It tells us that:

(-2,4)
(-1,3)
(1,6)
(3,5)
(4,8)

Look at (3,5) ... it tells us that x = 3 and y = 5

So y = 5

WILL MARK BRAINLIEST!!!
wariber [46]

f(x) = -9x^4 + 5x + 3\\\\ f(-x)= -9(-x)^4 + 5\cdot(-x) + 3=-9x^4-5x+3\\\\ f(-x)\not =f(x)\implies \text{ not even}\\\\ -f(x)=-( -9x^4 + 5x + 3)= 9x^4 - 5x - 3\\\\ -f(x)\not =f(-x) \implies \text{ not odd}

Neither

Solve algebraically for x
Anton [14]
3x + 1 = (x-1)^2
3x + 1 = x^2 - 2x + 1
0 = x^2 -5x
0 = x(x-5)
x = 0,5

Hope this helps!

The 2 main support rods for a barbeque grill are each 7.5 cm from the centre of the
sukhopar [10]

Answer:

  58.1 cm

Step-by-step explanation:

The length of each support rod can be found using the Pythagorean theorem. The geometry can be modeled by a right triangle, such that the distance from centre is one leg and half the length of the rod is the other leg of a triangle with hypotenuse equal to the radius of the grill.

__

<h3>Pythagorean theorem</h3>

The theorem tells us that the sum of the squares of the legs of a right triangle is the square of the hypotenuse. For legs a, b and hypotenuse c, this is ...

  c² = a² +b²

<h3>application</h3>

For the geometry of the grill, we can define a=7.5 and c=30. Then b will be half the length of the support rod.

  30² = 7.5 +b²

  b² = 900 -56.25 = 843.75

  b = √843.75 ≈ 29.0473

The length of each support rod is twice this value, so ...

  rod length = 2b = 2(29.0473) = 58.0947

Each support rod is about 58.1 cm long.
