Answer:
[tex]\frac{21}{40}n[/tex] + [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The important part to understand about this problem is that you need to find a common denominator. You can ONLY add two fractions if they have the same denominator. A way to change the denominator of a fraction is to multiply the numerator and denominator of the fraction by the same number.
So, You want to make the 2/5n and 1/8n to have the same denominator so you can add them. An easy rule of thumb is multiply the one of the fraction by the other fraction's denominator, so in this problem:
[tex]\frac{2 * 8}{5*8} n[/tex] and [tex]\frac{1*5}{8*5}n[/tex]
this comes out as
16/40n and 5/40n
NOW, they have the same denominator and you can add the numerators together to make it one happy fraction
[tex]\frac{16}{40} + \frac{5}{40} = \frac{16+5}{40} = \frac{21}{40}[/tex]
Then, for the 3/6, you can simplify this fraction into:
1/2
This is because if you divide the top and bottom of the fraction by 3 like so:
[tex]\frac{3/3}{6/3}[/tex] (Always make sure you do the same for the top as you do to the bottom)
This comes out as
[tex]\frac{1}{2}[/tex]
Then for the full equation:
[tex]\frac{21}{40} n + \frac{1}{2}[/tex]

Replace x in the equation with the given x values and solve for y:
3 + 2(4) = 11
3 + 2(5) = 13
3 + 2(9) = 21

Solve the System of equations x = -2 ; y= -3 .(show your work step by step).
x+2y = 4

Answer:
Determine the point of intersection by using substitution and solving for the variables.
Explanation:
Solving a system of equations imply we find the point of interception.
To do this, we must use substitution to find one variable, and use that value to determine the exact value of the other.
Here, we'll isolate

Answer:
W = 17
Step-by-step explanation:
Hi! Ok so the equation is: 24=2w-10
24=2w-10 First add =10 to each side
10+24= 2w +10 -10 the tens on the right cancel.
34=2w then divide each side by negative two
(34/2)=(2/2)w can be simplified to 17=w

35th term of the arithmetic sequence 203, 199, 195,...... is 67.
What is arithmetic sequence ?An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.
The given arithmetic sequence is,
203, 199, 195,......
In the sequence, the first time a = 203,
And common difference of the sequence d = -4
Formula for nth term of the sequence,
aₙ = a + (n-1) . d
To find 35th term of the sequence, substitute n= 35,
a₃₅ = 203 + (35-1).(-4)
= 203 + 34x-4
= 203 - 136
= 67

pls answer yessirrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
Answer:
150
Step-by-step explanation:
this first side is 6 by 5, (6 x 5 = 30) and 4 sides have these measurements so (30 x 4 this = 120) to find the surface area of all these sides.
The second type of side is 3 by 5, (3 x 5 = 15) and 2 sides have these measurements so we have to do (15 x 2 = 30) to find the surface area of all these sides.
Now that we have all the surface area of all the sides we have to add them up (30 + 120) the surface area of the rectangular prism is 150.

if f(1)= 10 and f(n)=f(n-1)+4 then find the value of f(5)
Answer:
f(5)=26
Step-by-step explanation:
hello :
f(n)=f(n-1)+4 means : f(n)-f(n-1)=4 (comon diference for arithm - sequence)
so : f(n) =f(1)+(n-1)×4
f(n) =10+(n-1)×4
f(n) = 4n+6

========================================================
Explanation:
The drawing is shown below.
Notice that 23 + 67 = 90, or you could say 90-67 = 23.
Use the tangent ratio to find x.
tan(angle) = opposite/adjacent
tan(23) = x/903
x = 903*tan(23)
x = 383.300759 approximately
x = 383.30
What is the range of the function y = e superscript 4 x y less-than 0 y greater-than 0 y less-than 4 y greater-than 4
The range of a function [tex]\rm y= e^4^x[/tex] is y>0; option second y > 0 is correct.
It is given that the function [tex]\rm y= e^4^x[/tex]
It is required to find the range of a function [tex]\rm y= e^4^x[/tex]
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function.
We have a function:
[tex]\rm y= e^4^x[/tex]
If we plot a graph of [tex]\rm y= e^4^x[/tex]:
When x = 0 then [tex]\rm y= e^4^\times^0[/tex] ⇒ 1
When x = 1 then [tex]\rm y= e^4^\times^1[/tex] ⇒ 54.598 and so on.
The graph will exponentially go up as shown in the picture because the 'e' is the positive value(e=2.718) and the power of negative or positive values is never be a negative result.
Thus, the range of a function [tex]\rm y= e^4^x[/tex] is y>0; option second y > 0 is correct.

The value which shows the true solution to the given logarithmic equation is 1.
What is the domain and range of the function?The domain of a function is defined as the set of all the possible input values that are valid for the given function.
The range of a function is defined as the set of all the possible output values that are valid for the given function.

Step-by-step explanation:
Given function:
[tex]\sf f[g(x)]=\dfrac{-6+23}{7x-16}[/tex]
The domain will be values of x that do NOT make the denominator zero:
[tex]\sf \implies 7x-16=0[/tex]
[tex]\sf \implies 7x=16[/tex]
[tex]\sf \implies x=\dfrac{16}{7}[/tex]
Therefore, the domain is [tex]\sf x\neq \dfrac{16}{7}[/tex] so
