Answer:
Step-by-step explanation:
because it's an absolute value inequality, there are two inequalities to solve
3x+3 ≤ 9 and 3x+3 ≥ -9, now we solve them separately
x ≤ 3 and x ≥ -4, which is -4 ≤ x ≤ 3
so it says 6 times as old as June
so that would be 6x
then it said the sum so that's addition is no less than so that's subtraction
so it would be
X because we June's father age
so x times 6 > 77
Answer:
Step-by-step explanation:
Hi there!
Slope-intercept form: 
where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x is 0)
<u>1) Plug in the slope (</u><u><em>m</em></u><u>)</u>
We're given that the slope is 
. In , replace <em>m</em> with :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
We're given the point (-9,4). Plug this point into the equation as 
and solve for <em>b</em>:
Subtract 
from both sides to isolate <em>b</em>:
Therefore, the y-intercept is . Plug this back into as <em>b</em>:
I hope this helps!

Answer:
Hsu makes $35,950.50 and Alkena makes $48,418.50
Step-by-step explanation:
Create a system of equations, where h is the amount Hsu makes and a is the amount Alkena makes:
a + h = 84,369
a = h + 12,468
Solve by substitution by plugging in h + 12,468 as a:
h + 12,468 + h = 84,369
2h + 12,468 = 84,369
2h = 71,901
h = 35,950.50
Plug this into the equation, a = h + 12,468 , to solve for a
a = 35,950.50 + 12,468
a = 48,418.50
So, Hsu makes $35,950.50 and Alkena makes $48,418.50
