Answer:
y = 2,000(0.94)x
Step-by-step explanation:
f(x) = P (1 + r) ^x
P = 2000
r = -0.06
f(x) = 2000 (1 - 0.06)^x
= 2000 (0.94)^x

Express the ratio as a fraction in simplest form. 10 yards to 10 feet
Answer:
The ratio is 3:1
Step-by-step explanation:
[tex]\frac{10 yards}{10 feet}[/tex]
We know, 1 yard is equal to 3 feet
So, [tex]\frac{10 yards X 3}{10 feet}[/tex] is equal to [tex]\frac{30 feet}{10 feet}[/tex] is equal to 3:1

Light bulbs cost £3.40 each.
Yasmin buys as many as she can with £30.
How much change should she get?
Give your answer in pounds, £.
======================================================
Work Shown:
x = number of light bulbs
3.40x = total cost to buy x light bulbs, cost is in pounds
3.40x = 30
x = 30/(3.40)
x = 8.823529 approximately
Rounding down, we get 8
Note that,
3.40*8 = 27.20 pounds which is under budget3.40*9 = 30.60 pounds which is over budgetTherefore, the highest number of bulbs that can be bought is 8.
The change given will be 30-27.20 = 2.80 pounds

t midnight, a candle was lit. At 15 minutes past midnight, the candle was 4 inches tall, and you notice that it burns at a rate of 0.75 inches per hour.
(a)Write the point–slope form of the function that gives the height of the candle, h, in inches, as a function of time, t, in minutes past midnight, as the candle burns.
(b)When is the candle 1 inch tall?
Answer:
a) t-4 = 3 (i - 1/4h) = h = 3i - 3 3/4h
= t = -0.75
= h = 4
b) 3.30am = 1 inch.
Step-by-step explanation:
a) formula for point slope form = y - y1 = m(x-x1)
a) t-4 = 3(i - 1/4h) converts to t-4 = 3i - 3/4h = t = 3i- 3 3/4
x = - 0.75 y = 4 = t= -0.75 and h = 4
b) 12.15am = 4 inches
1.15am = 3.25 inches
2.15am = 2.5 inches
3.15am = 1.75inches
3.30 = 1 inches
3.15 + 15mins = 1 inch

Write an equation in slope intercept form for the line perpendicular to y = 2x - 3 that passes through the point (-3, -3)
Answer:
y=-1/2x-9/2
Step-by-step explanation:
check picture
The equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.
To find the equation of a line perpendicular to y = 2x - 3, we need to determine the slope of the original line and then find the negative reciprocal of that slope.
The original line has a slope of 2. The negative reciprocal of 2 is -1/2.
Now, we have the slope (-1/2) and the point (-3, -3) that the perpendicular line passes through.
We can use the point-slope form of a linear equation to write the equation of the line:
y - y1 = m(x - x1)
Substituting the values:
y - (-3) = (-1/2)(x - (-3))
y + 3 = (-1/2)(x + 3)
Expanding and simplifying:
y + 3 = (-1/2)x - 3/2
y = (-1/2)x - 3/2 - 3
y = (-1/2)x - 3/2 - 6/2
y = (-1/2)x - 9/2
Therefore, the equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

Point Fis on line segment EG. EG = 100, EF = 4x - 20, and FG = 2x + 30. Write an equation that you would use to solve for x, then state the value of x, and the length
of line segments EF and FG.
Step-by-step explanation:
Line segment = EG
point on a line segment = F
EG = 100
EF = 4x - 20
FG = 2x + 30
a/q, EF + FG = EG
the equation is
4x - 20 + 2x + 30 = 100
now solution for x is
→ 4x - 20 + 2x + 30 = 100
→ 6x + 10 = 100
→ 6x = 100 - 10 = 90
→ x = 90/6 = 15
therefore, value of x is 15.
and according to given information
EF = 4x - 20 = 4(15) - 20 = 60 - 20 = 40
FG = 2x + 30 = 2(15) + 30 = 30 + 30 = 60

Answer:
42.5 square units
Step-by-step explanation:
To solve, we can split this shape up into 4 known shapes:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 5 unit triangle
3.5 unit by 9.0 unit rectangle
Now let's solve these areas:
2 x 2 = 4 / 2 = 2
2 x 2 = 4
2 x 5 = 10 / 2 = 5
3.5 x 9.0 = 31.5
Then add all these values together:
2 + 4 + 5 + 31.5 = 42.5

4 over 10
2 over 8
3 over 5
4 over 12
6 over 10
3 over 6
Answer: 4/10 = 2/5
2/8 = 1/4
3/5 = 3/5
4/12 = 1/3
6/10 = 3/5
3/6 = 1/2
Step-by-step explanation:
4/10 = 2/5
4/10 is not in its simplest form.
Both 4 and 10 can be divided by 2.
Therefore, 4/10 = 2/5
2/8 = 1/4
2/8 is not in its simplest form
2 / 2 = 1
8 / 2 = 4
Both 2 and 8 can be divided by 2, therefore, 2/8 = 1/4
3/5 = 3/5
3/5 is in its simplest form
3 and 5 are prime, so they don’t have any factors other than 1 and itself so they wouldn’t be able to be simplified.
4/12 = 1/3
4/12 is not in its simplest form
4 / 4 = 1
12 / 4 = 3
4 and 12 can be divided by 4, resulting in 1 and 3. Therefore, 4/12 = 1/3.
6/10 = 3/5
6/10 is not in its simplest form
6 / 2 = 3
10 / 2 = 5
6 and 10 can both be divided by 2, resulting in 3/5. Therefore, 6/10 = 3/5
3/6 = 1/2
3/6 is not in its simplest form
3 / 3 = 1
6 / 3 = 2
Both 3 and 6 can be divided by 3, resulting in 1/2
Therefore, 3/6 = 1/2
Short Answers:
4/10 = 2/5
2/8 = 1/4
3/5 = 3/5
4/12 = 1/3
6/10 = 3/5
3/6 = 1/2

Joseph owes his mother $12.25. He borrows $6.50 more from his mother. Which of the following best represents Joseph's debt to his mother?
Answer:
18.75.
Step-by-step explanation:
If he already owes his mother 12.25 and borrows 6.50, we can add those numbers up to get the total amount of how much he owes his mother.
12.25 + 6.50 = 18.75
Therefore, Joseph's debt to his mother can be represented using the equation above.
A music store originally purchased a piano at a cost of $892.03 and marked it up 125%. After a few weeks, however, the store discounted the piano 50% in order to make room for new merchandise. What was the discounted price?
Answer:
$557.52
Step-by-step explanation:
1. Find the marked up price.
125% = 1.25
$892.03 x 1.25 = $1,115.04

the midpoint is ____
Answer:
( - 6, 1.5 )
Step-by-step explanation:
( x1, y1 ) = ( - 2, - 1 )
Here,
x1 = - 2
y1 = - 1
( x2, y2 ) = ( - 10, 4 )
Here,
x2 = - 10
y2 = 4
Formula : -
Mid - point = ( x1 + x2 ) / 2, ( y1 + y2 ) / 2
Mid - point = ( - 2 - 10 ) / 2, ( - 1 + 4 ) / 2
= - 12 / 2, 3 / 2
Mid - point = ( - 6, 1.5 )
