Answer:
A= .75 B= .75
Step-by-step explanation:
Plug in .75. 5(.75) + 3(.75) = 6
7(.75) + 9(.75) = 12
You would turn a to x and b to y to get ---> 5x + 3y = 6 and 7x + 9y = 12 -----> then you would multiply the first equation ^^^^^ by 3 to cancel to give you 15x + 9y = 18 (I did that to get 9y and cancel out the 9y in the other equation) next do 15x + 9y = 18 - 7x + 9y = 12 to get ----> 8x = 6 ---> divide by 8 to get ---> x = .75
Hope this helped!!
GHI and JHK can be assumed to be on the same line/plane. The two angles add to be 180 degrees, meaning the line that connects them (I'm assuming GHK) is a straight line of 180 degrees.
Answer:
use calcES to get d zeros of the polynomial without any stress
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
