The table below represents a linear function f(x) and the equation represents a function g(x): (See pic)
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answer:
Step-by-step explanation:
A.
slope of f(x) remember that m=rise /run and see how you get from point (0,0) to (1,3) for example
m= rise 3/ run 1= 3
slope of g(x) you find by comparing it to y=mx+b wher m is slope and b is intercept so g(x) slope is m = 7
Slope of f(x) is 3 and slope of g(x) is 7 so g(x) go upward faster.
B.
again compare g(x) =7x+2 with y=mx+b where b is the y-intercept
g(x) has y-intercept at (0,2)
we can see from the table that at x=0 the y-intecept is 0
f(x) has y-intercept at (0, 0)
g(x) has a greater y-intercept point

69 athletes are running a race. A gold medal is to be given to the winner, a silver medal is to be
given to the second-place finisher, and a bronze medal is to be given to the third-place finisher.
Assume that there are no ties. In how many possible ways can the 3 medals be distributed?
Answer:
The order of finishing is important here, therefore you use permutations rather than combinations. Athlete A winning a gold medal, athlete B silver, and athlete C bronze is not the same as athlete A bronze, athlete B silver and athlete C gold for instance
69P3 = 69! / (69 -3!)

Remember that whole numbers that are next to each other, for example, 2 and 3, or 43, 44, and 45 are called consecutive numbers.
If n is the smallest of three consecutive integers, write an expression for the largest number.
Answer:
n +2
Step-by-step explanation:
If three numbers are consecutive, the 2nd number would be one more than the 1st number, and the 3rd number would be one more than the 2nd number.
Since the smallest number is n,
2nd consecutive number= n +1
3rd consecutive number
= n +1 +1
= n +2
Thus, the expression for the largest number is n +2.
Let's check!
If the smallest of the three consecutive number is 1, the 3rd consecutive number would be 3.
3rd consecutive number
= n +2
= 1 +2
= 3 (✓)
Thus, the expression is correct.
Which point-slope equation represents a line that passes through (3,-2) with a slope of -4/5?
y-3=(x+2)
y-2 = (2x - 3)
y+2=- (– 3)
y + 3 = 4(x + 2)
Answer:
y + 2 = -4/5 (x - 3)
Step-by-step explanation:
y - y1 = m (x - x1). Put in your points for y1 and x1, and always remember to flip your signs.
unfortunately, I don't know why that isn't one of your answers, so sticking with the positive 2 I would choose y+2=- (- 3) if I were you. Looks like the -4/5 disappeared somehow?
Hope this helps

Find the solution to the system -6×+8y=12 and -3×+4y=6
Answer:
hey can you please answer my biology question
Step-by-step explanation:
pleaseeeeeeeee
i really need
help.
Answer:
y = 3/4x + 3/2
x = 4/3y - 2
There are infinitely many solutions.
__________
To prove these equation are the same
multiply every quantity by 2 using the multiplication property of equality.
[ -6x + 8y = 12 ] = 2 [ -3x + 4y = 6 ]
2(-3x) + 2(4y) = 2(6) = 2(-3x) + 2(-4y) - 2(6) = -6x + 8y = 12 = -6x + 8y - 12
2(-3x) + 2(4y) - 2(6) = -6x + 8y - 12
-6x + 8y - 12 = -6x + 8y - 12
+6x -8y +12 +6x -8y + 12
(The general property of equality, what you do to one side, you must do to the other)
0 = 0 [always true]

A student has a class with four tests, each worth 100 points, and has earned these
scores on the first three tests: 75, 74, 71. What is her average now? What score must
she earn on the fourth test to get a B (80) in the class?
The student's average is 73.33.
The score on the fourth test to have a B is 100.
What is the average?The average can be determined by adding the scores and dividing it by the total scores.
Average on the first three scores : (75 + 71 + 74) / 3
220 / 3 = 73.33
Score on the fourth test to get an 80: 80 = (220 + x) / 4
80 x 4 = 220 + x
320 = 220 + x
x = 320 - 220
x = 100

The perimeter of a triangle is 17x-5 units. One side is 3.x + 5 units and another is 8x-3 units. How many units long is the third side?
Answer:
C = 6x - 7 units
Step-by-step explanation:
Let the three sides of the triangle = A, B, and C respectively.
Given the following data;
Perimeter of triangle, P = 17x-5 units
Side A = 3x+5 units
Side B = 8x-3 units
To find side C?
The perimeter of a triangle is given by the addition of all its three (3) sides.
Mathematically, the perimeter of a triangle is given by the formula;
P = A + B + C
Making "C" the subject of formula, we have;
C = P - A - B
Substituting into the equation, we have
C = 17x - 5 - (3x + 5) - (8x - 3)
C = 17x - 5 - 3x - 5 - 8x + 3
Collecting the like terms, we have;
C = 17x - 3x - 8x - 5 - 5 + 3
C = 6x - 7 units
Therefore, the third side is 6x - 7 units long.

Answer:
PV= $40,279.36
Step-by-step explanation:
Giving the following information:
Number of periods= 8*12= 96 months
Interest rate= 0.039/12= 0.00325
Future value (PV)= $55,000
To calculate the initial investment, we need to use the following formula:
PV= FV/(1+i)^n
PV= 55,000 / (1.00325^96)
PV= $40,279.36
