Suppose that a phone that originally sold for $800 loses 3/5 of its value each year after it is released.
After 2 years, how much is the phone worth?
Write an equation for the value of the phone, , years after it is released.
Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.
Name the steps of solving 5x+4=40
Answer:
Step-by-step explanation:
Simplifying
5x + -4 = 40
Reorder the terms:
-4 + 5x = 40
Solving
-4 + 5x = 40
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 5x = 40 + 4
Combine like terms: -4 + 4 = 0
0 + 5x = 40 + 4
5x = 40 + 4
Combine like terms: 40 + 4 = 44
5x = 44
Divide each side by '5'.
x = 8.8
Simplifying
x = 8.8

Write the equation of the line that passes through each pair of point (1,2) (-1,-3)
Answer: y = 3
Step-by-step explanation:
So, we must find an equation of a line that passes through these two points such that we find the slope first as,
m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that
y - y1 = m(x - x1). Next,
y - 3 = 0(x - (-1))
y - 3 = 0..............Then add 3 such that the equation of a line is
What is the total cost of a $136 radio that has a 25% discount and sales tax is 5%?
PLEASE HELPPP
Answer: Price Before Tax: $102.00
Tax: $5.10
Final Price: $107.10
Original Price + Tax: $142.80
Total Savings: $35.70
Savings:
35.70
Tax:
5.10
Total Payment:
107.10
Step-by-step explanation:
Answer:
107.1
Step-by-step explanation:
136 × 25% = 34
136 - 34 = 102 (Price after the discount)
102 × 5% = 5.1
102 + 5.1 = 107.1 (Price after the discount and sales tax)

PLEASE HELP!!! Find the slope of the line that passes through the points (-1,7) and (0,-3).
Answer:
-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-7)/(0-(-1))
m=-10/(0+1)
m=-10/1
m=-10
Answer:
The slope is -10.
Step-by-step explanation:
Goal
Find the value of m/Find the slope.Given
Two coordinate points which are (-1,7) and (0,-3).Step 1
Use the slope formula which is rise over run also known as changes of y over changes of x.[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
From the given coordinate points, substitute the values in the formula.
[tex]m = \frac{7 - ( - 3)}{ - 1 - 0} \\ m = \frac{7 + 3}{ - 1} \longrightarrow \frac{10}{ -1} \\ m = - 10[/tex]
Therefore, the value of m or slope is -10.
!!will give brainliest!! If you want addition to be done before multiplication, what do you need to add to the problem?
I beive your doing "Order of Operations"
Heres some information.
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to preform multiplication and division from left to right. Next, add and subtract from left to right.

If you deposit $24,500 into a bank account paying 6% annual interest compounded
semi-annually for 5 years, how much interest will you earn? Round to the nearest cent.
Answer:
$7,719.33
Step-by-step explanation:
$24,500 x 0.06 = $1,470
($24,500 + $1,470) x 0.06 = $1,558.20
($24,500 + $1,558.20) x 0.06 = $1,563.49
($24,500 + $1,563.49) x 0.06 = $1,563.81
($24,500 + $1,563.81) x 0.06 = $1,563.83
$1,470 + $1,558.20 + $1,563.49 + $1,563.81 + $1,563.83 = $7,719.33
1. The scale of a map is 1:1000. What are the actual dimensions of a
rectangle which appears as 4 cm by 3 cm on the map? What is the area
on the map in cm2 ?What is the actual area in m2?
Answer:
Step-by-step explanation:
4 cm × 1000 = 4000 cm = 40 meters
3 cm × 1000 = 3000 cm = 30 meters
A 4 cm by 3 cm section on the map represents 40 m by 30 m.
area = 40 m × 30 m = 1200 m²
the sequence of the numbers below is missing an eighth value. which of the following is the missing value? sequence: 5, 6, 8, 11, 15, 20, 26, __, 41
Answer:
D - 33
Step-by-step explanation:
From 5 to 6, the number is increasing by 1. Then from 6 to 8, it increases by 2. From 8 to 11 it increases by 3. This pattern continues throughout the entire sequence. Since between 20 and 26, it increases by 6, 26+7 should equal the number between 26 and 41. This number would be 33.
The equation for compound interest is A=P(1+rn)nt, where P is the initial amount invested, r is the interest rate as a decimal, n is the number of times compounded annually, and t is the number of years.
Determine the value of the account if the initial investment is $8,000 compounded monthly at a rate of 6% after 10 years.

An oven is set at 176.8°C. Marla increases the temperature by 23.8°C.
What is the final oven temperature?
Answer:
200.6 degrees Celsius
We have the given number, 176.8 degrees Celsius, and we add or increase it by 23.8 degrees.
176.8 + 23.8 = 200.6
Our final answer is 200.6 degrees Celsius.
~Hope this helps~
Answer:
200.6'C or 461.2'F
Step-by-step explanation:
176.8'C
+ 23.8'C
--------------
200.6'C
To make 'F, we must add 30, then multiply by 2.
200.6'F
+ 30.0'F
--------------
230.6'F
