Equate the expressions for m.
  7x = 3x + 20
  4x = 20 . . . . . . . subtract 3x
  x = 20/4 = 5 . . . divide by 4

The value of x is 5.

The parabola opens:<br> O left<br> O up<br> O down<br> O right
sattari [20]

The given parabola will open; Down

<h3>How to interpret a parabola curve?</h3>

In parabolic curves, if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

Now, we are given the equation of the parabola s;

-36y = x²

divide both sides by -36 to get;

y = -x²/36

From the above it is clear that the leading coefficient is less than zero and as such the parabola will open in the downward direction.

Many people enjoy challenging themselves by running in marathons. A marathon is a 26-mile race. The runners wear numbers that id
defon
We can start by rewriting the initial equation <span>x +10y=260 in order to express how y depends on x.
</span>10y=260-x
y=26-0.1x
This is a linear function ( it's a straight line). Linear functions have two intercepts, y and x.
To find x-intercept (also called zero of a function) we set y=0 and we solve for x.
0=26-0.1x
26=0.1x
x=260
This means that at x=260 our function has a value of 0. y(x) represents a distance from the school. This means that when y(x) is 0 our athlete reached school (finished the race), so this also answers your second question. The time it takes an athlete to finish the race is 260 minutes.
The y-intercept a value of our function at x=0. This gives us a distance of our athlete from the school at the start of the race. We find this by plugin x=0 in our equation. We get that y=26 when x=0. This makes perfect sense. Our athlete is 26 miles away from high school at the start of the race.

5 ^6 − 5 ^11 = 5 x ( 1 − 5 y ) what is the value of x and y
Eva8 [605]
Is it 5^6 - 5^11 = 5x × (1-5y)?
5^6 - 5^11 = 5^(6-11) = 5^(-5) = 1/(5^5)
So 1/3125 = 5x - 5(5y)
1/3125 = 5(x-5y)
1/3125/5 = x-5y
0.000064 = x - 5y
