Answer:
x+y<u><</u> 45
Step-by-step explanation:
the sum of x and y is equal or greater than 45 minutes so the above is the answer
Answer:
$0.51
Step-by-step explanation:
Hello! Using what we know, the price of the candy bar at the moment is $1.53, triple the price from 10 years ago. So, triple cents would technically be $0.03. We divide $1.53 and $0.03 and get 51! But, it would not make sense for the price ten years ago to be 51 then go to 1.53, so we make 51 a decimal, 0.51. We can check to see if this correct, by doing 0.51 times 3, because the price is tripling, and we get $1.53! Have an awesome day! :)
The vertex is (-1,1)
Explanation
The vertex formula to find the x coordinate of the formula is -b/2a
So we plug in the values into the formula which is
-4/2(2)
Simplify it
-4/4
=-1
-1 is now the x cord of the vertex.
So now we will plug in the x into the quadratic equation which is 2x^2+4x+3
2(-1)^2 + 4(-1) + 3 = 2 -4 +3
Simplify it
5 - 4= 1
Y=1
So the Coordinates of the vertex is (-1,1)
Mrs. Walters : 360/25 = 14.4 miles per gallon
Mr. Walter : 480/32 = 15 miles per gallon
Mr. Walter is getting better mileage per gallon
Answer:
<h3>Part A: Function type</h3>
Car 1 . Exponential function
<u>The value ratios are constant:</u>
- 40500/45000 = 36450/4050 = 32805 /36450= 0.9
Car2. Linear function
<u>The value differences are constant:</u>
- 45000 - 42000 = 42000 - 39000 = 39000 - 36000 = 3000
<h3>Part B: Equations</h3>
<u>Car 1</u>
<u>Car 2</u>
<h3>Part C: Value after 13 years</h3>
<u>Car 1</u>
- f(13) = 45000*0.9¹³ = $11438
<u>Car 2</u>
- f(13) = 45000 - 3000*13 = $6000
Car 1 will have a greater price
