Answer:
slope = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = [tex]\frac{0-2}{3-0}[/tex] = [tex]\frac{-2}{3}[/tex] = - [tex]\frac{2}{3}[/tex]
Answer:
-2/3
Step-by-step explanation:
The equation for slope is y2-y1 over x2-x1.
Or you can easily do rise over run.
Lets use the point (0,3.) So, we want to calculate slope, but the only other direct point is (0,2) so lets also use that.
If we start at the point (0,2) and go down 2 units, we just have to go over 3 units to get to (0,3) so thats convienient.
The rise is the -2 units, since you go down 2 units to get to the second point. You also have to run 3 units over to get to the second point.
The run is 3, and the rise is -2.
Rise over run
-2 (rise) over 3 (run)
-2/3
-2/3 is the slope.

Tavon has a gift card of $90 that loses $2 for each 30-day period not used. He has another gift card for $70 that loses $1.50 for each 30-day period not used. What will the value of each card be when they have equal value?
Answers
Answer:
$10
Step-by-step explanation:
Let the number of 30 day periods be x.
[tex]90-2x=70-1.5x \\ \\ 20=0.5x \\ \\ x=40[/tex]
When x=40, the value is 90-2(40)=$10.
The value of each card will be $ 10 after 40 periods, where the value of the first and second cards are equal.
Given data:
Let x represent the number of 30-day periods that have passed since the gift cards were obtained.
For the first gift card with $90 initial value and losing $2 for each 30-day period:
Value of the first card = Initial value - Loss per period * Number of periods
Value of the first card = $90 - $2 * x
For the second gift card with $70 initial value and losing $1.50 for each 30-day period:
Value of the second card = Initial value - Loss per period * Number of periods
Value of the second card = $70 - $1.50 * x
Now, to find when the two cards have equal value x:
Value of the first card = Value of the second card
$90 - $2 * x = $70 - $1.50 * x
On simplifying the equation:
$90 - $70 = $2 * x - $1.50 * x
$20 = $0.50 * x
x = $20 / $0.50
x = 40
After 40 periods of 30 days each, the two cards will have equal value.
Now, determine the value of each card at this point:
Value of the first card = $90 - $2 * 40 = $90 - $80 = $10
Value of the second card = $70 - $1.50 * 40 = $70 - $60 = $10
Hence, both cards will have a value of $10 when they have equal value after 40 periods.

pls mark as brainliest
Answer:
Step-by-step explanation:
You have to figure out what has to multiply by itself to get to that number.
So for example, 121. The square root is more than 10 because 10 times 10 equals 100. It's less than 15 because 15 times 15 is a little over 200. If you have your multiplication tables memorized, you'd know that 11 multiplied by itself is 121. Therefore, the square root to 121 is 11. Hope this helps! (:

Given f(x) = 4x + 1 and g(x) = x2 − 2, which of the following is an expression for f(g(x))?
Answers
The value of the expression of the composite function f(g(x)) = 4x^2 - 3
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to determine the value of the expression?The given parameters are:
f(x) = 4x + 1
g(x) = x^2 - 1
The composite function is given as
f(g(x)
The above composite function is calculated as
f(x) = 4x + 1
Substitute x for g(x) in the above function
So, the above function becomes
f(g(x)) = 4g(x) + 1
Substitute x^2 - 1 for g(x) in the above function
So, the above function becomes
f(g(x)) = 4(x^2 - 1) + 1
Evaluate the products in the above equation
So, we have
f(g(x)) = 4x^2 - 4 + 1
Evaluate the sum in the above equation
So, we have
f(g(x)) = 4x^2 - 3
Hence, the value of the composite function f(g(x)) = 4x^2 - 3

Answer:
marked price = Rs. 3900
Step-by-step explanation:
The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.
The marked price is Rs. 3900.
_____
Check
A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.
