!pic attached!Earl and Ray run competing carpet-cleaning services. Earl charges $50 for a house call and $40 per carpet cleaned. Ray charges the
same amount per carpet cleaned, but his total cost is always $30 less than Earl's. Which equation expresses the total cost, t, for Ray to
clean as a function of carpets cleaned, c?
Answer:
t= 20+40c
Step-by-step explanation:
Given that Ray's total cost is always $30 less than Earl's and they charge the same amount per carpet cleaned, the difference is in the amount charged for a house call and to find that amount you have to subtract 30 from the amount Earl's charges:
50-30=20
This means that Ray charges $20 for a house call and $40 per carpet cleaned. According to this, the equation would indicate that the total cost for Ray is equal to the amount he charges for a house call plus the price per carpet cleaned for the number of carpets cleaned, which would be:
t= 20+40c, where:
t is the total cost
c is the number of carpets cleaned
what are the expressions that are equivalent to 2x + 3x + 8 - 3x - 2
Answers that equivalent to the expression 2x+3x+8-3x-2 would be the choices A and C. If you notice, in choice A, you have just combined all the like terms which results in 2x+6 and in Choice C, you have combined all your constants and the the two terms 2x and 3x resulting in 5x-3x+6 which all remain equivalent to he original given expression

A horse weight is 700lb and needs medication that is 10mg per 100kg what is the horses weight in kg?
Answer:
315 kg
Step-by-step explanation:
to find the weight of the horse:
1lb = 0.45 kg (rounded the .45)
(700lb) x (0.45)= 315
to find how much medicine they need:
315/10= 31.5
the horse wieghs 315kg meaning that they would need 31.5mg of medication.

There are 50 U.S states. seven twenty-fifths of the state share a land border with Canada or Mexio of those 2/7 share a border with mexio how many states share a border with Canada?????
thirteen states share a border w canada
There are 20 states that share the border with Canada.
What is subtraction?Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.
Given:
There are 50 U.S. states.
Seven twenty-fifths of the state share a land border with Canada or Mexico.
That means,
7[tex]\frac{20}{5}[/tex]
= 7 x 4
= 28
a number of 28 states share the border with Canada or Mexico.
Of those 2/7 share a border with Mexico,
that means, the number of,
= 28 - 28 x 2/7
= 28 - (4 x 2)
= 28 - 8
= 20 states share the border with Mexico.
Therefore, the required number is 20.

Given:
The parent function is
[tex]f(x)=x^2[/tex]
The graphs of f(x) and g(x) are given.
To find:
The function g(x).
Solution:
From the given graph it is clear that the graph of f(x) is reflected over the x-axis and shifted 3 units down to get the graph of g(x).
The translation is defined as
[tex]g(x)=kf(x+a)+b[/tex] .... (1)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k. If k<0, then the graph of f(x) reflected over the x-axis.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
From the given graph it is clear that the graph of f(x) is reflected over the x-axis and shifted 3 units down to get the graph of g(x). So, k=-1, a=0 and b=-3.
[tex]g(x)=(-1)f(x+0)+(-3)[/tex]
[tex]g(x)=-f(x)-3[/tex]
[tex]g(x)=-x^2-3[/tex] [tex][\because f(x)=x^2][/tex]
Therefore, the required function is [tex]g(x)=-x^2-3[/tex]. So, the correct option is B.
