Answer:
Option C (1, 0)
Step-by-step explanation:
We have a system with the following equations:
The first equation is a parabola.
The second equation is a straight line
To solve the system, substitute the second equation in the first and solve for x.
Simplify
You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.
These numbers are -1 and -1
Therefore
Finally the solutions are
Answer:
2 3/4
Step-by-step explanation:
One number be x
x+(x+1)+(x+2)=63
x+x+1+x+2=63
3x+3=63
3x=63-3
3x=60
x=60:3
x=20
smallest number = x=20
middle <span>number = x+1= 20+1=21
</span>largest<span><span><span> number = x+2</span> =20+2= 22</span>

Answer:
45 feet
Step-by-step explanation:
To find the width of the model, we need to find the scale of the model to the actual tower.
Since we know the height of both towers, we can use that as the basis.
24 inches : 60 feet
12 inches : 30 feet
6 inches : 15 feet
So the width of the tower is 18 inches wide.
18 inches will then be equal to 12 + 7 inches : 30 + 15 feet
18 inches : 45 feet
Answer:
The base of the window is 7.5 feet long.
Step-by-step explanation:
The area of a parallelogram can be found with the formula A = bh
Plug in the known values to get 30 = 4b
30 = 4b
30/4 = b
7.5 = b
