Step-by-step explanation:
C. i) y = 23,000(1 - 0.15)^t
ii) y = 23,000(1 - 0.15)^t
y = 23,000 x 0.85^4
y = 23,000 x 0.52200625
y = $12,006.14
y = $12,006. when rounded to the nearest dollar

Answer:
x = 3, y = 4
Step-by-step explanation:
First, set the first equation equal to x. Note the equal sign, what you do to one side, you do to the other.
Subtract y from both sides of the equation:
x + y = 7
x + y (-y) = 7 (-y)
x = 7 - y
Next, plug in 7 - y for x in the second equation:
2x + y = 10
2(7 - y) + y = 10
Simplify. First, distribute 2 to all terms within the parenthesis:
2(7 - y) = (2 * 7) + (2 * -y) = 14 - 2y
Next, combine like terms. Like terms are terms with the same amount of the same variables:
14 - 2y + y = 10
14 (-2y + y) = 10
14 - y = 10
Isolate the variable, y. First, subtract 14 from both sides of the equation:
-y + 14 (-14) = 10 (-14)
-y = 10 - 14
-y = -4
Next, isolate the variable, y, by dividing -1 from both sides of the equation:
(-y)/-1 = (-4)/-1
y = -4/-1 = 4
Next, plug in 4 for y in one fo the given equations:
x + y = 7
x + (4) = 7
Isolate the variable, x. Subtract 4 from both sides of the equation:
x + 4 (-4) = 7 (-4)
x = 7 - 4
x = 3
x = 3, y = 4

Answer:
the x- coordinate of the turning point is - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Given
y = x² + bx + c with y- intercept = (0, - 14 ) then c = - 14 , so
y = x² + bx - 14
To find b substitute (2, 0 ) into the equation
0 = 2² + 2b - 14
0 = 4 + 2b - 14
0 = - 10 + 2b ( add 10 to both sides )
10 = 2b ( divide both sides by 2 )
5 = b , then
y = x² + 5x - 14
Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the turning point is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 5x - 14 ← is in standard form
with a = 1 and b = 5 , then
x- coordinate of turning point = - [tex]\frac{5}{2}[/tex]

Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles how many red marbles does it contain
Answers
If a bag has 30 orange marbles then that means it has 42 red marbles
Step-by-step explanation:
If there are 7 red marbles for every 5 orange marbles then what you would do is.
30/5=6
6*7=42
Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles Then the bag contains 42 red marbles.
In the problem, we are given that each bag of marbles contains 7 red marbles for every 5 orange marbles. We need to find the number of red marbles when there are 30 orange marbles in the bag.
Let's represent the number of red marbles as R and the number of orange marbles as O.
According to the information provided, we have the following relationship:
R / O = 7 / 5
Now, we are given that the number of orange marbles (O) in the bag is 30. We can substitute this value into the equation:
R / 30 = 7 / 5
To find the number of red marbles (R), we can cross-multiple
R = (7 / 5) * 30
R = 42
Therefore, the bag contains 42 red marbles.
In summary, we used the given ratio of red to orange marbles in the bag to set up a proportion and then solved for the number of red marbles when the number of orange marbles was known. This allowed us to find that there are 42 red marbles in the bag.

Write an equation of the line (4,3) and (9,-2)
Answers
Answer:
y= -x + 7
Step-by-step explanation:
to get the equation of a line is y=mx+b
the slope, m, would be calculated (y1-y2)/(x1-x2)
thus we would substitute in (3--2)/(4-9)
which simplifies to 5/-5
or -1
now we know that m= -1
to solve for b we have to put the equation into point-slope form which is
y-y1= m(x-x1)
this would be y-3 = -(x-4)
y-3 = -x+4
y= -x+7
