1.Simplified each one
2/5 (both divided by 7) , 1/2 (divided by 21)
2.Make them into integer
(2/5 )*(2/2)=4/10 , (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5

How much does 12 go into 11

Anni [7]

It goes into it 0 times but what you can do is 11 going into 12 which would give you 1.1 instead of you making it a remainder.

Please help asap I genuinely cannot figure this out

Gemiola [76]

Answer:

Step-by-step explanation:

We can use the factored form of the quadratic equation, given by:

$y=a(x-p)(x-q)$

Where a is the leading coefficient and p and q are the zeros.

We have zeros x = -2 and x = 3. So, let p = -2 and q = 3:

$y=a(x+2)(x-3)$

Next, we are given that our y-intercept is (0, -30).

In other words, when x = 0, y = -30. So:

$-30=a(0+2)(0-3)$

Solve for a:

$-30=-6a\Rightarrow a=5$

Hence, our factored equation is:

$\displaystyle y=5(x+2)(x-3)$

For the standard form, expand:

$y=5(x^2-3x+2x-6)$

Simplify:

$y=5(x^2-x-6)$

Distribute:

$y=5x^2-5x-30$

Our answer is C.
