Answer:
Step-by-step explanation:
we have that
The scale drawing is
we know that
Using proportion find out the actual dimensions of the volleyball court
Let
x -----> drawing court lengths in cm
y ----> court lengths in cm
For x=40 cm
For x=80 cm
Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
For x=40 cm, y=900
substitute
-----> 
The equation is
Answer:
Step-by-step explanation:
Our function is : 3x²-3x-1
- 3x²-3x+2=2
- 3x²-3x-1+3=2
- 3x²-3x-1= -1
- the number that gives us -1 is 1 (from the graph)
so x is 1
- 3x²-3x-1= x+1 ⇒3x²-4x-2 = 0
- Δ(the dicriminant)= (-4)²-4*3*(-2)= 16+24 =40
- two solution x and y
- x= (4-√40)/6 and y= (4+√40)/6
- x= -0.38 and y = 1.7
- so the estimations are -0.38 and 1.7
If you see that the temperature rose in the next 4 hours and the temperture was taken at noon so the answer would be D there was no change in temperature
2x3= 6
18÷6= 3
So, 3x4 = 12
To convert a mixed number to an improper, first, multiply the denominator of the fraction and the whole number of the fraction. Then, add the numerator to the product of the denominator and the whole number.
For example, 3 1/4. Multiply the 3 and 4 to get 12. Then add the one and you get 13. Lastly, take your sum (13 in this case) and put it over the original denominator (4) Your answer is 13/4. Hope that helps :)
