What is 3/x+6=x/9 ? add

Mkey [24]3 years ago

Let's solve your equation step-by-step.

3x+6=x9

Step 1: Cross-multiply.

3x+6=x9

(3)*(9)=x*(x+6)

27=x2+6x

Step 2: Subtract x^2+6x from both sides.

27−(x2+6x)=x2+6x−(x2+6x)

−x2−6x+27=0

Step 3: Factor left side of equation.

(−x+3)(x+9)=0

Step 4: Set factors equal to 0.

−x+3=0 or x+9=0

x=3 or x=−9

Car park algebra question
Svetllana [295]
You did south, north, correctly

but last one

twice north is 2 times (x+48) or 2x+96


so

s=x
n=x+48
c=4x
s+c>2x+96
subsitute s for x and 4x for c
x+4x>2x+96
5x>2x+96
minus 2x both sides
3x>96
divide both sides by 3
x>32
it cannot be equal to 32 so
the minimum value is 33 spaces in south car park

Please help!!!!! pls pls pls asap

Answer: 78

Step-by-step explanation:

First, we want to find the area of the outer triangles. Remember that the equation to finding the area of a triangle is (l x h) x 1/2. So, let’s substitute the values into the equation. It’ll be (6 x 7) x 1/2. Let’s solve! 6 x 7 = 42. Then, 42 x 1/2 = 21. But let’s not forget that we only found the area of one triangle. We still need to find the area of the other outer triangles. So, to do this, we take 21 and multiply by 3 since the other outer triangles have the same dimensions. We would get 63 as our total area for the outer triangles.

Next, we need to find the area for the inner triangle. We will use the same equation: (l x h) x 1/2. Let’s substitute! (6 x 5) x 1/2 will be our final equation. Now, let’s solve. 6 x 5 = 30. 30 x 1/2 = 15. So, as a process of elimination, our area for the inner triangle is 15.

Finally, we need to add the total areas we found together. Our total areas were 63 and 15. Let’s put this into an equation: 63 + 15 = ?. So, 63 + 15 = 78. So, after a long process, 15 is our answer!

Hope this helped!

Determine if the function is an even function, an odd function or neither. > = −6x² – 5x² −2 even neither odd​
mel-nik [20]

Answer: even

Step-by-step explanation:

A function is even if f(x)=f(-x), and odd if f(x)=-f(-x). If a function satisfies neither of these, it is neither even nor odd.

f(x)_=-6x^{2}-5x^{2}-2=-11x^{2}-2\\\\f(-x)=-11(-x)^{2}-2=-11x^{2}-2\\\\\therefore f(x)=f(-x)

Therefore, the function is <u>even</u>.
