Answer:
The correct option is A
A) -10 ≤ x ≤ 10 , -10 ≤ y ≤ 10
Step-by-step explanation:
We have been given a system of equation:
y = -13x + 17
y = 5x - 23
We have to determine the best window range from the following options:
A) -10 ≤ x ≤ 10 , -10 ≤ y ≤ 10
B) -20 ≤ x ≤ 0 , -20 ≤ y ≤ 0
C) 0 ≤ x ≤ 20, 0 ≤ y ≤ 20
D) 20 ≤ x ≤ 40 , 20 ≤ y ≤ 40
The graph of both the equation is attached below, we can see that the graph shows the solution at the point (2.222, -11.869), where x is positive and y is negative
Now consider the options
Option A includes the solution
Option B doesn't show positive values for x
Option C doesn't show negative values for y
Option D doesn't include the x or y part of the solution
Answer:
The percentage of the price of television reduced to <u>20%</u>.
Step-by-step explanation:
Given:
The price of a television was reduced $250 to $200.
Now, to find the percentage of the reduced price of television.
So, to get the reduced amount of television:
Old price = $250.
New price = $200.
Reduced amount = $250 - $200 = $50.
Now, to get the percentage of price reduced:




Therefore, the percentage of the price of television reduced to 20%.
Answer:
x^2+7x+12
Step-by-step explanation:
(x+3) (x+4)
FOIL
first: x*x = x^2
outer: 4x
inner: 3x
last: 3*4 =12
Add them together
x^2 +4x+3x+12
x^2+7x+12
