First pick a value of
close to
. You should be fine with
.
The linear approximation of
at
is given by
where
is some fixed value close to
. You have
so
The actual value is closer to -0.9709, so the approximation is decent.
Answer:
<h3>
Solution (4, -12)</h3>
<em>None of the listed choices are a solution</em>
Step-by-step explanation:
y = 4x - 28
y = 1.5x - 18
Set the equations equal since both equal y
4x - 28 = 1.5x - 18
Subtract 1.5x from both sides
2.5x - 28 = -18
Add 28 to both sides
2.5x = 10
Divide both sides by 2.5
x = 4
---------------------
use x= 4 in either equation
y = 4x - 28
y = 4(4) - 28
y = 16 - 28
y = -12
--------------------
Solution (4, -12)
If you have to find x-intercept, then you have to equate y to 0. Thus,
when y=0, x+2·0=5 and x=5.
Point (5,0) is x-intercept.
