Answer:
19) x = number of people; y = cost
20) (people, cost) = (15, 120) and (25, 200)
21) the rate of change is $8 per person
22) y = 8x
23) $320
Step-by-step explanation:
19) The problem statement tells you x is the number of people and y is the cost.
__
20) Writing the pairs (people, cost), we have ...
(15, 120) and (25, 200)
__
21) The rate of change can be found from the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (200 -120)/(25 -15) = 80/10 = 8
The rate of change is $8 per person.
__
22) In point-slope form, the rule is ...
y -y1 = m(x -x1)
y -120 = 8(x -15)
y = 8x -120 +120
y = 8x
__
23) For x=40, y = 8(40) = 320
A party for 40 people will cost $320.

Step-by-step explanation:
4x +5 = 7x -22
5 = 3x -22
27 = 3x
x = 27/3
x = 9
4(9) + 5 = RS
36+ 5 = RS
RS = 41
Answer:
RS=41
Step-by-step explanation:
Because RT intersects the midpoint of QS, from doing some geometry we know that QRT and SRT are congruent triangles. Thus, RS=RQ because of cpctc
so, we can make the equation:
4x+5=7x-22
simplify
3x=27
x=9
now, plug that into 4x+5, and we get 36+5, or 41. RS=41

Given the following vectors in component form: r= (2,3) s= (5,-3) t= (-8,6) Check all expressions whose sum represents the same vector as (r+s)+t
Answers
Answer:
Step-by-step explanation:
< 7, 0 > + < - 8, 6 >
< 2, 3 > + < - 3, 3 >
< - 6, 9 > + < 5, - 3 >
If r= (2,3) s= (5,-3) t= (-8,6) then (7,0)+(-8,6) ,(2,3)+(-3,3) and (-6,9)+(5,-3) are equal to (r+s)+t
What is vector ?
Vector is a quantity with magnitude and direction .
Given vectors in component form are
r=(2,3) ,s=(5-3) , t =(-8,6)
We can calculate (r+s) as
(2,3)+(5,-3)
=(2+5,3-3)
=(7,0)
Now we can calculate (r+s)+t as
(7,0)+(-8,6)
(7-8,0+6)
(-1,6)
(a)
(0,7)+(-8,6)
=(-8,1)
Not equal to (r+s)+t
(b)
(7,0)+(-8,6)
=(-1,6)
equal to (r+s)+t
(c)
(2,3)+(-3,3)
=(-1,6)
equal to (r+s)+t
(d)
(2,3)+(3,-3)
=(5,0)
Not equal to (r+s)+t
(e)
(-6,9)+(5,-3)
=(-1,6)
equal to (r+s)+t
If r= (2,3) s= (5,-3) t= (-8,6) then (7,0)+(-8,6) ,(2,3)+(-3,3) and (-6,9)+(5,-3) are equal to (r+s)+t

A.
2 hours
B.
1 hr. 30 min
Answers
Answer:
the answer is a i believe
Step-by-step explanation:
The solution is Option A.
The total time it took to travel from the house to Gurnee Mills is given by the equation A = 2 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total time to travel from the house to Gurnee Mills be A
Now , the equation will be
The time it took to travel to Gurnee Mills without waiting = 1 hour
The waiting time before travel = 1 hour
So , the total time to travel from the house to Gurnee Mills A = time it took to travel to Gurnee Mills without waiting + waiting time before travel
Substituting the values in the equation , we get
The total time to travel from the house to Gurnee Mills A = 1 + 1
On simplifying the equation , we get
The total time to travel from the house to Gurnee Mills A = 2 hours
Therefore , the value of A is 2 hours
Hence , the the total time is 2 hours

Amanda's parents had a birthday dinner for her at Sushi Yama restaurant. The bill came to $74 before the tip. They left an 18% tip. What was the total cost of Amanda's birthday dinner?
Answers
Answer:
$87.32Step-by-step explanation:
Step one:
given data
we are told that the initial bill is $74
thereafter they gave a tip worth 18% of the bill
let us compute what 18% of $74 will amount to
Step two:
=18/100*74
=0.18*74
=$13.32
The added expenses is $13.32
Hence the total cost is
the initial bill plus the tip
=74+13.32
=$87.32

x^(2)+16x+28=0 complete the square
Answers
Answer:
(x + 8)² = 36
Step-by-step explanation:
When you are trying to complete the square and the equation already has a constant, you add or subtract that value to the other side of the equation so you can cancel it out.
x² + 16x + 28 = 0
x² + 16x + 28 - 28 = 0 -28
x² + 16x = -28
Now, you find ([tex]\frac{b}{2}[/tex])² (divide b by 2 and raise the quotient to the second power). Half of 16 is 8, and 8² is 64. Add 64 to both sides.
x² + 16x + 64 = -28 + 64
x² + 16x + 64 = 36
Now, you just factor the equation on the left. To factor it, you will always use the number you got to make the constant, which in this case is 8.
(x + 8)² = 36

Answers
Answer:
$201.99
Step-by-step explanation:
Given that:
Amount held on Monday = $61.72
Amount withdrawn on Tuesday = $57.00
Amount deposited on Thursday = $197.27
Final balance :
Amount held on Monday - Amount withdrawn on Tuesday + Amount deposited on Thursday
$61.72 - $57.00 + $197.27 = $201.99
Hence, final balance = $201.99
Kayla is give a monthly allowance. She puts 40% of the money directly into her savings account. She spends $15 at the movies with her friends. At the end of the month, she has $3 left. How much is her monthly allowance?

This is because if she has put 40% in to savings she has 60% left. This 60% is 15 + 3 (the money she spent at the movies and the money she has left) = £18
So 60% : £18
10% : £3 (divide by 6)

number of boys and girls are in the class are in the ratio of 7 : 5 the number of boys is 8 more than the number of girls what is a total class strength?
Answers
Answer:
Step-by-step explanation:
Given ratio of boys and girls in the class =7:5
No of boys is 8more than the girls
So
Let no of boys in the class =7x
No of girls in the class=5x
7x=5x+8
2x=8
X=8/2
X=4.
Total strength =no of boys + no of girls
=7x+5x
=7×4+5×4
= 28+20
=48.
Total strength in the class is 48.
Answer:
Total class strength = 48
Step-by-step explanation:
Boys : Girls = 7 : 5
Number of boys = 7x
Number of girls = 5x
7x - 5x = 8
2x = 8
x = 8/2
x = 4
Total strength = 7x + 5x = 12x = 12*4 = 48
