Answer:

x
intercept:
x
=
−

3
y
intercept:
y
=
5
Explanation:
For a linear graph, the quickest way to sketch the function is to determine the
x
and
y
intercepts and draw a line between the two: this line is our graph.
Let's calculate the
y
intercept first:
With any function,
y
intercepts where
x
=
0
.
Therefore, substituting
x
=
0
into the equation, we get:
y
=
3
⋅
0
+
5
y
=
5
Therefore, the
y
intercept cuts through the point (0,5)
Let's calculate the
x
intercept next:
Recall that with any function:
y
intercepts where
x
=
0
.
The opposite is also true: with any function
x
intercepts where
y
=
0
.
If we substitute
y
=
0
, we get:
0
=
3
x
+
5
Let's now rearrange and solve for
x
to calculate the
x
intercept.
−
5
=
3
x
−
5
3
=
x
Therefore, the
x
intercept cuts through the point
(
−
5
3
,
0
)
.
Now we have both the
x
and
y
intercepts, all we have to do is essentially plot both intercepts on a set of axis and draw a line between them
The graph of the function

What's 1/3 of 12?
Mulitply 1/3 times 12 = 4
Nita uses 4 eggs.
Answer:
A. 4
B. 8
Step-by-step explanation:
The correct answer is C because the problem showed ( x + 20 ) and ( x + 8 ) two times in the problem. That explains why there is a two outside of the parentheses.
Hope I helped! :)
Answer:
9
Step-by-step explanation:
9.45 is rounded down to 9 because the number must reach half to round up. To round up to 10, it must be 9.5. hope this helps
