Question

Horizontal number line with nine markings, Center mark is marked ten with a bold dot. Line to the right of ten is bolded. Right and left ends of line are arrows pointing outward.


Select one:


A. two fifths times p is greater than or equal to four

B. negative two fifths times p is less than or equal to four

C. negative two fifths times p is greater than or equal to four

D. two fifths times p is less than or equal to four

Answer 1

if you want a clearer picture

Answer 2

hmm what is that line saying anyway?
it has a solid ball, then goes from 10 to the right
what does that mean?

Answer 3

It means its greater than or equal to @jdoe0001

Answer 4

ok
let's see the given choices, to see which one might be
let's see C
\(\bf -\cfrac{2}{5}p\ge 4\implies -2p\ge5\cdot 4\implies -2p\ge 20
\\ \quad \\
-\cfrac{1}{2}\cdot -2p\ge-\cfrac{1}{2}\cdot 20\implies p{\color{blue}{ \le}}-10\)

so.... that says,
P is less than or equals to -10

so, that one is not it

so.. check the others, BD and A
see if you get \(\bf p \ge 10\)

Answer 5

you have no choice, you have to solve each one and see which gives \[x\geq 10\]

Answer 6

you do this by multiplying \(4\) by \(\frac{5}{2}\) for the first one
