Answer:
Step-by-step explanation:
Approximate distance between San Francisco and New York = 2903 miles
Number of family members = 4
Approximate distance to be covered by each member per day = [tex]\frac{2903}{4}[/tex] = [tex]725\frac{3}{4}[/tex] miles
Number of days to drive = 6 days
Total distance to be covered by each member each day = [tex]\frac{2903}{4}\times \frac{1}{6}[/tex]
= [tex]\frac{2903}{24}[/tex]
= [tex]120\frac{23}{24}[/tex] miles
Therefore, each family member has to drive the car for 120 miles per day approximately.
23 miles remaining will be covered by any one of the family members on the last day.
Each set of ordered pairs represents a function. Which set of ordered pairs would represent a function if the values of the x-coordinates and the values of the y-coordinates were
reversed?
O ((1,1). (2, 1), (3,1),(4,1);
O {(1,2), (2, 2).(3.3), (4,3)}
O {(1,4),(2,3), (3,1),(4,3)}
O [(1.2).(2,3), (3,4),(4.5))
Answer:
[(1.2).(2,3), (3,4),(4.5))
Step-by-step explanation:
once reversed, no x-values repeat therefore these ordered pairs would represent a function.
hope this helped!
The last set of ordered pairs, [tex]\{(1.2),(2,3), (3,4),(4.5)\}[/tex], would still be a function even if its x- and y-coordinates where reversed.
Reversing the x- and y-coordinates is like finding the inverse relation.
An inverse relation will be a function if the original function were one-to-one. The only set of ordered pairs that satisfies this condition is
[tex]\{(1.2),(2,3), (3,4),(4.5)\}[/tex]
The other options are many-to-one relations. On reversing their x- and y-coordinates, they each become one-to-many relations. All functions are either one-to-one, or many-to-one.
So, the answer is the last set of ordered pairs [tex]\{(1.2),(2,3), (3,4),(4.5)\}[/tex]

A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per text message received. Using s to represent the number of text messages sent in one month and r to represent the number of text messages received in one month, the following equation can be used to calculate the total monthly cost, c:
c = 39.95 + 0.15(s + r)
If it is known that the total monthly cost is $53.45 and 63 text messages were received, solve for s, the total number of text messages sent.
Answer:
c= 39.95 +0.15 (s + r) (take the 63 received and plug it in for r and 53.45 in for c then solve)
53.45= 39.95 +0.15 (s +63) (use the distributive property)
53.45 = 39.95 + 0.15s + 9.45 (combine like terms on the right side)
53.45 = 49.40 +0.15s (subtract 49.40 from both sides)
4.05 = 0.15s (divide both sides by 0.15 so isolate s)
s= 27 (how many text messages were sent)

find the slope of the line passing through the given points
Answer:
-5/6
Step-by-step explanation:
Slope= y2-y1/x2-x1
Answer:
The slope is -5/6
Step-by-step explanation:
You can use the method rise over run and count how many squares it takes to go from the y coordinate 4 to the y coordinate -1, which is -5. You can then count how many squares you need to get from the point -3 to 3 which is 6. Or you can use the formula to find slope, (y2-y1)/(x2-x1) and plug in you numbers.

Graphs:The set of ordered pairings (display style [tex](x,y)[/tex]) of a function (display style [tex]f(x)=y[/tex]) in mathematics is known as the graph of that function. These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the typical case where "display style [tex]x[/tex]" and "display style [tex]f(x)[/tex]" are real values.Graph equations:Equations with graphs as the unknowns are known as graph equations in graph theory. The concept of isomorphism is one of the key issues in graph theory.

Mr.Chang has a class of 18 students. He can spend $21 on each student to buy math supplies for the year. He first buys all of his students calculators, which cost a total of 170.64. After buying the calculators, how much does he have left to spend on each student
Answer:
572557486637778886367828766664728274747447378328288273
Answer: $11.52 left for each student
Step-by-step explanation:
First, divide the total amount of money spent by the total amount of students. 170.64/18. You will get $9.48. So, that means that so far Mr. Chang has spent $9.48 on each student. Then, just subtract $9.48 from $21 (which is the total amount he is willing to spend on each student. You should get $11.52. So, Mr. Chang has $11.52 left to spend on each student. Hope this helps!

Equation of a Straight Line
2.2 Solve 3x-y-9 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3x-y-9 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 9/-1 so this line "cuts" the y axis at y=-9.00000
y-intercept = 9/-1 = -9.00000
Calculate the X-Intercept :
When y = 0 the value of x is 3/1 Our line therefore "cuts" the x axis at x= 3.00000
x-intercept = 9/3 = 3
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -9.000 and for x=2.000, the value of y is -3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -3.000 - (-9.000) = 6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 3
Geometric figure: Straight Line
Slope = 3
x-intercept = 9/3 = 3
y-intercept = 9/-1 = -9.00000

Answer: choices for the number in hundreds place = 7 , 8, 9,0
Step-by-step explanation:
Given: Dinesh wrote a number greater than 4699 and less than 5100.
Numbers greater than 4699 = 4700, 4701,.....
Numbers less than 5100 = 5099, 5098 , .....
From 4700 to 5099 , the possible values for hundreds place = 7 , 8, 9,0
So, the choices for the number in hundreds place = 7 , 8, 9,0

Answer:
The number of children = x = 173
The number of Adults = y = 201
Step-by-step explanation:
Let the number of children = x
The number of Adults = y
Charge per child = $3
Charge per Adult = $5
Total number of tickets sold = 374
Amount raised = $1524
System of Equations
x + y = 374..... Equation 1
x = 374 - y
3x + 5y = 1524....Equation 2
We solve this question using substitution method
We substitute 374 - y for x in Equation 1
3(374 - y) + 5y = 1524
1122 - 3y + 5y = 1524
- 3y + 5y = 1524 - 1122
2y = 402
y = 402/2
y = 201
Solving for x
x = 374 - y
x = 374 - 201
x = 173
Hence:
The number of children = x = 173
The number of Adults = y = 201
