Step-by-step explanation:
X^4-33x^2+200=0 (factor that out)
<span>x^4-33x^2+200 -----> (x^2-8)(x^2-25)
</span>
new equation:
x^2-8=0 x^2-25=0 (solve for x for both equations)
x^2=8 x^2 =25
the x's are still squared so you have the square root both sides of the equations to get rid of the ^2:
x^2=8 x^2=25
x=
x=5
Do you have any answer choices
Answer:
y = x + 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 5y = 3x + 12 into this form
divide all terms by 5
y = x + ← in slope-intercept form
with slope m =
• Parallel lines have equal slopes, hence
y = x + 2 ← equation of parallel line
Answer:
Let n be the number of nights spent.
Since the first two nights are each $75, if n≤2, the $75n
Since each additional night after that, is $50, if n>2, such a client pays $150 for the first 2 nights and $50 for each of the other n-2 nights for a total of $[150+50(n-2)] = $(50n+50)
So the function for the cost is
C(n) = 75n for n ≤ 2
C(n) = 50n+50 for n > 2
