r s + 14s when r=6 and s=1/4
Answers
Explanation:
Basically you just change the letter for the number since R equals 6 then in the equation it would be 6 instead of R. Then for S, S would equal 1÷4 which equals 0.25. Then you plug in the numbers into your equation so look something like this 6 x 0.25 + 14(0.25) and all that together equals 5.
Hope this helped :)

Write an explicit formula that represents the sequence defined by the following
recursive formula:
a1= -1 and an = an-1 – 6
Answers
Answer:
an = -6n + 5.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 = -1 and common difference d = -6
an = a1 + d(n-1)
an = -1 + -6(n - 1)
an = -1 -6n + 6
an = -6n + 5.
The equation for line j can be written as y = 2x + 8. Another line k is perpendicular

Answers
Answer:
Solution given:
equation of line j is:
y=2x+8
comparing above equation with y=mx+c
we get
m=2
let slope of another line k be M
since lines are perpendicular
their product is -1
so
m *M=-1
2M=-1
M=-½
since it passes from (6,-6)
we have
(y-y1)=M(x-x1)
(y+6)=-½(x-6)
2y+12=-x+6
x+2y+12-6=0
x+2y+6=0 is a required equation of line k.
Answer:
[tex] \displaystyle y = - \frac{1}{2} x - 3[/tex]
Step-by-step explanation:
we are given that,
[tex] \displaystyle E _{ j}: y = 2x + 8[/tex]
and it's perpendicular to [tex]E_k[/tex]
since [tex]E_k[/tex] is perpendicular to [tex]E_j[/tex] the slope of the equation of k has to be -½
because we know that
[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{m}[/tex]
we are also given a point where the perpendicular line passes as we got the slope and a point we can consider using point-slope form of linear equation to figure out the perpendicular line
remember the point slope form
[tex] \displaystyle y - y_{1} = m(x - x_{1})[/tex]
we got that, y1=-6,x1=6 and m=-½ thus,
substitute:
[tex] \displaystyle y - ( - 6)= - \frac{1}{2} (x - 6)[/tex]
remove parentheses:
[tex] \displaystyle y + 6= - \frac{1}{2} (x - 6)[/tex]
distribute:
[tex] \displaystyle y + 6= - \frac{1}{2} x + 3[/tex]
cancel 6 from both sides:
[tex] \displaystyle y = - \frac{1}{2} x - 3[/tex]
hence, the equation of line k is y=-½x-3

UV = 9 ft
VW = 6 ft
WU = 5 ft
Step-by-step explanation:
The perimeter of a figure can be represented as the sum of lengths of all of its sides. In this case we can write:
P = UV + VW + WU
Now, we can substitute the values which we have:
20 = 4x + 1 + 8 - x + 2x + 1
We can combine like terms...
20 = 5x + 10
5x = 10
x = 2
Since UV is represented by 4x + 1, we can substitute in x to find its length.
UV = 4x + 1
UV = 4(2) + 1
UV = 6 + 1
UV = 9
We can do the same for the other two sides:
VW = 8 - x
VW = 8 - 2
VW = 6
WU = 2x + 1
WU = 2(2) + 1
WU = 4 + 1
WU = 5

The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coordinates. y = f(x) y = g(x) If g(x) = k f(x), what is the value of k? I am not sure how to do this. k = -3
Answers
Answer:
k = -3
Step-by-step explanation:
f(x) = -2x+1
g(x) = 6x - 3
=> g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3
The value of k for the given function will be k = -3.
What is a function?In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. A function can be thought of as a machine that takes an input, performs a certain operation on it, and produces an output.
Formally, a function is defined as a set of ordered pairs (x, y) such that each value of x is associated with exactly one value of y. The set of all possible inputs to a function is called its domain, while the set of all possible outputs is called its range.
The given functions are,
f(x) = -2x+1
g(x) = 6x - 3
The value of k will be calculated as,
g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
k= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3

Given data
Sales Tax= 8%
Cost of shirt= $36
Cost of shoe= $25
Total cost= 36+25
Total=$61
Let us find the amount of the Tax
=8/100*61

=$4.88
Hence the amount paid is
=61+4.88
=$65.88
It takes 180 ml of fertiliser to treat 36 m² of lawn.

Answer:
200 ml of fertilizer
Step-by-step explanation:
Create a proportion where x is the amount of fertilizer needed for an area of 40 m²
[tex]\frac{180}{36}[/tex] = [tex]\frac{x}{40}[/tex]
Cross multiply and solve for x:
