Solve this question. a/7-3<0

Mathematics
1 answer:
valkas [14]3 years ago
7 0

Answer:

\boxed{\sf{a

Step-by-step explanation:

You only need to isolate the term a to solve this problem.

Add by 3 from both sides.

\sf{\dfrac{a}{7}-3+3

Solve.

0+3=3

a/7<3

Multiply by 7 from both sides.

\sf{\dfrac{7a}{7}

Solve.

3*7=21

<u>a<21</u>

As a result, the solution is a<21, which is our answer.

The minimum value of f(x) = x3 – 3x2 – 9x + 2 on the interval [–4, 0] is
garri49 [273]

Answer:

-74

Step-by-step explanation:

Graph the function. See attached picture. Between the interval where -4 > x < 0, the graph rises up to a peak and descends back down when x = 0. This means the minimum value will be where x = -4.

Substitute x = -4 into the equation.

f(-4) = (-4)^3 -3(-4)^2 - 9(-4) + 2

f(-4) = -64 -3(16) +36 + 2

f(-4) = -64 - 48 + 36 + 2

f(-4) = -74

Prove that any number n of the form abcabc, where a, b, and c are decimal digits, is divisible by 7, 11 and 13.
vfiekz [6]

We can factorize abcabc as

abcabc = abc000 + abc

abcabc = abc (1000 + 1)

abcabc = abc × 1001

abcabc = abc × 7 × 11 × 13

so naturally each of 7, 11, and 13 must divide abcabc.
