Answers may vary depending on the person reading the graph.
It is hard to tell what they think crosses nicely.
For example, I decided that the graph crossed nicely at the following points:



Step-by-step explanation:
I see that the graph crosses at
,
, and
.
The equation
tells us the
-intercept is
since when
we have
.
The
-intercept for our graph is
. Therefore,
.
So far we have the equation:
.
Let's enter the other points creating a system of linear equations to solve:


Let's simplify:


Let's subtract 3 on both sides:


I choose to solve the system by elimination.
Let's multiply the top equation by -3:


Now adding the equations results in:

Divide both sides by 24:

Now using one of the equations we can find
:
with 


Add 13/6 on both sides:



Divide both sides by 2:


So we have the equation:

Let's evaluate
now:




Answer:
5% of 800 is 40.
Step-by-step explanation:
5 percent * 800 =
(5:100)* 800 =
(5* 800):100 =
4000:100 = 40

Step-by-step explanation:
b.3n/2 = 7/2
6n = 14
n = 2 1/3
c.-x/2 + 6 = -13/4
-x/2 = -37/4
-4x = -74
x = 18 1/2
d.3x/10 = 2/5
15x = 20
x = 1 1/3
e.x/10 = -20/3
3x = -200
x = -66 2/3
f.269x/56 = 10
269x = 560
x = 2 22/269
Answer:
Simplifying
5x + x = 54
Combine like terms: 5x + x = 6x
6x = 54
Solving
6x = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '6'.
x = 9
Simplifying
x = 9
