terms from the arithmetic sequence, even though they are not too many.

The general term of an arithmetic sequence (aₙ) with common difference d is $\boxed{ \ a_n = a_1 + (n - 1)d \ }$

Given:

The first term a₁ = 0
The common difference d = 1 (from 1 - 0, 2 - 1, etc.)
The last term aₙ = 20

How many terms (n)?

$\boxed{ \ a_n = a_1 + (n - 1)d \ }$

$\boxed{ \ 20 = 0 + (n - 1) \cdot 1 \ }$

$\boxed{ \ 20 = n - 1 \ }$

$\boxed{ \ 20 + 1 = n \ }$

We get $\boxed{ \ n = 21 \ }$ , i.e., whole numbers pairs that have a number of 40.
