How you start the equation is by plugging
3
into both of the
x
's in the problem to make it:
f
(
3
)
=
3
(
3
)
−
4
Next, you multiply the
3
(
3
)
to get
9
and subtract
4
. So in the end, you leave the
f
(
3
)
and
9
−
4 is
5
, so the
y
in the equation is
5
.
The answer would be written as
f
(
3
)
=
5
Answer:
A line segment has two ends, and a line doesn't end.
Step-by-step explanation:
So,
We can re-write these statements in mathematical form.
Let h represent Holly and j represent Julia.
First equation:
Second equation:
This is our System of Simultaneous Linear Equations.
I'll solve.
Substitute

Subtract 35 from both sides
Multiply both sides by
j = 48
Substitute 48 for j in the first equation
h + 48 = 107
Subtract 48 from both sides
h = 59
Check
59 + 48 = 107
107 = 107 This checks.
59 = 35 +
59 = 35 + 24
59 = 59 This also checks.
Holly scored 59 points and Julia scored 48 points.

Step-by-step explanation:
Just answer it
Answer and Step-by-step explanation:
Simply multiply 3 by 5.
We do this because for every hour we run, we run 5 miles, and the person runs for 3 hours.
<u>So, the answer is 15 miles.</u>
