What are the solution

AleksandrR [38]

Answer:

Step-by-step explanation:

We can get two equations from the inequality:

$3x+2>9\\3x+2>-9$

We just need to simplify both equations to get our answers:

$3x+2>9\\3x>7\\x>\frac{7}{3}$

$3x+2>-9\\3x>-11\\x>\frac{-11}{3}$

The two answers we get are:

$x\frac{7}{3}$

Which is also B.

If R is between Q and S then QR+RS=QS

given
QR=x+4
RS=3x-1
and QS=27

x+4+3x-1=27
combine like terms
4x+3=27
minus 3 both sides
4x=24
divide both sides by 4
x=6

sub back
QR=x+4
QR=6+4
QR=10

RS=3x-1
RS=3(6)-1
RS=18-1
RS=17

x=6
QR=10
RS=17

Evaluate if m=1 and n=2 what’s 15m/n+1-m^2+n

Jobisdone [24]

$\\ \sf\longmapsto \dfrac{15m}{n}+1-m^2+n$

$\\ \sf\longmapsto \dfrac{15(1)}{2}+1-(1)^2+2$

$\\ \sf\longmapsto \dfrac{15}{2}+3-1$

$\\ \sf\longmapsto \dfrac{15}{2}+2$

$\\ \sf\longmapsto \dfrac{15+4}{2}$

$\\ \sf\longmapsto \dfrac{19}{2}$

Find a polynomial, which, when added to the polynomial 5x^2–3x–9, is equivalent to <br><br> x^2-5x+6

alexandr1967 [171]

So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9

wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2

then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x

-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15
