From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
Answer:
It takes 2.4 hours to travel 480 miles.
Step-by-step explanation:
From the graph race car is moving at 100 miles in 0.5 hours. So, in 1 hour, car could travel 2*100 =200 miles per hour.
So, we can set up equation as
y= 200x.
Plug in y as 480 then solve for x.
480 =200x
Divide both sides by 200
2.4=x
So, it would take 2.4 hours.
Answer:
ok so the graph tells you 24 seconds by 4 ounces
Step-by-step explanation:
The point where both lines meet is the point where they are both equal.
The point where both lines meet is (24,4)
Since the x-axis represents seconds the x-coordinate will represent the number of seconds it takes for them to be equal which is 24.
Since the y-axis represents ounces the y-coordinate will represent the number of ounces they have when they are equal which is 4.
Just divide distance by gasoline used.. B car is 426 divided 12 is 35.5 miles per gallon
Responder:
120 maneras.
Explicacion paso a paso:
Cinco tipos diferentes de semillas.
El numero de formas de organizar, n, a diferencia de los objetos en una linea es n!
Entonces, para sembrar 5 tipos diferentes de flores, serian 5!
5! = 5 * 4 * 3 * 2 * 1 = 120 vias.
Por lo tanto, hay 120 formas de sembrar las cinco semillas.
