75/1+15e^-0.4x=25 solve for x
Answer:
[tex]\frac{75}{1}+15e^-\cdot \:0.4x=25\quad :\quad x=-\frac{25}{3};\quad \ne \mathrm{True},\:e\ne \:0\quad \left(\mathrm{Decimal}:\quad x=-8.33333\dots \right)[/tex]
Step-by-step explanation:
[tex]\frac{75}{1}+15e^-\cdot \:0.4x=25[/tex]
[tex]\mathrm{Apply\:rule}\:\frac{a}{1}=a[/tex]
[tex]\frac{75}{1}=75[/tex]
[tex]75+15\cdot \:0.4e^-x=25[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:15\cdot \:0.4=6[/tex]
[tex]75+6e^-x=25[/tex]
[tex]\mathrm{Subtract\:}75\mathrm{\:from\:both\:sides}[/tex]
[tex]75+6e^-x-75=25-75[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]6e^-x=-50[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}6e^-;\quad \ne \mathrm{True}[/tex]
[tex]\frac{6e^-x}{6e^-}=\frac{-50}{6e^-};\quad \ne \mathrm{True}[/tex]
[tex]\mathrm{Simplify}[/tex]

Answer:
-11/8
Step-by-steexplanation:
Help! Best answer will get brainiest
Answer:
x=20
Step-by-step explanation:
Complementary means =90 degrees, so with that being said, you need to write the equation as follows:
2x+10+x+20=90
Then add like terms:
3x+30=90
Subtract 30 from both sides (30 and 90)
3x=60
Divide both sides by 3
x=20

What is the equation of the axis of symmetry?
Easy please help
Answer:
[tex]-\frac{b}{2a}[/tex] is the equation for axis of symmetry.
Step-by-step explanation:
b is the second part of the quadratic equation and a is the first part.
For example, [tex]2x^{2} +6x + 4[/tex]
a is 2 and b is 6.
Plug in those values into the equation and then you get the axis of symmetry.

While hiking, Sandra went up 120 meters. If Sandra started at 800 meters above sea
level, what is her elevation now?
The Answer:
If Sandra started at 800 meters and went up 120, the answer would be 920.
Step-by-step explanation:
First, simply add 800 meters, which is what she started with. Next, since she has gone up 120 meters since then, and the question is asking us what her elevation is NOW, you can add 800 + 120 to get 920. This question is solved by using addition.
Hope this helps!
A restaurant sells a coffee refill mug for $6.75. Each refill cost $.1.25. Last month, Keith spent $31.75 on a mug and the refills. How many refills did Keith purchase last month? Write and solve an equation to determine the number of refills, r, that Keith purchased.
Answer:

what is the slop of the line that contains the points (-2,7) and (2,3) ?
Answer:
The answer would be -1
Step-by-step explanation:
Slope = ∆y/∆x
= (y2- y1 )/(x2- x1)
y2=3
y1= 7
x2=2
x1= -2
= (3-7)/(2--2)
= -4/(2+2)
= -4/4
= -1
