Answer:

v=18, b=59. (18, 59).

Step-by-step explanation:

v+6b=372

4v+12b=780

-----------------

simplify 4v+12b=780 into v+3b=195,

v+6b=372

v+3b=195

---------------

-(v+6b)=-372

v+3b=195

---------------------

-v-6b=-372

v+3b=195

----------------

-3b=-177

3b=177

b=177/3

b=59

v+6(59)=372

v+354=372

v=372-354

v=18

please help. will give brainliest! review the table of values for function p(x). what is lim (x -14) p(x), if it exists? (table

Lubov Fominskaja [6]

Answer:

DNE

Step-by-step explanation:

The the given table, we have;

As x approaches -14 from the left, at x = -14.001, p(x) = 1.96

$\lim \limits _{x \to -14^{-}} p(x) = 1.96$

As x approaches -14 from the right, at x = -13.999, p(x) = 1.97

$\lim \limits _{x \to -14^{+}} p(x) = 1.97$

The value of p(x) when x = -14 is $\lim \limits _{x \to -14} p(x)$ = Undefined, or is not definable, therefore, p(x) Does Not Exist (DNE) when x = -14, and we have;

$\lim \limits _{x \to -14} p(x)$ Does Not Exist, DNE.
