To solve the problem shown in the figure above you must keep on mind the following information:
1. The figure shows a parabola whose vertex is (0,0).
2. The x² indicates that the red parabola shown in the figure is vertical
3. and the sign - indicates that the red parabola opens down.
Therefore, you can conclude that the red parabola has the equation f(x)=-x²
So, the answer is B.
Answer: b. y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
time spent on history homework: 20 minutes
time spent on each math problem: 2 minutes
math problem : x
total time spent :y
So, we have to multiply each math problem (x) by the time spent on each math problem and add the 20 minutes spent on history homework.
The expression obtained is equal to the total time spent
Mathematically speaking:
y=2x+20
x can be any real number greater than or equal to 0, ( it would be 0 if there aren't any math problems)
and y is any real number greater than or equal to 20. ( 20 minutes is the minimum time spent if there aren't any math problems)
Plug in 1.5 for x, to start off. It is then simplified to : 3*(1.5)* y - 5y
Then plug in -3 for y, it's then simplified to : 3*(1.5)* -3 - 5 * (-3)
First, multiply 1.5 times 3, and that will get you 4.5. The multiply 4.5 with -3, and that will get you -13.5. Moving on, subtract -13.5 from the 5 that is being multiplied to -3, which is -15. In conclusion, -13.5 subtracted from -15 would be -28.5. Hope this helps!
