Step 1 is to factor everything!
After factoring you will get:
x-5 over (x+2)(x+5) times x+4 over (x-3)(x+4)
Step 2 is to remove the duplicate factors!
Remove x+4 and x+5
x-5 over (x+2)(x-5) times 1 over x-3 = 1 over x+2 times 1 over x-3
Step 3 is to multiply the numerators and the denominators.
End result is 1 over (x+2)(x-3)
Answer:
Step-by-step explanation:
2 x 40 = 80
200 x 2 = 400
80 x 7 = 560
Answer:
Domain: [0, 40]
Range: [0, 20]
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Range is the set of y-values that are outputted by function f(x)
- Interval Notation - [a, b] denotes inclusive, (a, b) denotes exclusive
Step-by-step explanation:
According to the graph, we see that our x-values span from 0 to 40. Since both are closed dots, they are included in the domain:
Interval Notation [0, 40]
Inequality Notation 0 ≤ x ≤ 40
According to the graph, we see that our y-values span from 0 to 20. Since both are closed dots, they are included in the range:
Interval Notation [0, 20]
Inequality Notation 0 ≤ y ≤ 20
Answer:
The answer for this problem is 14.825
Step-by-step explanation:
There are about three steps for this problem
The first is finding out what is 45% of 3.5 yds. You do this by multiplying 3.5 and .45 and you get 1.575
The second step is finding the second carpets length. All you have to do is add the number we got from multiplication which is 1.575 to 3.5 and you get 5.075. The reason we added those numbers is because the problem says the second carpet is 45% "longer" than the first carpet.
The third and final step is to add up all three values and you get 14.825!
Answer:
Step-by-step explanation:
May we see the whole picture, but if you are confident in the numbers but not the placement this should help you!
(x,y)
The x-intercept would be the first number so (x,y)
And the y-intercept would be the second number (x,y)
Hope this helps ya! Keep smiling!
