Numbers are x and y
x is 5 more than y
x=5+y
product is -3
xy=-3
solve
sub 5+y for x since x=5+y
(5+y)y=-3
5y+y^2=-3
add 3 to both sides
y^2+5y+3=0
use quadratic formula where
ay^2+by+c=0
y=
a=1
b=5
c=3
y=
y=
y=
y=
or
the second number is 5 more or 10/2 more
add 10/2 to each
x=
or
the numbers are
and
or
and
aprox
the numbers are
-0.697224 and 5.967224 or
-4.302775 and 0.697224
That’s the answer for you’re question
Answer:
Two dotted lines, one solid line
Step-by-step explanation:
The graph of the system of inequalities
will have two dotted lines, one solid line.
To plot the solution set to the inequality with signs < or >, we need to plot the dotted line (because the points of this line are not the solutions to the inequality).
To plot the solution set to the inequality with signs ≤ or ≥, we need to plot the solidd line (because the points of this line are the solutions to the inequality).
The system above has two inequalities with signs < and > and one inequality with sign ≥, so there will be two dotted lines, one solid line.
The correct answers will be A. The ninth odd number. B.O(8) + 2 and D.17.
I did this too and those were the right answers!
I hope this helps! :>
Answer:
Step-by-step explanation:
W + 6=.75
-6 -6
W= -5.25
W + 14 / 4
-5.25 + 14 / 4 = -1.75
