This is an easy one.
first you move 2/3 to the other side
x=3-2/3
so you get
x=1/3
We use the law of correspondence that is
Hypotenuse = Hypotenuse Leg = Leg
3y + x = y + 5
and
y - x = x + 5 --------------------------------- work on your first problem to find x
x = -2y + 5
now you can plug this in to your second equation to sub in for the x
y - ( -2y + 5 ) = ( -2y + 5 ) + 5 y + 2y - 5 = -2y + 10 3y - 5 = -2y + 10 5y = 15 y = 3
Now you can plug back in to solve for x
3y + x = y + 5 3(3) + x = (3) + 5 9 + x = 8 x = -1
so y = 3 and x = -1
THE PARABOLA OPENS DOWN (WHICH IS MAXIMUM ) AND X=1/2
Answer: Yes, the time it takes to run a 100 meter race is a function of the speed you run.
In a function, there is an input and only one corresponding output. In the case of a race time, it depends on your speed.
A person with a slower speed will have a longer race time.
A person with a higher speed will have a shorter race time.
Answer:
3/7
Step-by-step explanation:
add 1/2 and 5/2=3, make /7 in to fraction: 3/7
= 3/7 - 1/2 x 2/3 + 1/3
multiply
= 3/7 - 1/3 + 1/3
cancel out the 1/3s
= 3/7
